Java Spring可检索注释类NotFoundException

我想使用

@Retryable

注释

restmplate

。我补充说：

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

（在新的线程中）

但我从catalina那里得到了错误：

我会回答我自己的问题，因为它现在似乎起作用了。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>

转到标记为f.e.

@Service的
SenderManager
类，并在您调用的不同类f.e.
PhoneDirector
类中：

senderManager.tryToSendAndReturnResponseByRestTemplate(restTemplate, request);

它应该会起作用。（如果您需要指定在
4
（仅此处）尝试后仍获得异常时应返回的内容，则可以创建另一个方法（在
SenderManager
类中），该方法标记为
@Recover
，如下所示：

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

@Recover
public ResponseEntity Recoverwhen SendingMessage失败（最终资源访问异常e）{
返回新的响应属性（例如getMessage（），HttpStatus.REQUEST\u TIMEOUT）；
} 

但是如果您需要
@Retryable
（在
@Recover
方法中）中的参数，请记住，
在添加spring boot starter aop依赖项后，它对我有效，如下所示：

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

SpringRetry使用SpringAOP，确保在pom中添加了aop，然后尝试干净地构建应用程序

对于spring应用程序：

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-aop</artifactId>
   <version>4.1.4.RELEASE</version>
</dependency>


org.springframework

对于弹簧靴：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
    <version>2.0.3.RELEASE</version>
</dependency>


org.springframework.boot
弹簧启动机aop

你在Catalina中添加了jar吗？
aspectjrt-1.7.3.jar
？如果你接受你的答案，那就太好了。这个问题似乎还没有正确的答案。这很有效，但我只使用了aspectjweaver，没有aop。
@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);
}

senderManager.tryToSendAndReturnResponseByRestTemplate(restTemplate, request);

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