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);
}
}
