Javascript端加密java服务端解密
通常我们会通过htts来保证传输安全,但如果我们不用https,如何通过javascript来保证浏览器端发送的参数进行加密,并且通过RSA算法来处理。
这里我们可以利用jquery的一个加密插件jcryption来处理,可以参考
http://jcryption.org/#examples
现在版本是3.0 但是没有java端的实现,下次有时间再研究。现在这个用的是1.1的版本
这个可以在
http://linkwithweb.googlecode.com/svn/trunk/Utilities/jCryptionTutorial 获取
不过他的服务端有个缺陷我修改了。
接来大致介绍如下:
1. 首先服务端有产生publicKey的servlet:
package com.gsh.oauth.auth.servlet;
import java.io.IOException;
import java.security.KeyPair;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.gsh.oauth.auth.util.JCryptionUtil;
/**
* Servlet implementation class EncryptionServlet
*/
public class EncryptionServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* Default constructor.
*/
public EncryptionServlet() {
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#service(HttpServletRequest request, HttpServletResponse response)
*/
protected void service(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
int KEY_SIZE = 1024;
if (request.getParameter("generateKeypair") != null) {
JCryptionUtil jCryptionUtil = new JCryptionUtil();
KeyPair keys = null;
//if (request.getSession().getAttribute("keys") == null) { //这里注释掉 否则第二次请求会500
keys = jCryptionUtil.generateKeypair(KEY_SIZE);
request.getSession().setAttribute("keys", keys);
//}
StringBuffer output = new StringBuffer();
String e = JCryptionUtil.getPublicKeyExponent(keys);
String n = JCryptionUtil.getPublicKeyModulus(keys);
String md = String.valueOf(JCryptionUtil.getMaxDigits(KEY_SIZE));
output.append("{\"e\":\"");
output.append(e);/Files/linugb118/bcprov-jdk15-1.46.jar.zip
output.append("\",\"n\":\"");
output.append(n);
output.append("\",\"maxdigits\":\"");
output.append(md);
output.append("\"}");
output.toString();
response.getOutputStream().print(
output.toString().replaceAll("\r", "").replaceAll("\n", "")
.trim());
} else {
response.getOutputStream().print(String.valueOf(false));
}
}
}
2. Client例子
<html>
<head>
<title>Login form</title>
</head>
<meta http-equiv="Content-Type"
content="text/html; charset=utf-8">
<script src="../js/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="../js/jquery-ui-1.8.2.custom.min.js"
type="text/javascript"></script>
<script type="text/javascript"
src="../js/security/jquery.jcryption-1.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var $statusText = $('<span id="status"></span>').hide();
$("#status_container").append($statusText);
$("#lf").jCryption({
getKeysURL:"/gsh/oauth/encryption?generateKeypair=true",
beforeEncryption : function() {
$statusText
.text("Test Code")
.show();
return true;
},
encryptionFinished : function(
encryptedString,
objectLength) {
$statusText
.text(encryptedString);
return true;
}
});
});
</script>
<body>
<form id="lf" action="/gsh/oauth/authorization"
method="post">
<fieldset><legend>login</legend>
<div>
<div>client_id:<br>
<input type="text" size="45" name="client_id" value=""></div>
<div>redirect_uri:<br>
<input type="text" size="45" name="redirect_uri" value=""></div>
</div>
<div>loginid:<br>
<input type="text" size="45" name="loginid" value=""></div>
</div>
<div>password:<br>
<input type="password" size="45" name="password" value=""></div>
</div>
<div>
<p><input type="submit" /><span id="status_container"></span></p>
</div>
</fieldset>
</form>
</body>
</html>
上面看代码可以看出 他通过/gsh/oauth/encryption?generateKeypair=true来先请求获取public 然后通过jcryption进行加密 然后post到服务端。Encryption就是上面的EncryptionServlet。
通过浏览器工具可以看到表单里面的数据加密为
jCryption=95f1589502288050e08b4bd8b1a360341cf616d9054531b85a6ef85783c1723b46686ec454ee81f1304fa2370ce24c4d9c06f84d47aa4bdf99310ae12b514db19bfcc325f3a39a584c23b1546550f4e0635c12486f2fd84dec137e1c61cfa775dfa3057a1f0154712aaba0af0cc61810282780f15bed909c24a184e66ab39f2e
3. 目标servlet(authorization)的解密
public class Authorization extends HttpServlet {
protected void doGet(HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse) throws ServletException,
IOException {
PrintWriter out = httpServletResponse.getWriter();
KeyPair keys = (KeyPair) httpServletRequest.getSession().getAttribute("keys");
String encrypted = httpServletRequest.getParameter("epCryption");
String client_id = null;
String redirect_uri = null;
String loginid = null;
String password = null;
try {
String data = JCryptionUtil.decrypt(encrypted, keys);
httpServletRequest.getSession().removeAttribute("keys");
Map params = JCryptionUtil.parse(data, "UTF-8");
client_id = (String) params.get("client_id");
redirect_uri = (String) params.get("redirect_uri");
loginid = (String) params.get("loginid");
password = (String) params.get("password");
} catch (Throwable e) {
e.printStackTrace();
}
}
}
上面至少片段,需要相关的js和java问题,请在svn上面获取。另外还需要bcprov-jdk15-1.46.jar
可以在http://mvnrepository.com/artifact/org.bouncycastle/bcprov-jdk15/1.46
获取。
在使用cas3的时候,往往有这样的需求,希望每个应用有个独立的登录页面
这块cas 官方文档有一些说明
https://wiki.jasig.org/display/CAS/Using+CAS+without+the+Login+Screen
首先从官方的角度,不建议使用多个登录页面,这样对安全会形成短板。但是
用户需求之上,如果我们要实现,有下面几种方式
1.通过参数来判断css来改变布局甚至一些图片,典型cas里面的default-view中
casLoginView.jsp 里面就有这样的描述,通过描述可以看出他通过不同css来区分
weblogin和mobilelogin。
比如片段
<c:if
test="${not empty requestScope['isMobile'] and not empty mobileCss}">
<meta name="viewport"
content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
<!--<link type="text/css" rel="stylesheet" media="screen" href="<c:url value="/css/fss-framework-1.1.2.css" />" />
<link type="text/css" rel="stylesheet" href="<c:url value="/css/fss-mobile-${requestScope['browserType']}-layout.css" />" />
<link type="text/css" rel="stylesheet" href="${mobileCss}" />-->
</c:if>
2.cas服务端(或者各种应用中)建立一个独立的form页面
参考:https://wiki.jasig.org/display/CAS/Using+CAS+from+external+link+or+custom+external+form
比如:
在cas(或者各种的应用页面) web-inf/ 页面添加testlogin.html
代码:
<html>
<head />
<body>
<form method="GET" action="http://192.168.2.109:8080/cas/login">
<p>Username : <input type="text" name="username" /></p>
<p>Password : <input type="password" name="password" /></p>
<p>Remember me : <input type="checkbox" name="rememberMe" value="true" /></p>
<p><input type="submit" value="Login !" /></p>
<input type="hidden" name="auto" value="true" />
<input type="hidden" name="service" value="http://localhost/user/checklogintocas.php" />
</form>
</body>
</html>
casLoginView.jsp
实现自动提交功能:
...
<%@ page contentType="text/html; charset=UTF-8" %>
<%
String auto = request.getParameter("auto");
if (auto != null && auto.equals("true")) {
%>
<html>
<head>
<script language="javascript">
function doAutoLogin() {
document.forms[0].submit();
}
</script>
</head>
<body onload="doAutoLogin();">
<form id="credentials" method="POST" action="<%= request.getContextPath() %>/login?service=<%= request.getParameter("service") %>">
<input type="hidden" name="lt" value="${loginTicket}" />
<input type="hidden" name="execution" value="${flowExecutionKey}" />
<input type="hidden" name="_eventId" value="submit" />
<input type="hidden" name="username" value="<%= request.getParameter("username") %>" />
<input type="hidden" name="password" value="<%= request.getParameter("password") %>" />
<% if ("true".equals(request.getParameter("rememberMe"))) {%>
<input type="hidden" name="rememberMe" value="true" />
<% } %>
<input type="submit" value="Submit" style="visibility: hidden;" />
</form>
</body>
</html>
<%
} else {
%>
<jsp:directive.include file="includes/top.jsp" />
...
<jsp:directive.include file="includes/bottom.jsp" />
<%
}
%>
3.第三种方法 其实是第二种方法的启发,直接把用if-else 把多个页面组合在一起,通过参数来判断显示。(最好能可以支持多套casLoginView.jsp 不过研究下来好像比较难,也许cas开发者也是为了怕再次开放的人用太多灵活的多套casLoginView.jsp 页面跳来跳去把项目搞混吧。)
之前在
安装memcache时有提到memcached客户端是叫memcache,其实还有一个基于libmemcached的客户端叫memcached,据说性能更好,功能也更多。
memcache的官方主页:
http://pecl.php.net/package/memcachememcached的官方主页:
http://pecl.php.net/package/memcached以下是我安装Memcached版本的PHP模块的过程记录:
wget
http://download.tangent.org/libmemcached-0.48.tar.gztar zxf libmemcached-0.48.tar.gz
cd libmemcached-0.48
./configure --prefix=/usr/local/libmemcached --with-memcached
make
make install
wget
http://pecl.php.net/get/memcached-1.0.2.tgztar zxf memcached-1.0.2.tgz
cd memcached-1.0.2
/usr/local/webserver/php/bin/phpize
./configure --enable-memcached --with-php-config=/usr/local/webserver/php/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached
make
make install
在php.ini中加入
extension=memcached.so
完成
另:
在安装libmemcached时,如果只用./configure,可能会提示:
checking for memcached… no
configure: error: “could not find memcached binary”
两者使用起来几乎一模一样。
$mem = new Memcache;
$mem->addServer($memcachehost, '11211');
$mem->addServer($memcachehost, '11212');
$mem->set('hx','9enjoy');
echo $mem->get('hx');
$md = new Memcached;
$servers = array(
array($memcachehost, '11211'),
array($memcachehost, '11212')
);
$md->addServers($servers);
$md->set('hx','9enjoy');
echo $md->get('hx');
memcached的方法比memcache多不少,比如getMulti,getByKey,addServers等。
memcached没有memcache的connect方法,目前也还不支持长连接。
memcached 支持 Binary Protocol,而 memcache 不支持,意味着 memcached 会有更高的性能。
Memcache是原生实现的,支持OO和非OO两套接口并存,memcached是使用libmemcached,只支持OO接口。
更详细的区别:
http://code.google.com/p/memcached/wiki/PHPClientComparisonmemcached服务端是集中式的缓存系统,分布式实现方法是由客户端决定的。
memcached的分布算法一般有两种选择:
1、根据hash(key)的结果,模连接数的余数决定存储到哪个节点,也就是hash(key)% sessions.size(),这个算法简单快速,表现良好。然而这个算法有个缺点,就是在memcached节点增加或者删除的时候,原有的缓存数据将大规模失效,命中率大受影响,如果节点数多,缓存数据多,重建缓存的代价太高,因此有了第二个算法。
2、Consistent Hashing,一致性哈希算法,他的查找节点过程如下:
首先求出memcached服务器(节点)的哈希值,并将其配置到0~232的圆(continuum)上。然后用同样的方法求出存储数据的键的哈希值,并映射到圆上。然后从数据映射到的位置开始顺时针查找,将数据保存到找到的第一个服务器上。如果超过2的32次方后仍然找不到服务器,就会保存到第一台memcached服务器上。
memcache在没有任何配置的情况下,是使用第一种方法。memcached要实现第一种方法,似乎是使用(未确认):
$md->setOption(Memcached::OPT_HASH, Memcached::HASH_CRC);
第二种一致性哈希算法:
memcache在php.ini中加
Memcache.hash_strategy =consistent
Memcache.hash_function =crc32
memcached在程序中加(未确认)
$md->setOption(Memcached::OPT_DISTRIBUTION, Memcached::DISTRIBUTION_CONSISTENT);
$md->setOption(Memcached::OPT_HASH, Memcached::HASH_CRC);
或
$mem->setOption(Memcached::OPT_DISTRIBUTION,Memcached::DISTRIBUTION_CONSISTENT);
$mem->setOption(Memcached::OPT_LIBKETAMA_COMPATIBLE,true);
一些参考文档:
memcached分布测试报告(一致性哈希情况下的散列函数选择):
http://www.iteye.com/topic/346682php模块memcache和memcached区别:
http://hi.baidu.com/dong_love_yan/blog/item/afbe1e12d22e7512203f2e21.htmlPHP模块:Memcached > Memcache:
http://hi.baidu.com/thinkinginlamp/blog/item/717cd42a11f6e491023bf67a.html20110509@@UPDATE:
如果安装libmemcached有如下出错提示:
make[2]: *** [clients/ms_conn.o] Error 1
make[2]: Leaving directory `/www/soft/libmemcached-0.48'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/www/soft/libmemcached-0.48'
make: *** [all] Error 2
可在configure时增加--disable-64bit CFLAGS="-O3 -march=i686"
即:./configure --prefix=/usr/local/libmemcached --with-memcached --disable-64bit CFLAGS="-O3 -march=i686"
1. windows里面出现“拒绝访问”, 那需要通过管理员身份运行cmd
2. 安装服务时候指定的ini路径需要注意,应该指定你现在mysql目录现有的ini文件
如mysqld --install mysql --defaults-file="C:\MySQL5\my.ini"
现象: 执行demo,比如helloexample ,点击“run as mule application”,弹出框“Could not find the main class.Program will exit”
控制台出现:
java.lang.NoClassDefFoundError: org/mule/tooling/server/application/ApplicationDeployer
Exception in thread "main"
解决方法: 是因为jdk 有问题,在mule官网上要求
Before installing Mule Studio, ensure that the host machine has one of the following Java Development Kit versions installed on it:
- Standard Edition 1.6.0_26 (also known as JDK SE 6 Update 26) or more recent
- Enterprise Edition 1.6u3 (JDK EE 6 Update 3) or more recent
- Any version (SE or EE) of JDK 7
在java build path--》libraries 选择jre system library 为jdk1.7就可以。
1. serviceMix 特点:
支持的协议有:
File;FTP;Http/s;jms;smtp;soap;tcp;xmpp
与其他引擎的支持:
Apache Camel;apache cxf;apache ode;drools;os workflow;pojos;quartz;scripting;saxon Xquery and xslt;ws-notification
支持的安全:
JAAS,WS-Security
与web 容器的集成
JBoss,Geronimo,jetty,tomcat,weblogic,websphere
2. eclipse IDE tooling for serviceMix
http://eclipse.org/stp
http://spagic.com
http://sopera.de/en/products/sopera-servicemixtools
3. 安装:
- 官方下载http://servicemix.apache.org/downloads.html.并解压
- 进入bin目录执行servicemix.bat或者shell script
- Sericemix是osgi结构的,
通过osgi:list 命令可以查看所有有效的osgi bundles
通过osgi:list | grep camel 命令 查看camel相关的bundles
通过log:display命令 来显示日志
通过log:display-exception 显示最近的异常日志
通过log:set DEBUG 设置日志的级别
通过log:display | grep DEBUG 显示只是debug级别的日志
通过features:list 来查看所有的特性,并从而可以分析当前特性是否安装
若没有安装 可以通过 features:install来安装,比如:features:install webconsole
4. 与Camel 集成
先查看是否存在camel相关features,没有则按照相应的bundles
接下来我们做一个例子:分别设置两个目录input和output,在input放入文件后则被传送到output中。而这个过程就是通过serviceMix调用camel router来完成
- Blueprint xml file
下面是一个配置的router文件描述,你可以通过自己写文件,当然最好还是用可视化工具,后面我们再花时间聊聊这东东,这个时候就绕不开Enterprise Integration pattern 又是标准,老外厉害。
我们这里直接先贴上文件:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint
xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="file:bgao/input" />
<log message="happy day!!!" />
<to uri="file:bgao/output" />
</route>
</camelContext>
</blueprint>
并命名为firstCamelRouter.xml
- 配置到serviceMix
将文件放入到serviceMix的deploy中,这个时候后再serviceMix目录下发现bgao的目录并下面有个input文件夹,这时候如果在input文件夹放入一个文件,这bgao目录下会出现output目录并且将input目录的文件移到output上。通过log:display 可以查看到当前这个动作的日志。
通过karaf@root> osgi:list | grep xml
[ 43] [Active ] [GracePeriod ] [ ] [ 60] activemq-broker.xml (0.0.0
)
[ 129] [Active ] [ ] [ ] [ 60] Apache ServiceMix :: Bundl
es :: xmlsec (1.4.5.1)
[ 138] [Active ] [ ] [ ] [ 60] Apache ServiceMix :: Bundl
es :: xmlbeans (2.4.0.4)
[ 142] [Active ] [ ] [ ] [ 60] Apache ServiceMix :: Bundl
es :: xmlresolver (1.2.0.3)
[ 163] [Active ] [Created ] [ ] [ 60] firstCamelRouter.xml (0.0.
0)
得到当前ID为163;通过osgi:stop 163或者 osgi:start 163 来启动或者关闭当前bundle
5. 与ActiveMQ集成
先查看是否存在camel相关features, 没有则按照相应的bundles
我们做一个例子:
对两个文件进行文件移动,同时对MQ队列产生一个event 消息并捕获消息打出到日志。
第一个文件:firstMq.xml
<?xml version="1.0" encoding="UTF-8"?>
<blueprint
xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="file:bgao/mq/input" />
<to uri="file:bgao/mq/output" />
<setBody>
<simple>
File Move Event (${file:name},${date:now:hh:MM:ss.SSS})
</simple>
</setBody>
<to uri="activemq://event" />
</route>
</camelContext>
</blueprint>
这时候,文件已经移到output,现在是event message都在队列里面,但还没有人去处理他,现在通过secondeMq里处理她。
设置第二个文件 secondMq.xml 放入deloy文件夹中
<?xml version="1.0" encoding="UTF-8"?>
<blueprint
xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="activemq://event" />
<from uri="file:bgao/mq/input" />
<to uri="log:events" />
</route>
</camelContext>
</blueprint>
启动当前这个bundle 然后打日志就发现有
2012-06-11 16:01:43,751 | INFO | sConsumer[event] | events
| ? ? | 91 - org.apache.camel.camel-core

6. Webconsole
通过安装features:install webconsole后,可以通过访问http://localhost:8181/system/console
用户名:smx
密码:smx
当前webconsole 是karaf框架提供的一个web页面系统。
从weblogic 10.3.4开始支持maven deploy部署
步骤如下:
1.构建weblogic-maven-plugin jar
在D:\oracle\Middleware\wlserver_12.1\server\lib
找到 WebLogic JarBuilder Tool (wljarbuilder),执行:
java -jar wljarbuilder.jar -profile weblogic-maven-plugin
2.将weblogic-maven-plugin jar中的pom.xml 解压出放入到在
D:\oracle\Middleware\wlserver_12.1\server\lib
可以使用命令:
jar xvf D:/oracle/Middleware/wlserver_12.1/server/lib/weblogic-maven-plugin.jar
META-INF/maven/com.oracle.weblogic/weblogic-maven-plugin/pom.xml
cp D:/oracle/Middleware/wlserver_12.1/server/lib/META-INF/maven/com.oracle.weblogic/
weblogic-maven-plugin/pom.xml D:/oracle/Middleware/wlserver_12.1/server/lib
3.安装插件:
一种将weblogic-maven-plugin.jar 和pom.xml上传到nexus的第三方库中
另一种执行mvn install:install-file -Dfile=weblogic-maven-plugin.jar -DpomFile=pom.xml
进行安装。这个时候在你的本地仓库能到找.m2\repository\com\oracle\weblogic
4.在当前需要上传的应用的pom中配置weblogic的相关配置
比如:
<!--auto deploy war to weblogic by maven-->
<plugin>
<groupId>com.oracle.weblogic</groupId>
<artifactId>weblogic-maven-plugin</artifactId>
<version>10.3.6.0</version>
<configuration>
<adminurl>t3://192.168.2.141:9001</adminurl>
<user>weblogic</user>
<password>123456</password>
<upload>true</upload>
<action>deploy</action>
<remote>false</remote>
<verbose>true</verbose>
<source>target/demo.war</source>
<name>demo</name>
</configuration>
<!--
<executions>
<execution>
<phase>install</phase>
<goals>
<goal>deploy</goal>
</goals>
</execution>
</executions>
-->
</plugin>
<!-- end-->
先打包生成demo.war,然后执行>mvn com.oracle.weblogic:weblogic-maven-plugin:deploy
主要官方提供的命令是:mvn weblogic:deploy; 其实你敲这个命令你会发现,他用的不是oracle的plugin
而是用的 org.codehaus.mojo的
此外如果需要提前命令,可以用help来查看,查看结果:
『
---
The following are the goals available currently in Maven
deploy
list-apps
redeploy
start-app
stop-app
undeploy
update-app
』
执行成功后,回到weblogic的console台,你能发现你的war包,同时可以访问看是否部署成功。
如果想直接一个命令部署怎么办? 直接在mvn命令后面加上package
mvn package com.oracle.weblogic:weblogic-maven-plugin:deploy
但是他报错:
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal com.oracle.weblogic:weblogic-maven-plugin:10.3.6.
0:deploy (default-cli) on project ep-easyui-webapp: weblogic.deploy.api.tools.de
ployer.DeployerException: Java heap space -> [Help 1]
[ERROR]
原因是jdk 内存不够
为mvn设置内存,在maven.bat上加上
set MAVEN_OPTS=-Xdebug -Xnoagent -Xms256m -Xmx512m -Djava.compiler=NONE
这句话本身是@rem有。
然后直接
mvn package com.oracle.weblogic:weblogic-maven-plugin:deploy
就是能成功。
参考文献:
http://docs.oracle.com/cd/E24329_01/web.1211/e24443/maven_deployer.htm
主要10.3以后好像才有这个支持,另外12g和11g也有区别。
调试maven时候,报错
[INFO] ------------------------------------------------------------------------

我在pom.xml 文件中添加
<dependency>

</dependency>
仍然抱这个错,解决方法
1) Manually install this artifact into your local repo cache
2) Add an excludes and a corresponding dependency so you get a proper artifact
3) Stop depending on outdated Hibernate artifacts, I'd suggest
upgrading to this one:
http://repo2.maven.org/maven2/org/hibernate/hibernate-annotations/3.4.0.GA/
改成<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.4.0.GA</version>
</dependency>
同时把
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>ejb</artifactId>
<version>3.0-public_review</version>
</dependency>
去掉
通过mvn调用ant 的build.xml 文件
Mvn 命令出错,出错信息:

而直接 echo %Java_Home%
得到:
D:\Java\jdk1.6.0_01
再直接mvn –version:
Apache Maven 3.0.4 (r1232337; 2012-01-17 16:44:56+0800)
Maven home: D:\Java\apache-maven-3.0.4
Java version: 1.6.0_01, vendor: Sun Microsystems Inc.
Java home: D:\Java\jdk1.6.0_01\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows vista", version: "6.1", arch: "x86", family: "windows"
发现 的确 mvn 指向的java home 是D:\Java\jdk1.6.0_01\jre
解决方法:
在build.xml 文件中添加
<property name="build.compiler" value="extJavac"/>
