1. 利用mybatis反向工程generatorSqlmapCustom完成对数据库十表的映射

generatorConfig.xml

 1 <?xml version="1.0" encoding="UTF-8"?>

27             <property name="enableSubPackages" value="false" />
28             <!-- 从数据库返回的值被清理前后的空格 -->

41             <!-- enableSubPackages:是否让schema作为包的后缀 -->
42             <property name="enableSubPackages" value="false" />

54         <table schema="" tableName="checks"></table>
55     </context>
56 </generatorConfiguration>

2. 配置mybatis

SqlMapperConfig.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE configuration
 3         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
