Spring @RequestBody 覆盖

Question

我有一个 Spring 控制器，它可以接收帖子并且它可以工作。唯一的问题是我们的 SMS 提供商将向我们发送包含首字母大写的键的标头，例如：

 {
"FromPhoneNumber":"15177754077",
"ToPhoneNumber":"17572046106",
"ResponseReceiveDate":"7/29/2014 5:25:10 AM",
"Message":"PIN 1234"
}

Spring 会抛出如下错误：

    Could not read JSON: Unrecognized field "FromPhoneNumber" (class com.talksoft.spring.rest.domain.CDynePost), not marked as ignorable (4 known properties: "responseReceiveDate", "toPhoneNumber", "fromPhoneNumber", "message"])

所以，我必须有一种方法来覆盖这种行为。这是处理 CDyne 帖子的控制器方法：

    @RequestMapping(method = RequestMethod.POST, value="/celltrust")
    public ResponseEntity<String> cellTrustPost(@RequestBody CDynePost cDynePost) {
        String message = "FAILED";
        UserInteraction userInteraction = getUserInteraction(cDynePost);
        boolean success = someSpringService.logMessage(userInteraction);

        if (success) {
            message = "OK";
            return new ResponseEntity<String>(message, HttpStatus.ACCEPTED);
        } else {
            return new ResponseEntity<String>(message, HttpStatus.FAILED_DEPENDENCY);
        }       

    }

这里是 CDynePost 类：

public class CDynePost {
    private String FromPhoneNumber;
    private String ToPhoneNumber;
    private String ResponseReceiveDate;
    private String Message;

    public String getFromPhoneNumber() {
        return FromPhoneNumber;
    }
    public void setFromPhoneNumber(String FromPhoneNumber) {
        this.FromPhoneNumber = FromPhoneNumber;
    }
    public String getToPhoneNumber() {
        return ToPhoneNumber;
    }
    public void setToPhoneNumber(String ToPhoneNumber) {
        this.ToPhoneNumber = ToPhoneNumber;
    }
    public String getResponseReceiveDate() {
        return ResponseReceiveDate;
    }
    public void setResponseReceiveDate(String ResponseReceiveDate) {
        this.ResponseReceiveDate = ResponseReceiveDate;
    }
    public String getMessage() {
        return Message;
    }
    public void setMessage(String Message) {
        this.Message = Message;
    }
}   

我查看了 ObjectMapper，但我不确定如何在我的控制器中使用它，而且说实话，如果 Spring 可以免费编写的话，我宁愿不必编写一堆额外的类。

只需使用 @JsonProperty 注释您的字段、getter 或 setter，指定将出现在 JSON 中的确切名称。例如

@JsonProperty("FromPhoneNumber")
private String FromPhoneNumber;
