mybatis-利用mybatis-generator(maven插件)自动生成代码

参考文章：https://www.cnblogs.com/yjmyzz/p/4210554.html

一、在pom.xml中添加plugin

<build>
<finalName>SSMDEMO</finalName>
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<configuration>
<configurationFile>src/main/resources/mybatis-generator/generatorConfig.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>1.3.2</version>
</dependency>
</dependencies>
</plugin>
</plugins>
<pluginManagement>
<plugins>
<!--This plugin's configuration is used to store Eclipse m2e settings
only. It has no influence on the Maven build itself. -->
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
<pluginExecutions>
<pluginExecution>
<pluginExecutionFilter>
<groupId>
org.mybatis.generator
</groupId>
<artifactId>
mybatis-generator-maven-plugin
</artifactId>
<versionRange>
[1.3.2,)
</versionRange>
<goals>
<goal>generate</goal>
</goals>
</pluginExecutionFilter>
<action>
<ignore></ignore>
</action>
</pluginExecution>
</pluginExecutions>
</lifecycleMappingMetadata>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>

二、编辑generatorConfig.xml配置文件

<?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>
<!-- 连接数据库jar包的路径 -->
<classPathEntry
location="D:/repository/mysql/mysql-connector-java/5.1.17/mysql-connector-java-5.1.17.jar" />
<context id="my" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="false" />
<property name="suppressAllComments" val
4000
ue="true" />
</commentGenerator>
<!-- 连接数据库属性配置 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/yeebi" userId="root"
password="123456" />
<!-- 生成实体类的配置 -->
<javaModelGenerator targetPackage="com.test.entity"
targetProject="D:/EcloudWorkSpase/SSMDEMO/src/test/java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- 生成实体类DAO(mapperDao)的配置 -->
<sqlMapGenerator targetPackage="com.test.entity"
targetProject="D:/EcloudWorkSpase/SSMDEMO/src/test/java">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- 生成mapper.xml的配置 -->
<javaClientGenerator targetPackage="com.test.entity"
targetProject="D:/EcloudWorkSpase/SSMDEMO/src/test/java" type="XMLMAPPER">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>

<!--<table tableName="T_FEE_AGTBILL" domainObjectName="FeeAgentBill" enableCountByExample="false"
enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false"/> -->
<!-- 所需要生成表的配置 ,如果有多个表，复制这一段，改下表名即可 -->
<table tableName="student" domainObjectName="FeeBase"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false">
<!--<columnRenamingRule searchString="^D_" replaceString=""/> -->
</table>

</context>
</generatorConfiguration>

三、使用方式

右击项目--->run as-->maven build

命令：mvn mybatis-generator:generate 或mybatis-generator:generate
