异常一:
java.net.BindException: Address already in use: bind
jvm 1 | 2017-10-18 15:08:10,792+0800 WARN [jetty-main-1] org.eclipse.jetty. util.component.AbstractLifeCycle - FAILED InstrumentedSelectChannelConnector@0.0 .0.0:8081: java.net.BindException: Address already in use: bind jvm 1 | java.net.BindException: Address already in use: bind
原因:端口号被占用,删掉端口号的进程。
异常二:
HTTP ERROR 500 :JSP support not configured
HTTP ERROR 500 Problem accessing /MavenView/index.jsp. Reason: JSP support not configured
在默认webapps下可以,但自定义的部署目录下就出现以上错误。原因是自定义的部署,没有添加jsp的module
默认的start.ini 下有个 --module=jsp
执行命令:java -jar ../start.jar --add-to-startd=jsp 即可在start.d下产生jsp.ini文件。
执行命令:java -jar ../start.jar 即可在网络上输出jsp文件。
如果是内置jetty服务插件,则缺少jsp的依赖:
