原因

引入错误的Maven依赖导致的，本来想的是引入的interface模块，没想到错误的导入了item模块，原因是接口模块不包含SpringBootApplication启动类，而item模块中有一个启动类，所以当使用SpringBootTest进行测试时，spring容器会自动扫描当前包下的所有类，查看有哪些类拥有@SpringBootApplication注解，而SpringBootApplication又带了@SpringBootConfiguration注解，所以就出现了发现多个@SpringBootConfiguration配置类而报错，只要引入正确的模块就好了，保证启动类的唯一性
