This article brings you what is the SpringBoot framework? The construction process of the SpringBoot framework has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
Introduction to Spring Boot
1. What is SpringBoot
1.1 Spring Boot is a new framework provided by the Pivotal team. It is designed to simplify the initial construction and development process of new Spring applications. The framework uses an ad hoc approach to configuration, eliminating the need for developers to define boilerplate configurations. In this way, Spring Boot is committed to becoming a leader in the booming field of rapid application development.
2. Advantages of SpringBoot
2.1 Removes a large number of xml configuration files
2.2 Simplifies complex dependency management
2.3 Use with various starters, Basically, automated configuration can be achieved
2.4 Quickly start the container
Create independent Spring applications, embedded Tomcat, Jetty containers, without deploying WAR packages, simplifying Maven and Gradle configuration (spring The entrance to the boot project is a main method, just run this method) (If you need to package it, you can directly package it into a jar package, and run java -jar ***.jar)3. The following application launcher is provided by Spring Boot under the org.spring framework
Spring Boot Building
We all know that in general projects, it is necessary to introduce many packages and many configuration files, which is the most frustrating What's more, in previous projects, it was not enough to just introduce packages, but also to avoid issues such as version conflicts. Generally speaking, it was quite a headache. Then in SpringBoot you no longer need to worry about package versions or missing packages, just a configuration SpringBoot will do it all for us. Let's take a look. Only one core dependency and web support SpringBoot is introduced. Will you help us import which packages? (The following are all the dependencies introduced by this demo)
1. pom.xml configuration
<!-- SpringBoot 核心依赖 --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.2.RELEASE</version> </parent> <!-- web 支持 --> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>1.5.9.RELEASE</version> </dependency> </dependencies>
2. Program startup entry (directly run the main method) Yes)
@SpringBootApplicationpublic class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
In order to facilitate testing, we add a Controller and Entity here
import org.springframework.http.MediaType; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import com.firstboot.lpx.entity.Person; @RestController public class MyController { @RequestMapping(value="/getPerson/{age}", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE) public Person getPerson(@PathVariable int age){ Person p = new Person(); p.setName("小李"); p.setAge(age); return p; } }
public class Person { private String name; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
3. Start the SpringBoot program and access the getPerson interface
#OK, the above is the small demo of SpringBoot.

JVM handles operating system API differences through JavaNativeInterface (JNI) and Java standard library: 1. JNI allows Java code to call local code and directly interact with the operating system API. 2. The Java standard library provides a unified API, which is internally mapped to different operating system APIs to ensure that the code runs across platforms.

Platform independence in JavaGUI development faces challenges, but can be dealt with by using Swing, JavaFX, unifying appearance, performance optimization, third-party libraries and cross-platform testing. JavaGUI development relies on AWT and Swing, which aims to provide cross-platform consistency, but the actual effect varies from operating system to operating system. Solutions include: 1) using Swing and JavaFX as GUI toolkits; 2) Unify the appearance through UIManager.setLookAndFeel(); 3) Optimize performance to suit different platforms; 4) using third-party libraries such as ApachePivot or SWT; 5) conduct cross-platform testing to ensure consistency.

Java code will have performance differences when running on different platforms. 1) The implementation and optimization strategies of JVM are different, such as OracleJDK and OpenJDK. 2) The characteristics of the operating system, such as memory management and thread scheduling, will also affect performance. 3) Performance can be improved by selecting the appropriate JVM, adjusting JVM parameters and code optimization.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
