整体目录结构:
其中包下全部是采用mybatis自动生成工具生成。
mybatis自动生成文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
<generatorConfiguration>
<!--加载属性文件 -->
<properties resource="db.properties" />
<context id="context1">
<commentGenerator>
<property name="suppressDate" value="true" />
<!-- 是否去除自动生成的注释 true:是 : false:否 -->
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!-- 数据库连接URL,用户名,密码 -->
<jdbcConnection driverClass="${jdbc.driver}" connectionURL="${jdbc.url}" userId="${jdbc.username}" password="${jdbc.password}" />
<!--生成模型的包名和位置 -->
<javaModelGenerator targetPackage="mybatisGenerator.rawMode" targetProject="orderManage2/src" />
<!--映射文件的包名和位置 -->
<sqlMapGenerator targetPackage="mybatisGenerator.rawMapper" targetProject="orderManage2/src" />
<!--DAO的包名和位置 -->
<javaClientGenerator targetPackage="mybatisGenerator.rawMapper" targetProject="orderManage2/src" type="XMLMAPPER" />
<!--要生成哪些表 -->
<table schema="" tableName="user" domainObjectName="RawUser" enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false" />
<table schema="" tableName="goods" domainObjectName="RawGoods" enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false" />
<table schema="" tableName="orders" domainObjectName="RawOrders" enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false" />
<table schema="" tableName="address" domainObjectName="RawAddress" enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false" />
</context>
</generatorConfiguration>
为了方便以后数据库的修改以及需求修改等因素,我觉得应该把所有的自动生成的代码放进一个包中,然后在外边继承它里边的东西。这样方便以后重新自动生成,又不会影响我们自己手动编写的部分。
config包下全部为配置文件。
SqlMapConfig.xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
