> Mybatis-Generator是一个用于自动生成dao层接口、pojo以及mapper xml的一个Mybatis插件。

**1、在工程中的pom.xml文件，配置如下依赖及插件**

<plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
        <configuration>
            <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
            <verbose>true</verbose>
            <overwrite>true</overwrite>
        </configuration>
    </plugin>

**2、在main的resource目录下创建generatorConfig.xml文件**

<?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="D:/tools/myRepository/mysql/mysql-connector-java/8.0.13/mysql-connector-java-8.0.13.jar" />
    
        <context id="default" targetRuntime="MyBatis3">
            <commentGenerator>
                <property name="suppressDate" value="true" />
                
                <property name="suppressAllComments" value="true" />
            </commentGenerator>
    
            
            <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/mydb" userId="root" password="root">
            </jdbcConnection>
    
            
            <javaTypeResolver>
                <property name="forceBigDecimals" value="false" />
            </javaTypeResolver>
    
            
            <javaModelGenerator targetPackage="generator" targetProject="./src/main/java">
                
                <property name="enableSubPackages" value="true" />
                
                <property name="trimStrings" value="true" />
            </javaModelGenerator>
    
            
            <sqlMapGenerator targetPackage="generator" targetProject="./src/main/resources">
                
                <property name="enableSubPackages" value="true" />
            </sqlMapGenerator>
    
            
            <javaClientGenerator type="XMLMAPPER" targetPackage="generator" targetProject="./src/main/resources">
                
                <property name="enableSubPackages" value="true" />
            </javaClientGenerator>
    
            <table tableName="tb_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false">
            </table>
        </context>
    </generatorConfiguration>

**3、使用maven运行插件，自动生成代码**
