pb协议 jdk序列化协议

1 pb协议

协议由序列化容量，jdk pb json kryo

server：

使用spring boot

	// 将服务器容器http body序列化方式指定为pb
		/**
		 * protobuf 序列化
		 */
		@Bean
		ProtobufHttpMessageConverter protobufHttpMessageConverter() {
			return new ProtobufHttpMessageConverter();
		}

		/**
		 * protobuf 反序列化
		 */
		@Bean
		RestTemplate restTemplate(ProtobufHttpMessageConverter protobufHttpMessageConverter) {
			return new RestTemplate(Collections.singletonList(protobufHttpMessageConverter));
		}

 

这两个bean告诉springboot，使用pb序列化

@Controller
@RequestMapping("/pb")
public class PbController {

    @RequestMapping(value = "/test", produces = "application/x-protobuf")
    @ResponseBody
    public MyBaseProto.BaseProto getPersonProto(@RequestBody MyBaseProto.BaseProto request) {

        MyBaseProto.BaseProto.Builder builder = MyBaseProto.BaseProto.newBuilder();
        builder.setCode(request.getCode() + 1);
        builder.setMsg(request.getMsg() + "back");
        System.out.println(request.getCode() + request.getMsg());
        return builder.build();
    }
}

 

client：

 java.net.URL object = new URL("http://127.0.0.1:8080/pb/test");
            HttpURLConnection con = (HttpURLConnection) object.openConnection();
            con.setDoOutput(true);
            con.setDoInput(true);

            // 此句必须，否则默认application/x-www-form-urlencoded;charset=UTF-8
            // */*也不行，服务器spring boot不认
            con.setRequestProperty("Content-Type", "application/x-protobuf");

            // 此句可省略
//            con.setRequestProperty("Accept", "application/x-protobuf");

            // 此句可省略
//            con.setRequestMethod("POST");

            // json协议，本文不用
            /**
            JSONObject data = new JSONObject();
            JSONObject tel = new JSONObject();
            tel.put("nationcode", nationCode);
            String phone = phoneNumber;
            tel.put("phone", phone);
            data.put("type", "0");
            data.put("msg", content);
            String sig = stringMD5(APPKEY.concat(phone));
            data.put("sig", sig);
            data.put("tel", tel);
             */

            // pb协议，自定义http协议
            MyBaseProto.BaseProto.Builder builder = MyBaseProto.BaseProto.newBuilder();
            builder.setCode(1);
            builder.setMsg("test");
            byte [] pb = builder.build().toByteArray();
            OutputStream wr = con.getOutputStream();
            wr.write(pb);
            wr.flush();

            // 显示 POST 请求返回的内容
            StringBuilder sb = new StringBuilder();
            int HttpResult = con.getResponseCode();
            if (HttpResult == HttpURLConnection.HTTP_OK) {
                InputStream inputStream = con.getInputStream();
                ByteArrayOutputStream result = new ByteArrayOutputStream();
                byte[] buffer = new byte[1024];
                int length;
                while ((length = inputStream.read(buffer)) != -1) {
                    result.write(buffer, 0, length);
                }
                MyBaseProto.BaseProto baseProto = MyBaseProto.BaseProto.parseFrom(result.toByteArray());
                System.out.println(baseProto.getCode() + baseProto.getMsg());

            } else {
                System.out.println("http error");
            }
