我创建了示例Spring-boot应用程序，它运行正常，没有任何错误，
现在，我想练习spring-retry重试某些方法。如果我不使用@EnableRetry，则我的应用程序启动时不会出现任何错误，但是重试不起作用。
如果我在配置类上使用@EnableRetry，则我的应用程序无法启动
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.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 ");
}
}

最佳答案
重试aspect dependencies，可以使用2个解决方案解决:
或者
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
</dependency>
关于java - Spring @EnableRetry引发InternalAutoProxyCreator，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/53699750/
