XmlElement 在 SOAP 中显示为小写

如何解决XmlElement 在 SOAP 中显示为小写

public PingResponse ping(String xml) throws remoteexception {
    PingResponse response = new PingResponse();
    response.setPingResult("Service is Live");
    return response;
}

这是 PingResponse.java

@XmlRootElement(name = "PingResponse")
public class PingResponse implements java.io.Serializable {

    private String pingResult;

    @XmlElement(name = "PingResult")
    public String getPingResult() {
        return pingResult;
    }

    public void setPingResult(String pingResult) {
        this.pingResult = pingResult;
    }

我遇到的问题是我得到的 XML 响应的 pingResult 为小写。完整示例：

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soapenv:Body>
      <PingResponse>
         <pingResult>Service is Live</pingResult>
      </PingResponse>
   </soapenv:Body>
</soapenv:Envelope>

知道这里可能有什么问题吗？
