mybatis generator 使用方法

环境: ubuntu   eclipse maven

一. 简介

mybatis-geneator是一款mybatis自动代码生成工具，可以通过配置，快速生成mapper和xml文件以及pojo

二.配置

pom.xml配置

 <dependencies>
<dependency>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-core</artifactId>
    <version>1.3.7</version>
</dependency>
  </dependencies>

<build>
        <finalName>shop</finalName>
        <plugins>
        <plugin>
          <groupId>org.mybatis.generator</groupId>
          <artifactId>mybatis-generator-maven-plugin</artifactId>
          <version>1.3.7</version>
           <configuration>
    <verbose>true</verbose>
    <overwrite>true</overwrite>
    </configuration>
        </plugin>
</plugin>
</plugins>
</build>

在main的resource目录下创建generatorConfig.xml文件

generatorConfig.xml配置

<?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">

        </commentGenerator>

        </javaModelGenerator>
          <!--map xml生成器 --> 
        <sqlMapGenerator targetPackage="com.feilong.shop.dao.mappers"
                         targetProject="./src/main/java">

        </sqlMapGenerator>

        <table tableName="shop_user" domainObjectName="User" >
          <!-- 如果设置为true，生成的model类会直接使用column本身的名字，而不会再使用驼峰命名方法，比如BORN_DATE，生成的属性名字就是BORN_DATE,而不会是bornDate -->
        <property name="useActualColumnNames" value="true"/>
        </table>
          <table tableName="shop_address" domainObjectName="Address" >
               <property name="useActualColumnNames" value="true"/>
        </table>

               <property name="useActualColumnNames" value="true"/>
        </table>
        
    </context>
</generatorConfiguration>

三. 生成文件

linux控制台在项目pom.xml配置文件的同级目录下输入

mvn mybatis-generator:generate
