Mybatis 自動生成程式碼的外掛使用方法

1、下載Mybatis的jar包外掛
mybatis-generator-core-1.3.2.jar

2、下載資料庫驅動
本例子中採用mysql資料庫
mysql-connector-java-5.1.18.jar

3、配置檔案 generatorConfig.xml

<?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>
    <!--資料庫驅動-->
    <classPathEntry    location="mysql-connector-java-5.1.18.jar"/>
    <context id="DB2Tables"    targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property
 
 name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--資料庫連結地址賬號密碼-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://ip:port/db?characterEncoding=UTF-8" userId="xxx" password="xxx">
        </jdbcConnection>
        <javaTypeResolver
 
>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!--生成Model類存放位置-->
        <javaModelGenerator targetPackage="com.jd.notice.domain.common" targetProject="src">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!--生成對映檔案存放位置-->
        <sqlMapGenerator targetPackage="notice.mapping" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!--生成Dao類存放位置-->
        <!--<javaClientGenerator type="XMLMAPPER" targetPackage="lcw.dao" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>-->
        <!--生成對應表及類名-->
        <table tableName="notice_message_record" domainObjectName="NoticeMessageRecord" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
                <table tableName="notice_message_template" domainObjectName="NoticeMessageTemplate" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
                        <table tableName="notice_business_apply" domainObjectName="NoticeBusinessApply" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

4、執行java命令生成程式碼

java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite

ps：intellij外掛iBATIS/MyBatis
mini-plugin 可以讓我們從dao層直接直接點選到對應的xml,很方便快捷。
