LoginAction.java

package com.struts2.action;

import com.opensymphony.xwork2.ActionSupport;
import com.struts2.service.LoginService;

public class LoginAction extends ActionSupport {

private LoginService loginService;
private String username;
private String password;
public String getUsername() {

}
public void setUsername(String username) {

if(loginService.isLogin(username, password))
{
return SUCCESS;
}
return INPUT;
}
public void setLoginService(LoginService loginService) {
this.loginService = loginService;
}

}

接口：LoginService.java

package com.struts2.service;

public interface LoginService {
public boolean isLogin(String username, String password);
}

业务逻辑类实现：LoginServiceImpl.java

package com.struts2.service.impl;

import com.struts2.service.LoginService;

public class LoginServiceImpl implements LoginService {

public boolean isLogin(String username, String password) {

if("hello".equals(username) && "world".equals(password))
{
return true;
}
return false;
}

}
