五、实现代码 

1、角色控制器

/*** <p>* 角色表 前端控制器* </p>** @author CeaM* @since 2023-01-28*/
@RestController
@AllArgsConstructor
@RequestMapping("/api/roles/v1")
public class CeamSysRoleController {private final ICeamSysRoleService ceamSysRoleService;private final ICeamSysUserService ceamSysUserService;@GetMappingpublic R<IPage<CeaMSysRoleVO>> getRoles(CeaMSysRoleDTO data) {IPage<CeaMSysRoleVO> mapIPage = ceamSysRoleService.pageCeaMSysRoleVO(data);return R.ok(mapIPage);}@GetMapping("all")public R<Object> getAll() {List<CeamSysRole> list = ceamSysRoleService.list();return R.ok(list);}@GetMapping(value = "/level")public R<Object> getLevel() {return R.ok(Dict.create().set("level", getLevels(null)));}@PutMapping(value = "/menu")public R<Object> updateMenu(@RequestBody CeaMSysRoleDTO roleDTO) {CeamSysRole role = ceamSysRoleService.getById(roleDTO.getId());getLevels(role.getLevel());ceamSysRoleService.updateMenu(roleDTO, role);return R.ok(HttpStatus.NO_CONTENT);}@PostMapping("/add")public R<Object> add(@RequestBody CeaMSysRoleDTO data) {boolean edit = ceamSysRoleService.add(data);return R.ok(edit);}@PutMapping("/edit")public R<Object> edit(@RequestBody CeaMSysRoleDTO data) {boolean edit = ceamSysRoleService.edit(data);return R.ok(edit);}@DeleteMapping("/del")public R<Object> remove(@RequestBody Set<Long> ids) {ceamSysRoleService.remove(ids);return R.ok("成功");}/*** 获取用户的角色级别* @return /*/private int getLevels(Integer level) {CeaMSysUserDTO user = ceamSysUserService.loadUserInfo(SecurityUtils.getUsername());List<RoleDTO> roleDTOS = ceamSysRoleService.listByUserId(user.getId());List<Integer> levels = roleDTOS.stream().map(RoleDTO::getLevel).collect(Collectors.toList());int min = Collections.min(levels);if (level != null) {if (level < min) {throw new ServiceException("权限不足，你的角色级别：" + min + "，低于操作的角色级别：" + level);}}return min;}
}

2、服务接口

/*** <p>* 角色表 服务类* </p>** @author CeaM* @since 2023-01-28*/
public interface ICeamSysRoleService extends IService<CeamSysRole> {IPage<CeaMSysRoleVO> pageCeaMSysRoleVO(PageableDTO pageable);/*** 获取用户权限信息* @param userId 用户信息* @return 权限信息*/Collection<SimpleGrantedAuthority> grantedAuthorities(Long userId);/**** @param userId 用户ID* @return RoleItemVOs*/List<RoleDTO> listByUserId(Long userId);void updateMenu(CeaMSysRoleDTO roleDTO, CeamSysRole role);
}

3、实现类

/*** <p>* 角色表 服务实现类* </p>** @author CeaM* @since 2023-01-28*/
@Slf4j
@Service
@AllArgsConstructor
public class CeamSysRoleServiceImpl extends ServiceImpl<CeamSysRoleMapper, CeamSysRole> implements ICeamSysRoleService {private ICeamSysMenuService ceamSysMenuService;private ICeamRoleMenuService ceamRoleMenuService;@Overridepublic IPage<CeaMSysRoleVO> pageCeaMSysRoleVO(PageableDTO pageable) {LambdaQueryWrapper<CeamSysRole> queryWrapper = Wrappers.<CeamSysRole>lambdaQuery().eq(CeamSysRole::getDeleted, GlobalConstants.FALSE);Page<CeamSysRole> page = new Page<>(pageable.getPage(), pageable.getSize());// 手动设置当前页，不然分页失效page.setCurrent((long)pageable.getPage() + GlobalConstants.ONE);Page<CeamSysRole> ceamSysRolePage = page(page, queryWrapper);IPage<CeaMSysRoleVO> ceaMSysRoleVOIPage = PageVOUtil.copyToPageVO(ceamSysRolePage, CeaMSysRoleVO.class);for (CeaMSysRoleVO role : ceaMSysRoleVOIPage.getRecords()) {List<MenuDTO> menuDTOS = ceamSysMenuService.findByRoleId(role.getId(), GlobalConstants.ZERO);role.setMenus(menuDTOS);}return ceaMSysRoleVOIPage;}@Overridepublic Collection<SimpleGrantedAuthority> grantedAuthorities(Long userId) {List<RoleDTO> roleItemDTOS = this.baseMapper.listByUserId(userId);if (CollectionUtils.isEmpty(roleItemDTOS)) {throw new ServiceException("没有分配角色");}List<MenuDTO> menuDTOS = ceamSysMenuService.findByRoles(roleItemDTOS, GlobalConstants.ZERO);// 角色Set<String> permissions = roleItemDTOS.stream().filter(role -> StringUtils.isNotBlank(role.getName())).map(RoleDTO::getName).collect(Collectors.toSet());permissions.addAll(menuDTOS.stream().filter(menu -> StringUtils.isNotBlank(menu.getPermission())).map(MenuDTO::getPermission).collect(Collectors.toSet()));return permissions.stream().map(SimpleGrantedAuthority::new).collect(Collectors.toList());}@Overridepublic List<RoleDTO> listByUserId(Long userId) {return this.baseMapper.listByUserId(userId);}@Overridepublic void updateMenu(CeaMSysRoleDTO roleDTO, CeamSysRole role) {if (roleDTO.getMenus().size() > 0) {List<CeamRoleMenu> rolesMenusList = roleDTO.getMenus().stream().map(i -> {CeamRoleMenu rolesMenus = new CeamRoleMenu();rolesMenus.setRoleId(roleDTO.getId());rolesMenus.setMenuId(i.getId());return rolesMenus;}).collect(Collectors.toList());ceamRoleMenuService.remove(new LambdaQueryWrapper<CeamRoleMenu>().eq(CeamRoleMenu::getRoleId, roleDTO.getId()));ceamRoleMenuService.saveBatch(rolesMenusList);}}
}
