前言
之前有做个一个自定义报表的查询,这里使用的是一个动态的sql拼接,是前端选择了什么指标就查询什么信息!(这里的指标是多个表的字段,前端随便选择了这些指标,然后后端根据这些指标拼接sql,返回这些指标的数据)。
参数接受DTO
public class DefinedReportFormDTO { /** * 指标id */ private List ids; /** * 开始时间 */ @DateTimeFormat(pattern = "yyyy-MM") private Date startTime; /** * 结束时间 */ @DateTimeFormat(pattern = "yyyy-MM") private Date endTime; /** * 频率 */ private String timeStyle; private boolean avg =false; private String idsParam; private String companyIdsParam; public void setCompanyIdsParam(String companyIdsParam) { this.companyIdsParam = companyIdsParam; } public void setIdsParam(String idsParam) { this.idsParam = idsParam; } public String getCompanyIdsParam() { return companyIdsParam; } public String getIdsParam() { return idsParam; } public boolean isAvg() { return avg; } public void setAvg(boolean avg) { this.avg = avg; } public Date getStartTime() { return startTime; } public void setStartTime(Date startTime) { this.startTime = startTime; } public Date getEndTime() { return endTime; } public void setEndTime(Date endTime) { this.endTime = endTime; } public String getTimeStyle() { return timeStyle; } public void setTimeStyle(String timeStyle) { this.timeStyle = timeStyle; } public List getIds() { return ids; } public void setIds(List ids) { this.ids = ids; } }
数据返回VO
public class DefinedReportFormVO implements Serializable { private String time; private List<Map<String, Object>> arr = new ArrayList<>(); public String getTime() { return time; } public void setTime(String time) { this.time = time; } public List<Map<String, Object>> getArr() { return arr; } public void setArr(List<Map<String, Object>> arr) { this.arr = arr; } }
控制器Controller
@GetMapping("/report/defindReport") public JsonResponseExt defindReport(DefinedReportFormDTO definedReportFormDTO){ //测试数据 List list1 = new ArrayList<>(); list1.add("111"); definedReportFormDTO.setIds(list1); definedReportFormDTO.setTimeStyle("month"); definedReportFormDTO.setAvg(true); Calendar instance = Calendar.getInstance(); instance.set(2018,1,11); definedReportFormDTO.setStartTime(instance.getTime()); instance.setTime(new Date()); definedReportFormDTO.setEndTime(instance.getTime()); return JsonResponseExt.success(dataAcquisitionFileInfoService.defindQuery(definedReportFormDTO)); }
服务类Service
public interface DataAcquisitionFileInfoService { List<DefinedReportFormVO> defindQuery(DefinedReportFormDTO parameter); }

这个repository要继承 extends JpaRepository<T, ID> 才可以,写漏了。
上面使用了union 进行表之间的关联查询,关联的表有点多,所以代码有些长,同时因为表多,指标(表的属性)有500多个,无法确定查询的返回实体,所以只能自己根据数据的返回给数据绑定属性。
