Spring boot adds mybatis generator to automatically generate code

Create a generatorConfig.xml file (the file directory src/main/resources/generator/ corresponds to the plugin configurationFile node configuration in the pom.xml file)

<?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">

    <context id="DB2Tables"  targetRuntime="MyBatis3">

            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 生成模型的包名和位置-->
        <javaModelGenerator targetPackage="com.winter.model" targetProject="src/main/java">

Add the following configuration to the plugins node in pom.xml. 

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.5</version>
    <dependencies>
        <!--配置这个依赖主要是为了等下在配置mybatis-generator.xml的时候可以不用配置classPathEntry这样的一个属性，避免代码的耦合度太高-->

            <artifactId>mysql-connector-java</artifactId>
