springboot中使用mybatis generator自动生成代码

1.创建maven项目，在pom.xml文件中添加依赖下载mybatis generator，

		<!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core -->
		<dependency>
			<groupId>org.mybatis.generator</groupId>
			<artifactId>mybatis-generator-core</artifactId>
			<version>1.3.7</version>
		</dependency>
		<build>
		<plugins>
			<plugin>
				<groupId>org.mybatis.generator</groupId>
				<artifactId>mybatis-generator-maven-plugin</artifactId>
				<version>1.3.7</version>
			</plugin>
		</plugins>
	</build>

mybatis generator 的版本可从 https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core 这里查看获取

2.generatorConfig.xml配置文件

generatorConfig.xml配置文件的配置内容可以直接从官网下载 http://www.mybatis.org/generator/configreference/xmlconfig.html

<?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>
    <!--数据库驱动包路径-->
    <classPathEntry
            location="C:\Users\xxx\.m2\repository\mysql\mysql-connector-java\5.1.45\mysql-connector-java-5.1.45.jar"/>

    <context id="DB2Tables" targetRuntime="MyBatis3">
        <!-- 注释 -->
        <commentGenerator>
            <!-- 是否取消注释 -->
            <property name="suppressAllComments" value="true"/>
            <!-- 是否生成注释代时间戳-->
            <property name="suppressDate" value="true"/>
        </commentGenerator>

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/test"
                        userId="root"
                        password="******"> <!-- 数据库密码-->
        </jdbcConnection>

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

        <!--类对象-->
        <javaModelGenerator targetPackage="com.shinena.example.model" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!--mapper xml文件路径-->
        <sqlMapGenerator targetPackage="mybatis.mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        
        <!-- XMLMAPPER -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.shinena.example.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <table tableName="user" domainObjectName="UserModel"
        ></table>

    </context>
</generatorConfiguration>

配置信息可以查看官方文档

3，生成代码

1）使用 intellij idea，如下图，输入命令 mybatis-generator:generate 执行即可。
2）如果ecplise中使用，则右击工程，maven build，添加命令mybatis-generator:generate
