***************************
APPLICATION FAILED TO START
***************************

Description:

The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

查看占用的端口的进程,根据被占用的端口号

netstat -alnp | grep 8080

查找到占用的端口的进程

[root@localhost usr]# netstat -alnp | grep 8080
tcp6       2      0 :::8080                 :::*                    LISTEN      1392/java           
tcp6       1      0 192.168.73.129:8080     192.168.73.1:52129      CLOSE_WAIT  -                   
tcp6     414      0 192.168.73.129:8080     192.168.73.1:52128      ESTABLISHED -

之后将查出的进程号删除

kill -9 1392(进程号)

删除成功

[root@localhost usr]# kill -9 1392
[1]+  已杀死

再启动就成功啦~

[root@localhost usr]# java -jar springdata-jpa-restfulcrud-0.0.1-SNAPSHOT.jar
