原代码如下：
LoginService.java
package org.test.service;
public interface LoginService {
public boolean isLogin(String username,String password);
}

LoginServiceImpl .java

package org.test.service.impl;

import org.test.service.LoginService;

public class LoginServiceImpl implements LoginService {

public boolean isLogin(String username, String password) {
//判断用户所以输入的数据是否为gao,qin，如果是则登陆成功,否则失败
// TODO Auto-generated method stub
if(username.equals("gao") && password.equals("qin")){
return true;
}
return false;
}

}

LoginAction.java

package org.test.struts2Action;

import org.test.service.LoginService;

import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class LoginAction extends ActionSupport {
private String username;
private String password;
@SuppressWarnings("unused")
private LoginService loginService;
@Override
public String execute() throws Exception {
if(loginService.isLogin(username, password)){
return SUCCESS;
}
return INPUT;
}
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 void setLoginService(LoginService loginService) {
this.loginService = loginService;
}
}
