文件目录文件结构

文件结构

右击创建mave

选择 Mave Project 点击Next

点击Next

选择webapp

填写完成后点击Finish

完成后会有src/main/java , src/main/resources, src/test/java, src/test/resources中的包不全的情况,如果不全手工新建不全的包即可，如果补全没有识别，右击项目build path 选择C....之后AddFolder就好了

完成后会出现错误：The superclass “javax.servlet.http.HttpServlet” was not found on the Java Build Path index.jsp /MavenDemo/src/main/webapp line 1 JSP Problem*

解决办法：BuildPath添加service library位于tomcat目录下lib中的servlet-api.jar即可
