java - Spring @EnableRetry 抛出 InternalAutoProxyCreator

Question

我创建了示例 Spring-boot 应用程序，它运行良好，没有任何错误，

现在我想练习spring-retry来重试一些方法。如果我不使用 @EnableRetry，我的应用程序启动时没有任何错误，但重试不起作用。

如果我在配置类上使用@EnableRetry，我的应用程序将无法启动

build.gradle

apply plugin: 'java-library'

repositories {
  jcenter()
  }

 dependencies {

        // https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-web
         compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '2.1.0.RELEASE'
        // https://mvnrepository.com/artifact/org.springframework.kafka/spring-kafka
         compile group: 'org.springframework.kafka', name: 'spring-kafka', version: '2.2.0.RELEASE'
        // https://mvnrepository.com/artifact/commons-logging/commons-logging
         compile group: 'commons-logging', name: 'commons-logging', version: '1.2'
         // https://mvnrepository.com/artifact/org.springframework.retry/spring-retry
         compile group: 'org.springframework.retry', name: 'spring-retry', version: '1.2.0.RELEASE'

}

配置

import org.springframework.context.annotation.Configuration;
import org.springframework.retry.annotation.EnableRetry;

@Configuration
@EnableRetry
public class RetryConfig {

 }

重试服务

@Service
public class RetryService {

 @Retryable(value = { CustomException.class },  maxAttempts = 2, backoff = @Backoff(delay=1000))
 public Optional<String> requestOne(int value){
    if(value ==1) {
        throw new CustomException();
    }
    return Optional.of(" request one method");
}

@Retryable(value = { CustomException.class },  maxAttempts = 2, backoff = @Backoff(delay=1000))
public Optional<Integer> requestTwo(int value){
    if(value ==1) {
        throw new CustomException();
    }
    return Optional.of(1);
}

@Recover
public Optional<String> recovery(CustomException ex, int value){
    return Optional.of(" recovery method ");
  }

}

Answer 1

重试期待aspect dependencies使用 2 个解决方案解决:

including spring-boot-starter-aop solved this for me and ensured versioning compatibility with the rest of Spring Boot.

或者

add the following dependency into my pom:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-aspects</artifactId>
</dependency>
