Java 正在尝试通过列表<；T>；使用springmvc的in-post方法？

java rest spring-mvc spring-boot

Java 正在尝试通过列表<；T>；使用springmvc的in-post方法？,java,rest,spring-mvc,spring-boot,Java,Rest,Spring Mvc,Spring Boot,尝试使用SpringBootMVC在post方法中传递List，我尝试将json数组传递给RESTAPI，RESTAPI接受List，但它表示请求正文的格式不正确这是我正在传递的JSON格式 [{"quotation":100001,"customer":"ZOMRAN KHALED MEDICAL UNIT", "currency":"Algerian dinar (DZD)","country":"Algeria","language":"English", "product":"

尝试使用SpringBootMVC在post方法中传递List，我尝试将json数组传递给RESTAPI，RESTAPI接受List，但它表示请求正文的格式不正确

这是我正在传递的JSON格式

[{"quotation":100001,"customer":"ZOMRAN KHALED MEDICAL UNIT",
  "currency":"Algerian dinar (DZD)","country":"Algeria","language":"English",
  "product":"9100C","modality":"LCS","subModality":"ARC","services":"PM,CM",
  "serviceType":"SWIFT","price":"1500","responseTime":"24H","createdTime":"24/04/2018"},

  {"quotation":100002,"customer":"ZOMRAN KHALED MEDICAL UNIT",
  "currency":"Algerian dinar (DZD)","country":"Algeria","language":"English",
  "product":"9100C","modality":"LCS","subModality":"ARC","services":"PM,CM",
  "serviceType":"SWIFT","price":"1500","responseTime":"24H","createdTime":"24/04/2018"}
  ]

这是我捕获数组的Java控制器

@RequestMapping(value = "/carePlanQuotationHistory", method = RequestMethod.POST, produces = {
        MediaType.APPLICATION_JSON_VALUE, MediaType.TEXT_PLAIN_VALUE })
public @ResponseBody Response CarePlanQuotationHistory1(@RequestBody List<CarePlanHistoryRequest> carePlanQuotationHistory1) throws Exception {
    int a;
    try {
        a = productService.CarePlanQuotationHistory1(carePlanQuotationHistory1);

    } catch (Exception ex) {
        return new Response("400", ex.getMessage());
    }
    return new Response("200", a);
}

这是我们得到的错误

    "timestamp": 1526647767010,
    "status": 400,
    "error": "Bad Request",
    "exception": "org.springframework.http.converter.HttpMessageNotReadableException",

看起来您传递的JSON格式不正确。您已将引号定义为字符串，但仍将其作为数值传递。我建议将引号更改为整数，或者在将其作为JSON传递时将其值包装在引号中。

也发布pom.xml。错误说明了

客户

类，可以显示它吗？乍一看，似乎

引号

应该是一个数字而不是字符串。因此，要么在值

“quote”：“100001”

中添加引号，要么将类型更改为int或其他数字类型。您做错了什么。您的异常涉及

com.careplan.springbootstarter.entity.Customer，但我在您的代码中找不到该类。
