Struts1的一个简单示例：用户登陆

开发步骤:
1.导入jar包，配置相关文件.
可以先配置web.xml文件，如下：

<?xml version="1.0" encoding="UTF-8"?>
2

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
3

<servlet>
4

<servlet-name>actionServlet</servlet-name>
5

<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
6

<init-param>
7

<param-name>config</param-name>
8

<param-value>/WEB-INF/struts-config.xml</param-value>
9

</init-param>
10

<load-on-startup>0</load-on-startup>
11

</servlet>
12

<servlet-mapping>
13

<servlet-name>actionServlet</servlet-name>
14

<url-pattern>*.do</url-pattern>
15

</servlet-mapping>
16

</web-app>

在WEB-INF下建立一个struts-config.xml文件，文件内容暂且如下：

<?xml version="1.0" encoding="gbk" ?>
2

<!DOCTYPE struts-config PUBLIC
4

"-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
5

"http://struts.apache.org/dtds/struts-config_1_3.dtd">
6

<struts-config>
7

</struts-config>

2.书写jsp页面：login.jsp,success.jsp,error.jsp
login.jsp:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
2

pageEncoding="ISO-8859-1"%>
3

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
4

<html>
5

<head>
6

<title>Insert title here</title>
8

</head>
9

<body>
10

<form action="login.do" method="post">
11

username:<input type="text" name="username" /> <br/>
12

password:<input type="password" name="password" /> <br/>
13

<input type="submit" value="submit"/>
14

</form>
15

</body>
16

</html>

success.jsp:

<body>
2

<h1>login success !</h1>
3

<h2>username:${requestScope.username}</h2>
4

<h2>password:${requestScope.password}</h2>
5

</body>

error.jsp:

<body>
2

<h1><font color="red">login failed !</font></h1>
3

</body>

3.编写一个ActionForm的类，用来暂存请求传给服务端的数据。

package per.struts1.web;
2

import org.apache.struts.action.ActionForm;
3

public class LoginActionForm extends ActionForm {
4

private String username;
5

private String password;
6

public String getUsername() {
7

return username;
8

}
9

public void setUsername(String username) {
10

System.out.println(username);
11

this.username = username;
12

}
13

public String getPassword() {
14

return password;
15

}
16

public void setPassword(String password) {
17

System.out.println(password);
18

this.password = password;
19

}
20

}
21

4.编写一个Action类，并覆盖其execute()方法

package per.struts1.web;
2

import javax.servlet.http.HttpServletRequest;
3

import javax.servlet.http.HttpServletResponse;
4

import org.apache.struts.action.Action;
5

import org.apache.struts.action.ActionForm;
6

import org.apache.struts.action.ActionForward;
7

import org.apache.struts.action.ActionMapping;
8

public class LoginAction extends Action {
9

@Override
10

public ActionForward execute(ActionMapping mapping, ActionForm form,
11

HttpServletRequest request, HttpServletResponse response)
12

throws Exception {
13

LoginActionForm laf = (LoginActionForm)form;
14

String username = laf.getUsername();
15

String password = laf.getPassword();
16

System.out.println(username+":"+password);
17

if("jone".equals(username)&&"jone".equals(password)){
18

request.setAttribute("username", username);
19

request.setAttribute("password", password);
20

return mapping.findForward("success");
21

}else{
22

return mapping.findForward("error");
23

}
24

}
25

}
26

5.对ActionForm类及Action类在struts-config.xml文件中进行配置

<?xml version="1.0" encoding="gbk" ?>
2

<!DOCTYPE struts-config PUBLIC
3

"-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
4

"http://struts.apache.org/dtds/struts-config_1_3.dtd">
5

<struts-config>
6

<form-beans>
7

<form-bean name="loginForm" type="per.struts1.web.LoginActionForm" >
8

9

</form-bean>
10

</form-beans>
11

<action-mappings>
13

<action path="/login" type="per.struts1.web.LoginAction" name="loginForm" scope="request" >
14

<!-- 为Action类进行配置,-条action标签对应一个ActionMapping类，path为访问路径，不含.do，
15

type为类的全限定名，name指的是上面已经配置的ActionForm的name值，
16

scope为所创建的ActionForm指明一个作用域。
17

-->
18

<forward name="success" path="/success.jsp"></forward>
19

20

<forward name="error" path="/error.jsp"></forward>
21

</action>
22

</action-mappings>
23

</struts-config>
24

至此可以进行运行测试了。只有当username与password都为"jone"的时候，才会跳到success.jsp页面。
