MybaitsPlus分页查询

    com.baomidou
    mybatis-plus-boot-starter
    3.4.1

对dao层的单表查询，mybaitsPlus已经做了封装，直接调用就行。例：

@Autowired
private UserDao userDao;
@Test
void test() {
    List users = userDao.selectList(null);
    System.out.println(users);
}

提示：以下是本篇文章正文内容，下面案例可供参考

（国内开发）加强版的mybaits,使用spring boot整合mybaitsPlus之后，操作会更加快捷，方便

package com.example.config;

import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MpConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor(){
        //定义Mp拦截器
        MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();

        mybatisPlusInterceptor.addInnerInterceptor(new PaginationInnerInterceptor());
        return mybatisPlusInterceptor;
    }
}

代码如下（示例）：

@Test
void test2(){
    IPage userPage = new Page<>(1,3);
    userDao.selectPage(userPage,null);
    System.out.println("当前页码值"+userPage.getCurrent());
    System.out.println("一共多少页"+userPage.getPages());
    System.out.println("每页多少条数据"+userPage.getSize());
    System.out.println("一共多少条数据"+userPage.getTotal());
    System.out.println("数据"+userPage.getRecords());

}
