javaweb项目

项目步骤

先创建maven的工程

1.导包

java蓝色包和resource资源的包

2.在web.xml中修改新版文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                         http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0"
         metadata-complete="true">
</web-app>

3.pome中删除只剩下

  <modelVersion>4.0.0</modelVersion>
  <packaging>war</packaging>

  <name>javaweb-session-cookie</name>
  <groupId>org.example</groupId>
  <artifactId>javaweb-session-cookie</artifactId>
  <version>1.0-SNAPSHOT</version>

4.pome中导包

      <groupId>javax.servlet</groupId>
