Spring Retryable annotation ClassNotFoundException

It worked for me after adding the spring-boot-starter-aop dependency like below:

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

I will answer my own question 'cause it seems to be working now. All dependencies that are necessary:

<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>

check if there is no duplicate dependencies (f.e. by mvn dependency:tree, use <exclusions> where necessary). Be sure you decorated your config class with @EnableRetry. For some reason you need to separate the caller from the method itself. F.e.this:

@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);}

goes to SenderManager class marked as f.e. @Service and in a different class f.e. PhoneDirector class you call:

senderManager.tryToSendAndReturnResponseByRestTemplate(restTemplate, request);

It should work. (If you need to specify what supposed to be returned if after 4 (only here) attempts you're still getting an exception, you can create another method (in SenderManager class) marked with @Recover, like this:

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

But If you needed args from @Retryable (in @Recover method) remeber that arguments are populated from the argument list of the failed method in the same order as the failed method, and with the same return type

spring-retry uses spring aop, make sure you have aop added in your pom and try clean building the application.

for spring app :

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

for spring boot :

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