IntelliJ Java编辑.jsp无服务器重新启动

Question

我是一个前端的web开发人员，我得到了一个Java项目，我的任务是开发前端.jsp文件(html / css / js)。

我已经在IntelliJ社区版本15中设置了该项目，并且使用Maven运行良好：

mvn -Denv=local tomcat7:run-war

编译只需1分30秒，等待这么长时间才能看到一个简单的CSS / HTML更改，这是令人沮丧的。

我被告知，使用IntelliJ可以以一种方式设置它，这样我就可以编辑.jsp文件并动态查看更改，而无需重新启动tomcat。

但是怎么做呢？(您可能已经猜到了，我对Java / Maven /Tomcat知之甚少)

IntelliJ中的Maven窗口如下所示：

还有一个POM文件：

Answer 1

问题是“跑步战争”的目标被利用了。它运行该应用程序的“打包”版本。试着跑：

tomcat7:run

(安装"run-war“-这只是您所显示的窗口中的一个目标) IntelliJ中的Maven窗口如下所示

您还可能需要将此添加到pom.xml中的依赖项中。

 <dependency>
     <groupId>javax.servlet</groupId>
     <artifactId>servlet-api</artifactId>
     <version>2.5</version>
     <scope>provided</scope>
 </dependency>

这已经完成了我的工作:现在我可以轻松地编辑html / css / js文件(动态)，而不需要经常性的tomcat重新启动和重新部署。
