Editor to share with you what are the advantages of JSP, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Advantages of JSP:

1. Separate the generation and display of content

Using JSP technology, Web page developers can use HTML or XML logos to design and format the final page. Use JSP logos or small scripts to generate dynamic content on the page. The logic for generating content is encapsulated in identity and JavaBeans components and bundled in small scripts, all of which run on the server side. If the core logic is encapsulated in logos and Beans, then others, such as Web managers and page designers, can edit and use JSP pages without affecting content generation.

On the server side, the JSP engine interprets the JSP logo and small scripts, generates the requested content (for example, by accessing JavaBeans components, using JDBCTM technology to access the database, or includes files), and sends the results back to the browser as a HTML (or XML) page. This helps authors protect their code while ensuring the full availability of any HTML-based Web browser.

2. Emphasize reusable components

Most JSP pages rely on reusable, cross-platform components (JavaBeans or Enterprise JavaBeansTM components) to perform the more complex processing required by the application. Developers can share and exchange components that perform common operations, or make them available to more users or customer groups. The component-based approach accelerates the overall development process and allows organizations to balance their existing skills and development efforts to optimize results.

3. Use logo to simplify page development

Web page developers are not all programmers who are familiar with scripting languages. JavaServer Page technology encapsulates many functions that are needed for dynamic content generation in easy-to-use, JSP-related XML identifiers. The standard JSP logo can access and instantiate JavaBeans components, set or retrieve component properties, download Applet, and perform functions that are more difficult to code and time consuming in other ways.

Through the development of customized identification libraries, JSP technology can be extended. In the future, third-party developers and others can create their own identity libraries for common functions. This allows Web page developers to work with familiar tools and artifacts that perform specific functions like identifiers.

JSP technology can be easily integrated into a variety of application architectures to take advantage of existing tools and skills, and extended to support enterprise-level distributed applications. As part of the Java technology family and part of Java 2 (Enterprise Edition Architecture), JSP technology can support highly complex Web-based applications.

Because the built-in scripting language for JSP pages is based on the Java programming language, and all JSP pages are compiled into Java Servlet,JSP pages, it has all the benefits of Java technology, including robust storage management and security.

As part of the Java platform, JSP has the characteristics of the Java programming language "write once, run everywhere". As more and more vendors add JSP support to their products, you can use the server and tool of your choice, and changing the tool or server does not affect the current application. The advantage of JSP is very obvious.

Scope of application

Because Apache is widely used in NT, Unix and Linux, JSP has a wider range of operating platforms. Although the NT operating system occupies a large market share, but the advantage of Unix in the server is still great, and the new rise of Linux is not small. Migrating from one platform to another, JSP and JavaBean don't even have to recompile, because Java bytecode is standard and platform-independent.

Performance comparison

Some people have done experiments to test the cycle performance of the three languages of ASP,PHP,JSP and to access the Oracle database.

In the loop performance test, JSP ended the 20, 000-20, 000 cycle in an amazing four seconds. ASP and PHP tested 2000 cycles (an order of magnitude less) in 63 seconds and 84 seconds, respectively. (see PHPLIB).

In the database test, the three Insert,Update,Select Oracle 8 1000 times, and it takes 13 seconds for Delete: Jsp, 69 seconds for Php, and 73 seconds for ASP. The advantage of JSP in terms of performance is also very obvious.

Prospect analysis

At present, PHP and ASP are the most widely used in China. However, because ASP.NET JSP is a relatively new technology, it is seldom used in China. ASP.NET is also slowly increasing. But in foreign countries, JSP has been a more popular technology, especially e-commerce websites, mostly use JSP.

Among the four, JSP,PHP,ASP.NET has a very good application prospect. JSP also has a lot of room for growth because of its security and operational efficiency.
