直接上步骤：

(1) pom，添加tomcat7启动插件依赖，项目打方式设置为war包

            </plugin>
        </plugins>

    </build>
</project>

(2) 在IntelliJ IDEA集成Tomcat服务器

1，点击Run---EDit Configurations...

2.点击左侧“+”号，找到Tomcat Server---Local（若是没有找到Tomcat Server 可以点击最后一行 34 items more）

3.在Tomcat Server -> Unnamed -> Server -> Application server项目下，点击 Configuration ，找到本地 Tomcat 服务器，再点击 OK按钮。

(3) 配tomcat插件并启动

启动成功效果

还有一种启动方式

打开maven窗口，找的plugins插件中的tomcat7插件，在往下找到tomcat:run右键debug运行按钮也可以十分方便的启动项目
