mybatis逆向工程IDEA版本

mybatis逆向工程IDEA版本

准备工作

1. pom.xml文件引入相关插件

 <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>

2. 添加配置文件

•  generator.properties

【jdbc.driverLocation】的路径为真实jar包路径
jdbc.driverLocation=D:\\software\\mvnrepository\\mysql\\mysql-connector-java\\5.1.6\\mysql-connector-java-5.1.6.jar
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql:///zsxt
jdbc.userId=root
jdbc.password=root

•  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>
    <!--导入属性配置-->
    <properties resource="generator.properties"></properties>

    <!--指定特定数据库的jdbc驱动jar包的位置-->
    <classPathEntry location="${jdbc.driverLocation}"/>

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

        <!-- optional，旨在创建class时，对注释进行控制 -->
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <!--jdbc的数据库连接 -->
        <jdbcConnection
                driverClass="${jdbc.driverClass}"
                connectionURL="${jdbc.connectionURL}"
                userId="${jdbc.userId}"
                password="${jdbc.password}">
        </jdbcConnection>


        <!-- 非必需，类型处理器，在数据库类型和java类型之间的转换控制-->

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


        <!-- Model模型生成器,用来生成含有主键key的类，记录类 以及查询Example类
            targetPackage     指定生成的model生成所在的包名
            targetProject     指定在该项目下所在的路径
        -->
        <javaModelGenerator targetPackage="com.xlisteven.generator.model"
                            targetProject="src/main/java">

            <property name="trimStrings" value="true"/>
            <!-- 建立的Model对象是否 不可改变  即生成的Model对象不会有 setter方法，只有构造方法 -->
            <property name="immutable" value="false"/>
        </javaModelGenerator>

        <!--Mapper映射文件生成所在的目录 为每一个数据库的表生成对应的SqlMap文件 -->
        <sqlMapGenerator targetPackage="com.xlisteven.generator.mapper"
                         targetProject="src/main/java">
            <property name="enableSubPackages" value="false"/>
        </sqlMapGenerator>

        <!-- 客户端代码，生成易于使用的针对Model对象和XML配置文件 的代码

                type="MIXEDMAPPER",生成基于注解的Java Model 和相应的Mapper对象
                type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口

        </javaClientGenerator>


        <table tableName="reguser" domainObjectName="User"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"

</generatorConfiguration>

3. 添加测试数据库
