Mybatis框架的代码自动生成工具如何使用呢？

代码自动化生成的方式

Pom.xml 文件的修改
generatorConfig.xml 配置
配置运行命令参数

对于代码自动化生成，我们借助 maven 插件来实现 mybatis crud 基本代码的生成。

配置步骤如下:

1.Pom.xml 文件的修改

添加 mybatis 插件配置

<finalName>spring_mybatis</finalName> 

    <plugins> 

        <plugin> 

            <groupId>org.mybatis.generator</groupId> 

            <artifactId>mybatis-generator-maven-plugin</artifactId> 

            <version>1.3.2</version> 

            <configuration> 
        	<configurationFile>src/main/resources/generatorConfig.xml</configurationFile> 

                <verbose>true</verbose> 

                <overwrite>true</overwrite> 

            </configuration> 

        </plugin> 

    </plugins> 

</build>

2.generatorConfig.xml 配置

需添加到资源包下 src/mian/resources

<?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> 

    <!--数据库驱动--> 

    <classPathEntry location="D:/m2/repository/mysql/mysql-connector

    java/5.1.39/mysql-connector-java-5.1.39.jar"/> 

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

    <commentGenerator> 

    <property name="suppressDate" value="true"/> 

    <property name="suppressAllComments" value="true"/> 

    </commentGenerator> 

    <!--数据库链接地址账号密码--> 

    <jdbcConnection driverClass="com.mysql.jdbc.Driver"  

    connectionURL="jdbc:mysql://127.0.0.1:3306/mybatis" userId="root"  

    password="root"> 

    </jdbcConnection> 

    <javaTypeResolver> 

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

    </javaTypeResolver> 

    <!--生成 Model 类存放位置--> 

    <javaModelGenerator targetPackage="com.mage.po"  

    targetProject="D:/java/workspace_class_0523/spring_mybatis_02/src/main/java"> 

    <property name="enableSubPackages" value="true"/> 

    <property name="trimStrings" value="true"/> 

    </javaModelGenerator> 

    <!--生成映射文件存放位置--> 

    <sqlMapGenerator targetPackage="com.mage.mapper"  

    targetProject="D:/java/workspace_class_0523/spring_mybatis_02/src/main/java"> 

    <property name="enableSubPackages" value="true"/> 

    </sqlMapGenerator> 

    <!--生成 Dao 类存放位置--> 

    <javaClientGenerator type="XMLMAPPER" targetPackage="com.mage.dao"  

    targetProject="D:/java/workspace_class_0523/spring_mybatis_02/src/main/java"> 

    <property name="enableSubPackages" value="true"/> 

    </javaClientGenerator> 

    <table tableName="house" domainObjectName="House"

    enableCountByExample="false" enableUpdateByExample="false"  

    enableDeleteByExample="false" enableSelectByExample="false"  

    selectByExampleQueryId="false"></table> 

    </context> 

</generatorConfiguration>
