前言

主要是启动异常，开发完一个业务需求之后发现，居然有一个bean启动异常，提示的信息真的让人摸到头脑，这个到底是什么原因导致的这个异常错误，不可思议！

异常信息，应用启动异常截图

目前我启动的应用在测试环境的报错信息如下。很少见，启动的时候提示的。

主要得报错信息

No qualifying bean of type 'com.alibaba.dubbo.config.ApplicationConfig' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations:

明显提示的是config的配置已经实例化了，导致注入失败，而不能继续加载后面的配置项！

猜测原因

实例化类是，zk部署在一台服务器，Service调用重名但是却部署到了俩台服务器导致同一个API，俩台服务器依赖调用，同时是服务名相同，但是项目名称不一样导致！

改动，实例化类的名称进行修改掉，比如此处的：【name 'dupNewsController'】暂时性的还是后续报错！

应该是缓存没有清空！

解决办法步骤

1、清除zk里面的data目录，里面文件很大，然后重启原来zk依赖的应用的服务；

2、确定应用起来的仅有一台服务占用一个端口，发现有俩个应用启动导致依赖错乱；

3、注释掉提示报错的bean，然后重新mvn -clean install，重新运行；

然后解决！不在有类似的提示。

其他解决办法：

启动的时候注入实例化，手动的进行配置，避免二次注入的时候因为bean重复名称注入失败！

这个方法我另外一个同事是这么解决的，我的不是。然后放在这里作为一个备注，如果可以叠话，你们可以尝试一下。重要的代码如下

import com.alibaba.dubbo.config.ApplicationConfig;
import com.datadevelopment.middle.auth.common.ShiroConstant;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@Slf4j
@SpringBootApplication(scanBasePackages = {ShiroConstant.AUTH_PACKAGE, "com.datadevelopment.npp"})
public class NppWebApplication {public static void main(String[] args) {try {// 应用配置信息ApplicationConfig application = new ApplicationConfig("news-production-platform-web");// 版本号application.setVersion("2021.10.27.1");// 负责人application.setOwner("loveyouforever");// 组织名称application.setOrganization("test_organization");// 环境application.setEnvironment("test");// 字节码编译器application.setCompiler("javassist");SpringApplication.run(NppWebApplication.class, args);log.info("the service npp-web started!");log.error("正常启动完成");} catch (Exception e) {log.error("the service npp-web start failed, the exception: {}", e);}}}

还有把应用名称在项目中进行配置 YML

application:name: news-production-platform-web

spring:profiles:include: daoredis:database: 0host: 127.0.0.1port: 6379timeout: 3000jedis:pool:max-active: -1max-wait: -1max-idle: 8min-idle: 3application:name: news-production-platform-web

然后maven-install上传到xshell之后运行目前是正常的：

启动命令：

nohup java -Xms512m -Xmx512m -Xrunjdwp:transport=dt_socket,address=9013,server=y,suspend=n -jar /home/program/npp/npp-web/npp*.jar > /home/program/npp/npp-web/log/npp.log 2>&1 &
