config客户端启动总是报空指针异常

     试便各种方法终无解决，把“StatelessRetryOperationsInterceptorFactoryBean”源码读了一遍也没有找到解决问题的办法。对着“Fetching config from server at : http://127.0.0.1:6030/”一直发愣想。自我对话后得到解决：

经验：难道是config服务端没有启动（其实已经启动服务了而且是正常的很）

自己：已经启动了

经验：提示信息“Fetching config from server at : http://127.0.0.1:6030/”像是在说config客户端无法连接的服务端，是不是yml配置文件问题呀！

spring:
  cloud:
    config:
      #  Config Server 地址，有如下两种方式：
      # 1. 采用直接访问config服务的方式
      # uri: http://127.0.0.1:6030
      # 2. 采用服务注册中心的服务id
      discovery:
        enabled: true
        service-id: service-config
      # 配置文件的{application}部分
      name: service-a
      # 配置文件的{profile}
      profile: dev
      # gitde 分支
      label: rewloc
      #是否启动快速失败功能，功能开启则优先判断config server是否正常（必须放到bootstrap文件中）
      fail-fast: true

自己：于是乎，把上面的配置文件检查了N遍后，没有发现任务配置上的问题。

经验：看到“org.springframework.retry.interceptor.RetryOperationsInterceptor$ItemRecovererCallback.recover(RetryOperationsInterceptor.java:141)”提示，难道是自定义“RetryConfiguration”类没有加载，看到这个类的时候发现在类名上面怎么没有“@Configuration”注解，给这个类加上注解试试吧！

package com.ztf.service.a.config;

import org.springframework.amqp.rabbit.config.RetryInterceptorBuilder;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.retry.interceptor.RetryOperationsInterceptor;

/**

public class RetryConfiguration {

    /**

     * @return spring cloud config的超时、重试操作的配置类

     */
    @Bean
    @ConditionalOnMissingBean(name = "configServerRetryInterceptor")
    public RetryOperationsInterceptor configServerRetryInterceptor() {
        return RetryInterceptorBuilder.stateless()
                //#最初重试间隔为 1000 毫秒 #每次重试失败后，重试间隔所增加的倍数 #最长重试间隔为 5000 毫秒
                .backOffOptions(1000, 1.2, 5000)
                //#最多重试 10 次
                .maxAttempts(10)
                .build();
    }
}

自己：“RetryConfiguration”这个类不是在“/resources/META-INF/spring.factories"文件中配置过了吗？

org.springframework.cloud.bootstrap.BootstrapConfiguration=com.ztf.service.a.config.RetryConfiguration

经验：对呀！！！根据提示我能肯定是config客户端连接不上config服务端

自己：我还是去看看config服务端服务吧！config服务端就一个启动类，有什么问题呀！

2020-11-27

经验：是不是启动类出问题了，比如没有加载config服务之类的。

package com.ztf.config;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;

/**
 * 类描述：配置中心服务启动类
 *
 * @author Rewloc
 * @version 1.0
 * @email luhaopeng2005@126.com
 * @date 2020/8/21 17:43
 * @since JDK 14
 */
@SpringBootApplication
public class ConfigApplication {

    /**
     * 功能描述: 程序入口
     *
     * @param args 参数
     * @auther 鲁浩鹏  Lu Haopeng
     * @date 2020/8/21 17:54
     */
    public static void main(String[] args) {
        SpringApplication.run(ConfigApplication.class, args);
    }
}

自己：这个启动类和其他微服务启动类没有上面区别呀！还是上网看看吧！CSDN、百度、码云、开源中国中寻找良药。在一篇博客中偶尔看到需要在启动类上面加上“@EnableConfigServer”注解，病重乱投医，加上试一下吧！启动config服务端，在启动config客户端，哇塞！不报错了！

@EnableConfigServer注解作用

        从字面意思上不难理解，该注解是配置config服务标识的注解类。根据我个人经验得知，这个注解是将spring cloud中的微服务标识成config服务端的注解，如果不加上此注解那么spring cloud config就没有服务端，当其客户端启动时由于需要检测config服务端是否活着而报上面（最上面）的错误信息。

求打赏安慰
