Mybatis 反向生成 java代码 和 xml配置

首先在项目下创建 mbg.xml 文件

mbg.xml 内容如下：

<?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>
    <!-- 数据库驱动包位置 -->
    <!-- <classPathEntry location="H:\generator\oracle14.jar" /> -->
  <!--<classPathEntry location="H:\generator\mysql-connector-java-5.1.30.jar" />-->
    <context id="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <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:3306/four"
                        userId="ws"
                        password="1">
            <!-- <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:ORCL" userId="gqc" password="gqc"> -->

        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- 生成模型的包名和位置 -->
        <javaModelGenerator targetPackage="com.mr.model" targetProject="./src/main/java">
            <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.mr.mapper" targetProject="./src/main/resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <!-- 生成mapper的包名和位置 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.mr.mapper" targetProject="./src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        <!-- 要生成那些表(更改tableName和domainObjectName就可以) -->
        <table tableName="t_goods" domainObjectName="Goods" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />

    </context>
</generatorConfiguration>

更改内容如下 1

创建 MybatisTest类 内容如下：

public static void main(String[] args) throws Exception{
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        //指向逆向工程配置文件，只需要把下面这个文件改为你自己写的配置文件即可
        File configFile = new File("mbg.xml");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);
    }

运行上方代码即可 生成
