A RESTful web service written based on JAX-WS that returns xml documents. This xml document can be generated based on JAXB annotations, simplifying xml generation. In order to use the dependent libraries, you can add the following dependencies in the pom.xml file of the maven project: <dependency> <groupId>jakarta.xml.ws</groupId> <artifactId>jakarta.xml.ws-api</artifactId> <version>4.0.0</version> </dependency> <dependency> <groupId>com.sun.xml.ws</groupId> <artifactId>jaxws-rt</artifactId> <version>4.0.0</version> […]

Mybatis creation return object exception caused by Lombok’s @Builder annotation
Mybatis creation return object exception caused by Lombok’s @Builder annotation **Conclusion:** After using the Bbuilder annotation, a fully parameterized constructor will be produced based on the current class (excluding the attributes of the parent class). Mybaitis will cause many strange exceptions when it attributes the returned data, so it is best not to use it. […]
Simple HTTP service to implement random return of directory pictures and HTML to implement Web page design (experiment summary)
1. HTTP service for returning random pictures Implement the configuration environment: python, flask package (install with pip command or directly search for it in the ide and install it directly) Create a flask project directly in python and put the code from flask import Flask app = Flask(__name__) import os import random from flask import […]
re Pengcheng Cup returns in 2023
Secure programming: It’s rust, and I don’t really want to look at it and debug it. Open 010 and find that it is more regular. Try XOR with the png header to get the key 128. XOR out the picture badpe: I have never seen the idea of this question before, but it can be […]

Analysis of the core binary search method in jdk 4.1 Why low is the insertion point 4.2 Why negation is necessary: – (low + 1) 4.3 Why not directly return the opposite […]
5. Deep copy and shallow copy + return value optimization
Deep copy and shallow copy + return value optimization Concept In C++, deep copy and shallow copy are two different methods of object copying, and they show different behaviors when dealing with dynamically allocated memory. Shallow Copy: Shallow copy refers to copying the value of the data member of one object to another object, but […]
C++ uses boost to implement an asynchronous thread pool with return values and input parameters
Preface Thread pools have some advantages over simple multi-threading: 1. The thread pool will automatically allocate work to an idle worker thread for execution, which is better than multi-thread execution in batches; 2. The thread pool only needs to be created once. The creation and destruction of multiple threads when used multiple times will cause […]

[Multi-threading] Thread control {thread creation, thread exception, program replacement in multi-threads; thread waiting, parameters and return values of thread entry functions; thread termination, thread ID, thread attribute structure, thread independent stack structure, thread local Variables; thread separation; pthread library functions}
1. Thread creation 1.1 pthread_create function The pthread_create() function is a function used to create threads. It belongs to the pthread thread library (POSIX thread library). The function prototype is as follows: #include <pthread.h> int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine) (void *), void *arg); Parameter Description: thread: Pointer to pthread_t type, used to […]
