SpringBoot @PostMapper 接收HTTP 请求的流数据方式

@PostMapping("/test")
public String pushMessage(@RequestBody byte[] data) throws Exception {
    String json = URLDecoder.decode(new String(data, DEFAULT_CHARSET), DEFAULT_CHARSET);
    log.info(">>> 接收CP推送的消息：{}", json);

    JSONObject jsonObject = JacksonUtils.jsonToBean(json, JSONObject.class);

         System.out.println(jsonObject.get("key"));

         return “success”

}

Client 请求

    connection.connect();

    //POST请求
    DataOutputStream out = new DataOutputStream(connection.getOutputStream());

    JSONObject data = new JSONObject();
    data.element("key", "这是一条测试数据");
    
    out.writeBytes(data.toString());
