Spring重试支持Spring Retry的方法

本文介绍了Spring重试支持Spring Retry的方法，分享给大家，具体如下：

第一步、引入maven依赖

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>1.5.3.RELEASE</version>

</parent>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.retry</groupId>

<artifactId>spring-retry</artifactId>

<version>1.1.2.RELEASE</version>

</dependency>

<dependency>

<groupId>org.aspectj</groupId>

<artifactId>aspectjweaver</artifactId>

<version>1.8.6</version>

</dependency>

第二步、添加@Retryable和@Recover注解

package hello;

import org.springframework.remoting.RemoteAccessException;

import org.springframework.retry.annotation.Backoff;

import org.springframework.retry.annotation.Recover;

import org.springframework.retry.annotation.Retryable;

import org.springframework.stereotype.Service;

@Service

public class RemoteService {

@Retryable(value= {RemoteAccessException.class},maxAttempts = 3,backoff = @Backoff(delay = 5000l,multiplier = 1))

public void call() throws Exception {

System.out.println("do something...");

throw new RemoteAccessException("RPC调用异常");

}

@Recover

public void recover(RemoteAccessException e) {

System.out.println(e.getMessage());

}

@Retryable注解
被注解的方法发生异常时会重试
value:指定发生的异常进行重试
include:和value一样，默认空，当exclude也为空时，所有异常都重试
exclude:指定异常不重试，默认空，当include也为空时，所有异常都重试
maxAttemps:重试次数，默认3
backoff:重试补偿机制，默认没有
