dwr的学习笔记一
由于项目中使用到了dwr，所以让我开始慢慢去关注它，以前只是听说过但并没觉得有多好，它的安全性一直是我怀疑的地方，但是今天看了一下dwr文档，感觉还是有很多地方可以值得学习的！
说说项目中常用dwr的时候，其返回值和参数的一些配置和运用。

1：没有返回值也没有参数的情况下

   function btClick(){        DwrTest.getName();    }

  <create creator="new" javascript="DwrTest">      <param  name="class"    value="com.mochasoft.ps.flfx.postriskmanager.action.DwrTest"></param>  </create>

         public void getName(){  System.out.println("名字：哈哈哈哈!!!");}

2：返回值属于基本数据类型或者String，Integer等

  function btClick(){        DwrTest.getName(callBack);   }      function callBack(data){     alert("name:"+data);   }

<create creator="new" javascript="DwrTest">  <param  name="class" value="com.mochasoft.ps.flfx.postriskmanager.action.DwrTest"></param>  </create>

public String getName(){String name = "哈哈哈";return name;}

3：返回集合Map、List、Set

function btClick(){        DwrTest.getName(callBack);   }      function callBack(data){      for(var index in data){        alert(data[index]);      }   }

<create creator="new" javascript="DwrTest">  <param  name="class" value="com.mochasoft.ps.flfx.postriskmanager.action.DwrTest"></param>  </create>

public Map getName(){Map names = new HashMap();String name1 = "哈哈！";String name2 ="哈哈哈!";String name3 = "哈哈！";names.put("name1",name1);names.put("name2",name2);names.put("name3",name3);return  names;}

4:返回一个bean对象

function btClick(){        DwrTest.getName("哈哈哈","男不男女不女",callBack);   }      function callBack(data){      alert("名字:"+data.name);      alert("性别:"+data.sex);   }

<create creator="new" javascript="DwrTest">  <param  name="class" value="com.mochasoft.ps.flfx.postriskmanager.action.DwrTest"></param>  </create>  <convert converter="bean" match="com.mochasoft.ps.flfx.postriskmanager.action.Man">  </convert>

public Man getName(String name,String sex){Man man = new Man();man.setName(name);man.setSex(sex);return man;}

5：参数为bean

function btClick(){        var man = {name:"哈哈哈",sex:"男"};        DwrTest.getName(man,callBack);   }      function callBack(data){    alert(data);   }

<create creator="new" javascript="DwrTest">  <param  name="class" value="com.mochasoft.ps.flfx.postriskmanager.action.DwrTest"></param>  </create>  <convert converter="bean" match="com.mochasoft.ps.flfx.postriskmanager.action.Man">  </convert>

public String getName(Man man){String strRet = man.getName()+"\t"+man.getSex();return strRet;}

6：参数为集合类型（由于本人使用的是JDK4，所以没有测试以下功能，只有JDK5才支持泛型）

function btClick(){        var man = [                     {name:"哈哈哈",sex:"男"},                     {name:"哈哈哈2",sex:"不男不女"}];        DwrTest.getName(man,callBack);   }      function callBack(data){    alert(data);   }

<create creator="new" javascript="DwrTest">  <param  name="class" value="com.mochasoft.ps.flfx.postriskmanager.action.DwrTest"></param>  </create>  <convert converter="bean" match="com.mochasoft.ps.flfx.postriskmanager.action.Man">  </convert>    <signatures>      <![CDATA[    import java.util.List;  import com.mochasoft.ps.flfx.postriskmanager.action.Man;  import com.mochasoft.ps.flfx.postriskmanager.action.DwrTest  DwrTest.getName(List<Man> nos);      ]]>    </signatures>

public String getName(List<Man> list) {String strRet = "";for (int i = 0; i < list.size(); i++) {Man man = (Man) list.get(i);strRet += man.getName() + "\t" + man.getSex();}return strRet;}
