mybatis反向工程配置（命令行方式）

使用步驟，step1.將兩個jar包和配置文件config.xml 放到同一個目錄下；step2.修改配置文件中的數據庫連接和表名；step3運行命令。齊活。文末有彩蛋

1. 命令java -jar mybatis-generator-core-1.3.7.jar -configfile config.xml
2. jar包2個

• https://repo1.maven.org/maven2/org/mybatis/generator/mybatis-generator-core/1.3.7/mybatis-generator-core-1.3.7.jar
• https://repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.46/mysql-connector-java-5.1.46.jar

3. 配置文件，名稱爲config.xml，需要修改數據庫連接和表名

<?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-5.1.46.jar"/>
    <context id="Mybatis3Context" targetRuntime="MyBatis3">
        <property name="javaFileEncoding" value="UTF-8"/>
        <!-- 1/2 修改數據庫鏈接 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/test"
                        userId="root"
                        password="123456">
        </jdbcConnection>

        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <javaModelGenerator targetPackage="model" targetProject="./codes">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="mapperxml" targetProject="./codes">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER" targetPackage="mapper" targetProject="./codes">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!-- 2/2 修改表名 -->
        <table tableName="table2"  enableCountByExample="false"
               enableDeleteByExample="false" enableUpdateByExample="false" enableSelectByExample="false">
        </table>
        <table tableName="table1"  enableCountByExample="false"
               enableDeleteByExample="false" enableUpdateByExample="false" enableSelectByExample="false">
        </table>
    </context>
</generatorConfiguration>
