Intellij IDEA使用教程相关系列 目录

tomcat运行

步骤1：在pom.xml里添加插件代码

                        
				org.apache.tomcat.maven
				tomcat7-maven-plugin
				2.0
				
					8080
					UTF-8
					/bdcrpc
					tomcat
				
			

步骤2：点击刷新插件效果，在plugins里会出现tomcat插件

选择tomcat7-run运行

可以选择是正常运行和debug模式运行，右键tomcat7:run

启动成功。

一月 22, 2019 5:55:39 下午 org.apache.catalina.core.ContainerBase startInternal
严重: A child container failed during start
java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost]]
出现原因：tomcat插件和项目引用的jar冲突。都有包含tomcat-servlet-api.jar

解决方案：pom引用tomcat-servlet-api，添加scope，如下

			org.apache.tomcat
			tomcat-servlet-api
			7.0.64
