Java language Web application development skills

The Java language is a very popular high-level programming language and is widely used in Web application development. This article will introduce some Java language Web application development techniques to help developers build efficient and reliable Web applications faster and better.

1. MVC Architecture

In Java language Web application development, using the MVC architecture is a very common practice. The MVC architecture divides web applications into three parts: Model, View and Controller. Model is responsible for data processing, View displays data, and Controller controls the flow of the page. This architecture can make the code clearer and easier to maintain.

2. ORM Framework

ORM framework (Object Relational Mapping) is a mapping tool between Java objects and relational database tables, which can make data operations easier and specifications. Currently popular ORM frameworks include Hibernate and MyBatis, and developers can choose according to their needs.

3. Intelligent caching

The intelligent caching technology of Java language can significantly improve the performance of web applications. When an application needs to frequently read and write resources such as databases and files, it can use intelligent caching technology to temporarily store the data in the cache. When it is needed next time, it can be read directly from the cache instead of reading from the disk or database. This can Greatly reduce disk or database I/O operations.

4. Interceptor

The interceptor in Java language web application refers to processing and modifying it through some means before the request reaches the controller or before the response reaches the browser. or the process of intercepting a request or response. Interceptors can be used in scenarios such as request parameter verification, permission management, and logging. When using the Spring MVC framework, you can implement these functions by writing interceptors.

5. Asynchronous processing

Asynchronous processing in Java language Web applications can improve system performance and access throughput. In web applications, different requests can be processed concurrently to avoid long wait times for requests, resulting in performance degradation. After Java EE 7, Java API for WebSocket (JSR 356) provides a new asynchronous processing method that can greatly improve the performance of web applications.

6. Security Technology

In Java language Web applications, attention should be paid to ensuring the security of the system, which includes preventing cross-site scripting attacks, injection attacks, authentication, and authorization wait. You can use the Spring Security framework for authentication and authorization management, and you can also use verification codes and current limiting to prevent malicious attacks.

7. RESTful service

RESTful service is a Web service based on HTTP protocol. In the Java language, the Spring MVC framework can be used to implement RESTful services. An important feature of RESTful services is that they meet the semantics of the HTTP protocol, which can make Web services more flexible, easy to use, and scalable.

Summary:

Java language is a programming language that is very suitable for web application development. It can use MVC architecture, ORM framework, smart caching, interceptors, asynchronous processing, security technology, and RESTful services. and other technologies to improve the efficiency and stability of Web applications. Through these technologies, efficient and reliable web applications can be developed faster. If you're not already using these techniques, I recommend you start trying them out.
