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> ?</mx:DataGrid> ? </mx:Application>
