前言
之前有做個一個自定義報表的查詢，這里使用的是一個動態的sql拼接，是前端選擇了什么指標就查詢什么信息！（這里的指標是多個表的字段，前端隨便選擇了這些指標，然后后端根據這些指標拼接sql，返回這些指標的數據）。
參數接受DTO
public class DefinedReportFormDTO {
/**
* 指標id
*/
private List ids;
/**
* 開始時間
*/
@DateTimeFormat(pattern = "yyyy-MM")
private Date startTime;
/**
* 結束時間
*/
@DateTimeFormat(pattern = "yyyy-MM")
private Date endTime;
/**
* 頻率
*/
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;
}
}
數據返回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){
//測試數據
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));
}

這個repository要繼承 extends JpaRepository<T, ID> 才可以，寫漏了。
上面使用了union 進行表之間的關聯查詢，關聯的表有點多，所以代碼有些長，同時因為表多，指標（表的屬性）有500多個，無法確定查詢的返回實體，所以只能自己根據數據的返回給數據綁定屬性。
