Question

我需要使用jquery从视图向spring mvc控制器发送数据。 Spring mvc将在db中插入/更新这些值。我使用下面的代码

JQuery的：

 var json = {"KPI" : visual, "partnerName": params['partnerName'],
 "partnerAddress" : params['partnerAddress'], "documentType" : params['documentType'], 
 "itemQualifier": getItemQualifier(),"itemIdentifiers" : params['itemIdentifiers'], 
 "currency" : getCurrency(), "sellSide": getSellSide()};

 $.ajax({                                                                   
        type: "POST",
        url: "/reports/savefilters",
        data: json,
        success: function(response){
                 alert('success: ' + response);
                },
        error: function(e){ 
                 alert('Error: ' + e);
                }
 });

Spring MVC控制器代码：

@RequestMapping(value="/savefilters", method=RequestMethod.POST)
public String saveFilters(@RequestBody AnalyticsFilters filters){
    System.out.println("savefilters method in controller");
    System.out.println("KPI:"+filters.getKPI());
    if(filters.getPartnerName() != null && filters.getPartnerName().size()>0 ) System.out.println("partnerName:"+filters.getPartnerName().get(0));
    if(filters.getPartnerAddress() != null && filters.getPartnerAddress().size()>0 ) System.out.println("partnerAddress:"+filters.getPartnerAddress().get(0));
    if(filters.getDocumentType() != null && filters.getDocumentType().size()>0 ) System.out.println("documentType:"+filters.getDocumentType().get(0));
    System.out.println("itemQualifier:"+filters.getItemQualifier());
    if(filters.getItemIdentifiers() != null && filters.getItemIdentifiers().size()>0 ) System.out.println("itemIdentifiers:"+filters.getItemIdentifiers().get(0));
    System.out.println("currency:"+filters.getCurrency());
    System.out.println("sellSide:"+filters.getSellSide());
    new DashboardDisplayService().saveFilters();
    return "successful";
}

发布请求将转换为Get方法，无法访问spring mvc控制器。我尝试了不同的ajax json选项，如datatype，contenttype等。如何确保POST请求不会更改为GET方法???

Ajax方法返回ResponseBody中的消息。我修改了你的处理程序方法，如下所示。

@RequestMapping(value="/savefilters", method=RequestMethod.POST)
public @ResponseBody String saveFilters(@RequestBody AnalyticsFilters filters){
...
}

带有json数据的Jquery ajax请求没有到达spring mvc控制器
