在IntelliJ中使用MBG

步骤如下：

1、创建一个Maven工程testMBG。

 

（2）编写pom.xml文件添加依赖

<?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>
    <properties resource="generator.properties"></properties>

    <!--指定特定数据库的jdbc驱动jar包的位置-->
    <classPathEntry location="${jdbc.driverLocation}"/>

    <context id="mysql" targetRuntime="MyBatis3">
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/mydb?useSSL=true"
                        userId="root"
                        password="123456">
        </jdbcConnection>

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

        <javaModelGenerator targetPackage="com.test.model" targetProject="\SpringDemo\testMBG\src\main\java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="com.test.xml"  targetProject="\SpringDemo\testMBG\src\main\java">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER" targetPackage="com.test.dao"  targetProject="\SpringDemo\testMBG\src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <table schema="mydb" tableName="student" domainObjectName="Student" >
        </table>

    </context>
</generatorConfiguration>

（3）在resource目录下增加generator.properties文件配置数据库驱动

jdbc.driverLocation=C:\\Users\\yinwe\\.m2\\repository\\mysql\\mysql-connector-java\\5.1.47\\mysql-connector-java-5.1.47.jar
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql://localhost:3306/mydb?useSSL=false
jdbc.userId=root
jdbc.password=123456

（4）在resource目录下增加generatorConfig.xml进行generator相关配置

<?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>
<properties resource="generator.properties"></properties>

<!--指定特定数据库的jdbc驱动jar包的位置-->
<classPathEntry location="${jdbc.driverLocation}"/>

<context id="mysql" targetRuntime="MyBatis3">
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                    connectionURL="jdbc:mysql://localhost:3306/mydb?useSSL=true"
                    userId="root"
                    password="123456">
    </jdbcConnection>

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

    <javaModelGenerator targetPackage="com.test.model" targetProject="\SpringDemo\testMBG\src\main\java">
        <property name="enableSubPackages" value="true" />
        <property name="trimStrings" value="true" />
    </javaModelGenerator>

    <sqlMapGenerator targetPackage="com.test.xml"  targetProject="\SpringDemo\testMBG\src\main\java">
        <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>

    <javaClientGenerator type="XMLMAPPER" targetPackage="com.test.dao"  targetProject="\SpringDemo\testMBG\src\main\java">
        <property name="enableSubPackages" value="true" />
    </javaClientGenerator>

    <table schema="mydb" tableName="student" domainObjectName="Student" >
    </table>

</context>
</generatorConfiguration>

（5）点击Run，点击Edit Configuration，点击+，双击Maven。出现如下页面：

在命令行输入mybatis-generator:generate，点击OK。

（6）运行Maven的generator。

（7）运行完成信息

 

（8）生成的目录及文件
