这里使用 Maven
项目管理工具构建项目
初始化项目
- 打开 Intellij IDEA,点击
Create New Project
- 选择 Maven 构建项目
- 选择 JDK 版本
选择 maven-archetype-webapp
模板(Java Web
项目)
填写项目在 Maven 仓库中的坐标(在 Maven 仓库中根据这个坐标才能找到该项目)
- 选择 Maven 路径
- 选择 Maven 配置文件路径
- 选择 Maven 本地仓库路径
- 填写项目名
- 选择工作目录
创建目录
在 src
> main
目录下分别新建 java
源码目录 和 resource
配置文件目录
java
目录下创建基本的源码目录结构
webapp
目录下创建 static
目录,用于存放静态资源文件(css, js, img 等)
webapp
> WEB-INF
目录下创建 views
目录,用于存放视图页面(jsp, html 等)
pom.xml
完整的 pom.xml
配置如下

创建访问视图
在 webapp
> WEB-INF
> views
目录下新建 index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Index</title> </head> <body> <h1> Hello SSM </h1> </body> </html>
在 controller
目录下创建 IndexController
类
package com.antoniopeng.hello.ssm.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class IndexController { @RequestMapping(value = "/") public String index() { return "index"; } }
部署到 Tomcat 服务器
点击 Intellij IDEA
右上方 Add Configuration..
添加 Tomcat 本地服务器配置
配置下载好的 Tomcat 服务器
Tomcat8 官网下载地址
设置访问端口号,默认 8080
将项目添加到 Tomcat 服务器
最后运行项目,访问 http://localhost:8080/ 即可。
