Java 使用Spring DataCouchbase处理瞬态异常

我有一个非常简单的Spring Boot应用程序，它从外部系统接收数据并将其保存到Couchbase。我正在尝试处理这样一个场景：我的应用程序遇到与数据库的临时连接问题

我正在使用Couchbase 6.0和

spring data Couchbase

version

3.1.2。在我的应用程序中发布

，并尝试使用

CustomExceptionClassifierRetryPolicy

实现

RetryTemplate

，如下所示：

retryTemplate.setRetryPolicy(new CustomExceptionClassifierRetryPolicy());

下面是my

CustomExceptionClassifierRetryPolicy的实现

public class CustomExceptionClassifierRetryPolicy extends ExceptionClassifierRetryPolicy {
private static final long serialVersionUID = 1L;

public CustomExceptionClassifierRetryPolicy() {
    final AlwaysRetryPolicy alwaysRetryPolicy = new AlwaysRetryPolicy();
    this.setExceptionClassifier(new Classifier<Throwable, RetryPolicy>() {
        @Override
        public RetryPolicy classify(Throwable classifiable) {
            if (classifiable.getCause() instanceof TransientDataAccessException) {
                return alwaysRetryPolicy;
            }
            return new NeverRetryPolicy();
        }
    });
}

我原以为为
org.springframework.dao.TransientDataAccessException
exception定义一个重试策略可以解决我的问题，但这似乎有帮助

有人能告诉我如何处理应用程序中所有与网络相关的临时问题，并采用重试机制吗
