【From the technology and the Tao】Api contract quantum entanglement technique: 11-dimensional communication protocol in response to encapsulation [Development log of AI2077 in artificial intelligence retardation 012]

summary: In the quantum chaos of API communication, 30+ return formats collide with each other like the laws of physical laws of parallel universes. The eleven-dimensional communication protocol built in this paper realizes a quantum transition from data collapse to standardized symmetry through triple-dimensional stabilization devices of space-time anchor point (ApiResult), quantum filter (ResponseWrapper) and annihilation shield (Jackson configuration). Finally, a superstring channel was set up between code specifications and the laws of the universe, so that carbon-based developers could reach a cross-dimensional dialogue with silicon-based systems, use entropy reduction mechanisms to combat interface corruption, use causal laws to protect abnormal propagation, and reshape the basic communication law of the digital world.

Current status of quantum entanglement (technical background)

After completing the quantum deployment ceremony (see Development Log 010), we are facing the oldest philosophical proposition in the history of software development: how to make carbon-based organisms have an effective dialogue with silicon-based systems. There are three cosmic pain points in the current API communication field:

1. Data dimension collapse: The original return object is like an unpacked quantum bubble, which may cause client parsing confusion at any time
2. Missing law of cause and effect: Exception information is propagated in an irregular manner in the space-time continuum (calling link)
3. Protocol symmetry breaks: The return format of different developers is like the physical laws of parallel universes

These pain points cause each interface call to be like sending coordinate broadcasts in a dark forest. This article will build a quantum communication protocol based on ApiResult to realize standardized information exchange across dimensions.

Dark Forest Law (Note Extensions)

The eleven-dimensional trap to avoid

1. Naked string black hole: Unencapsulated String type swallows the surrounding JSON structure
2. Timeline pollution: Swagger document interface is accidentally encapsulated, resulting in overlapping dimensions
3. Type annihilation reaction: Long type has accuracy loss in JavaScript horizon

Two-way foil protection

1. Response wrapper: Build a spatiotemporal stable anchor point (ApiResult)
2. Quantum filter: Use regular expressions to build protective force fields
3. Type converter: Inject dimensional stabilizer at the space-time fold (HttpMessageConverter)

The eleventh-dimensional traps to avoid:

• Protocol tore the black hole: Unfiltered /swagger interface encapsulation will cause the document system to crash
• Monitoring signal annihilation: Prometheus cannot collect metrics after the actuator endpoint is encapsulated

Two-way foil protection supplement:

• Quantum whitelist: Build a space-time firewall through regular expressions
• Annotation of the law of cause and effect: @IgnoreResultPackage Like dimensionality reduction foil, locally maintains the 2D communication protocol

Dimension folding (implementation steps)

Curvature I: Building a quantum communication protocol

@Getter
 public class ApiResult<T> {
     private Integer code; // Status code (cosmic civilization level)
     private T data; // Payload (quantum foam)
     private String message;// Civilized broadcast (readable information)
     private LocalDateTime timestamp; // Cosmic Era
 }

Develop a small theater
Master: "Why do you need to make such a complicated packaging? Isn't it okay to directly return data?"
Artificial Intellectual Retard: "Of course! If you want the client to parse and return results like interpreting Maya text, I will delete all the encapsulation logic."

Curvature II: Install quantum filter

@RestControllerAdvice
 public class ResponseWrapper implements ResponseBodyAdvice<Object> {
     // Build a stargate whitelist
     private static final List<String> STAR_GATES =
         ("/swagger.*", "/v2/api-docs", "/actuator.*");
    

     @Override
     public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
         //Filter the swagger interface directly first
         if(().getName().contains("springdoc")){
             return false;
         }
         // Mark the interface to be filtered on the filter interface
         return !();
     }

     @Override
     public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType, Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request, ServerHttpResponse response) {

         // If it is already ApiResult type, it will not be processed
         if (body instanceof ApiResult) {
             return body;
         }
         // Avoid contamination of swagger object return
         if (ignored(().getRawPath())) {
             return body;
         }
         // Wrapping the original return value as ApiResult
         return (body);
     }

 }

Quantum annihilation protection (technical principle)

Technical metaphor：
Ignoring the packet mechanism is like installing a dimension filter in a quantum communication protocol, which is used to:

1. Prevent parallel universe pollution (avoid document interfaces such as swagger being accidentally encapsulated)
2. Keep the original space-time cracks (compatible with interfaces that require direct output of the original format)
3. Avoid the law of causality paradox (some monitoring endpoints must remain in a specific format)

Develop a small theater：
Master: "Why did the Swagger document turn into a quantum bubble?"
Artificial Intelligence Retardant: "Because you did not install a dimension filter! Now each interface response contains three layers of space-time bubbles, and the swagger parser has been lost in eleven-dimensional space!"

Curvature III: Overcoming type annihilation

@Configuration
 public class ResponseJsonConfiguration implements WebMvcConfigurer {


     @Bean
     @Primary
     @ConditionalOnMissingBean()
     public ObjectMapper jacksonObjectMapper(Jackson2ObjectMapperBuilder builder)
     {
         ObjectMapper objectMapper = (false).build();

         // Set the mapper object through this method, and all serialized objects will be serialized according to the change rules
         //  default
         // The Include.NON_DEFAULT property is the default value and is not serialized
         // If the Include.NON_EMPTY property is empty ("") or NULL and is not serialized, the returned json does not have this field.  This will save more traffic on mobile devices
         // The Include.NON_NULL property is NULL and not serialized
         // (.NON_EMPTY);
         (DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

         // Single quotes are allowed
         (.ALLOW_SINGLE_QUOTES, true);
         SimpleModule simpleModule = new SimpleModule();
         (, );
         (, );
         (, );
         (simpleModule);

         return objectMapper;

     }

     @Override
     public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {
         (mappingJackson2HttpMessageConverter);
         (1, mappingJackson2HttpMessageConverter);
     }
 }

Technical metaphorical explanation
This configuration is equivalent to establishing an energy level transition channel between the JSON universe and the String dimensions, ensuring that the encapsulator prioritizes processing of quantum data

Space-time verification (verification process)

Density detection: Basic communication test

Scene 1: Return plain text (not enclosed)

@IgnoreResultPackage // Skip the package
 @GetMapping("/text")
 public String rawText() {
     return "Hello,World"; // Direct output string
 }

Scenario 2: Return the string of the JSON packet

@GetMapping("/message")
 public ApiResult<String> wrappedMessage() { // explicitly declare generics
     return ("Operation successful");
     // Response result: {"code":200, "data":"Operation successful", ...}
 }

Verification operation

# Send quantum detection request
 curl -X GET -H "Accept:*/*" -H "Content-Type:application/x-www-form-urlencoded" "http://localhost:57510/rest/v1/front/home/hello"

 # Expected response
 {
   "code": 200,
   "data": "Hello World!",
   "message": "Success",
   "timestamp": "2025-03-10T17:02:13.496496825"
 }

Technical principles comparison table

Density detection: abnormal event simulation

@GetMapping("/black-hole")
 public void triggerSingularity() {
     throw new QuantumFluctuationException("Spatial time curvature exceeds the critical value");
 }

 // Exception handler
 @ExceptionHandler()
 public ApiResult<Void> handleException(QuantumFluctuationException ex) {
     return (500, ());
 }

# Trigger the singularity event
 curl -X GET http://localhost:9980/api/black-hole

 # Expected response
 {
   "code": 500,
   "data": null,
   "message": "The curvature of time and space exceeds the critical value",
   "timestamp": "2077-12-10T23:59:60"
 }

Cyberspace (Philosophical Thinking)

In the process of building API communication protocols, we are actually creating the digital worldBasic Laws of the Universe. Each ApiResult object carries specification informationGravitational, and ResponseWrapper maintains cosmic orderHiggs Field. This design concurs with the following cosmic truths:

1. The principle of symmetry: The unified response format maintains the normative symmetry of different dimensions (server/client)
2. Causal law protection: The clear error code establishes a reliable causal link
3. Entropy reduction mechanism: Standardized structure effectively resists the entropy increase caused by interface corruption

When we encapsulate all the returned results in ApiResult, we are actually creatingQuantum communication bubble——Each response carries complete meta information and maintains structural stability when crossing the cyberspace. This design allows clients to not guess the state of the server, just as civilizations in the universe do not need to rediscover the laws of physics.
