最优雅地整合 Spring & Spring MVC & MyBatis 搭建 Java 企业级应用(附源码)

最优雅地整合 Spring & Spring MVC & MyBatis 搭建 Java 企业级应用(附源码)

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

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

@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。
