如何自动生成映射文件

一、pom.xml

pom.xml添加以下依赖：

                          org.mybatis.spring.boot            mybatis-spring-boot-starter            2.0.1                                    com.baomidou            mybatis-plus-boot-starter            3.0.3                            com.baomidou            mybatis-plus            3.0.3                            org.mybatis            mybatis-spring            1.3.2                            org.freemarker            freemarker            2.3.23                                    com.baomidou            mybatis-plus-generator

二、MybatisPlusUtil工具类

package com.yss.datamiddle.common;import com.baomidou.mybatisplus.annotation.DbType;import com.baomidou.mybatisplus.annotation.IdType;import com.baomidou.mybatisplus.generator.AutoGenerator;import com.baomidou.mybatisplus.generator.config.*;import com.baomidou.mybatisplus.generator.config.querys.DB2Query;import com.baomidou.mybatisplus.generator.config.rules.DateType;import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;import java.sql.*;import java.util.ArrayList;import java.util.List;/** * @description: 数据库生成JAVA类 * @create: 2020-07-20 14:00:00 * @update: 2020-07-20 14:00:00 */public class MybatisPlusUtils {    /**     * mysql自动代码生成类     *     * @param includeTables     * @param excludeTables     */    public static void generateMysql(String[] includeTables, String[] excludeTables, Boolean db1) {        AutoGenerator autoGenerator = new AutoGenerator();        /**         * 数据库配置         */        buildMysqlDb(autoGenerator);        StrategyConfig strategyConfig = new StrategyConfig();        // 驼峰命名        strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);        strategyConfig.setNaming(NamingStrategy.underline_to_camel);        strategyConfig.setInclude(includeTables);        strategyConfig.setExclude(excludeTables);        strategyConfig.setTablePrefix("");        autoGenerator.setStrategy(strategyConfig);        /**         * 全局配置         */        GlobalConfig globalConfig = new GlobalConfig();        globalConfig.setAuthor("Han LiDong");        globalConfig.setDateType(DateType.ONLY_DATE);        globalConfig.setActiveRecord(true);        globalConfig.setIdType(IdType.INPUT);        globalConfig.setOutputDir("C:/D/ORM");  //文件生成路径        globalConfig.setMapperName("%sMapper");        globalConfig.setServiceName("%sService");        globalConfig.setServiceImplName("%sServiceImpl");        globalConfig.setXmlName("%sMapper");        globalConfig.setSwagger2(true);        globalConfig.setFileOverride(true);        globalConfig.setBaseColumnList(false);        globalConfig.setBaseResultMap(false);        globalConfig.setEnableCache(false);        autoGenerator.setGlobalConfig(globalConfig);        /**         * 包名配置         */        PackageConfig packageConfig = new PackageConfig();        packageConfig.setParent("");        packageConfig.setEntity("com.yss.datamiddle.entity");        packageConfig.setMapper("com.yss.datamiddle.dao");        packageConfig.setXml("mapper");        packageConfig.setService("com.yss.datamiddle.service");        packageConfig.setServiceImpl("com.yss.datamiddle.impl");        packageConfig.setController("com.yss.datamiddle.controller");        autoGenerator.setPackageInfo(packageConfig);        // 采用默认模板,自定义模板参考@see com.baomidou.mybatisplus.generator.config.TemplateConfig//        TemplateConfig templateConfig = new TemplateConfig();        autoGenerator.setTemplateEngine(new FreemarkerTemplateEngine());        autoGenerator.execute();    }    /**     * oracle自动代码生成类     * @param includeTables     * @param excludeTables     */    public static void generateOracle(String[] includeTables, String[] excludeTables, Boolean db1) {        AutoGenerator autoGenerator = new AutoGenerator();        buildOracleDb(autoGenerator);        StrategyConfig strategyConfig = new StrategyConfig();        // 驼峰命名        strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);        strategyConfig.setNaming(NamingStrategy.underline_to_camel);        strategyConfig.setInclude(includeTables);        strategyConfig.setExclude(excludeTables);        strategyConfig.setTablePrefix("");        autoGenerator.setStrategy(strategyConfig);        /**         * 全局配置         */        GlobalConfig globalConfig = new GlobalConfig();        globalConfig.setAuthor("Han LiDong");        globalConfig.setDateType(DateType.ONLY_DATE);        globalConfig.setActiveRecord(true);        globalConfig.setIdType(IdType.AUTO);    //这里用oracle的序列和触发器实现主键自增        globalConfig.setOutputDir("C:/ORM");  //文件生成路径        globalConfig.setMapperName("%sMapper");        globalConfig.setServiceName("%sService");        globalConfig.setServiceImplName("%sServiceImpl");        globalConfig.setXmlName("%sMapper");        globalConfig.setSwagger2(true);        globalConfig.setFileOverride(true);        globalConfig.setBaseColumnList(false);        globalConfig.setBaseResultMap(false);        globalConfig.setEnableCache(false);        autoGenerator.setGlobalConfig(globalConfig);        /**         * 包名配置         */        PackageConfig packageConfig = new PackageConfig();        packageConfig.setParent("");        packageConfig.setEntity("com.yss.datamiddle.entity");        packageConfig.setMapper("com.yss.datamiddle.dao");        packageConfig.setXml("mapper");        packageConfig.setService("com.yss.datamiddle.service");        packageConfig.setServiceImpl("com.yss.datamiddle.impl");        packageConfig.setController("com.yss.datamiddle.controller");        autoGenerator.setPackageInfo(packageConfig);        // 采用默认模板,自定义模板参考@see com.baomidou.mybatisplus.generator.config.TemplateConfig//        TemplateConfig templateConfig = new TemplateConfig();        autoGenerator.setTemplateEngine(new FreemarkerTemplateEngine());        autoGenerator.execute();    }    private static void buildOracleDb(AutoGenerator autoGenerator) {        DataSourceConfig dataSourceConfig = new DataSourceConfig();        dataSourceConfig.setDbQuery(new MyDbQuery());   //自定义dbquery不然querydb.dbtype找不到        dataSourceConfig.setDbType(DbType.ORACLE);        dataSourceConfig.setDriverName("oracle.jdbc.driver.OracleDriver");        dataSourceConfig.setUsername("xxxxx");        dataSourceConfig.setPassword("xxxxx");        dataSourceConfig.setUrl("jdbc:oracle:thin:@192.168.xxx.xxx/orcl");        //dataSourceConfig.setUrl("jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false");        autoGenerator.setDataSource(dataSourceConfig);    }    private static void buildMysqlDb(AutoGenerator autoGenerator) {        DataSourceConfig dataSourceConfig = new DataSourceConfig();        dataSourceConfig.setDbType(DbType.MYSQL);        dataSourceConfig.setDriverName("com.mysql.jdbc.Driver");        dataSourceConfig.setUsername("root");        dataSourceConfig.setPassword("123456");        dataSourceConfig.setUrl("jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false");        autoGenerator.setDataSource(dataSourceConfig);    }    public static void main(String[] args) {        //String[] includeTables = {"hr_kpi_dept_person","sys_user"};        String[] includeTables = {"ETL_MIDDLE_STATE"};        //generateMysql(includeTables,null,false);  //mysql映射文件生成        generateOracle(includeTables,null,false);      //oracle映射文件生成    }}

右键 Run 运行之后就会生成一堆映射文件，将之copy到自己的项目中就可以了

注意: 生成的dao层文件需要自己添加@Mapper注解
