mybatis 自动生成代码

 

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-3-generator-config_1_0.dtd" >
<generatorConfiguration>

    <!-- 本地数据库驱动程序jar包的全路径 -->
    <classPathEntry location="C:\Users\\tl19638\\.m2\\repository\\mysql\\mysql-connector-java\\8.0.12\\mysql-connector-java-8.0.12.jar"/>
    <context id="context" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="false"/>
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <!-- 数据库的相关配置 -->
        <jdbcConnection
                driverClass="com.mysql.cj.jdbc.Driver"
                connectionURL="jdbc:mysql://localhost:3306/springmvc?useSSL=false&amp;serverTimezone=Hongkong&amp;characterEncoding=utf-8&amp;autoReconnect=true"
                userId="root"
                password="123456"/>

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

        <!-- 实体类生成的位置 -->
        <javaModelGenerator
                targetPackage="com.xc.mybatis.entity"
                targetProject=".\src\main\java">
            <property name="enableSubPackages" value="false"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- *Mapper.xml 文件的位置  sqlMapGenerator-->
        <sqlMapGenerator
                targetPackage="mapper"
                targetProject=".\src\main\resources">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- Mapper 接口文件的位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.xc.mybatis.mapper"
                             targetProject=".\src\main\java">
            <property name="enableSubPackages" value="false"/>
        </javaClientGenerator>

        <!-- 相关表的配置 -->

        <table tableName="tb_area"/>
    </context>
</generatorConfiguration>

需要改一些内容:

  1. 本地数据库驱动程序jar包的全路径(必须要改)。
  2. 数据库的相关配置(必须要改
  3. 相关表的配置(必须要改
  4. 实体类生成存放的位置。
  5. MapperXML 生成文件存放的位置。
  6. Mapper 接口存放的位置。
