mybatis-generator自动生成Model、Dao、mapper.xml文件

1. 在pom.xml文件中导入如下语句

   <!--        mybatis自动生成实体代码的插件-->
   <plugin>
       <groupId>org.mybatis.generator</groupId>
       <artifactId>mybatis-generator-maven-plugin</artifactId>
       <version>1.3.5</version>
       <dependencies>
           <dependency>
               <groupId>org.mybatis.generator</groupId>
               <artifactId>mybatis-generator-core</artifactId>
               <version>1.3.5</version>
           </dependency>
           <dependency>
               <groupId>mysql</groupId>
               <artifactId>mysql-connector-java</artifactId>
               <version>5.1.47</version>
           </dependency>
       </dependencies>
       <executions>
           <execution>
               <id>mybatis generator</id>
               <phase>package</phase>
               <goals>
                   <goal>generate</goal>
               </goals>
           </execution>
       </executions>
       <configuration>
           <!--            允许移动生成的文件-->
           <verbose>true</verbose>
           <!--            是否允许自动覆盖文件-->
           <overwrite>false</overwrite>
           <configurationFile>
               src/main/resources/mybatis-generator.xml
           </configurationFile>
       </configuration>
   </plugin>
   

2. 在resources文件夹下新建mybatis-generator.xml文件

   <?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>
   
       <context id="DB2Tables" targetRuntime="MyBatis3">
           <!--        数据库驱动、URL、账号密码-->
           <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                           connectionURL="jdbc:mysql://localhost:3306/miaosha"
                           userId="root"
                           password="123456">
           </jdbcConnection>
   
           <!--        生成DataObject（Domain）类存放位置-->
           <javaModelGenerator targetPackage="com.kenai.dataobject" targetProject="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="mapping"  targetProject="src/main/resources">
               <property name="enableSubPackages" value="true" />
           </sqlMapGenerator>
   
           <!--        生成dao类的存放位置-->
           <!--        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="ANNOTATEDMAPPER"：生成java model和基于注解的mapper对象-->
           <!--        type="MIXEDMAPPER"： 生成基于注解的java model和响应的mapper-->
           <!--        type="XMLMAPPER"：生成SQL Map XML文件和独立的mapper接口-->
           <javaClientGenerator type="XMLMAPPER" targetPackage="com.kenai.dao"  targetProject="src/main/java">
               <property name="enableSubPackages" value="true" />
           </javaClientGenerator>
   
           <!--        生成对应表及类名-->
           <table tableName="item" domainObjectName="ItemDO" enableCountByExample="false"
                  enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
                  selectByExampleQueryId="false"></table>
           <table tableName="item_stock" domainObjectName="ItemStockDO" enableCountByExample="false"
                  enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
                  selectByExampleQueryId="false"></table>
       </context>
   </generatorConfiguration>
   

3. 配置并执行(使用mvn mybatis-generator:generate命令执行也可以)
