MyBatis Generator的簡單使用方法示例

在項目resource目錄下創建mybatis-generator文件夾

在文件夾下創建generatorConfig.xml，配置需要生成代碼的數據表

<?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> <properties resource='mybatis-generator/generator.properties'/> <!-- 連接數據庫jar包的路徑--> <!--<classPathEntry location='d:/java/JavaTools/mysql-connector-java-5.1.48/mysql-connector-java-5.1.48-bin.jar'/>--> <context targetRuntime='MyBatis3'> <commentGenerator> <property name='suppressDate' value='true'/> <!-- 是否去除自動生成的注釋 true：是 ： false:否 --> <property name='suppressAllComments' value='true'/> </commentGenerator> <!--數據庫連接參數 --> <jdbcConnection driverClass='${driverClassName}' connectionURL='${url}' userId='${username}' password='${password}'> </jdbcConnection> <javaTypeResolver> <property name='forceBigDecimals' value='false'/> </javaTypeResolver> <!-- 實體類的包名和存放路徑 --> <javaModelGenerator targetPackage='com.shop.order.bean' targetProject='src/main/java'> <property name='enableSubPackages' value='true'/> <property name='trimStrings' value='true'/> </javaModelGenerator> <!-- 生成映射文件*.xml的位置--> <sqlMapGenerator targetPackage='mapper' targetProject='src/main/resources'> <property name='enableSubPackages' value='true'/> </sqlMapGenerator> <!-- 生成DAO的包名和位置 --> <javaClientGenerator type='XMLMAPPER' targetPackage='com.shop.order.mapper' targetProject='src/main/java'> <property name='enableSubPackages' value='true'/> </javaClientGenerator> <!-- tableName：數據庫中的表名或視圖名；domainObjectName：生成的實體類的類名--> <table tableName='book' domainObjectName='Book' enableCountByExample='false' enableUpdateByExample='false' enableDeleteByExample='false' enableSelectByExample='false' selectByExampleQueryId='false'/> <!-- 可以添加多個需要生產代碼的實體--> <!-- <table tableName='xxx' domainObjectName='xxx' enableCountByExample='false' enableUpdateByExample='false' enableDeleteByExample='false' enableSelectByExample='false' selectByExampleQueryId='false'/> ... <table tableName='xxx' domainObjectName='xxx' enableCountByExample='false' enableUpdateByExample='false' enableDeleteByExample='false' enableSelectByExample='false' selectByExampleQueryId='false'/> --> </context></generatorConfiguration>

在文件夾下創建generator.properties配置文件

driverClassName=com.mysql.jdbc.Driverurl=jdbc:mysql://localhost:3306/store?useUnicode=true&characterEncoding=UTF-8&relaxAutoCommit=true&zeroDateTimeBehavior=convertToNullusername=rootpassword=root配置Maven

pom.xml中引入依賴

<build> <plugins> <plugin><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.5</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>1.3.5</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency></dependencies> </plugin> </plugins> </build>執行Maven插件

雙擊運行mybatis-generator:generate

控制臺輸出結果，生產mapper和bean文件
