创建springbootdemo后运行报MongoSocketOpenException错误解决方法
在类SpringbootdemoApplication上右键Run as选择Spring Boot App后Console输出报错日志如下:

上网百度,找到一篇文章说原因是springboot自动配置了支持mongodb。在启动springboot时会自动实例化一个mongo实例,需要禁用自动配置 ,
增加@SpringBootApplication(exclude = MongoAutoConfiguration.class)这个注解即可,原文链接为http://blog.csdn.net/xuyw10000/article/details/72918360。
我增加在类上增加注解后,这个错误解决了,但是输出了新的错误日志,如下:
java.lang.ClassCastException: org.springframework.boot.context.event.ApplicationFailedEvent cannot be cast to org.springframework.boot.web.context.WebServerInitializedEvent

复制第一行错误日志,在谷歌上搜索答案,需要该项目的pom.xml文件注释Mongo相关的启动语句,如下:
<!-- <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency> -->
保存后重新启动,不会再报错。在github原文链接为:https://github.com/spring-projects/spring-boot/issues/10047。
