在src下新建一个xml文件struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="struts2" extends="struts-default">
<action name="login" class="com.sshlearn.action.LoginAction">
<result name="success">/result.jsp</result>
</action>
</package>
</struts>
src下新建一个package com.sshlearn.action，并新建class loginAction
package com.sshlearn.action;
public class LoginAction {
private String username;
private String password;
public String execute() {
System.out.println(username+"==="+password);
return "success";
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
