Java Spring启动JSON Post 400错误

我无法将JSON数组发布到Spring Boot@RequestMapping Rest控制器。收到400个错误请求。有什么建议可以纠正吗

JQuery.ajaxPost

var sData = ["15957.028", "16356.175", "16937.155", "17564.315", "17942.480", "17760.259", "16572.306", "16746.408", "17339.681", "17946.216"] 

$.ajax({
    type: "POST",
    url: "/regression", 
    data: JSON.stringify({"sdata": sData}),
    contentType: 'application/json',
    headers: { 'X-CSRF-Token': token },
    error: function(jqXHR, textStatus, errorThrown) {
          console.log(textStatus, errorThrown, jqXHR.error());
    },
    success: function(){

    }
});

@RestController

@RequestMapping(value="/regression", method = RequestMethod.POST)
public HashMap<String, String> results(@RequestBody List<String> series )  {

    HashMap<String, String> results = new HashMap<String, String>();

    return results;

}

您需要将列表包装到另一个类中，如下所示

class SeriesWrapper{
  @Getter @Setter private List<String> series;
}

---

您尝试发布的sData不是JSON格式，您尝试将其发布为JSON

data: JSON.stringify({"sdata": sData}),
    contentType: 'application/json',

因此出现400错误

正确的JSON格式示例：

{ "firstname" : firstname, "lastname" : lastname, "email": email, "phone": phone, "company": company};

你从弹簧日志中得到了什么？有线索吗？无论如何，您可能需要一个包装器对象，因为您传递的json是一个包含Java端的array propertyNo错误的对象。我确实尝试使用显式类，但结果相同。尝试从jquery传递：

data:sData

var sData = {series : ["15957.028", "16356.175", "16937.155", "17564.315", "17942.480", "17760.259", "16572.306", "16746.408", "17339.681", "17946.216"]};

data: JSON.stringify({"sdata": sData}),
    contentType: 'application/json',

{ "firstname" : firstname, "lastname" : lastname, "email": email, "phone": phone, "company": company};
