这几天实现了一个向远程Jboss服务器中部署文件的程序，是采用Jboss 的 JMX 远程调用方法来实现的，方法比较简单，略微修改就可以把文件传送到远程启动了Jboss服务器的机器上，希望与大家分享，此处贴上了全部实例代码，配置好后即可运行。
实现步骤如下：
1、下载安装Jboss服务器
2、新建立java项目，引入jboss安装目录 server\default\lib 中的 jboss.jar 和 jmx-adaptor-plugin.jar 包到classpath中
3、建立 RMIAdaptorHelper.java 类，用于处理远程调用，代码如下：
package com.sample.jmxagent.jboss;
import java.io.Serializable;
import java.util.Properties;
import javax.management.ObjectName;
import javax.naming.CommunicationException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import org.jboss.jmx.adaptor.rmi.RMIAdaptor;
public class RMIAdaptorHelper
{
private String _rmiHost = "127.0.0.1";
private int _rmiPort = 1099;
private int _timeout = 2000; // ms
private RMIAdaptor _server;
public RMIAdaptorHelper(String rmiHost, int rmiPort, int timeout)
throws CommunicationException, NamingException
{
this._rmiHost = rmiHost;
this._rmiPort = rmiPort;
this._timeout = timeout;
}
/**
* 远程调用 MBEAN
*/
public Object invoke(RmiInvokeObject rmido) throws Exception
{
ObjectName name = new ObjectName(rmido.getJndiname());
return _server.invoke(name, rmido.getMethodname(), rmido
.getMethodArgs(), rmido.getMethodArgsType());
}
/**
* 连接 Jboss rmi 服务器
*/
public void connect() throws NamingException, CommunicationException
{
Properties prop = System.getProperties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
prop.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
prop.put(Context.PROVIDER_URL, "jnp://" + _rmiHost + ":" + _rmiPort);
prop.put("jnp.discoveryTimeout", String.valueOf(_timeout));
InitialContext ic = new InitialContext(prop);
if (_server != null)
{
System.out.println("RMIAdaptorHelper not null");
_server = null;
}
Object o = ic.lookup("jmx/rmi/RMIAdaptor");
_server = (RMIAdaptor) o;
}
/**
* 远程调用的对象类
*/
public class RmiInvokeObject implements Serializable
{
private String jndiname;
private String methodname;
private Object[] methodArgs;
private String[] methodArgsType;
public String getJndiname()
{
return jndiname;
}
public void setJndiname(String mbeanName)
{
this.jndiname = mbeanName;
}
public Object[] getMethodArgs()
{
return methodArgs;
}
public void setMethodArgs(Object[] methodArgs)
{
this.methodArgs = methodArgs;
}
public String[] getMethodArgsType()
{
return methodArgsType;
}
public void setMethodArgsType(String[] methodArgsType)
{
this.methodArgsType = methodArgsType;
}
public String getMethodname()
{
return methodname;
}
public void setMethodname(String methodname)
{
this.methodname = methodname;
}
}
}
4、建立 FileObject.java 类，用于存储所要传输的文件内容，代码如下：
package com.sample.upload.mbean;
import java.io.Serializable;
public class FileObject implements Serializable
{
public byte[] fileContent;
}
5、建立 FileUploadMBean.java 接口，用于 Jboss 调用，代码如下：
package com.sample.upload.mbean;
public interface FileUploadMBean
{
public boolean uploadFile(String fileName, FileObject fo) throws Exception;
}
6、建立 FileUpload.java 类，用于实现FileUploadMBean 接口，代码如下：
package com.sample.upload.mbean;
import java.io.File;
import java.io.FileOutputStream;
import java.net.URI;
public class FileUpload implements FileUploadMBean
{
public static final String JBOSS_SERVER_BASE_URL = "jboss.server.base.url";
public static final String JBOSS_SERVER_NAME = "jboss.server.name";
public static final String JBOSS_SERVER_PATH = System.getProperty(JBOSS_SERVER_BASE_URL)+ System.getProperty(JBOSS_SERVER_NAME);
public static final String NODE_ADAPTOR_PATH = JBOSS_SERVER_PATH + "/";
private FileOutputStream fos = null;
private File f = null;
public boolean uploadFile(String fileName, FileObject fo) throws Exception
{
boolean returnValue = false;
try
{
// 在 Jboss 的 server\default 目录下新建立文件
f = new File(new URI( NODE_ADAPTOR_PATH + fileName));
f.createNewFile();
fos = new FileOutputStream(f);
fos.write(fo.fileContent);
returnValue = true;
}
catch (Exception ex)
{
ex.printStackTrace();
throw ex;
}
finally
{
if (fos != null)
{
try
{
fos.close();
}
catch (Exception ee)
{
ee.printStackTrace();
}
}
}
return returnValue;
}
}
7、建立 TestFileUpload.java 类，用于测试文件上传，代码如下：
package com.sample.upload.test;
import java.io.File;
import java.io.FileInputStream;
import com.sample.jmxagent.jboss.RMIAdaptorHelper;
import com.sample.upload.mbean.FileObject;
public class TestFileUpload
{
private static RMIAdaptorHelper rah;
/**
* 向 Jboss 上传指定目录的文件
*/
public static void uploadFile(String fileName) throws Exception
{
File f = new File(fileName);
byte[] b = new byte[(int) f.length()];
FileInputStream fis = new FileInputStream(f);
try
{
fis.read(b);
FileObject fo = new FileObject();
fo.fileContent = b;
RMIAdaptorHelper.RmiInvokeObject rmido = rah.new RmiInvokeObject();
rmido.setJndiname("com.sample.remotedeploy.mbean.control:service=FileUpload");
rmido.setMethodname("uploadFile");
rmido.setMethodArgsType(new String[]{"java.lang.String",
"com.sample.upload.mbean.FileObject"});
rmido.setMethodArgs(new Object[]{f.getName(), fo});
rah.invoke(rmido);
}
catch (Exception ex)
{
ex.printStackTrace();
}
finally
{
if (fis != null)
{
try
{
fis.close();
}
catch (Exception ee)
{
ee.printStackTrace();
}
}
}
}
public static void main(String[] args)
{
try
{
rah = new RMIAdaptorHelper("127.0.0.1", 1099, 5000);
// 连接 Jboss rmi 服务器
rah.connect();
// 向 Jboss 上传指定目录的文件
uploadFile(args[0]);
}
catch (Exception e)
{
e.printStackTrace();
}
System.exit(0);
}
}
8、在Jboss的安装目录server\default\deploy下建立 com.sample.sar\META-INF目录，并在其下建立两个文件jboss-service.xml 和 MANIFEST.MF ，用于把方法部署到Jboss中，jboss-service.xml 代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<server>
<mbean
code="com.sample.upload.mbean.FileUpload"
name="com.sample.remotedeploy.mbean.control:service=FileUpload">
<depends>jboss.system:service=Logging,type=Log4jService</depends>
<!-- jboss.rmi -->
<depends>jboss.rmi:type=RMIClassLoader</depends>
<!-- jboss jmx -->
<depends>jboss.jmx:name=Invoker,type=adaptor</depends>
<depends>jboss.jmx:name=Invoker,protocol=jrmp,service=proxyFactory,type=adaptor</depends>
<depends>jboss.jmx:alias=jmx/rmi/RMIAdaptor</depends>
<!-- jboss.security -->
<depends>jboss.security:service=JaasSecurityManager</depends>
<depends>jboss.security:service=SecurityConfig</depends>
<depends>jboss.security:service=XMLLoginConfig</depends>
<!-- jboss -->
<depends>jboss:service=ClientUserTransaction</depends>
<depends>jboss:service=Naming</depends>
<depends>jboss:service=ClientUserTransaction</depends>
<depends>jboss:service=TransactionManager</depends>
<depends>jboss:service=UUIDKeyGeneratorFactory</depends>
<depends>jboss:service=invoker,type=jrmp</depends>
<depends>jboss:service=proxyFactory,target=ClientUserTransaction</depends>
<depends>jboss:service=proxyFactory,target=ClientUserTransactionFactory</depends>
</mbean>
</server>
9、MANIFEST.MF 代码如下：
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.2
Created-By: 1.4.2_05-b04 (Sun Microsystems Inc.)
10、此时把所有Java编译后的class文件打包成 com.sample.jar 并拷贝到Jboss安装目录 server\default\lib 下，启动Jboss（即运行bin目录下的run.bat），再运行 TestFileUpload.java 程序进行测试（带入参数为要上传文件及完整目录名，如 java com.sample.upload.test.TestFileUpload E:\test.txt 注意引入-Classpath变量），则文件会上传到Jboss的server\default目录中。
希望大家有所收获。
