弹簧可重试注释类不成立异常

java spring spring-boot spring-retry

2022-09-03 13:08:40

我想对 .我添加了：@RetryablerestTemplate

<dependency>
       <groupId>org.springframework.retry</groupId>
       <artifactId>spring-retry</artifactId>
       <version>1.2.1.RELEASE</version>
</dependency>

以及配置类。我已经标记了方法：@EnableRetry

restTemplate.exchange(url, HttpMethod.POST, request, String.class);

与（在新线程中）

@Retryable(maxAttempts=4,value=Exception.class,backoff=@Backoff(delay = 2000))

但是我从卡塔利娜那里得到了错误：

我做错了什么？

编辑：我向前移动了一点。发现Spring Retry利用了AOP，所以我添加了：

<dependency>
  <groupid>org.springframework</groupid>
  <artifactid>spring-aop</artifactid>
  <version>4.2.5.RELEASE</version>
</dependency>
<dependency>
  <groupId>org.aspectj</groupId>
  <artifactId>aspectjweaver</artifactId>
  <version>1.8.8</version>
</dependency>

现在我得到不同的错误：

为了隔离问题，我创建了小项目，它是一样的。为了保持一切简单，只使用了很少的依赖项。这是从以下位置输出的：springMVCmvn dependency:tree

答案 1

在添加了spring-boot-starter-aop依赖项后，它对我有用，如下所示：

compile ("org.springframework.boot:spring-boot-starter-aop:1.5.10.RELEASE")

答案 2

我会回答我自己的问题，因为它现在似乎正在工作。所有必需的依赖项：

<dependency>
    <groupId>org.springframework.retry</groupId>
    <artifactId>spring-retry</artifactId>
    <version>1.2.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aop</artifactId>
    <version>4.3.11.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.8.10</version>
</dependency>

检查是否存在重复的依赖关系（例如，通过，必要时使用）。确保使用修饰配置类。出于某种原因，您需要将调用方与方法本身分开。例如：mvn dependency:tree<exclusions>@EnableRetry

@Retryable(maxAttempts = 4, value = {ResourceAccessException.class}, backoff = @Backoff(delay = 5000))
public ResponseEntity<String> tryToSendAndReturnResponseByRestTemplate(final RestTemplate restTemplate,
                                                                       final HttpEntity<MyObjDTO>
                                                                               request) {

    return restTemplate.exchange(resolveUrl(ENDPOINT_ADDRESS), HttpMethod.POST, request, String.class);
}

转到标记为 f.e 的类。并在不同的类别中 f.e. 您调用的类：SenderManager@ServicePhoneDirector

senderManager.tryToSendAndReturnResponseByRestTemplate(restTemplate, request);

它应该有效。（如果需要指定在尝试（仅在此处）后仍遇到异常时应返回的内容，则可以创建另一个标记为的方法（在类中），如下所示：4SenderManager@Recover

@Recover
public ResponseEntity<String> recoverWhenSendingMessageFailed(final ResourceAccessException e) {
    return new ResponseEntity<>(e.getMessage(), HttpStatus.REQUEST_TIMEOUT);
}

但是，如果您需要来自（in method）的args，请记住，参数是从失败方法的参数列表中填充的，其顺序与失败的方法相同，并且具有相同的返回类型@Retryable@Recover
