Flex与SSH集成  2010-06-26 11:00:36|  分类： flex |举报|字号 订阅Flex与SSH集成1，下载blazeds_bin_3-0-0-544.zip 包，将其解压 取下blazeds.war包 更改为blazeds.rar ,并解压2 将上一步解压的web-inf/lib/下的包复制到工程的lib下3，将flex文件夹 复制到工程的web-inf下4 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>1</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Flex与SSH集成 - 花落谁家 - zhangcb666的博客 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****************/   }2>    编写接口IflowServer.classpackage 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);}  3>    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(00);       node.setName("父节点11");       node.setChildren(this.getChild(3, "aa"));             list.add(node);             DeptNode node2= new DeptNode();       node2.setId(11);       node2.setName("父节点22");       node2.setChildren(this.getChild(5, "bb"));             list.add(node2);             return list;    }       private List<DeptNode> getChild(int count,String name){       List<DeptNode> list = new ArrayList<DeptNode>();       for(int i = 0; i < count; i++){           DeptNode node3 = new DeptNode();           node3.setId(i);           node3.setName(name+""+i);           list.add(node3);       }       return list;    }     }} 8 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  9 编写flex代码 <?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()">    <mx:Script>       <![CDATA[           import mx.rpc.remoting.mxml.RemoteObject;
