mybatis-plus分页插件 实现查询分页 （springBoot）

 pom.xml添加依赖

 <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.0-alpha</version>
 </dependency>

模块目录结构 （DiseaseMapper 、 DiseaseMapper.xml在其他包中）

MybatisPlusConfig

package com.xxx.xxx.disease.controllers;

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;

/**
 * @author ya
 * @date 2018/7/19 20:27
 */
@Configuration
@MapperScan("com.xxx.xxx")
public class MybatisPlusConfig {

    /**
     * mybatis-plus分页插件<br>
     * 文档：http://mp.baomidou.com<br>
     */
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        return paginationInterceptor;
    }


}

 DiseasseController

/**
     * 查询疾病信息，若无对属性值进行筛选则显示所有疾病信息
     * @param currentPage 当前页面
     * @param disease 疾病实体类，根据有传值的属性进行筛选
     * @return
     */
    @RequestMapping("selectByPage")
    public ApiResult showByPage(@RequestParam("currentPage") Integer currentPage,
                                @RequestParam("pageSize") Integer pageSize,
                                Disease disease){
        Page<Disease> page = new Page<Disease>(currentPage,pageSize);
        QueryWrapper<Disease> diseaseQueryWrapperw = new QueryWrapper<Disease>(disease);
        IPage<Disease> page1 = diseaseMapper.selectPage(page, diseaseQueryWrapperw);
        
        return ApiResult.valueOf(page1); //ApiResult是对json格式的统一
    }
