当启动tomcat时候出现
Server Tomcat v8.0 Server at localhost was unable to start within 45 seconds. If the server requires more time, try increasing the timeout in the server editor. 的错误,那表示你的tomcat启动超时了,有时候你重新启动下就好了,但有时需要重新启动很多次,如果你不想这样的话,你只需修改下tomcat的启动 时间就行了,步骤如下:
修改 workspace\.metadata\.plugins\org.eclipse.wst.server.core\servers.xml文件。
<servers>
<server hostname="localhost" id="JBoss v5.0 at localhost" name="JBoss v5.0 at localhost" runtime-id="JBoss v5.0" server-type="org.eclipse.jst.server.generic.jboss5" server-type-id="org.eclipse.jst.server.generic.jboss5" start-timeout="1000" stop- timeout="15" timestamp="0">
<map jndiPort="1099" key="generic_server_instance_properties" port="8090" serverAddress="127.0.0.1" serverConfig="default"/>
</server>
</servers>
把 start-timeout="45" 改为 start-timeout="1000" 或者更长 重启eclipse就可以了。
