SpringBoot13 利用mybatis-plus自动生成entity、dao、service、controller

1 环境配置

2 新建一个新的springboot项目

　　2.1 选择一些必要的依赖

　　2.3 配置数据源

server:
  servlet:
    context-path: /dev
  port: 9999

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/testdemo?useUnicode=true&characterEncoding=UTF-8&&useSSL=false
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: root
#  jpa:
#    database: mysql
#    properties:
#      hibernate:
#        show-sql: true
#        format-sql: true
  jpa:
    database: mysql
    show-sql: true

　　2.4 编写一个测试控制层

package cn.test.demo.mybatis_demo.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author 王杨帅
 * @create 2018-04-06 21:11
 * @desc 测试控制类
 **/
@RestController
@RequestMapping(value = "/test")
public class TestContorller {

    @GetMapping(value = "test01")
    public String test01() {
        String result = "===test01===";
        System.out.println(result);
        return result;
    }
}

　　2.5 编写代生成器

　　　　需要根据自己需要更改生成文件存放位置，以及一些其他信息

package cn.test.demo.mybatis_demo.util;

import com.baomidou.mybatisplus.generator.config.StrategyConfig;
import com.baomidou.mybatisplus.generator.config.rules.DbType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;

/**
 * @author 王杨帅
 * @create 2018-04-06 21:43
 * @desc 自动生成代码工具类
 **/
public class AutoGenerateCode {
    public static void main(String[] args) throws InterruptedException {
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置定义
        GlobalConfig gc = new GlobalConfig();

        gc.setBaseResultMap(true);// XML ResultMap
        gc.setBaseColumnList(true);// XML columList
        gc.setAuthor("王杨帅"); // 作者信息

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

        // 数据源配置定义
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setDbType(DbType.MYSQL);
        /*dsc.setTypeConvert(new MySqlTypeConvert(){
            // 自定义数据库表字段类型转换【可选】
            @Override
            public DbColumnType processTypeConvert(String fieldType) {
                System.out.println("转换类型：" + fieldType);
                return super.processTypeConvert(fieldType);
            }
        });*/
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUrl("jdbc:mysql://localhost:3306/testdemo?useUnicode=true&amp;characterEncoding=UTF-8&amp;generateSimpleParameterMetadata=true");
        dsc.setUsername("root");
        dsc.setPassword("182838");
        mpg.setDataSource(dsc); // 设置数据源

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        // strategy.setCapitalMode(true);// 全局大写命名 ORACLE 注意
        // strategy.setTablePrefix(new String[] { "tlog_", "tsys_" });// 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[] { "user" }); // 需要生成的表
        // strategy.setExclude(new String[]{"test"}); // 排除生成的表
        mpg.setStrategy(strategy);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("org");
        pc.setModuleName("ibase4j");
        mpg.setPackageInfo(pc);

        // 执行生成
        mpg.execute();
    }
