企业开发 2018-08-06 05:26:12 阅读次数: 0

本篇文章主要内容是介绍如何使用IDEA创建spring + SpringMVC + MyBatis的一个web项目，下面会给出项目搭建的详细步骤以及相关的配置文件。

一、创建一个项目工程

1.1 在File下拉->New -> project

1.2选择maven工程，勾选create from archetype，选择maven-archetype-webapp。netxt

1.3 填写groupid和artifactid。next

1.4设置maven home 。next

1.6 设置工程的jdk等

1.7 添加工程目录并设置工程目录属性，java目录为sources，resources的目录属性为resources

1.8 目录结构如下所示。
