6.1.2 后端环境
-
基本内容:JavaBean、Mapper、Service、Controller
-
JavaBean
-
基本结构
-
6.2 用户管理
6.2.1 查询所有用户(关联角色)
1)后端
-
修改javaBean:
List<SysRole> roleList
-
编写Mapper:使用注解的方式查询关联数据
-
编写Service
-
编写Controller
-
修改javaBean:
List<SysRole> roleList
-
编写Mapper:使用注解的方式查询关联数据
-
修改UserMapper:查询所有,含角色
package com.czxy.classes.mapper; import com.baomidou.mybatisplus.core.mapper.BaseMapper; import com.czxy.domain.TbUser; import org.apache.ibatis.annotations.*; import java.util.List; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @Mapper public interface TbUserMapper extends BaseMapper<TbUser> { @Select("SELECT * FROM tb_user") @Results({ @Result(property = "uid", column = "u_id"), @Result(property = "userName", column = "user_name"), @Result(property = "password", column = "password"), @Result(property = "gender", column = "gender"), @Result(property = "image", column = "image"), @Result(property = "roleList", many = @Many(select = "com.czxy.classes.mapper.SysRoleMapper.findAllByUid") , column = "u_id") }) public List<TbUser> findAll(); }
-
修改RoleMapper:查询指定用户的角色
package com.czxy.classes.mapper; import com.baomidou.mybatisplus.core.mapper.BaseMapper; import com.czxy.sys.SysRole; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select; import java.util.List; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @Mapper public interface SysRoleMapper extends BaseMapper<SysRole> { /** * 查询指定用户的所有角色 * @author 桐叔 * @email liangtong@itcast.cn * @return */ @Select("SELECT r.* FROM sys_role r, sys_user_role ur WHERE r.id = ur.role_id AND ur.user_id = #{uid}") public List<SysRole> findAllByUid(@Param("uid") String uid); }
-
-
编写Service
package com.czxy.classes.service; import com.baomidou.mybatisplus.extension.service.IService; import com.czxy.domain.TbUser; import java.util.List; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ public interface TbUserService extends IService<TbUser> { public List<TbUser> findAll(); }
package com.czxy.classes.service.impl; import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper; import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl; import com.czxy.domain.TbUser; import com.czxy.classes.mapper.TbUserMapper; import com.czxy.classes.service.TbUserService; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import java.util.List; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @Service @Transactional public class TbUserServiceImpl extends ServiceImpl<TbUserMapper, TbUser> implements TbUserService { @Override public List<TbUser> findAll() { return baseMapper.findAll(); } }
-
编写Controller
package com.czxy.classes.controller; import com.czxy.classes.config.JwtProperties; import com.czxy.classes.utils.JwtUtils; import com.czxy.domain.TbUser; import com.czxy.classes.service.TbUserService; import com.czxy.vo.BaseResult; import org.springframework.web.bind.annotation.*; import javax.annotation.Resource; import java.util.List; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @RestController @RequestMapping("/user") public class TbUserController { @Resource private TbUserService tbUserService; @GetMapping public BaseResult findAll() { List<TbUser> list = tbUserService.findAll(); return BaseResult.ok("查询成功", list); } }
2)前端

6.2.2 核心1:给用户授予角色
1)分析
-
前置功能:查询所有的角色
-
后端:查询所有
-
前端:下拉列表展示
-
-
核心:给用户授予角色
-
完成修改的部分功能,将用户选择的角色更新到数据库(先删除、后添加)
-
后端:用户角色直接操作,给一个用户,添加一组角色
-
前端:弹出框,直接使用table中的数据填充前端额下拉列表
-
2)前置功能:查询所有的角色-后端
package com.czxy.classes.controller;
import com.czxy.classes.service.SysRoleService;
import com.czxy.sys.SysRole;
import com.czxy.vo.BaseResult;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;
import java.util.List;
/**

*/
@RestController
@RequestMapping("/role")
public class SysRoleController {
@Resource
private SysRoleService sysRoleService;
@GetMapping
public BaseResult findAll() {
List<SysRole> list = sysRoleService.list();
return BaseResult.ok("查询成功", list);
}
}
3)核心:给用户授予角色-后端
-
用户角色直接操作,给一个用户,添加一组角色
-
编写mapper:通过uid删除关联信息
-
编写service:先删除后,后添加
-
编写controller
-
编写mapper:通过uid删除关联信息
package com.czxy.classes.mapper; import com.baomidou.mybatisplus.core.mapper.BaseMapper; import com.czxy.sys.SysRole; import com.czxy.sys.SysUserRole; import org.apache.ibatis.annotations.Delete; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @Mapper public interface SysUserRoleMapper extends BaseMapper<SysUserRole> { @Delete("DELETE FROM sys_user_role WHERE user_id = #{uid}") int deleteByUid(@Param("uid") String uid); }
-
编写service:先删除后,后添加
package com.czxy.classes.service; import com.baomidou.mybatisplus.extension.service.IService; import com.czxy.domain.TbUser; import com.czxy.sys.SysUserRole; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @Service @Transactional public interface SysUserRoleService extends IService<SysUserRole> { /** * 给指定用户收取角色 * @author 桐叔 * @email liangtong@itcast.cn * @return */ void addRoleWithUser(TbUser tbUser); }
package com.czxy.classes.service.impl; import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl; import com.czxy.classes.mapper.SysUserRoleMapper; import com.czxy.classes.service.SysUserRoleService; import com.czxy.domain.TbUser; import com.czxy.sys.SysUserRole; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @Service @Transactional public class SysUserRoleServiceImpl extends ServiceImpl<SysUserRoleMapper, SysUserRole> implements SysUserRoleService { @Override public void addRoleWithUser(TbUser tbUser) { //1 删除 baseMapper.deleteByUid(tbUser.getUid()); //2 添加 for (Integer roleId : tbUser.getRoleIds()) { SysUserRole sysUserRole = new SysUserRole(tbUser.getUid(), roleId); baseMapper.insert(sysUserRole); } } }
-
编写controller
package com.czxy.classes.controller; import com.czxy.classes.service.SysUserRoleService; import com.czxy.domain.TbUser; import com.czxy.vo.BaseResult; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import javax.annotation.Resource; /** * @author 桐叔 * @email liangtong@itcast.cn * @description */ @RestController @RequestMapping("/userRole") public class SysUserRoleController { @Resource private SysUserRoleService sysUserRoleService; @PostMapping("/addRoleWithUser") public BaseResult addRoleWithUser(@RequestBody TbUser tbUser) { // 给用户添加角色 sysUserRoleService.addRoleWithUser(tbUser); return BaseResult.ok("授权成功"); } }
