狂神说java超市管理系统service层

本文主要是介绍狂神说java超市管理系统service层，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

接口

package service.LogService.RoleService;

import po.role;

import java.sql.Connection;
import java.sql.SQLException;
import java.util.List;

public interface RoleList {
    public List<role> RoleListService() throws SQLException, ClassNotFoundException;
}

 

package service.LogService;

import po.user;

import java.sql.Connection;
import java.sql.SQLException;
import java.util.Date;
import java.util.List;

public interface LoginService {
    //登入接口
    public user Login(String User,String pwd) throws SQLException, ClassNotFoundException;
    //修改密码接口
    public  boolean UppwdService(int id,String pwd) throws SQLException, ClassNotFoundException;
    //获取人员数量
    public  int CountService(String Username,int id) throws SQLException, ClassNotFoundException;
    //获取人员信息
    public List <user> UserList(String UserName, int id,int a,int b) throws SQLException, ClassNotFoundException;
    //添加用户
    public boolean adduser(user user) throws SQLException, ClassNotFoundException;
    //查询用户是否存在
    public  boolean exuser(String user);
    //删除用户
    public boolean deluser(int id);
    //根据ID查询用户
    public  user selectuser(int id);
    //更新用户信息
    public Boolean UPuser(user user);
}

实现类

package service.LogService.RoleService;

import dao.BaseDao;
import dao.Role.RoleListimpl;
import po.role;
import service.LogService.RoleService.RoleList;

import java.sql.Connection;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

public class RoleListServiceimpl implements RoleList {
    public List<role> RoleListService() {
        Connection conn  = null;
        try {
            conn = BaseDao.GetConn();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
        RoleListimpl roleListimpl = new RoleListimpl();
        List<role> roles = null;
        try {
            roles = roleListimpl.SelectRole(conn);
        } catch (SQLException e) {
            e.printStackTrace();
