Spring Boot启动报错 :ApplicationEventMulticaster not initialized - call 'refresh'

一、问题描述

Spring-boot项目一启动就报错:

java.lang.IllegalStateException: ApplicationEventMulticaster not initialized - call 'refresh' before multicasting events via the context: org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@10617a1: startup date [Fri May 11 19:04:42 CST 2018]; root of context hierarchy

二、解决方法

问题就出在:

Caused by: org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'loggingServiceImpl' for bean class [com.xxxx.cloud.service.logging.impl.LoggingServiceImpl] conflicts with existing

纯在冲突。进入与现有冲突，该类如下:

@Service
public class LoggingServiceImpl implements LoggingService {

    @Override
    public void logPrint(String logStr) {

    }
}

后来一想，好像引入的jar包也有这个类，而且是通过@Service注入进来的。。将文件重命名就行了。
