我在尝试添加新员工时遇到此错误。无法提交 JPA 事务；嵌套异常是 javax.persistence.RollbackException: Error while committing the transaction 提交事务时出错] 的根本原因 java.lang.UnsupportedOperationException: null

   @RequestMapping(
        method = RequestMethod.POST,
        value = "addEmployeeDetails",
        produces = MediaType.APPLICATION_JSON_VALUE,
        consumes = (MediaType.APPLICATION_JSON_VALUE))
    public String addEmployeeDetails (
        @RequestBody final EmployeeDTO empDTO) throws ReEncryptionException
    {
        log.info("In AddEmployeeDetails().");
        return reEncryptionService.addEmployeeDetails(empDTO);
    }


   @Transactional
    public String addEmployeeDetails (final EmployeeDTO employeeDTO) throws ReEncryptionException
    {
            final Employee emp = Employee.builder()
                .empName(employeeDTO.getEmpName())
                .creditCardNumber(employeeDTO.getCreditCardNumber())
                .accountNumber(employeeDTO.getAccountNumber())
                .tenantId(employeeDTO.getTenantId())
                .build();
            emp.setEmpAddress(Arrays.asList(
                new Address(11, "abohar"),
                new Address(22, "Bangalore")));
