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;

    @GetMapping
    public 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;
 
    @Override
    public 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;
    }
 
    @Override
    public 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());
    }
 
    @Override
    public List<RoleDTO> listByUserId(Long userId) {
        return this.baseMapper.listByUserId(userId);
    }
 
    @Override
    public 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);
        }
    }
}
