Mybatis generator 配置入门

Mybatis generator 插件的使用可以大大提高我们开发的效率,可根据数据库快速生成 实体类,mapper文件以及对应的

xml映射文件。

配置方法:

第一步:

在SpringBoot的pom文件的插件配置中添加如下配置:

<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.7</version>
     <!--generator生成配置覆盖重写文件-->
    <configuration>
    <overwrite>true</overwrite>
    </configuration>
 </plugin>

第二步:

下载jar包:

mysql-connector-java-5.1.6.jar

第三步:

参考Mybatis Generator 配置详解文章
https://www.imooc.com/article/21444

在resources目录下新建generator配置文件generatorConfig.xml:

<?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>
<!--    运行系统下的的绝对路径-->
    <classPathEntry location="D:\WorkSpace\IdeaSpace\mysql-connector-java-5.1.6.jar" />

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

<!--        不再追加xml内容-->
        <plugin type="org.mybatis.generator.plugins.UnmergeableXmlMappersPlugin" />

<!--        配置不生成备注-->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1:3306/mimall?characterEncoding=utf-8"
                        userId="root"
                        password="root">
        </jdbcConnection>

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

        <javaModelGenerator targetPackage="cn.blogsx.mimall.pojo" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
<!--            <property name="trimStrings" value="true" />-->
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="mappers"  targetProject="src/main/resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER" targetPackage="cn.blogsx.mimall.dao"  targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <table tableName="mall_order" domainObjectName="Order"  enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/>
<!--        <table tableName="mall_order" domainObjectName="Order" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/>-->
        <table tableName="mall_order_item" domainObjectName="OrderItem" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/>


    </context>
</generatorConfiguration>

配置完成后即可在终端输入如下命令生成相应的文件:

mvn mybatis-generator:generate
