#### 项目结构 ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxODU3OTU1_size_16_color_FFFFFF_t_70_pic_center]  
项目路径可以自己定义，只要路径映射正确就可以

#### pom.xml ####

#### Emp.java，EmpMapper.java, EmpMapper.xml ####

[https://blog.csdn.net/qq\_41857955/article/details/102601180][https_blog.csdn.net_qq_41857955_article_details_102601180]

#### db.properties ####

# mysql
    jdbc.url=jdbc:mysql://localhost:3306/jektong?useUnicode=true&characterEncoding=utf-8
    jdbc.driver=com.mysql.jdbc.Driver
    jdbc.username=jektong
    jdbc.password=123456

这里的key值不能写url,driver,username,password,不然后面使用$\{url\},$\{username\}会报错
