Spring 安装facet的目的是什么；jst.web“；在org.eclipse.wst.common.project.facet.core.xml中

每当我将maven项目导入Eclipse时，就会得到facet jst.web的版本2.3。我必须手动更改此文件（通过右键单击project>project>choose 3.1 for Dynamic Web Module进行更改不允许我单击应用）

虽然这似乎是一个小问题，但我必须多次这样做，否则，我会正确地执行“mvn clean compile”，但当我右键单击服务器并尝试添加应用程序时，我会看到它错过了spring-web-x.x.x.jar，显然应用程序已部署，但根本无法工作

org.eclipse.wst.common.project.facet.core.xml

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="jst.web" version="2.3"/> <!-- I always have to change here to reflect javax.servlet-api version from my pom -->
  <installed facet="wst.jsdt.web" version="1.0"/>
  <installed facet="java" version="1.7"/>
</faceted-project>
