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
导入element分页插件
handleSizeChange:当改变每页显示的数据量时,触发该函数,页面刷新,并跳转到第一页。
handleCurrentChange:跳转到用户所选择的页面
