Flex与SSH集成
，下载blazeds_bin_3---.zip 包，将其解压 取下blazeds.war包 更改为blazeds.rar ,并解压
 将上一步解压的web-inf/lib/下的包复制到工程的lib下
，将flex文件夹 复制到工程的web-inf下
 将classes下的文件复制到工程的src下
5在web.xml中加入
 
<!-- flex -->
 <servlet>
    <servlet-name>flex</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
         <param-name>contextConfigLocation</param-name>
           <param-value>/WEB-INF/classes/flex-application-config.xml</param-value>
    </init-param>
    <load-on-startup></load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>flex</servlet-name>
    <url-pattern>/ssh/*</url-pattern>
</servlet-mapping>
<!-- end flex -->
6，在src下建一个flex-application-config.xml文件
加入
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:flex="http://www.springframework.org/schema/flex"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/flex
http://www.springframework.org/schema/flex/spring-flex-1.0.xsd">
<flex:message-broker/>
<!— 下面是表示 在spring配置文件中配置的bean-->
<flex:remoting-destination ref="flowServer"/>
</beans>
以下内容
6,加入flex与spring所依赖的包

7 编写 java 类
 
1>    编写类体DeptNode.class
 
package com.svse.entity.bean;
 
import java.util.ArrayList;
import java.util.List;
/***
*  注: 此类可以不用和Flex映射 ,因为在Flex端,我们不用把Object对象强转为此对象
**/
public class DeptNode {
 
    private int id;
    private String name;
    private DeptNode parent;
 
    private List<DeptNode> children = null;
 
    public DeptNode(){}
    public DeptNode(int id ,String name){
       this.id = id;
       this.name = name;
    }
    /*************get and set 省略****************/
 
}
>    编写接口IflowServer.class
package com.svse.server;
 
import java.util.List;
import com.svse.entity.bean.DeptNode;
 
public interface IFlowServer {
              //得到部门
       List<DeptNode> getDeparts(int deptId);
}
 
>    编写实现类
package com.svse.server.impl;
 
import java.util.List;
 
import com.svse.entity.bean.DeptNode;
import com.svse.server.IFlowServer;
 
public class FlowServer implements IFlowServer {
 
    //得到部门
    public List<DeptNode> getDeparts(int deptId){
       List<DeptNode> list = new ArrayList<DeptNode>();
       DeptNode node = new DeptNode();
       node.setId();
       node.setName("父节点11");
       node.setChildren(this.getChild(, "aa"));
 
       list.add(node);
 
       DeptNode node2= new DeptNode();
       node2.setId();
       node2.setName("父节点22");
       node2.setChildren(this.getChild(, "bb"));
 
       list.add(node2);
 
       return list;
    }
 
    private List<DeptNode> getChild(int count,String name){
       List<DeptNode> list = new ArrayList<DeptNode>();
       for(int i = ; i < count; i++){
           DeptNode node3 = new DeptNode();
           node3.setId(i);
           node3.setName(name+""+i);
           list.add(node3);
       }
       return list;
    }
 
    }
}
 
 在spring中注入
<bean id="flowServer" class="com.svse.server.impl.FlowServer"/>
注：此处的Id,就是在flex-application-config.xml中的
<flex:remoting-destination ref="flowServer"/>配置的ref值
 
 编写flex代码
