Vue分页插件的前后端配置与使用

Posted in Javascript onOctober 09, 2019

本文实例为大家分享了Vue分页插件的前后端配置与使用，供大家参考，具体内容如下

分页插件的配置

<dependency>
 <groupId>com.github.pagehelper</groupId>
 <artifactId>pagehelper</artifactId>
 <version>5.1.10</version>
</dependency>
<dependency>
 <groupId>com.github.pagehelper</groupId>
 <artifactId>pagehelper-spring-boot-autoconfigure</artifactId>
 <version>1.2.10</version>
</dependency>

后端中的核心代码

1. 控制层代码

BusinessException异常是自定义的异常类型
CommonResponseUtils、ConversionUtils是自定义的工具类

以上代码在本博客均未列出

* @param commonRequest 前端请求
 * @return 返回给前端的数据
 */
@PostMapping(value = "/queryByCondition")
public CommonResponse<PageInfo<OrganizationDataListVO>> queryByCondition(@RequestBody CommonRequest<OrganizationQueryConditionVO> commonRequest){
 CommonRequestUtils.checkCommonRequest(commonRequest);
 try {
 OrganizationDTO dto = (OrganizationDTO) ConversionUtils.convertSimpleObject(commonRequest.getBody(),OrganizationDTO.class);
 PageInfo<OrganizationDTO> dtoPageInfo = organizationService.queryByCondition(dto);
 List<OrganizationDTO> dtoList = dtoPageInfo.getList();
 List<OrganizationDataListVO> vos = ConversionUtils.convertSimpleList(dtoList, OrganizationDataListVO.class);
 PageInfo<OrganizationDataListVO> voPageInfo = (PageInfo<OrganizationDataListVO>) ConversionUtils.convertSimpleObject(dtoPageInfo, PageInfo.class);
 voPageInfo.setList(vos);
 return CommonResponseUtils.makeSuccessCommonResponse(voPageInfo, "0", null, null, null);
 } catch (ServiceException exception) {
 throw new BusinessException(exception);
 } catch (IllegalAccessException | InstantiationException e) {
 throw new BusinessException(SystemExceptionEnum.SYSTEM_ERROR);
 }
}

实体类

OrganizationDataListVO

package com.bosssoft.bes.userpermission.pojo.vo;

import com.bosssoft.bes.userpermission.pojo.base.DataListVO;

import java.io.Serializable;

/**
 * @author 
 * @date 2019-08-25 18:43
 */
public class OrganizationDataListVO extends DataListVO implements Serializable {

 /**
 * 机构名称
 */
 protected String name;

 /**
 * 机构代码
 */
 protected String code;

 /**
 * 负责人
 */
 protected String master;

 /**
 * 电话
 */
 protected String tel;

 /**
 * 地址
 */
 protected String address;

 public OrganizationDataListVO() {
 }

}

OrganizationQueryConditionVO

package com.bosssoft.bes.userpermission.pojo.vo;

import com.bosssoft.bes.userpermission.pojo.base.QueryConditionVO;

import java.io.Serializable;

/**
 * @author 
 * @date 2019-08-15 14:05

 */
public class OrganizationQueryConditionVO extends QueryConditionVO implements Serializable {

 /**
 * 机构名称
 */
 protected String name;

 public OrganizationQueryConditionVO() {
 }

 
}

2. 业务层代码

/**
 *
 * @param organizationDTO
 * @return
 * @throws ServiceException
 */
public PageInfo<OrganizationDTO> queryByCondition(OrganizationDTO organizationDTO) {
 Condition condition = new Condition(Organization.class);
 Example.Criteria criteria = condition.createCriteria();
 if (!StringUtils.isEmpty(organizationDTO.getName())) {
 criteria.andLike("name", organizationDTO.getName() + "%");
 }
 condition.setOrderByClause("updated_time DESC");
 PageHelper.startPage(organizationDTO.getPageNum(), organizationDTO.getPageSize());
 List<Organization> results = organizationDao.selectByExample(condition);
 PageInfo<Organization> organizationPageInfo = new PageInfo<Organization>(results);
 List<OrganizationDTO> dtos = null;
 OrganizationDTO dto = null;
 dtos = new ArrayList<OrganizationDTO>(results.size());
 for (Organization result : results) {
 dto = new OrganizationDTO();
 BeanUtils.copyProperties(result, dto);
 dtos.add(dto);
 }
 PageInfo<OrganizationDTO> organizationDtoPageInfo = new PageInfo<OrganizationDTO>();
 BeanUtils.copyProperties(organizationPageInfo, organizationDtoPageInfo);
 organizationDtoPageInfo.setList(dtos);
 return organizationDtoPageInfo;
}

实体类

OrganizationDTO

package com.bosssoft.bes.userpermission.pojo.dto;

import com.bosssoft.bes.userpermission.pojo.base.BaseDTO;

import java.util.List;

/**
 * @author 
 * @date 2019-08-15 14:09

 */
public class OrganizationDTO extends BaseDTO {

 /**
 * 所含公司列表
 */
 protected List<CompanyDTO> companyDtoList;

 /**
 * 机构名称
 */
 protected String name;

 /**
 * 机构代码
 */
 protected String code;

 /**
 * 负责人
 */
 protected String master;

 /**
 * 电话
 */
 protected String tel;

 /**
 * 地址
 */
 protected String address;

 public OrganizationDTO() {
 }
 
}

Organization

package com.bosssoft.bes.userpermission.pojo.entity;

import com.bosssoft.bes.userpermission.pojo.base.BaseEntity;
import org.springframework.stereotype.Repository;

import javax.persistence.Table;
import java.io.Serializable;

/**
 * @author 
 * @date 2019-08-15 10:49

 */
@Repository
@Table(name = "t_organization")
public class Organization extends BaseEntity implements Serializable {
 //private static final long serialVersionUID = 1L;

 /**
 * 机构名称
 */
 protected String name;

 /**
 * 机构代码
 */
 protected String code;

 /**
 * 负责人
 */
 protected String master;

 /**
 * 电话
 */
 protected String tel;

 /**
 * 地址
 */
 protected String address;

 public Organization() {
 }



}

3. DAO层

引用了通用mapper

前端中的代码
