</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
</web-app>
2.新建service包以及LoginService.java:
package com.struts2.service;
public interface LoginService {
public boolean isLogin(String username, String password);
}
3.新建action包以及LoginAction.java:
package com.struts2.action;
import com.opensymphony.xwork2.ActionSupport;
import com.struts2.service.LoginService;
public class LoginAction extends ActionSupport{
private String username;
private String password;
private LoginService loginService;
public LoginService getLoginService() {
return loginService;
}
public void setLoginService(LoginService loginService) {
this.loginService = loginService;
}
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;
}
public String execute() throws Exception{
if(loginService.isLogin(username, password)){
return "success";
}
return "input";
}
}
4.新建impl包以及LoginServiceImpl.java:
package com.struts2.service.impl;
import com.struts2.service.LoginService;
public class LoginServiceImpl implements LoginService {
@Override
public boolean isLogin(String username, String password) {
if("xzz".equals(username) && "123".equals(password)){
return true;
}
return false;
}
}
5.配置applicationContext.xml:

<bean id="loginAction" class="com.struts2.action.LoginAction">
<property name="loginService" ref="loginService"></property>
</bean>
</beans>
6.配置struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
