Spingboot+MybatisPlus構建代碼生成器

　　之前項目一直使用ssm較多,對springboot僅局限於知道,但是並未使用過.正好公司因為新項目需要用到springboot,mybatis_plus,所以學習了一下,使用了mp的代碼生成;

　　LZ使用的開發環境及版本如下: JDK1.8 　　Eclipse4.7 　　 springboot 2.1.4  

　　整個目錄結構如下圖

 創建config文件夾,新建數據源配置文件和mp配置文件,代碼如下

package com.hxb.config;

import javax.sql.DataSource;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.alibaba.druid.pool.DruidDataSource;

/**
 * @description:數據源配置文件
 * @author: yshexiaobai
 * @Date: 2019年9月5日 上午11:20:40
 */
@Configuration
public class DataSourceConfig {
    
    @Bean(name="dataSource")
    public DataSource dataSource() {
        return new DruidDataSource();
    }
}

package com.hxb.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;

/**
 * 
 * @description: mybatisplus配置文件
 * @author: yshexiaobai
 * @Date: 2019年9月5日 上午11:27:12
 */
@Configuration
public class MybatisPlusConfig {
    
    /**
     * 配置分頁插件
     * @return
     */
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor page = new PaginationInterceptor();
        page.setDialectType("mysql");
        return page;
    }
    

}

創建generator文件夾,並在文件夾新建類MPGenerator

package com.hxb.generator;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
import com.baomidou.mybatisplus.generator.config.GlobalConfig;
import com.baomidou.mybatisplus.generator.config.PackageConfig;
import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

/**
 * 
 * @description:MP代碼生成器
 * @author: yshexiaobai
 * @Date: 2019年9月5日 上午11:40:07
 */
public class MPGenerator {
    
    public static void main(String[] args) {
        //創建代碼生成器
        AutoGenerator mpg = new AutoGenerator();
        //指定模板引擎  默認velocity 
        //mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        
        //全局配置
        GlobalConfig gc = new GlobalConfig();
        gc.setOpen(false);
        gc.setOutputDir("D:\\personalspace\\mptest\\src\\main\\java");
        gc.setFileOverride(true); //是否覆蓋已有文件
        gc.setBaseResultMap(true); //XML是否需要BaseResultMap
        gc.setBaseColumnList(true); //XML是否顯示字段
        gc.setControllerName("%sController");
        gc.setServiceName("%sService");
        gc.setServiceImplName("%sServiceImpl");
        gc.setMapperName("%sMapper");
        gc.setXmlName("%sMapper");
        gc.setAuthor("yshexiaobai");
        gc.setIdType(IdType.AUTO);
        mpg.setGlobalConfig(gc);    
        //數據源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setDbType(DbType.MYSQL);
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUrl("jdbc:mysql://127.0.0.1:3306/dinnerbook?characterEncoding=utf8&useSSL=false");
        dsc.setUsername("root");
        dsc.setPassword("123456");
        mpg.setDataSource(dsc);
        //策略配置
        StrategyConfig sc = new StrategyConfig();
        sc.setTablePrefix("tab_"); //表名前綴
        sc.setNaming(NamingStrategy.underline_to_camel); //表名生成策略 
        sc.setEntityBuilderModel(true);
        sc.setEntityLombokModel(true);
        mpg.setStrategy(sc);
        //包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.hxb");
        pc.setEntity("entity");
        pc.setController("controller");
        pc.setService("service");
        pc.setServiceImpl("serviceImpl");
        pc.setMapper("mapper");
        pc.setXml("mapper");
        mpg.setPackageInfo(pc);
    
        mpg.execute();
    }

}

運行MPGenerator,則開始自動生成文件.
