JPA 存储库上的 Spring Retry

Sum*_*man 5 java jpa spring-retry spring-boot

我是 spring 的新手,作为项目实现的一部分,我应该在调用 JPA 存储库的服务方法上添加 spring 重试。代码如下所示

@Retryable(value = {Exception.class},maxAttempts = 1,backoff = @Backoff(300))
public Page<Account> findAllAccounts(AccountSearchRequest account, Pageable pageable) {
    try {
        return map(accountSearchRepository.findAll(account, pageable));
    }catch (Exception e){
        System.out.println("SQL EXCEPTION CAUGTH!!!!!!!!!");
    }
    return null;
}
@Recover
public void recover(Exception e){
    System.out.println("!!!!!!!!!!!Failed to get connection!!!!!!");
}

数据库:Postgresql,

应用程序:Java Spring Boot(公开 Rest API 以获取所有帐户)

HikariPool 最大池大小 ** : **1

Hikari 连接超时 ** : **1000

JMeter 用于发送10,000 个API 请求。

问题:我能够看到SQL EXCEPTION CAUGTH!!!!!!!!! 打印,但我认为重试不起作用,因为我没有看到恢复方法的打印。我错过了什么吗?

下面是gradle依赖项

感谢您的支持。

我发现问题是该@Recover方法的数据类型与@Retryable. 上述场景中Retry工作的条件

@Recover并且@Retryable应该是公共的并且具有相同的返回类型

尝试

@Retryable(value = {SQLException.class},maxAttempts = 1,backoff = @Backoff(300))
public Page<Account> findAllAccounts(AccountSearchRequest account, Pageable pageable) throws SQLException {    
       throw new SQLException("test");
}

@Recover
public void recover(Exception e){
    System.out.println("!!!!!!!!!!!Failed to get connection!!!!!!");
}
