我在春天框架是新的。我通過查看頁面的$.post()方法發送請求，我的控制器從我的DAO類接收數據。但我沒有得到完整的數據。我張貼我的源代碼從春天控制器和jQuery的.post（）方法得到適當的json

$.post("/diusoftware/showAppraisalFormatWithDetails"+"/41",{id:41},function(data){ 
      alert(JSON.stringify(data)); 
     }, "json");

控制器

@Controller 
public class AppraisalFormatController { 
private AppraisalFormatService appraisalFormatService; 

@Autowired 
public void setAppraisalFormatService(AppraisalFormatService appraisalFormatService) { 
    this.appraisalFormatService = appraisalFormatService; 
} 



//Returning appraisal template list 
@RequestMapping(value = "/showAppraisalFormatList", method = RequestMethod.POST) 
public @ResponseBody List<AppraisalFormatMaster> showAppraisalFormatList() { 

    return appraisalFormatService.getAppraisalFormatList(); 
} 

// Showing appraisal template create form 
@RequestMapping("/createappraisalformat") 
public String createAppraisalFormat(Model model) { 

    model.addAttribute(new AppraisalFormatMaster()); 

    return "createappraisalformat"; 
} 


// Save or update data 
@RequestMapping(value = "/doCreateAppraisalFormat",method=RequestMethod.POST) 
public String doCreateAppraisalFormat(Model model,@RequestBody AppraisalFormatMaster appraisalFormatMaster) { 

    appraisalFormatService.create(appraisalFormatMaster); 

    for(AppraisalFormatDetail appraisalFormatDetail:appraisalFormatMaster.getAppraisalFormatDetailList()){ 
     appraisalFormatDetail.setAppraisalformatmaster(appraisalFormatMaster); 
     appraisalFormatService.createAppraisalFormatDetail(appraisalFormatDetail); 
    }  

    model.addAttribute("successMsg", "Data saved successfully !!"); 
    model.addAttribute("appraisalFormatMaster", new AppraisalFormatMaster()); 

    return "createappraisalformat"; 
} 



@RequestMapping(path="/showAppraisalFormatWithDetails/{id}", method=RequestMethod.POST, produces="application/json") 
public @ResponseBody List<AppraisalFormatMaster> getFormatWithDetails(@PathVariable Integer id,@RequestParam("id") int formatId){

我發現輸出時System.out來自控制器

AppraisalFormatMaster [id=41, formatName=Template for IT Department, formVersionNo=1, markVersionNo=1, createdBy=0, appraisalFormatDetailList=[AppraisalFormatDetail [id=19, appraisalHeads=1, appraisor=1,2], AppraisalFormatDetail [id=20, appraisalHeads=2, appraisor=1,2], AppraisalFormatDetail [id=21, appraisalHeads=3, appraisor=1,2], AppraisalFormatDetail [id=22, appraisalHeads=4, appraisor=3,4]]]

但是我發現在$.post()方法

[{"id":41,"formatName":"Template for IT Department","formVersionNo":"1","markVersionNo":1,"createdBy":0}]

的pom.xml輸出10

你需要顯示控制器功能的更多細節，以便任何人給你任何想法。 – Naros

我編輯了我的任務。請看這個。我被困在這裏。 –

您沒有任何對JavaScript端的詳細記錄，因爲你有收集@JsonIgnore您AppraisalFormatMaster類中。
