使用generatorConfig配置，自动生成实体类，Mapper接口等

1.在项目的resource目录下面配置generatorConfig.properties文件，以及generatorConfig.xml文件

generatorConfig.properties文件中的主要配置信息为：

##需要修改为自己的mysql-connector-java-5.1.39.jar的地址

jdbc.driverLocation=E:\\Maven\\Repository\\mysql\\mysql-connector-java\\5.1.39\\mysql-connector-java-5.1.39.jar
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql://127.0.0.1:3306/databaseName?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC&autoReconnect=true&useSSL=false
jdbc.username=root
jdbc.password=******

generatorConfig.xml文件中的主要配置信息为：

<?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>
    <properties resource="generatorConfig.properties"></properties>

    <classPathEntry location="${jdbc.driverLocation}"></classPathEntry>

    <context id="default" targetRuntime="MyBatis3">
        <!--运行命令mybatis-generator:generate -->
        <commentGenerator>
            <!--去掉生成日期的注释 true：去掉配置-->
            <property name="suppressDate" value="true"></property>
            <!--去掉全部注释-->
            <property name="suppressAllComments" value="true"></property>
        </commentGenerator>

        <jdbcConnection
                driverClass="${jdbc.driverClass}"
                connectionURL="${jdbc.connectionURL}"
                userId="${jdbc.username}"
                password="${jdbc.password}">
        </jdbcConnection>

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

        <javaModelGenerator targetPackage="com.demo.bus.entity.projectEntity" targetProject="src/main/java">
            <property name="enableSubPackages" value="false"></property>
            <property name="constructorBased" value="true"></property>
            <property name="trimStrings" value="true"></property>
            <property name="immutable" value="false"></property>
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="mybatis.mapper.projectMapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"></property>
        </sqlMapGenerator>

        <javaClientGenerator targetPackage="com.demo.bus.mapper.projectMapper" targetProject="src/main/java" type="XMLMAPPER">
            <property name="enableSubPackages" value="true"></property>
        </javaClientGenerator>

        <!--附件上传，配置中心模块，审核中心模块，全国落地项目-->

        <table tableName="tableName(project)" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false" />

    </context>
</generatorConfiguration>

2.依赖的包org.mybatis.generator

<build>
        <plugins>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
            </plugin>
        </plugins>
    </build>

3.双击运行mybatis-generator包，包所在位置是对应项目的Plugins --> mybatis-generator

双击运行红色标注部分

4.查看log，检查对应的类以及接口是否生成成功

5.生成成功。
