mybatis-plus分页插件配置

package com.atguigu.eduservice.config;

import com.baomidou.mybatisplus.core.injector.ISqlInjector;
import com.baomidou.mybatisplus.extension.injector.LogicSqlInjector;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@MapperScan("com.atguigu.eduservice.mapper")
public class EduConfig {
    /**
     * 逻辑删除插件
     */
    @Bean
    public ISqlInjector sqlInjector() {
        return new LogicSqlInjector();
    }

    /**
     * 分页插件
     */
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }
}

2、分页Controller方法

//分页查询teacher
    @ApiOperation(value = "分页查询讲师")
    @GetMapping("pageTeacher/{page}/{limit}")
    public R pageListTeacher(@PathVariable long page, @PathVariable long limit) {
        //创建page对象
        Page<EduTeacher> teacherPage = new Page<>(page,limit);
        //调用方法实现分页
        //调用方法时，底层封装，把分页所有数据封装到teacherPage
        IPage<EduTeacher> pageTeacher = eduTeacherService.page(teacherPage, null);
        long total = pageTeacher.getTotal();
        List<EduTeacher> records = pageTeacher.getRecords();

        Map map = new HashMap();
        map.put("total",total);
        map.put("rows",records);

        return R.ok().data(map);
    }
