mybatis-generator有三种用法:命令行、eclipse插件、maven插件。个人觉得maven插件最方便,可以在eclipse/intellij idea等ide上可以通用。
现在使用的IDEA
1.随便找个springboot(最好了)的项目,更改POM.XML文件
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>
<configuration>
<!--配置文件的位置-->
<configurationFile>src/main/resources/geneno.xml</configurationFile>
<verbose>true</verbose>
<overwrite>true</overwrite>
</configuration>
<executions>
<execution>
<id>Generate MyBatis Artifacts</id>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.5</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
2.写好geneno.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>
<!--mysql 连接数据库jar 这里选择自己本地位置-->
<classPathEntry location="C:/Users/Bug_Yang/.m2/repository/mysql/mysql-connector-java/5.1.21/mysql-connector-java-5.1.21.jar" />
<context id="testTables" targetRuntime="MyBatis3">
<commentGenerator>
<!-- 是否去除自动生成的注释 true:是 : false:否 -->
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!--数据库连接的信息:驱动类、连接地址、用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://192.168.0.252:3306/ecloud_marketing" userId="root"
password="iloveyou2016,./">
</jdbcConnection>
<!-- 默认false,把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer,为 true时把JDBC DECIMAL 和
NUMERIC 类型解析为java.math.BigDecimal -->
<javaTypeResolver>
<property name="forceBigDecimals" value="true" />
</javaTypeResolver>
<!-- targetProject:生成PO类的位置 -->
<javaModelGenerator targetPackage="com.ecps.seckill.pojo"
targetProject="src/main/java">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="false" />
<!-- 从数据库返回的值被清理前后的空格 -->
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- targetProject:mapper映射文件生成的位置
如果maven工程只是单独的一个工程,targetProject="src/main/java"
若果maven工程是分模块的工程,targetProject="所属模块的名称",例如:
targetProject="ecps-manager-mapper",下同-->
<sqlMapGenerator targetPackage="com.ecps.seckill.mapper"
targetProject="src/main/java">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="false" />
</sqlMapGenerator>
<!-- targetPackage:mapper接口生成的位置 -->
<javaClientGenerator type="XMLMAPPER"
targetPackage="com.ecps.seckill.mapper"
targetProject="src/main/java">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="false" />
</javaClientGenerator>
<!-- 指定数据库表 -->
<table tableName="barter_group" domainObjectName="BarterGroup" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="barter_group_category" domainObjectName="BarterGroupCategory" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="barter_group_product" domainObjectName="BarterGroupProduct" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="barter_group_user" domainObjectName="BarterGroupUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="promotion_condition" domainObjectName="PromotionCondition" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="promotion_image" domainObjectName="PromotionImage" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="promotion_participant" domainObjectName="PromotionParticipant" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="promotion_participant_detail" domainObjectName="PromotionParticipantDetail" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="promotion_payway" domainObjectName="PromotionPayway" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>
geneno.xml的文件放在Resource的任何地方,只要在pom.xml的
plugni
里配置好可以
3.启动mvn的命令
4.生成的文件
