java - Spring Retryable注解ClassNotFoundException

Question

我想为 restTemplate 使用 @Retryable 注释。我添加了:

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

以及 @EnableRetry 到配置类。我已经标记方法:

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

与(在新线程中)

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

但我从 catalina 收到错误消息:

我做错了什么？

已编辑:我向前移动了一点。发现Spring Retry makes use of AOP所以我补充说:

<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>

现在我得到了不同的错误:

为了隔离问题，我创建了小型 springMVC 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 mvn dependency:tree 的输出:

它在添加 spring-boot-starter-aop 依赖项 后对我有用，如下所示:

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