Mybatis generator配置（超详细）

MyBatis Generator (MBG) 是一个 MyBatis 的代码生成器，它可以自动生成包括Mapper接口、Mapper XML文件以及实体类的代码。以下是一个简单的配置示例，用于生成基于一个特定数据库表的MyBatis映射代码。

1. 在项目的pom.xml中添加MyBatis Generator依赖：

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.4.0</version>
    <dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.23</version>
        </dependency>
    </dependencies>
</plugin>

2. 创建generatorConfig.xml配置文件，配置数据库连接、表信息以及生成的目标路径等：

<?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>
 
    <context id="MysqlContext" targetRuntime="MyBatis3">
 
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
 
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/mydatabase"
                        userId="myUsername"
                        password="myPassword">
        </jdbcConnection>
 
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
 
        <javaModelGenerator targetPackage="com.example.model" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
 
        <sqlMapGenerator targetPackage="com.example.mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
 
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.example.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
 
        <table tableName="user" domainObjectName="User" enableCountByExa
