mybatis 自動生成工具java
最近在工做中使用到了mybatis,對於數據庫的javabean,orm映射配置文件,手動編寫有點繁瑣,同時又容易出錯,這裏就介紹一下mybatis-generator反向生成工具。mysql
1)所需文件:sql
generatorConfig.xml數據庫
mybatis-generator-core-1.3.4.jarapi
mysql-connector-java-5.1.28.jarmybatis
2)修改配置文件app
<?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> <!--數據庫驅動--> <classPathEntry location="mysql-connector-java-5.1.28.jar"/> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <property name="suppressAllComments" value="true"/> </commentGenerator> <!--數據庫連接地址帳號密碼--> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://10.107.134.26:8306/niux" userId="nuomi" password="nuomisc"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!--生成Model類存放位置--> <javaModelGenerator targetPackage="com.baidu.api.gateway.model" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!--生成映射文件存放位置--> <sqlMapGenerator targetPackage="com.baidu.api.gateway.mapper" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!--生成Dao類存放位置--> <javaClientGenerator type="XMLMAPPER" targetPackage="com.baidu.api.gateway.mapper" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!--生成對應表及類名--> <table tableName="gw_service_param_mapping" domainObjectName="GWServiceParamMapping" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> </context> </generatorConfiguration>
3)在該目錄下,執行以下命令:dom
java -jar mybatis-generator-core-1.3.4.jar -configfile generatorConfig.xml -overwrite
注意:若是使用該工具修改配置文件,xml不會覆蓋,只會追加,而java代碼會徹底覆蓋。 工具
