使用方法

1、引包

<dependency>
  <groupId>org.springframework.retry</groupId>
  <artifactId>spring-retry</artifactId>
 </dependency>
 
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
    <version>2.6.3</version>
</dependency>

2、启动类增加开启重试机制的注解

@SpringBootApplication
@EnableAsync
@EnableRetry
public class CorporaHelperApplication {

    public static void main(String[] args) {
        SpringApplication.run(CorporaHelperApplication.class, args);
    }

}

3、在需要重试的方法上添加@Retryable重试注解

    @Retryable(value = Exception.class, maxAttempts = 3, backoff = @Backoff(delay = 1000, multiplier = 1.5))
    public ResponseEntity accessMachineTranslation(MTTranslateReqVo vo) throws Exception {
