@Data注解，自动生成Getter和Setter方法，与UserDetails中的isEnabled()方法冲突

紧接着上一篇，这篇实现我们的操作员管理

1.操作员管理

有关对管理员的操作无非也就是增删改（角色、操作员）查（角色、操作员），但是查包括精确查询和模糊查询，所以SQL语句需要我们自己写。还有就是我们在Admin实体类中使用了@Data注解，它会自动生成Getter和Setter方法，但是这与UserDetails中的isEnabled()方法冲突，系统无法分辨，所以我们需要规定该用哪一个。在enabled属性上添加@Getter(AccessLevel.NONE)注解让其不会生成Getter方法。

1.1.功能实现

1.1.1.修改实体类

Admin.java

@Data
@EqualsAndHashCode(callSuper = false)
@TableName("t_admin")
@ApiModel(value="Admin对象", description="")
public class Admin implements Serializable , UserDetails {

	......
    @ApiModelProperty(value = "联系地址")
    private String address;

    @ApiModelProperty(value = "是否启用")
    @Getter(AccessLevel.NONE)
    private Boolean enabled;
	......
}

1.1.1.修改对应映射文件

AdminMapper.xml

<resultMap id="AdminWithRole" type="com.kt.pojo.Admin" extends="BaseResultMap">
        <collection property="roles" ofType="com.kt.pojo.Role">
            <id column="rid" property="id"/>
            <result column="rname" property="name"/>
            <result column="rnameZh" property="nameZh"/>
        collection>
    resultMap>

    <select id="getAllAdmins" resultMap="AdminWithRole">
        SELECT DISTINCT
        a.*,
        r.id AS rid,
        r.`name` AS rname,
        r.nameZh AS rnameZh
        FROM
        t_admin a
        LEFT JOIN t_admin_role ar ON a.id = ar.adminId
        LEFT JOIN t_role r ON r.id = ar.rid
        WHERE
        a.id != #{id}
        <if test="null!=keywords and ''!=keywords">
            AND a.`name` LIKE CONCAT( '%', #{keywords}, '%' )
        if>
        ORDER BY
        a.id
    select>

AdminRoleMapper.xml

    <update id="updateAdminRole">
        insert into t_admin_role(adminId, rid) values
        <foreach collection="rids" item="rid" separator=",">
            (#{adminId}, #{rid})
        foreach>
    update>

1.1.2.Mapper接口

Admin.java

public interface AdminMapper extends BaseMapper<Admin> {

    /**
     * 获取所有操作员
     * @param id
     * @param keywords
     * @return
     */
    List<Admin> getAllAdmins(@Param("id") Integer id, @Param("keywords") String keywords);
}

AdminRoleMapper.java

public interface AdminRoleMapper extends BaseMapper<AdminRole> {
    /**
     * 更新操作员角色
     * @param adminId
     * @param rids
     * @return
     */
    Integer updateAdminRole(@Param("adminId") Integer adminId, @Param("rids") Integer[] rids);
}

1.1.3.服务类

IAdminService.java

public interface IAdminService extends IService<Admin> {

    /**
     * 登录之后返回Token
     * @param username
     * @param password
     * @param code
     * @param request
     * @return
     */
    RespBean login(String username, String password, String code, HttpServletRequest request);

    /**
     * 根据用户名获取用户
     * @param username
     * @return
     */
    Admin getAdminByUserName(String username);

    /**
     * 根据用户id查询角色列表
     * @param adminId
     * @return
     */
    List<Role> getRoles(Integer adminId);

    /**
     * 获取所有操作员
     * @param keywords
     * @return
     */
    List<Admin> getAllAdmins(String keywords);

    /**
     * 更新操作员角色
     * @param adminId
     * @param rids
     * @return
     */
    RespBean updateAdminRole(Integer adminId, Integer[] rids);
}

1.1.4.服务实现类

AdminServiceImpl.java

@Service
public class AdminServiceImpl extends ServiceImpl<AdminMapper, Admin> implements IAdminService {

	......
    
    @Override
    public Admin getAdminByUserName(String username) {
        // 用户名、启用状态
        return adminMapper.selectOne(new QueryWrapper<Admin>().eq("username", username).eq("enabled", true));
    }

    @Override
    public List<Role> getRoles(Integer adminId) {
        return roleMapper.getRoles(adminId);
    }

    @Override
    public List<Admin> getAllAdmins(String keywords) {
        return adminMapper.getAllAdmins(AdminUtils.getCurrentAdmin().getId(), keywords);
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public RespBean updateAdminRole(Integer adminId, Integer[] rids) {
        adminRoleMapper.delete(new QueryWrapper<AdminRole>().eq("adminId", adminId));
        Integer result = adminRoleMapper.updateAdminRole(adminId, rids);
        if (rids.length == result) {
            return RespBean.success("更新成功！");
        }
        return RespBean.error("更新失败！");
    }
}

1.1.5.控制类

AdminController.java

@RestController
@RequestMapping("/system/admin")
public class AdminController {

    @Resource
    private IAdminService adminService;
    @Resource
    private IRoleService roleService;

    @ApiOperation(value = "获取所有操作员")
    @GetMapping("/")
    public List<Admin> getAllAdmins(String keywords) {
        return adminService.getAllAdmins(keywords);
    }

    @ApiOperation(value = "更新操作员")
    @PutMapping("/")
    public RespBean updateAdmin(@RequestBody Admin admin) {
        if (adminService.updateById(admin)) {
            return RespBean.success("更新成功！");
        }
        return RespBean.error("更新失败！");
    }

    @ApiOperation(value = "删除操作员")
    @DeleteMapping("/{id}")
    public RespBean deleteAdmin(@PathVariable Integer id) {
        if (adminService.removeById(id)) {
            return RespBean.success("删除成功！");
        }
        return RespBean.error("删除失败！");
    }

    @ApiOperation(value = "获取所有角色")
    @GetMapping("/roles")
    public List<Role> getAllRoles() {
        return roleService.list();
    }

    @ApiOperation(value = "更新操作员角色")
    @PutMapping("/role")
    public RespBean updateAdminRole(Integer adminId, Integer[] rids) {
        return adminService.updateAdminRole(adminId, rids);
    }

}

1.2.测试

获取所有操作员：

更新操作员（我直接copy上面的数据进行更新，将安淑华123改为华，密码不修改，不要“authority”参数）：

{
    "id": 3,
    "name": "安淑华123",
    "phone": "14588110811",
    "telephone": "50603155",
    "address": "山东省凤英县长寿银川街l座",
    "enabled": true,
    "username": "naqiao",
    "userFace": "http://desiy.oss-cn-chengdu.aliyuncs.com/img/testavatar.jpg",
    "remark": null,
    "roles": [
      {
        "id": 3,
        "name": "ROLE_recruiter",
        "nameZh": "招聘主管"
      },
      {
        "id": 4,
        "name": "ROLE_train",
        "nameZh": "培训主管"
      }
    ],
    "accountNonLocked": true,
    "credentialsNonExpired": true,
    "accountNonExpired": true
  }

删除操作员功能这里就不演示了。

获取所有角色：
