目录结构
1.导入lib中的jar包
2.修改配置文件
<?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> <!-- context元素用于指定生成一组对象的环境。targetRuntime:此属性用于指定生成的代码的运行时环境。MyBatis3:*这是默认值*--> <context id="testTables" targetRuntime="MyBatis3"> <commentGenerator> <!-- 是否去除自动生成的注释 true:是 : false:否 --> <property name="suppressAllComments" value="true" /> </commentGenerator> <!--数据库连接的信息:驱动类、连接地址、用户名、密码 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/mybatis?allowMultiQueries=true" userId="root" password="root"> </jdbcConnection> <!-- 如使用oracle请参考如下 --> <!-- <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:orcl" userId="scott" password="wcy675600920"> </jdbcConnection> --> <!-- 默认false,把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer,为 true时把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal --> <javaTypeResolver> <property name="forceBigDecimals" value="false" /> </javaTypeResolver> <!-- targetProject:生成PO类的位置 --> <javaModelGenerator targetPackage="com.hxlz.po" targetProject=".\src"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> <!-- 从数据库返回的值被清理前后的空格 --> <property name="trimStrings" value="true" /> </javaModelGenerator> <!-- targetProject:mapper映射文件生成的位置 --> <sqlMapGenerator targetPackage="com.hxlz.mapper" targetProject=".\src"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> </sqlMapGenerator> <!-- targetPackage:mapper接口生成的位置 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.hxlz.mapper" targetProject=".\src"> <!-- enableSubPackages:是否让schema作为包的后缀 --> <property name="enableSubPackages" value="false" /> </javaClientGenerator> <!-- 指定数据库表 --> <table tableName="items" schema="" enableCountByExample="false" enableDeleteByExample="false" enableUpdateByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> <table tableName="orders" schema="" enableCountByExample="false" enableDeleteByExample="false" enableUpdateByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> <table tableName="user" schema="" enableCountByExample="false" enableDeleteByExample="false" enableUpdateByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> <!-- 有些表的字段需要指定java类型 <table schema="" tableName=""> <columnOverride column="" javaType="" /> </table> --> </context> </generatorConfiguration>
3.运行主类
import java.io.File; import java.util.ArrayList; import java.util.List; import org.mybatis.generator.api.MyBatisGenerator; import org.mybatis.generator.config.Configuration; import org.mybatis.generator.config.xml.ConfigurationParser; import org.mybatis.generator.internal.DefaultShellCallback; public class GeneratorSqlmap { public void generator() throws Exception{ List<String> warnings = new ArrayList<String>(); boolean overwrite = true; File configFile = new File("config/generatorConfig.xml"); ConfigurationParser cp = new ConfigurationParser(warnings); Configuration config = cp.parseConfiguration(configFile); DefaultShellCallback callback = new DefaultShellCallback(overwrite); MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings); myBatisGenerator.generate(null); } public static void main(String[] args) throws Exception { try { GeneratorSqlmap generatorSqlmap = new GeneratorSqlmap(); generatorSqlmap.generator(); } catch (Exception e) { e.printStackTrace(); } } }
