本文介绍了一个系统中企业及其部门信息的修改逻辑。企业信息可以被修改，前提是该企业未被注销；部门名称在所属企业内必须唯一。文章详细展示了Controller层与Service层的实现方式。

逻辑：

企业可重名，未被注销的企业都可以修改信息。
同一企业的部门不可重名，不同企业的部门可以重名。

Controller层：

企业：

    @PostMapping("/modify")
    public Result<CompanyVo> modifyCompany(@RequestParam Integer companyId,@RequestParam(required = false) String companyAddress) {

        Company company;
        company = companyService.getCompany(companyId);

        if (company != null) {

            if (companyService.getCompanyByDeletedAndId(companyId) != null){
                return Result.success(CompanyVo.setCompany(companyService.modifyCompany(companyId,companyAddress)));
            } else {
                return Result.error(ErrorEnum.ModifyCompanyError);
            }

        } else {
            return Result.error(ErrorEnum.CompanyNotExistError);
        }

    }

部门：

	@PostMapping("/modify")
    public Result<DepartmentVo> modify(@RequestParam Integer departmentId,@RequestParam String departmentName) {

        Department department ;
        department = departmentService.getDepartment(departmentId);

        if (department != null) {

            if (departmentService.getDepartmentByNameAndCompany(departmentName,department.getCompanyId()) == null){
                return Result.success(DepartmentVo.setDepartment(departmentService.modifyDepartmentInfo(departmentId,departmentName)));
            } else {
                return Result.error(ErrorEnum.ModifyDepartmentError);
            }

        } else {
            return Result.error(ErrorEnum.DepartmentNotExistError);
        }

    }

Service层：

企业：

@Override
    public Company modifyCompany(Integer companyId, String companyAddress) {
        Company company;
        company = companyRepository.findCompanyByIdAndDeletedFalse(companyId);
        company.setId(companyId);
        company.setCAddress(companyAddress);
        companyRepository.saveAndFlush(company);
        return company;
    }

部门：

	@Override
    public Department modifyDepartmentInfo(Integer departmentId,String departmentName) {

        Department department;
        department = departmentRepository.findDepartmentById(departmentId);
        department.setId(departmentId);
        department.setName(departmentName);
        departmentRepository.saveAndFlush(department);
        return department;

    }
