Summary of Spring IO issues

1. Spring boot embedded Tomcat does not start: unregistering jmx-exposed beans on shutdown

  在官网(http://start.spring.io/)上generate project，将生成的项目导入idea中，运行之后控制台输出“Unregistering JMX-exposed beans on shutdown”，

     tomcat也没有运行。寻找原因，看了下pom.xml文件中tomcat依赖关系如下：


<dependency>        <groupId>org.springframework.boot</groupId>        <artifactId> Spring-boot-starter-tomcat</artifactid>        <scope>provided</scope></dependency>

Leave <scope>provided</scope> commented out and rerun the project to launch the embedded Tomcat server: Tomcat started on port (s): 8080 (http)

If not, in the introduction of the Web package:

<dependency>        <groupId>org.springframework.boot</groupId>        <artifactId> Spring-boot-starter-web</artifactid></dependency>
