FLEX与WEB项目简单HTTPSERVICE通讯

一.创建WEB工程，应用STRUTS（本例只作简单测试未与数据库连接）

处理类1：

package action;
import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionServlet;
import bussness.UserInfoBo;
import entity.UserInfoForm;
public final class LogonAction extends Action {
 
  public ActionForward execute(ActionMapping mapping,
         ActionForm form,
         HttpServletRequest request,
         HttpServletResponse response)
         throws IOException, ServletException {
    UserInfoForm userInfoForm = (UserInfoForm) form;        
    //从web层获得用户名和口令
    String username = userInfoForm.getUsername().trim();
    String password = userInfoForm.getPassword1().trim();
    //声明错误集对象
    ActionErrors errors = new ActionErrors();
    //校验输入
    if(username.equals("")){
      ActionError error=new ActionError("error.missing.username");
      errors.add(ActionErrors.GLOBAL_ERROR,error);
    }
    if(password.equals("")){
      ActionError error=new ActionError("error.missing.password");
      errors.add(ActionErrors.GLOBAL_ERROR,error);
    }
    PrintWriter out = response.getWriter();
    //调用业务逻辑
    if(errors.size()==0){
      String validated = "";
      try{
        UserInfoBo userInfoBo=new UserInfoBo();
        validated =userInfoBo.validatePwd(username,password);
        if(validated.equals("match")){
          //一切正常就保存用户信息并转向成功的页面 
          HttpSession session = request.getSession();
          session.setAttribute("userInfoForm", form);         
          out.print("aaaaa");
//          return mapping.findForward("success");
          return mapping.findForward("success2");
        }
      }
     
      catch(Throwable e){
        //处理可能出现的错误
        e.printStackTrace();
        ActionError error=new ActionError(e.getMessage());
        errors.add(ActionErrors.GLOBAL_ERROR,error);
      }
    } 
    //如出错就转向输入页面，并显示相应的错误信息
    saveErrors(request, errors);
    out.print("bbbbb");
//    return new ActionForward(mapping.getInput());  
    return mapping.findForward("success2");
  }
}

 

处理类2：

package bussness;
 
import entity.UserInfoForm;
 
public class UserInfoBo {
 
  public UserInfoBo(){
   
  }     
 
  public String validatePwd(String username,String password){
        
    String validateResult="";
   
    if(username.equals("test")&&password.equals("test")){
      validateResult="match";
      System.out.println("登录成功： "+username);
    }
    else{
     System.out.println("登录失败： "+username);
      throw new RuntimeException("error.noMatch");
    }           
   
    return validateResult;  
   
  }
}

 

处理类3：

# Resources for parameter 'com.yourcompany.struts.ApplicationResources'
# Project testFlex
#Application Resource for the logon.jsp
logon.jsp.title=The logon page
logon.jsp.page.heading=Welcome World!
logon.jsp.prompt.username=Username:
logon.jsp.prompt.password=Password:
logon.jsp.prompt.submit=Submit
logon.jsp.prompt.reset=Reset
 
#Application Resource for the main.jsp
main.jsp.title=The main page
main.jsp.welcome=Welcome:

#Application Resource for the LogonAction.java
error.missing.username=<li><font color="red">missing username</font></li>
error.missing.password=<li><font color="red">missing password</font></li>

#Application Resource for the UserInfoBo.java
error.noMatch=<li><font color="red">no matched user</font></li>
 

 处理类4：

package entity;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;
 
public class UserInfoForm extends ActionForm{
 
  private String username;
  private String password1;
 
 
  public String getUsername() {
    return (this.username);
  }
  public void setUsername(String username) {
    this.username = username;
  }
 
  public String getPassword1() {
    return (this.password1);
  }
  public void setPassword1(String password1) {
    this.password1 = password1;
  }
}

 

配置STRUTS.XML：

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
  <data-sources />
  <form-beans>
    <form-bean name="userInfoForm" type="entity.UserInfoForm" />
  </form-beans>

   
  <global-exceptions />
  <global-forwards />
  <action-mappings>
    <action input="/logon.jsp" name="userInfoForm" path="/logonAction" scope="session"
         type="action.LogonAction" validate="false">
      <forward name="success" path="/main.jsp" />
      <forward name="success2" path="/MyJsp.jsp"/>    
    </action>
  </action-mappings>
  <message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>

 

配置WEB.XML：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts-config.xml</param-value>
    </init-param>
    <init-param>
      <param-name>debug</param-name>
      <param-value>3</param-value>
    </init-param>
    <init-param>
      <param-name>detail</param-name>
      <param-value>3</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

 

配置JSP：（MyJsp.jsp）

<%@page import="java.util.List"%>
<%
response.setContentType("text/xml");
out.println("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
out.println("<userinfo>");
 
        out.println("<user userId=\""+3123+"\">");       
        out.println("<username>"+42314+"</username>");
        out.println("<userpwd>"+3123+"</userpwd>");
        out.println("<useremail>"+4231+"</useremail>");
        out.println("<userage>"+2+"</userage>");
        out.println("<regdate>"+4231+"</regdate>");
        out.println("</user>");
 
out.println("</userinfo>");
%>

二.FLEX端处理

FLEX通过HTTPSERVICE与WEB项目通迅代码如下：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
    layout="absolute"
    backgroundColor="#FFFFFF"
    backgroundAlpha="0" horizontalCenter="true" >
   
 <mx:HTTPService id="info" url="http://127.0.0.1:8080/testFlex/logonAction.do">
  <mx:request>
   <username>
       {username.text}
   </username>   
   <password1>
       {password.text}
   </password1>
  </mx:request>
 </mx:HTTPService>   
 
 <mx:TitleWindow id ="loginWindow" xmlns:mx="http://www.adobe.com/2006/mxml" title="Logon" x="350" y="80">
  <mx:Form>
   <mx:FormItem label="Lusername" required="true">
    <mx:TextInput id="username" width="150">
    </mx:TextInput>
   </mx:FormItem>
   <mx:FormItem label="LPassword" required="true">
    <mx:TextInput id="password"  width="150" displayAsPassword="true"/>
   </mx:FormItem>
   <mx:FormItem>
    <mx:HBox horizontalGap="30">
     <mx:Button label="Logon" click="info.send();" />
     <mx:Button label="Cancel" click="info.send();"/>
    </mx:HBox>
   </mx:FormItem>
  </mx:Form>
 </mx:TitleWindow>
 
 <mx:DataGrid dataProvider="{info.lastResult.userinfo.user}" width="60%" x="160" y="300" >
  <mx:columns>
   <mx:Array>
    <mx:DataGridColumn headerText="姓名" dataField="username"/>
    <mx:DataGridColumn headerText="密码" dataField="userpwd"/>
    <mx:DataGridColumn headerText="邮件" dataField="useremail"/>
    <mx:DataGridColumn headerText="年龄" dataField="userage"/>
   </mx:Array>
  </mx:columns>
