tomcat 启动的问题。

Question

maven项目下用的tomcat插件，启动后，访问地址为 Running war on http://localhost:8080/Musical，而不是正常的http://localhost:8080/ 这是为啥呢？是不是因为缺少配置呢？下面截图为pom.xml

全局搜索 Musical ，看在哪里配置了Musical 这个路径

Answer 3

解决办法，在配置插件的时候加入了configure属性

      <plugin>
        <groupId>org.apache.tomcat.maven</groupId>
        <artifactId>tomcat7-maven-plugin</artifactId>
        <version>2.1</version>
        <configuration>
          <path>/</path>
          <port>8080</port>
          <uriEncoding>UTF-8</uriEncoding>
          <server>tomcat7</server>
        </configuration>
      </plugin>

Answer 4

上面的 answer 表达得很清楚了；
通过日志，查看相关输出是哪个 maven 插件去执行的，比如 tomcat7-maven-plugin，然后去看看该插件的 Usage，基本可以解决问题。
