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 --><classPathEntrylocation="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" value="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
