import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport    {
private boolean success;
private String message;
private User user;
@Override
    public String execute() throws Exception {
        if(user.getUsername().equals("admin")&&user.getPassword().equals("admin")){
            this.success= true;
            //this.message="你的账号是："+user.getUsername()+"密码是："+user.getPassword();
        }else{
            this.success=false;
            this.message="对不起，未授权的用户不能登录改系统";
        }
        return SUCCESS;
    }
public boolean isSuccess() {
    return success;
}
public void setSuccess(boolean success) {
    this.success = success;
}
public String getMessage() {
    return message;
}
public void setMessage(String message) {
