Spring工程搭建

创建Maven项目

1.下载Maven资源包

　　http://maven.apache.org/download.cgi

2.打开IDEA创建Maven项目

　　在新建项目窗口选择Maven项目：检查当前SDK版本是否为最新版本。

配置Maven

1.修改Maven home directory的路径

• File——Settings...打开设置

• 搜索Maven
• 改路径

搭建配置引入依赖：

• Maven仓库查询链接：mvnrepository

刷新Maven

代码截屏：

1.接口类

2.实现类

3.实现接口

4.测试类的方法

5.测试结果

步骤：

1、新建UserService接口

2、新建UserService实现类

3、通过bean将UserService放入容器

4、通过context的getbean方法拿到UserService对象
