tomcat运行

异常处理

--------------------

# tomcat运行 #

步骤1：在pom.xml里添加插件代码

<plugin>
    				<groupId>org.apache.tomcat.maven</groupId>
    				<artifactId>tomcat7-maven-plugin</artifactId>
    				<version>2.0</version>
    				<configuration>
    					<port>8080</port>
    					<uriEncoding>UTF-8</uriEncoding>
    					<path>/bdcrpc</path>
    					<server>tomcat</server>
    				</configuration>
    			</plugin>

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。

异常1：

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

<dependency>
    			<groupId>org.apache.tomcat</groupId>
    			<artifactId>tomcat-servlet-api</artifactId>
    			<version>7.0.64</version>
    			<scope>provided</scope>
    </dependency>
