springboot+Mybatis-plue自动生成代码

首先在pom.xml中引入相关依赖

		<!--mybatis-plus-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.3.0</version>
        </dependency>

        <!-- MP 核心库 -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus</artifactId>
            <version>3.3.0</version>
        </dependency>

        <!-- mybatisplus逆向工程需要模板引擎，用freemaker也行 -->
        <dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity-engine-core</artifactId>
            <version>2.0</version>
        </dependency>

        <!--mybatisplus代码生成器-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.2.0</version>
        </dependency>

编写代码生成类

package com.mckj.test;

import com.baomidou.mybatisplus.annotation.DbType;
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;
import org.junit.Test;

public class Test1 {
    @Test
    public void testGenerator(){
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        gc.setOutputDir("F:\\activiti7\\actiworkspace\\djactiviti\\src\\main\\java");//目录到scr\main\java
        gc.setFileOverride(true);
        gc.setActiveRecord(false);// 不需要ActiveRecord特性的请改为false
        gc.setEnableCache(false);// XML 二级缓存
        gc.setBaseResultMap(true);// XML ResultMap
        gc.setBaseColumnList(false);// XML columList
        gc.setAuthor("admin");// 作者

        // 自定义文件命名，注意 %s 会自动填充表实体属性！
        gc.setControllerName("%sController");
        gc.setServiceName("%sService");
        gc.setServiceImplName("%sServiceImpl");
        gc.setMapperName("%sMapper");
        gc.setXmlName("%sMapper");
        mpg.setGlobalConfig(gc);

        // 数据源配置(数据库为postgresql,如果为mysql请更改相关驱动)
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setDbType(DbType.POSTGRE_SQL);
        dsc.setDriverName("org.postgresql.Driver");
        dsc.setUsername("root");
        dsc.setPassword("root");
        dsc.setUrl("jdbc:postgresql://127.0.0.1:5432/djactiviti");
        mpg.setDataSource(dsc);

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setTablePrefix(new String[] { "tb_" });// 此处可以修改为您的表前缀
        strategy.setNaming(NamingStrategy.underline_to_camel);// 表名生成策略
        strategy.setInclude(new String[] { "tb_user","tb_holiday" }); // 需要生成的表

        strategy.setSuperServiceClass(null);
        strategy.setSuperServiceImplClass(null);
        strategy.setSuperMapperClass(null);

        mpg.setStrategy(strategy);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.example.holiday");
        pc.setController("controller");
        pc.setService("service");
        pc.setServiceImpl("service.impl");
        pc.setMapper("mapper");
        pc.setEntity("entity");
        pc.setXml("xml");
        mpg.setPackageInfo(pc);

        // 执行生成
        mpg.execute();

    }
}

application.yml中mybatis-plus相关设置

# 配置mybatis-plus
mybatis-plus:
  # 配置扫描xml
  mapper-locations:
    - classpath:mapper/*.xml
  # 实体扫描，多个package用逗号或者分号分隔
  type-aliases-package: com.example.holiday.entity
  global-config:
    # 逻辑删除配置
    logic-delete-value: 0
    logic-not-delete-value: 1

在启动类Aplication.class中添加@MapperScan注解

@SpringBootApplication
@MapperScan("com.example.holiday.mapper")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
