以json格式获取响应

Question

我已使用以下代码处理错误并将错误消息设置为响应

    String envelopeError = "<soapenv:Error xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
            + "     <Error_Message>" + errorMsg + "</Error_Message>\n"
            + "  </soapenv:Error>";
    OMElement myOMElement = null;
    try {
        myOMElement = AXIOMUtil.stringToOM(envelopeError);
        SOAPEnvelope soapEnvelope = TransportUtils.createSOAPEnvelope(myOMElement);
        messageContext.setEnvelope(soapEnvelope);
    } catch (XMLStreamException | AxisFault e) {
        log.error("Error occurred while handling failure: " + errorMsg, e);
    }

但是，当我发送错误的请求时，只有POST调用才能获得json格式的响应。 GET调用以文本形式获取响应。

我使用的示例命令如下：

POST命令：

curl -X POST \
  https://ipaddress:8243/postcall \
  -H 'Accept: application/json' \
  -H 'Authorization: Bearer 83fe925f-f054-3c27-bd7c-b9228aea48a0' \
  -H 'Content-Type: application/json' \
  -d '{ .... }'

GET命令：

curl -k -X GET "https://ipaddress:8243/getcall" 
  -H 'Accept: application/json' 
  -H "Authorization: Bearer 0ca12e9b-490a-3ca5-bc01-d24703e6fb9b" 
  -H 'Content-Type: application/json'
