Spring boot Mongo 更新：E11000 @Version 注释重复键错误

Question

我有一个带有 spring-data-mongodb (v3.0.0) 的 Spring boot (v2.3.0.RELEASE) 应用程序。

基本上，当我在文档中添加@Version注释时，当我尝试更新现有文档时应用程序会失败，代码如下：

我的文档如下：

    @Id
    private String paymentId;
    private String transactionId;
    private String transactionTypeCode;
    @Version
    private Integer version;

我的存储库如下：

public interface PaymentRepository extends MongoRepository<Payment, String>, PaymentRepositoryCustom {

       


}

更新失败的情况如下：

Optional<Payment> paymentSaved = Optional.ofNullable(paymentRepository.findMaxIdByRefer(request.getAdd().getRefer()));
populatePayment(paymentSaved, payment);
paymentRepository.save(payment);

public static void populatePayment( Optional<Payment> paymentSaved, Payment payment) {

    if (paymentSaved.isPresent() && !ObjectUtils.isEmpty(payment)) {
        payment.setTransactionId(paymentSaved.get().getTransactionId());
        payment.setCreationDate(paymentSaved.get().getCreationDate());
        payment.setPaymentId(paymentSaved.get().getPaymentId());
    }
}

应用程序在paymentRepository.save(payment)方法上失败，但出现以下异常：

org.springframework.dao.DuplicateKeyException: E11000 duplicate key error collection: test.payment index: _id_ dup key: { _id: ObjectId('627a35b7f1ea29549008487e') }; nested exception is com.mongodb.MongoWriteException: E11000 duplicate key error collection: test.payment index: _id_ dup key: { _id: ObjectId('627a35b7f1ea29549008487e') }

当我添加@Version注释时，它似乎正在尝试执行插入而不是更新，请问我如何解决此问题？

但是，我无法删除@Version注释。

Answer 1

我发现问题基本上在更新时版本为空，这就是为什么它试图创建新的付款而不是更新。我已经从数据库检索了版本，现在更新工作正常。
