IDEA使用 MyBatis-generator 自动生成 MyBatis

1、IDEA创建maven工程

2、 在maven项目的pom.xml 添加mybatis-generator-maven-plugin 插件和MySQL数据库驱动依赖

<dependencies>
        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            <version>5.1.34version>
        dependency>
    dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.mybatis.generatorgroupId>
                <artifactId>mybatis-generator-maven-pluginartifactId>
                <version>1.3.5version>
                <configuration>
                    <verbose>trueverbose>
                    <overwrite>trueoverwrite>
                configuration>
            plugin>
        plugins>
    build>

3、在maven项目下的src/main/resources 目录下建立名为 generatorConfig.xml的配置文件，作为mybatis-generator-maven-plugin 插件的执行目标，模板如下：

<?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>
    

    <classPathEntry location="/Users/youname/Documents/soft/repository/mysql/mysql-connector-java/5.1.34/mysql-connector-java-5.1.34.jar" />

    <context id="mysql_tables" targetRuntime="MyBatis3">
        
        <commentGenerator>
            <property name="suppressAllComments" value="true" />
            <property name="suppressDate" value="true" />
        commentGenerator>

        
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1:3306/test?characterEncoding=UTF-8"
                        userId="root"
                        password="123456">
        jdbcConnection>

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

        
        <javaModelGenerator targetPackage="com.test.domain" targetProject="src">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        javaModelGenerator>

        
        <sqlMapGenerator targetPackage="com.test.mapper"  targetProject="src">
            <property name="enableSubPackages" value="true" />
        sqlMapGenerator>

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

        
        <table schema="test" tableName="user" domainObjectName="user"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
        table>

    context>
generatorConfiguration>

 4、使用maven运行mybatis-generator-maven-plugin插件：工程名->Plugins->mybatis-generator->mybatis-generator:generate->Run Maven Build

ok，接下来就看到生成的文件了。
