控制器

Question

我是Spring框架的新手。我通过$.post()方法从视图页面发送请求，我的控制器从我的DAO类接收数据。但我没有得到完整的数据。我发布了我的源代码

$.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 ){

    System.out.println("showAppraisalFormatWithDetails......................");
    System.out.println("format id: " + formatId);

    for(AppraisalFormatMaster appraisalFormatMaster: appraisalFormatService.getFormatWithDetails(formatId)){

        System.out.println(appraisalFormatMaster);
        for(AppraisalFormatDetail appraisalFormatDetail:appraisalFormatMaster.getAppraisalFormatDetailList()){
            System.out.println(appraisalFormatDetail);
        }
    }


    return appraisalFormatService.getFormatWithDetails(formatId);
}

我在控制器

的System.out时找到了输出

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]]]

但是我在$.post()方法

中找到了输出

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

Answer 1

您在Javascript方面没有任何详细记录，因为@JsonIgnore课程内的集合上有AppraisalFormatMaster。

没有从spring控制器和jquery .post（）方法中获取正确的json
