MySpringboot+mybatis+bootstrap-paginator实现分页

MySpringboot+mybatis+bootstrap-paginator实现分页

第一步：pom.xml中导入相关依赖

     <dependency>
        <groupId>com.github.pagehelper</groupId>
        <artifactId>pagehelper-spring-boot-starter</artifactId>
        <version>1.2.3</version>
    </dependency>
    
	<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>    

	 <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.0.0</version>
    </dependency>

第二步：实体类页面代码

package com.example.shop.entity;

import …;

private Integer goodsId;

private String goodsName;

private BigDecimal goodsPrice;

private Integer marchNum;

private Integer cautionNum;

private Integer planNum;

private String barCode;

private BigDecimal salesProPrice;

private Date salesProDateS;

private Date salesProDateE;

private Integer allowAbate;

private Integer allowSale;

private Integer factoryId;

private Integer provideId;

public Integer getGoodsId() {
    return goodsId;
}

public void setGoodsId(Integer goodsId) {
    this.goodsId = goodsId;
}

public String getGoodsName() {
    return goodsName;
}

public void setGoodsName(String goodsName) {
    this.goodsName = goodsName;
}

public BigDecimal getGoodsPrice() {
    return goodsPrice;
}

public void setGoodsPrice(BigDecimal goodsPrice) {
    this.goodsPrice = goodsPrice;
}

public Integer getMarchNum() {
    return marchNum;
}

public void setMarchNum(Integer marchNum) {
    this.marchNum = marchNum;
}

public Integer getCautionNum() {
    return cautionNum;
}

public void setCautionNum(Integer cautionNum) {
    this.cautionNum = cautionNum;
}

public Integer getPlanNum() {
    return planNum;
}

public void setPlanNum(Integer planNum) {
    this.planNum = planNum;
}

public String getBarCode() {
    return barCode;
}

public void setBarCode(String barCode) {
    this.barCode = barCode;
}

public BigDecimal getSalesProPrice() {
    return salesProPrice;
}

public void setSalesProPrice(BigDecimal salesProPrice) {
    this.salesProPrice = salesProPrice;
}

public Date getSalesProDateS() {
    return salesProDateS;
}

public void setSalesProDateS(Date salesProDateS) {
    this.salesProDateS = salesProDateS;
}

public Date getSalesProDateE() {
    return salesProDateE;
}

public void setSalesProDateE(Date salesProDateE) {
    this.salesProDateE = salesProDateE;
}

public Integer getAllowAbate() {
    return allowAbate;
}

public void setAllowAbate(Integer allowAbate) {
    this.allowAbate = allowAbate;
}

public Integer getAllowSale() {
    return allowSale;
}

public void setAllowSale(Integer allowSale) {
    this.allowSale = allowSale;
}

public Integer getFactoryId() {
    return factoryId;
}

public void setFactoryId(Integer factoryId) {
    this.factoryId = factoryId;
}

public Integer getProvideId() {
    return provideId;
}

public void setProvideId(Integer provideId) {
    this.provideId = provideId;
}

}

第三步：Mapper 接口页面代码
package com.example.shop.mapper;

import …;

public interface GoodsInfoMapper {

public List<GoodsInfo> selectAll();

}

第五步：service页面代码
package com.example.shop.service;

import …;

import javax.annotation.Resource;
import java.util.List;

@Service
public class GoodsInfoService {

@Resource
private GoodsInfoMapper goodsInfoMapper;

public List<GoodsInfo> findAll(){
    return goodsInfoMapper.selectAll();
}

}

第六步：PaginationConstant 接口，用于保存初始页页码，和每页显示数据大小
package com.example.shop.util;

public interface PaginationConstant {
    /**
     * 当前面，默认为1
     */
    public static final int CURRENT_NUM=1;

    /**
     * 每页显示条数，默认5条
     */
    public static final int PAGE_SIZE=2;
    
}

第七步：controller页面代码
package com.example.shop.controller;
import …;

@Controller
@RequestMapping(value={"/goods"})
public class GoodsInfoController {

@Resource
private GoodsInfoService goodsInfoService;

@RequestMapping(value={"/findAll"})
public String findAll(Model model,Integer pageNum) {
    if(ObjectUtils.isEmpty(pageNum)){
        pageNum=PaginationConstant.CURRENT_NUM;
    }
    //设置分页(当前页，和每页显示数据条数)
    PageHelper.startPage(pageNum, PaginationConstant.PAGE_SIZE);
    //查找数据
    List<GoodsInfo> goodsInfoList = goodsInfoService.findAll();
        //将查找出的结果封装到PageInfo对象中，这个对象包含了 goodsInfoList集合和关于分页的方法，如下
        //pageInfo.getPageNum(); 
        //pageInfo.getPages(); 得到总页数
        //pageInfo.getNextPage(); 得到下一页
        //pageInfo.getPrePage(); 得到前一页
        PageInfo<GoodsInfo> pageInfo=new PageInfo<>(goodsInfoList);
       // model.addAttribute("goodsInfoList",goodsInfoList);
       //用Model传递对象到GoodsInfo页面
        model.addAttribute("pageInfo",pageInfo);
    	return "GoodsInfo";
    }

}

第八步：HTML页面代码
