Mybatis自动生成Model与Mapper

neocai

　　使用Mybatis的Generator可以自动生成Model与Mapper，非常方便，只需要进行简单地配置即可
　　配置方式如下：

<?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>
<classPathEntry
location="mysql-connector-java-5.1.21.jar" />
<context id="DB2Tables" targetRuntime="MyBatis3">
<!--下面的配置使得生成的model中可以使用数据库中的Comment对字段进行注释-->
<commentGenerator>
<property name="suppressAllComments" value="false" />
</commentGenerator>
<!-- JDBC 连接信息 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/dbname" userId="root"
password="password">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<javaModelGenerator targetPackage="com.sdj.dao.model"
targetProject="../../../../java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<sqlMapGenerator targetPackage="com.sdj.dao.map"
targetProject="../../../../java">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!--ANNOTATEDMAPPER属性值使得生成的Mapper是Annotation的-->
<javaClientGenerator type="ANNOTATEDMAPPER"
targetPackage="com.sdj.dao.map" targetProject="../../../../java">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<table tableName="USER_ROLE" domainObjectName="UserRole"></table>
<!--useActualColumnNames属性使得生成的model中的属性与数据库表中的属性大小写一致-->
<table tableName="USER_INFO" domainObjectName="UserInfo"><property name="useActualColumnNames" value="true" /></table>
</context>
</generatorConfiguration>
