说明：

生成实体类配置

<!-- 模型文件 -->
<javaModelGenerator targetPackage="cn.tiger.smartsign.entity"
targetProject="SmartSign20140326/src">
<property name="enableSubPackages" value="false" />
<!-- 当为true时，产生的代码文件将按照schema产生子文件夹 -->
<property name="trimStrings" value="true" />
<!-- set变量时自动剔除空白 -->
</javaModelGenerator>

生成映射器xml文件配置

<!-- 模型文件 -->
<javaModelGenerator targetPackage="cn.tiger.smartsign.entity"
targetProject="SmartSign20140326/src">
<property name="enableSubPackages" value="false" />
<!-- 当为true时，产生的代码文件将按照schema产生子文件夹 -->
<property name="trimStrings" value="true" />
<!-- set变量时自动剔除空白 -->
</javaModelGenerator>

生成mapper接口

<!-- XML映射文件 -->
<sqlMapGenerator targetPackage="cn.tiger.smartsign.xml"
targetProject="SmartSign20140326/src">
<property name="enableSubPackages" value="false" />
</sqlMapGenerator>

数据库表配置

<!-- 数据库表 -->
<table schema="SmartRoad" tableName="users" domainObjectName="Users"
enableCountByExample="false"
enableUpdateByExample="false"
enableDeleteByExample="false"
enableSelectByExample="false"
selectByExampleQueryId="false"
>
<property name="useActualColumnNames" value="false" />
</table>

设置不生成Example类

enableCountByExample="false" 

enableUpdateByExample="false"

enableDeleteByExample="false"

enableSelectByExample="false"

selectByExampleQueryId="false"
