一、前言

角色是基于业务管理需求而预先在系统中设定好的固定标签,每个角色需对应明确的系统权限,其所拥有的系统权限一般不会随意更改,并且角色也不会随着用户的被添加和被移除而进行改变,相较于用户管理而言更加稳定。

  • 本文将实现角色管理的增删改查

二、后端实现

2.1 创建角色实体类

/** * 角色表 * * @author zhuhuix * @date 2021-09-03 */
@ApiModel(value = "角色表")
@Data
@SuperBuilder
@NoArgsConstructor
@AllArgsConstructor
@TableName("sys_role")
public class SysRole implements Serializable {
    @TableId(value = "id", type = IdType.AUTO)
    private Long id;

    private String roleCode;

    private String roleName;

    private String description;

    @TableLogic
    private Boolean enabled;

    private Timestamp createTime;

    @Builder.Default
    private Timestamp updateTime = Timestamp.valueOf(LocalDateTime.now());
}

2.1 添加角色Mapper接口

/** * 角色DAO接口 * * @author zhuhuix * @date 2021-09-13 */
@Mapper
public interface SysRoleMapper extends BaseMapper<SysRole> {
}

2.3 实现角色增删改查服务

/** * 角色信息接口 * * @author zhuhuix * @date 2021-09-13 */
public interface SysRoleService {

    /** * 增加角色 * * @param role 待新增的角色 * @return 增加成功的角色 */
    SysRole create(SysRole role);

    /** * 删除角色 * * @param role 待删除的角色 * @return 已删除的角色 */
    SysRole delete(SysRole role);

    /** * 修改角色 * * @param role 待修改的角色 * @return 修改成功的角色 */
    SysRole update(SysRole role);

    /** * 根据角色代码查找角色 * * @param roleCode 角色代码 * @return 增加成功的角色 */
    SysRole findByRoleCode(String roleCode);

    /** * 根据角色名称查找角色 * * @param roleName 角色代码 * @return 增加成功的角色 */
    SysRole findByRoleName(String roleName);

    /** * 获取全部角色信息 * @return 角色列表 */
    List<SysRole> findAll();

	/** * 根据条件查询角色 * @param roleQueryDto 查询条件 * @return 角色列表 */
    List<SysRole> list( RoleQueryDto roleQueryDto);

}
/** * 角色服务实现类 * * @author zhuhuix * @date 2021-09-13 */
@Slf4j
@Service
@RequiredArgsConstructor
@Transactional(propagation = Propagation.SUPPORTS, readOnly = true, rollbackFor = Exception.class)
public class SysRoleServiceImpl implements SysRoleService {

    private final SysRoleMapper sysRoleMapper;

    @Override
    @Transactional(rollbackFor = Exception.class)
    public SysRole create(SysRole role) {
        if (findByRoleCode(role.getRoleCode()) != null || findByRoleCode(role.getRoleName()) != null) {
            throw new RuntimeException("该角色已存在,不得重复添加!!");
        }

        if (sysRoleMapper.insert(role) > 0) {
            return role;
        }
        throw new RuntimeException("增加角色信息失败");
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public SysRole delete(SysRole role) {
        QueryWrapper<SysRole> queryWrapper = new QueryWrapper<>();
        queryWrapper.lambda().eq(SysRole::getRoleCode, role.getRoleCode());
        if (sysRoleMapper.delete(queryWrapper) > 0) {
            return role;
        }
        throw new RuntimeException("删除角色信息失败");
    }

    @Override
    @Transactional(rollbackFor = Exception.class)
    public SysRole update(SysRole role) {
        if (sysRoleMapper.updateById(role) > 0) {
            return role;
        }
        throw new RuntimeException("修改角色信息失败");
    }

    @Override
    public SysRole findByRoleCode(String roleCode) {
        QueryWrapper<SysRole> queryWrapper = new QueryWrapper<>();
        queryWrapper.lambda().eq(SysRole::getRoleCode, roleCode);
        return sysRoleMapper.selectOne(queryWrapper);
    }

    @Override
    public SysRole findByRoleName(String roleName) {
        QueryWrapper<SysRole> queryWrapper = new QueryWrapper<>();
        queryWrapper.lambda().eq(SysRole::getRoleName, roleName);
        return sysRoleMapper.selectOne(queryWrapper);
    }

    @Override
    public List<SysRole> findAll() {
        QueryWrapper<SysRole> queryWrapper = new QueryWrapper<>();

        return sysRoleMapper.selectList(queryWrapper);
    }

	 @Override
    public List<SysRole> list(RoleQueryDto roleQueryDto) {
        QueryWrapper<SysRole> queryWrapper = new QueryWrapper<>();
        if (!StringUtils.isEmpty(roleQueryDto.getRoleName())) {
            queryWrapper.lambda().like(SysRole::getRoleName, roleQueryDto.getRoleName());
        }
        if (!StringUtils.isEmpty(roleQueryDto.getCreateTimeStart())
                && !StringUtils.isEmpty(roleQueryDto.getCreateTimeEnd())) {
            queryWrapper.lambda().between(SysRole::getCreateTime,
                    new Timestamp(roleQueryDto.getCreateTimeStart()),
                    new Timestamp(roleQueryDto.getCreateTimeEnd()));
        }
        return sysRoleMapper.selectList(queryWrapper);
    }
}

2.4 编写Controller层

  • 共实现以下6个后台接口

/** * 角色信息api * * @author zhuhuix * @date 2021-09-13 */
@Slf4j
@RestController
@AllArgsConstructor
@RequestMapping("/api/role")
@Api(tags = "角色信息接口")
public class SysRoleController {

    private final SysRoleService sysRoleService;

    @ApiOperation("根据条件查询角色信息")
    @PostMapping("/list")
    public Object getRoleList(@RequestBody RoleQueryDto roleQueryDto) {
        return sysRoleService.list(roleQueryDto);
    }

    @ApiOperation("根据id获取单个角色信息")
    @GetMapping("{id}")
    public ResponseEntity<Object> getRoleById(@PathVariable Long id) {
        return ResponseEntity.ok(sysRoleService.findById(id));
    }

    @ApiOperation("根据角色编码获取单个角色信息")
    @GetMapping("/roleCode/{roleCode}")
    public ResponseEntity<Object> getRoleByRoleCode(@PathVariable String roleCode) {
        return ResponseEntity.ok(sysRoleService.findByRoleCode(roleCode));
    }

    @ApiOperation("获取所有角色信息")
    @GetMapping()
    public ResponseEntity<Object> getAllRole() {
        return ResponseEntity.ok(sysRoleService.findAll());
    }

    @ApiOperation("保存角色信息")
    @PostMapping
    public ResponseEntity<Object> saveRole(@RequestBody SysRole role) {
        if (role.getId() != null) {
            return ResponseEntity.ok(sysRoleService.update(role));
        } else {
            return ResponseEntity.ok(sysRoleService.create(role));
        }
    }

    @ApiOperation("删除角色信息")
    @DeleteMapping
    public ResponseEntity<Object> deleteRole(@RequestBody Set<Long> ids) {
        return ResponseEntity.ok(sysRoleService.delete(ids));
    }
}

三、前端实现

3.1 添加角色api访问接口

  • src/api/role.js
import request from '@/utils/request'

export function getAllRole() {
  return request({
    url: '/api/role',
    method: 'get'
  })
}

export function getRole(id) {
  return request({
    url: '/api/role/' + id,
    method: 'get'
  })
}

export function saveRole(data) {
  return request({
    url: '/api/role',
    method: 'post',
    data
  })
}

export function deleteRole(ids) {
  return request({
    url: '/api/role',
    method: 'delete',
    data: ids
  })
}

export function getRoleList(params) {
  return request({
    url: '/api/role/list',
    method: 'post',
    data: JSON.stringify(params)
  })
}

3.2 编写前端页面

  • 我们需要编写一个完整的页面:
  1. 通过角色名与创建起始与结束时间查询角色,并用卡片的形式进行显示。
  2. 通过点击“新增”按钮,跳出表单,输入角色信息后保存角色。
  3. 通过点击角色卡片上的“编辑”按钮,对原有角色信息进行更新。
  4. 通过点击角色卡片上的“删除”按钮,删除角色信息,删除前要有提示。
