学习就从官方的测试开始,但不知道怎么回事官方的测试有问题,这我就把我配置的简单junit环境共享给大家把! 1.下载 hibernate-annotations-3.4.0.GA 并解压 ,cd 到解压后目录下 2. $> ant junit (天知道,怎么官方出的东西测试不能通过!!) 不要急,我们来看错误 (错误提示有删减) 错误-1:$>build.xml:95: ./jdbc not found. 解决办法-1: $>mkdir ./jdbc 3. $> ant junit 错误-2: ./build.xml:124: The following error occurred while executing this line: ./build.xml:126: The following error occurred while executing this line: ./common-build.xml:349: .\src\filters\hsqldb.filter as it doesn't exist. 解决办法-2: $> mkdir ./src/filters ; $> echo "" > ./src/filters/hsqldb.filter; 4. $>ant junit 错误-3: ./build.xml:124: The following error occurred while executing this line: ./build.xml:126: The following error occurred while executing this line: ./common-build.xml:351: .\src\test-resources not found. $> mkdir ./src/test-resources ; 5. $> ant junit 错误-4:没有ant 错误了!,但测试都为错误,那我们就看看 第一个测试吧,找下原因! test-resources: [mkdir] Created dir: hibernate-anntations-3.4.0.GA\build\test-reports\hsqldb [echo] Running against db: hsqldb [junit] Running org.hibernate.test.annotations.ConfigurationTest [junit] Tests run: 7, Failures: 0, Errors: 6, Time elapsed: 1.218 sec ............. $> find . -name "ConfigurationTest.java" #pwd /hibernate-anntations-3.4.0.GA ./test/org/hibernate/test/annotations/configuration/ConfigurationTest.java ./test/org/hibernate/test/annotations/ConfigurationTest.java 根据路径 org.hibernate.test.annotations.ConfigurationTest gvim ./test/org/hibernate/test/annotations/ConfigurationTest.java 发现第20行: cfg.configure( "org/hibernate/test/annotations/hibernate.cfg.xml" ); 感觉应该没有配置 jdbc gvim ./test/org/hibernate/test/annotations/hibernate.cfg.xml #果然 没配置 我这就放个我的简单配置上来(使用 hbm hsqldb 内存数据库测 试 ): <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property> <property name="connection.driver_class">org.hsqldb.jdbcDriver</property> <property name="connection.url">jdbc:hsqldb:mem:hbn_ann</property> <property name="connection.username">sa</property> <property name="connection.password"></property> <mapping resource="org/hibernate/test/annotations/Boat.hbm.xml"/> <mapping package="org.hibernate.test.annotations"/> <mapping class="org.hibernate.test.annotations.Plane"/> </session-factory> </hibernate-configuration> 我这就是要hsqldb吧,既然上面错误1有 jdbc 文件夹,那就是放 jdbc jar 的地方 $> cp ../hsqldb.jar ./jdbc 6. $> ant junit 呵呵 测试 第一个正确了 ! (目前配置后,测试环境并不是全部都正确,比如第2个测试) 其他测试错误日志在 .\build\test-reports\hsqldb ... 比如第2个错误 异常部分 org.hibernate.HibernateException: The dialect was not set. Set the property hibernate.dialect. at org.hibernate.dialect.Dialect.instantiateDialect(Dialect.java:256) at org.hibernate.dialect.Dialect.getDialect(Dialect.java:234) ........ 大家一边学习,一边配置测试 环境吧。 错误日记 都会在 build\test-reports\hsqldb下

javascript 学习
javascript 大体上可分为3个不同部分组成: 核心(ECMAscript),文本对象(DOM),浏览器对象(BOM)
-
核心(ECMAscript): 关键字,语句,运算符,对象
-
文本对象(DOM):DOM将把整个页面规划成由节点层级构成的文档.
-
解析遵循 W3C html dom 标准:
-
W3C dom 参考特别关注 DOM Node 说明
-
BOM 浏览器对象. cookie,弹出新浏览器,浏览器设置大小
核心(ECMAscript)Global 内置对象;
方法: parseInt(),isNan(),encodeURI()...等都为此对象方法 特别注意 eval();动态语言的象征 比如:eval("alert('hi')"); 但这个方法很邪恶(安全方面)
文本对象(DOM)说明:
<bookstore> <book category="cooking"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> </bookstore> | | |
1. ECMAscript基础 $ 变量弱类型 ; 匈牙利类型标示 : var iOuouValue=100;
$ 结束行分号有无都可以; 但再 onsubmit="javascript:function();return false;" $ 关键字 ; 提别注意
"constructor" bean.constructor
//print bean function(){ ....
}
"typeof" var test=1; alert(typeof testX); //output "undefined" "NaN" - not a number -> isNan("blue"); //output "true" ->isNan("123"); //output "false" $ 对象; var o = new Object(); var a = {}
这里特别说明下 我们普通写的 一个 function 就是一个 object 这 var a = {name:"刘凯毅"} 等同与 var a = function(){this.name="刘凯毅"}; 来个 {name:"test",pass:"123456",addr:"bj"} //这是什么 ?! json
当 var str = '{name:"test",pass:"123456",addr:"bj"}' var objectBean = eval(str); //这里就是 对象 objectBea.name 使用了
域概念: <SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
sColor = 'red';
sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello World!
alert(sColor); //red
</SCRIPT> | <SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
var sColor = 'red';
sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello World!
alert(sColor); // 什么都没有
</SCRIPT>
| <SCRIPT type=text/javascript>
var sMessage = 'Hello';
function setSomething() {
var sColor = 'red';
var sMessage = 'Hello World!';
}
setSomething();
alert(sMessage); //Hello
alert(sColor); // 什么都没有
</SCRIPT>
|
为面向对象做基础:object prototype 类型的对象应用。参考 // 最简单的 继承
Object.prototype.inObj = 1;
function A()
{
this.inA = 2;
}
A.prototype.inAProto = 3;
B.prototype = new A; // Hook up A into B's prototype chain
B.prototype.constructor = B;
function B()
{
this.inB = 4;
}
B.prototype.inBProto = 5;
x = new B;
document.write(x.inObj + ', ' + x.inA + ', ' + x.inAProto + ', ' + x.inB + ', ' + x.inBProto);
//1, 2, 3, 4, 5
//增加点信心 http://www.json.org/json.js
Object.prototype.toJSONString = function (filter) { return JSON.stringify(this, filter); }; 后我们就可以使用 bean.toJSONString()不是吗?
|
$ arguments ; function getFun(){alert(arguments.length);} ;
getFun("xx") //output 1 getFun("xx",23) //output 2
$ 语句 ;特殊说明下 for for(var i=0i<iCount;i++) 或 for( attr in object ) ;
如果无聊 你可以 for( sProp in window ){alert(sProp+"你丫点啊!");} //看看 javascript 的反射
面向对象: var bean = new Bean();
1.工厂方法 function getAttr(){ alert(this.attr)
} function Bean(tattr){ var bean = new Object; bean.attr = tattr; bean.getAttr = getAttr; return bean ;
} 根本就是山寨版 面向对象
2.构造 function Bean(tattr){ this.attr = tattr ; bean.getAttr = function(){ alert(this.attr); } } 其上 2 总 再Bean 对象创建时,方法会 “重复生成函数”!
3.原型模式 function Bean(){} Bean.prototype.attr = ""; Bean.prototype.getAttr=function(){alert(this.attr);}
解决 “重复生成函数” 问题,但新的问题 Bean.prototype.getArray = new Array();
其 new 对象 bean1 和 bean2 都会共享 new Array 空间(是我们不想看到的)
4.混合 模型 :) 哈哈 function Bean(){ this.attr= "";
this.getArray=new Array;
} Bean.prototype.getAttr=function(){alert(this.attr);}
5.动态原型 (注意下面开始,就是真正的面向对象!!!) function Bean(){ this.attr= "";
this.getArray=new Array; //classload 加载 时
if(typeof Bean._initialized == "undefined" ){ Bean.prototype.getAttr=function(){alert(this.attr);};
Bean._initialized= true ; }
}
/****************************************************************/
对象继承
1.对象冒充!!(可支持多继承,山寨很强大)
function classA(sstr){ this.color = sstr ; this.sayColor = function(){ alert(this.color);
};
} function classC(){}
function classB(){ this.newMethod =ClassA ; this.newMethod(); delete this.newMethod ;
this.newMethod =ClassC ; this.newMethod(); delete this.newMethod ; this.arrt = "google";
}
2.call() apply() 也山寨, function classA(sstr){ this.color = sstr ; this.sayColor = function(str){ alert(str+this.color);
};
}
function classB(){ // this.newMethod =ClassA ; // this.newMethod(); // delete this.newMethod ; classA.call(this,"red"); //classA.apply(this,new Array("red"))
this.arrt = "baidu";
} 3.正统的继承 原型链 (但不支持多继承) function classA(){this.oo="test";} classA.prototype.color = "red"; function classB(){} classB.prototype = new classA ; classB.prototype.sayName = function(){ alert( this.color ); } var bb = new classB ; bb.sayName(); // output red alert(bb.oo); // output test
alert( bb instanceof classA); //output true alert( bb instanceof classB); //output true4.如果你要多继承!!并且还支持 instanceof 混合方式: function classA(){} function classB(){} function classC(){ classA.call(this); classC.call(this); } classC.prototype = new classA ;//注意 这 instanceof 只能对 A有用

Python is a dynamic object-oriented programming language that can be used for many kinds of software development.
It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days. offers 提出 integration 综合 extensive 宽广 standard libraries 标准库
Many Python programmers report substantial productivity gains and feel the language encourages the development of higher quality, more maintainable code. report 宣告 substantial 实质 productivity 生产力
