LoginAction.java

感觉这样写还行：
LoginAction.java

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;

import com.yuqiaotech.simplejee.dao.UserDaoHibernate;
import com.yuqiaotech.simplejee.model.User;
/**

@Results({
        @Result(name="login",location="/ssh/login.jsp"),
        @Result(name="index",type="redirect",location="/index.html")
})
public class LoginAction {
        private String username;
        private String password;
        private UserDaoHibernate userDao;
        public String execute(){
                User u = userDao.findUserByUsername(username);
                if(u == null)return "login";
                if(!password.equals(u.getPassword()))return "login";
                ServletActionContext.getRequest().getSession().setAttribute("currentUser", u);
                return "index";
        }
        public String getUsername() {
                return username;
        }
        /**
         * struts2的拦截器通过本方法将界面上传来的username的值注入本action的实例。
         * @param username
         */
        public void setUsername(String username) {
                this.username = username;
        }
        public String getPassword() {
                return password;
        }
        public void setPassword(String password) {
                this.password = password;
        }
        public UserDaoHibernate getUserDao() {
                return userDao;
        }
        /**
         * spring通过本方法注入id为userDao的UserDaoHibernate对象。

                this.userDao = userDao;
        }
        
        
}
