Java Web is the sum of technologies that use Java technology to solve related web and Internet fields. The web consists of two parts: web server and web client. Java applications on the client include Java applet, but rarely used, Java has a lot of applications on the server side, such as Servlet, JSP and third-party frameworks, etc. The development of Java technology in the Web field Injected strong motivation.
Recommended course: Java Tutorial.
Although Java's Web frameworks are different, they basically follow a specific approach: use Servlet or Filter to intercept requests, and use MVC ideas to design the architecture. Use approx. Define, XML or Annotation to implement configuration, use the object-oriented characteristics of Java, implement the object-oriented process of request and response, and support Jsp, Freemarker, Velocity and other views.
JSP advantages:
Java EE standard, which means there is great market demand and more job opportunities
Get started quickly and relatively Easy
There are a large number of available component libraries
JSP Disadvantages:
A large number of JSP tags
No support for REST and security Well
There is no unified implementation. There are both SUN implementations and Apache implementations - MyFaces.
Advantages of Spring MVC:
Provides life cycle management for Spring MVC overriding binding, validation, etc.
And many Seamless integration of presentation layer technologies/frameworks: JSP/JSTL, Tiles, Velocity, FreeMarker, Excel, :
Lots of XML configuration filesToo flexible - no public parent controller
No built-in Ajax supportStripes Advantages:
No need to write XML configuration filesGood learning documentation
Community members are very enthusiasticStripes Disadvantages:
The community is relatively smallNot as active as other projects
The URL in ActionBean is hard-codedStruts 2 Advantages:
Simple architecture - easy to extendThe tag library is easy to use FreeMarker or Velocity to customize
based on controllers or Page-based navigationStruts 2 Disadvantages:
Poorly organized documentationExcessive focus on new features
Tapestry Advantages:
Once you learn it, you will greatly improve your productivityHTML template - very beneficial to page designers
Every time a new version is released, There will be a lot of innovationTapestry Disadvantages:
The document is too conceptual and not practical enoughThe learning curve is steep
Release cycle Long - there are major upgrades every yearWicket advantages:
Good for Java developers (not Web developers)Page and Show binding is tight
Active community - with support from the creatorWicket Cons:
HTML templates and Java code are right next to each otherNeed to have a good understanding of OO
Wicket logic - everything is done in JavaThe above is the detailed content of What is Java Web. For more information, please follow other related articles on the PHP Chinese website!

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.

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.
