RBAC原则设计Friday权限管理系统（3）

编写用户表接口

1、前置知识

controller：控制层

service：业务层

repository：数据控制访问层

2、编写接口步骤

3、编写三层结构代码

控制层（SysUserController） package edu.friday.controller;import edu.friday.common.base.BaseController;import edu.friday.common.result.RestResult;import edu.friday.service.SysUserService;import org.springframework.搭建商城点我wcqh.cnbeans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * 用户表 控制层 * */@RestController@RequestMapping(“/system/user”)publicclassSysUserContro搭建商城点我wcqh.cnllerextendsBaseController{@AutowiredSysUserService sysUserService;/** * 显示所有用户 * */@GetMapping(“/list”)publicRestResult list(){returnRestResult.success(“操作成功！”,sysUserService.selectUserList());}}

业务层

业务层分为业务层接口（SysUserService）和业务层实现（SysUserServiceImpl） package edu.friday.service;import edu.friday.model.SysUs搭建商城点我wcqh.cner;import java.util.List;/** * 用户表 业务层接口 * */publicinterfaceSysUserService{List<SysUser> selectUserList();} package edu.friday.service.impl;import edu.friday.model.SysUser;import edu.friday.repository.SysUserRepository;import edu.friday.service.SysUserService;import org.springframework.beans.factory.annotatio搭建商城点我wcqh.cnn.Autowired;import org.springframework.stereotype.Service;import java.util.List;/** * 用户表 业务层 * */@ServicepublicclassSysUserServiceImplimplementsSysUserService{@AutowiredSysUserRepository sysUserRepository;/** * 显示所有用户列表 * */@OverridepublicList<SysUser> selectUserList(){return sysUserRepository.findAll();}}数搭建商城点我wcqh.cn据控制访问层（SysUserRepository）package edu.friday.repository;import edu.friday.model.SysUser;import org.springframework.data.jpa.repository.JpaRepository;import org.springframework.stereotype.Repository;/** * 用户表 数据层 * */@RepositorypublicinterfaceSysUserRepositoryextendsJpaRepository<SysUser,Long>{}
