我的后端是用java的ssh框架實現(xiàn)的
package cn.com.service;
import java.io.IOException;
import java.util.List;
import javax.servlet.http.HttpServletResponse;
import net.sf.json.JSONArray;
import org.apache.struts2.ServletActionContext;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.opensymphony.xwork2.ModelDriven;
import cn.com.bean.User;
@Repository(value = "ulogin")
@Scope("prototype")
public class Ulogin implements ModelDriven<User> {
@Autowired
private SessionFactory sf;
@Autowired
private User u;
// 注冊功能
@Transactional
public String regedit() {
Session session = sf.getCurrentSession();
session.save(u);
return null;
}
// 登錄功能
@Transactional
public String login() {
Session session = sf.getCurrentSession();
String sql = "from User where username=? and password=?";
Query query = session.createQuery(sql);
query.setString(0, u.getUsername());
query.setString(1, u.getPassword());
User uu = (User) query.uniqueResult();
String info = null;
if (uu != null) {
info = "success";
} else {
info = "fail";
}
HttpServletResponse response = ServletActionContext.getResponse();
response.setCharacterEncoding("utf-8");
try {
response.getWriter().write(info);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
@Override
public User getModel() {
// TODO Auto-generated method stub
return u;
}
}
