2.application.properties配置文件

#访问相关配置
server.port=8099
server.tomcat.uri-encoding=utf-8
#项目访问名称，如果不配置直接访问bean就可用
server.servlet.context-path=/demo
#数据库连接
spring.datasource.url = jdbc:mysql://localhost:3306/demo
spring.datasource.username = root
spring.datasource.password = 123
spring.datasource.driverClassName = com.mysql.jdbc.Driver
#spring boot视图配置
spring.mvc.view.prefix=/WEB-INF/
spring.mvc.view.suffix=.jsp
logging.level.cn.piesat.mapper=debug
#设定ftl文件路径
spring.freemarker.template-loader-path=classpath:/templates
#设定静态文件路径，js,css等
spring.mvc.static-path-pattern=/static/**

#设置mapper文件的位置
mybatis-plus.mapper-locations: classpath*:com/example/demo/mapper/*.xml
mybatis-plus.type-aliases-package=cmo.example.demo.bean;cmo.example.demo.entity;
#mybatis.mapper-locations=classpath*:com/example/demo/mapper/*.xml
#mybatis.mapperLocations=classpath*:com/example/demo/mapper/*.xml
#mybatis.type-aliases-package=com.example.demo.bean

3.创建创建mybatis生成器类

包路径com.example.demo.generator

创建类----》参考官方文档mybatis-plus:https://mp.baomidou.com/guide

package com.example.demo.generator;

import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;
import com.baomidou.mybatisplus.core.toolkit.StringPool;
import com.baomidou.mybatisplus.core.toolkit.StringUtils;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.InjectionConfig;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

/**
 * 执行 main 方法控制台输入模块表名回车自动生成对应项目目录中
 */
public class CodeGenerator {

    /**
     * 

     * 读取控制台内容
     * 
     */
    public static String scanner(String tip) {
        Scanner scanner = new Scanner(System.in);
        StringBuilder help = new StringBuilder();
        help.append("请输入" + tip + "：");
        System.out.println(help.toString());
        if (scanner.hasNext()) {
            String ipt = scanner.next();
            if (StringUtils.isNotEmpty(ipt)) {
                return ipt;
            }
        }
        throw new MybatisPlusException("请输入正确的" + tip + "！");
    }
    public static void main(String[] args) {
        // 代码生成器
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        String projectPath = System.getProperty("user.dir");
        gc.setOutputDir(projectPath + "/src/main/java");
        gc.setAuthor("jobob");
        gc.setOpen(false);
        mpg.setGlobalConfig(gc);

        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://localhost:3306/myblog?useUnicode=true&useSSL=false&characterEncoding=utf8");
        // dsc.setSchemaName("public");
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUsername("myblog");
        dsc.setPassword("myblog");
        mpg.setDataSource(dsc);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setModuleName(scanner("模块名"));
        pc.setParent("com.example"); //com.baomidou.ant
        mpg.setPackageInfo(pc);

        // 自定义配置
        InjectionConfig cfg = new InjectionConfig() {
            @Override
            public void initMap() {
                // to do nothing
            }
        };

        // 如果模板引擎是 freemarker
        String templatePath = "/templates/mapper.xml.ftl";
        // 如果模板引擎是 velocity
        // String templatePath = "/templates/mapper.xml.vm";

        // 自定义输出配置
        List focList = new ArrayList<>();
        // 自定义配置会被优先输出
        focList.add(new FileOutConfig(templatePath) {
            @Override
            public String outputFile(TableInfo tableInfo) {
                // 自定义输出文件名
                return projectPath + "/src/main/resources/mapper/" + pc.getModuleName()
                        + "/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
            }
        });

        cfg.setFileOutConfigList(focList);
        mpg.setCfg(cfg);

        // 配置模板
        TemplateConfig templateConfig = new TemplateConfig();

        // 配置自定义输出模板
        // templateConfig.setEntity();
        // templateConfig.setService();
        // templateConfig.setController();

        templateConfig.setXml(null);
        mpg.setTemplate(templateConfig);

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        strategy.setSuperEntityClass("com.baomidou.ant.common.BaseEntity");
        strategy.setEntityLombokModel(true);
        strategy.setRestControllerStyle(true);
        strategy.setSuperControllerClass("com.baomidou.ant.common.BaseController");
        strategy.setInclude(scanner("表名"));
        strategy.setSuperEntityColumns("id");
        strategy.setControllerMappingHyphenStyle(true);
        strategy.setTablePrefix(pc.getModuleName() + "_");
        mpg.setStrategy(strategy);
        mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        mpg.execute();
    }

}

main函数启动，输入项目名+输入表名---》自动创建entity / mapper / srvice / controller 

4.编写controller 测试方法，运行springboot

package com.example.demo.controller;


import com.example.demo.entity.Tuser;
import com.example.demo.service.ITuserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
//import com.baomidou.ant.common.BaseController;

import java.util.List;

/**
 * 

 * 用户 前端控制器
 * 
 *
 * @author jobob
 * @since 2019-01-08
 */
@RestController
@RequestMapping("/demo/tuser")
public class TuserController /*extends BaseController*/ {
    @Autowired
    ITuserService service;

    @RequestMapping("")
    @ResponseBody
    public String test(){
        List list = service.list(null);
        System.out.println(list.size());
        return "123";
    }

}

访问最终效果：http://localhost:8099/demo/demo/tuser
