java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder

搭建SpringCloud报SpringApplicationBuilder错误

后来在网上查找了一些资料，发现是pom依赖的问题，然后我就降级了springboot版本
修改前的pom.xml

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.7.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>

修改后的pom.xml

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>

问题解决，大家如果想更深入了解，可以去spring官网查看一下对应版本的依赖！
