MyBatis Generator的簡單使用方法示例
添加配置文件
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 id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <!-- 是否去除自動生成的註釋 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.Driver url=jdbc:mysql://localhost:3306/store?useUnicode=true&characterEncoding=UTF-8&relaxAutoCommit=true&zeroDateTimeBehavior=convertToNull username=root password=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
