在SpringBoot项目中遇到报错信息，除了Error那一行的错误信息之外，也要看Caused by后面的报错的原因！！！
本报错信息中的
Cause by：BeanDefinitionStoreException: Failed to parse configuration class [com.sl.pay.PayApplication]; nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name ‘nativePayService’ for bean class [com.sl.pay.service.NativePayService] conflicts with existing, non-compatible bean definition of same name and class [com.sl.pay.lock.NativePayService]
**大概意思是说：**在项目/模块中有一个Bean对象有冲突，使得程序运行时不知道到底该选择哪个bean对应的实体类运行，这时候你要做的就是检查检查项目测试包test包中的类名中是否有和项目主体src包是否有相同的类名和类中的方法，如果有我所说的情况出现，然后解决问题，除此之外，另一种原因可能就是与项目中的配置类或者配置信息或者依赖的导入出错有关，然后依次检查解决问题！
