先看pom.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

</dependency>

看起来没有什么问题，但是启动时会报错
Exception in thread "main" java.lang.NoSuchMethodError: 'org.springframework.core.io.support.SpringFactoriesLoader org.springframework.core.io.support.SpringFactoriesLoader.forDefaultResourceLocation(java.lang.ClassLoader)'

第一感觉是有冲突，代码的版本不兼容
换一种写法，
1，换dubbo的引入方式，放弃bom引入，单个引入
<!-- <dependencyManagement>-->

启动ok

2，去掉spring-boot-starter-parent 引入spring-boot-dependencies

启动ok
虽然版本都一样，但是不同的写法却有着不同的结果
具体原因没有去调查，但决定用第二种写法
