mybatis-generator-core自動生成do、mapping、dao 代碼

---

使用mybatis配置映射文件，有點麻煩，容易出錯，能夠使用jar工具自動生成代碼，即高效又方便

1、下載兩個jar，並放置在G:\tool\maven\generator目錄下（本身定義）

mybatis-generator-core-1.3.2.jar

mysql-connector-java-5.1.34.jar

2、創建do表

user_info 表，id，name，password

3、配置 generator.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>
    <!-- 數據庫驅動包位置 -->
    <classPathEntry location="G:\tool\maven\generator\mysql-connector-java-5.1.34.jar" />

    <context id="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!-- 數據庫連接URL、用戶名、密碼 -->
         <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/testdb" userId="root" password="root"> 
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- 生成模型的包名和位置 -->
        <javaModelGenerator targetPackage="com.yuanmeng.springdemo.model" targetProject="G:\tool\maven\generator\src">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- 生成的映射文件包名和位置 -->
        <sqlMapGenerator targetPackage="com.yuanmeng.springdemo.mapping" targetProject="G:\tool\maven\generator\src">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.yuanmeng.springdemo.dao" targetProject="G:\tool\maven\generator\src">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        <!-- 要生成那些表(更改tableName和domainObjectName就能夠) -->
        <table tableName="user_info" domainObjectName="UserInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
    </context>
</generatorConfiguration>

 

4、進入G:\tool\maven\generator下，執行命令java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml –overwrite 便可生成代碼
