Mybatis自动生成dao,mapping,model文件

相关步骤：

       1.下载mybatis-generator-core.zip包

       2.在将其解压后进入lib目录下   a.新建src文件夹（用于存放生成的文件）   b.新建generatorConfig.xml文件   c.将mysql-connector-java.jar添加进来

       3.桶过控制台进入下载的mybatis-generator-core文件夹下的lib目录下，使用命令：java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite即可生成相应代码。

generatorConfig.xml（生成的三个包的时候建议采用下面的.xml文件中的）：

<?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>    <!-- 数据库驱动-->        <classPathEntry  location="mysql-connector-java-5.1.39-bin.jar"/>        <context id="DB2Tables"  targetRuntime="MyBatis3">            <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>            <!--数据库链接URL，用户名、密码 -->            <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost/ssm" userId="root" password="">            </jdbcConnection>            <javaTypeResolver>                <property name="forceBigDecimals" value="false"/>            </javaTypeResolver>            <!-- 生成模型的包名和位置-->            <javaModelGenerator targetPackage="dqd.model" targetProject="src">                <property name="enableSubPackages" value="true"/>                <property name="trimStrings" value="true"/>            </javaModelGenerator>            <!-- 生成映射文件的包名和位置-->            <sqlMapGenerator targetPackage="dqd.mapping" targetProject="src">                <property name="enableSubPackages" value="true"/>            </sqlMapGenerator>            <!-- 生成DAO的包名和位置-->            <javaClientGenerator type="XMLMAPPER" targetPackage="dqd.dao" targetProject="src">                <property name="enableSubPackages" value="true"/>            </javaClientGenerator>        <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->            <table tableName="user_t" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>      </context>    </generatorConfiguration>
