在wso2 esb类中介中,我得到空的请求 .

公共类HandleJSONPayload扩展AbstractMediator {

public boolean mediate(MessageContext context) {
        try {
            org.apache.axis2.context.MessageContext axis2MessageContext = ((Axis2MessageContext) context).getAxis2MessageContext();
            JSONObject jsonPayload = new JSONObject(JsonUtil.jsonPayloadToString(axis2MessageContext));
**System.out.println("o/p--------->"+jsonPayload.toString());**

            //setting the payload as the message payload
            JsonUtil.getNewJsonPayload(axis2MessageContext, jsonPayload.toString(), true, true);
        } catch (Exception e) {
            handleException("Error while mediating the message", e, context);
        }
        return true;
    }
}

我正在打印的o / p给出空的json({}) . 但在许多文章中我发现这是获取信息的方式 .
