Spring @RequestBody覆盖

Question

我有一个Spring控制器，可以接收帖子，并且可以正常工作。 唯一的问题是，我们的SMS提供商将向我们发送标头，该标头包含带有大写首字母的密钥，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"])

因此，我必须有一种方法来替代此行为。 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;
    }
}   

我已经看过ObjectMapper了，但是我不确定如何在控制器中使用它，并且说实话，如果Spring免费提供它，我宁愿不必编写一堆额外的类。

只需使用@JsonProperty注释字段，getter或setter， @JsonProperty指定将在JSON中显示的确切名称。 例如

@JsonProperty("FromPhoneNumber")
private String FromPhoneNumber;
