我为Java Spring使用什么主类？

Question

我正在尝试使用提供的MVC Spring Project模板从SpringToolSuite创建JAR或WAR文件。当我尝试导出（通过STS）或干净的包（maven）我的代码时，由于找不到主清单属性，因此jar始终无法运行。在模板项目中没有提供main（）的类。该项目在我设置的Pivotal tc服务器实例上的 STS内运行。当我尝试将项目导出为JAR时，问题就出现了。

这是我的项目的pom.xml：

Answer 1

Web项目（战争），不能只保存为罐子。但是，当你在使用Spring时，我建议你看看Spring Boot：http://projects.spring.io/spring-boot/

Spring Boot允许你创建web项目作为可运行jar。

另一种选择是：http://tomcat.apache.org/maven-plugin-trunk/executable-war-jar.html

这个插件允许你建立一个独立的罐子了Web项目的，由包装的Tomcat的独立版本放进瓶子里。
