使用软件:IDEA,Hbuilder,navcat
一.创建springboot项目

</project>

三.由于我们需要分页功能,所以需要使用一个page工具类
PageUtil类


import lombok.Data;

/**
 * 封装分页类
 *
 * @author cjt
 *
 */
@Data
public class PageUtil {

    // 这两个属性叫这个名字,是为了对应layui的laytable分页参数
    private int page = 1;// 当前页数
    private int limit = 10;// 每页显示多少条
    private int offset;// 偏移量 从哪个下标开始,sql语句limit后的第一个数字

    /*
     * 其实不需要这样设置offset 1.前端layui自己管理分页 2.持久层mybatis plus自己处理偏移量 3.以上两者都只需要页码和条数就行了
     */
    public void setOffset(int page) {
        this.page = page;
        this.offset = (this.page - 1) * this.limit;
    }

}

四.添加配置

spring.datasource.url=jdbc:mysql://localhost:3306/vue?characterEncoding=utf-8&serverTimezone=UTC
spring.datasource.username=root
spring.datasource.password=root
#新版名称已更新,请注意
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
## Mybatis 配置
# 实体所在包,给实体类起别名,xml里面的返回值和入参用到时直接写类名就行了
mybatis.typeAliasesPackage=com.cjt.domain
# 映射文件所在路径
mybatis.mapperLocations=classpath:mapper/*.xml

五.mybatis反向生成
CodeGenerator类

import com.baomidou.mybatisplus.core.toolkit.StringPool;
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;

// 演示例子,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 {
    public static void main(String[] args) {
//        assert (false) : "代码生成属于危险操作,请确定配置后取消断言执行代码生成!";
        AutoGenerator mpg = new AutoGenerator();
        // 选择 freemarker 引擎,默认 Velocity
        mpg.setTemplateEngine(new FreemarkerTemplateEngine());

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        gc.setAuthor("cjt");
        gc.setOpen(false);//不要打开生成后的目录
        String projectPath = System.getProperty("user.dir");//获取项目根目录
        gc.setOutputDir(projectPath + "/src/main/java");
        gc.setFileOverride(false);// 是否覆盖同名文件,默认是false
        gc.setActiveRecord(true);// 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
        /* 自定义文件命名,注意 %s 会自动填充表实体属性! */
        gc.setServiceName("%sService");//默认生成的service接口会以I开头
        mpg.setGlobalConfig(gc);

        // 数据源配置
        DataSourceConfig dsc = new DataSourceConfig();
        //dsc.setDbType(DbType.MYSQL);
        dsc.setDriverName("com.mysql.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("root");
        dsc.setUrl("jdbc:mysql://localhost:3306/vue?serverTimezone=GMT%2B8");//此处填写数据库名称(我的是vue)
        mpg.setDataSource(dsc);

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        // strategy.setCapitalMode(true);// 全局大写命名 ORACLE 注意
        //strategy.setTablePrefix(new String[]{""});// 此处可以修改为您的表前缀
        strategy.setNaming(NamingStrategy.underline_to_camel);// 表名生成策略,下划线转驼峰
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);//列名下划线转驼峰
        strategy.setInclude(new String[]{"user"}); // 需要生成的表
        // strategy.setExclude(new String[]{"test"}); // 排除生成的表
        strategy.setEntityLombokModel(true);//实体类使用lombok
        // 自定义实体父类
        // strategy.setSuperEntityClass("com.baomidou.demo.TestEntity");
        // 自定义实体,公共字段
        // strategy.setSuperEntityColumns(new String[] { "test_id", "age" });
        // 自定义 mapper 父类
        // strategy.setSuperMapperClass("com.baomidou.demo.TestMapper");
        // 自定义 service 父类
        // strategy.setSuperServiceClass("com.baomidou.demo.TestService");
        // 自定义 service 实现类父类
        // strategy.setSuperServiceImplClass("com.baomidou.demo.TestServiceImpl");
        // 自定义 controller 父类
        // strategy.setSuperControllerClass("com.baomidou.demo.TestController");
        // 【实体】是否生成字段常量(默认 false)
        // public static final String ID = "test_id";
        // strategy.setEntityColumnConstant(true);
        // 【实体】是否为构建者模型(默认 false)
        // public User setName(String name) {this.name = name; return this;}
        // strategy.setEntityBuilderModel(true);
        mpg.setStrategy(strategy);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setParent("com.cjt");//包名
        // pc.setModuleName("test");
        mpg.setPackageInfo(pc);

        // 注入自定义配置,可以在 VM 中使用 cfg.abc 【可无】
        InjectionConfig cfg = new InjectionConfig() {
            @Override
            public void initMap() {
            }
        };
        // 如果模板引擎是 freemarker
        String templatePath = "/templates/mapper.xml.ftl";
        // // 自定义 xxList.jsp 生成
        List<FileOutConfig> focList = new ArrayList<>();
        // focList.add(new FileOutConfig("/template/list.jsp.vm") {
        // @Override
        // public String outputFile(TableInfo tableInfo) {
        // // 自定义输入文件名称
        // return "D://my_" + tableInfo.getEntityName() + ".jsp";
        // }
        // });
        // cfg.setFileOutConfigList(focList);
        // mpg.setCfg(cfg);
        //
        // 调整 xml 生成目录演示
        // 自定义输出配置
        // 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 , 如果你 Entity 设置了前后缀、此处注意 xml 的名称会跟着发生变化!!
                return projectPath + "/src/main/resources/mapper/" + tableInfo.getEntityName() + "Mapper" + StringPool.DOT_XML;
            }
        });
        cfg.setFileOutConfigList(focList);
        mpg.setCfg(cfg);
        // 关闭默认 xml 生成,调整生成 至 根目录
        TemplateConfig tc = new TemplateConfig();
        tc.setXml(null);
        mpg.setTemplate(tc);

        // 执行生成
        mpg.execute();

    }
}

六.Result结果返回类
这个功能已经在前面一篇文章讲过了,可以直接查看

@Controller @RequestMapping("/student") public class StudentController { @Autowired private StudentService studentService; @GetMapping("/getStu")// 客户端请求地址 public Object getAllStudent(Student student, Page<Student> page) {//返 回值和方法名,object表示可以返回任何对象,因为object是任何对象的父对象,要父给子没问匙 IPage<Student> allStu = studentService.getStudent(page, student); return Result.success(allStu); } }

        IPage<Student> getStudent(@Param("page") Page<Student> page, @Param("student") Student student);

十一.StudentMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.cjt.mapper.MembershipMapper">

    <!-- 通用查询映射结果 -->
    <resultMap id="BaseResultMap" type="com.cjt.domain.Membership">
        <id column="m_id" property="mId" />
        <result column="m_dep" property="mDep" />
        <result column="m_spe" property="mSpe" />

    public static void main(String[] args) {
        SpringApplication.run(ApplicationVue.class, args);
    }
}

启动:输入网址http://localhost:8080/student/getStu
此处的端口号是你设置的端口号,如有不同,请设置
