按照[http://www.cnblogs.com/hackyo/p/6646051.html][http_www.cnblogs.com_hackyo_p_6646051.html]来搭建ssm框架，一步成功，特此记录一下。

本机环境：

*  idea2017.3
 *  jdk1.8
 *  mysql5.5
 *  maven3.3.9

# 步骤： #

## 1. idea新建maven webapp项目 ##

## 2. 搭建项目结构 ##

按照该目录结构创建好相应的文件

搭建时有两个点需要注意一下（针对idea新手）：

（1）新建的目录用途需要设置一下，否则新建时无class文件的选项

![1001990-20180626212556738-1364941979.png][]

（2）有的文件类型没有配置（如xml）,所以需要在idea中配置一下模板

## 3. 配置配置文件内容 ##

新建测试类进行测试

    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    // 加载spring配置文件
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration({
         "classpath:spring-mybatis.xml"})
    public class IUserDaoTest {
    
        @Autowired
        private IUserDao dao;
    
        @Test
        public void testSelectUser() throws Exception {
            long id = 1;
            User user = dao.selectUser(id);
            System.out.println(user.getUsername());
        }
    }
