2. 配置application.yml文件

#配置tomcat
server:
  port: 8080

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/zmall?useUnicode=true&characterEncoding=UTF-8&useSSL=false
    username: root

    content-type: text/html
    #模板前缀
    template-loader-path: classpath:/templates/
    #启用模板
    enabled: true

#配置mybatis
mybatis-plus:
  #配置SQL映射文件路径
  mapper-locations: classpath:mapper/*.xml
  #配置别名
  type-aliases-package: com.jmh.mp.model
  #开启驼峰命名
  configuration:
    map-underscore-to-camel-case: true
#配置日志输出
logging:
  level:

3. mybatis-plus插件配置核心类

package com.jmh.mp.config;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.autoconfigure.ConfigurationCustomizer;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MybatisPlusConfig {

    /**
     * 新的分页插件,一缓和二缓遵循mybatis的规则,需要设置 MybatisConfiguration#useDeprecatedExecutor = false 避免缓存出现问题(该属性会在旧插件移除后一同移除)
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.H2));
        return interceptor;
    }
}

4. 启动类配置

package com.jmh.mp;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.jmh.mp.mapper")
public class Mp01Application {

    public static void main(String[] args) {
        SpringApplication.run(Mp01Application.class, args);
    }

}

5. 测试数据Sql脚本

• 代码生成后项目结构

7. 测试分页查询

• 采用junit测试 

package com.jmh.mp;

import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.jmh.mp.mapper.UserMapper;
import com.jmh.mp.model.User;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class Mp01ApplicationTests {

    @Autowired
    private UserMapper userMapper;


    @Test
    void contextLoads() {

        Page userPage = userMapper.selectPage(new Page()
                        .setCurrent(1)//当前页
                        .setSize(10)//当前页大小
                , new QueryWrapper());
        System.out.println("总数据量:" + userPage.getTotal());
        System.out.println("当前页码:" + userPage.getCurrent());
        System.out.println("当前页大小:" + userPage.getSize());
        userPage.getRecords().forEach(System.out::println);


    }

}

•  结果
