How to convert html to jsp

HTML web page is a static web page file. The content it displays to the user is fixed and cannot change in real time with the user's operation and input. JSP (Java Server Pages) is a dynamic web page technology that can embed Java code into web pages on the server side and generate different HTML web page content in real time based on user actions and inputs. When developing websites, converting static HTML web pages into dynamic JSP web pages is a common operation. The methods and steps for converting HTML into JSP will be introduced in detail below.

1. Understand the basic syntax of HTML and JSP

Before converting HTML to JSP, you need to first understand the basic syntax and characteristics of HTML and JSP. HTML is a markup language that uses tags to describe various elements in web pages, such as paragraphs, tables, images, etc. JSP is a Java technology that generates dynamic HTML web page content through Java code.

In HTML code, elements are surrounded by tags, as shown below:

<p>这是一段文本</p>

In JSP code, use to include Java code, as shown below:

At the same time, the JSP code can also obtain user-requested data and server-side information through built-in objects, as shown below:

2. Change the HTML file to a JSP file

First you need to change the original HTML file to a JSP file and change the suffix name to .jsp. This way the server knows that the file needs to be parsed and processed using JSP technology. For example, the original HTML file is index.html, and the modified JSP file is named index.jsp.

3. Convert HTML code to JSP code

1. Copy HTML code

Select the HTML file to be converted, open a text editor, and copy the HTML code in it to the clipboard.

2. Create a JSP file

In the Web application development tool, select the target folder to convert the HTML file, create a new JSP file, and name it the same as the original HTML file.

3. Convert HTML code to JSP code

Paste the HTML code you just copied into the clipboard into the JSP file. Add Java code and JSP tags to the code to turn it into JSP code, as shown below:

    <title>Hello World</title>


<h1 id="Hello-World">Hello World!</h1>

Use the tag to declare the relevant attributes of the JSP page, such as the character encoding used by the page , the language type of the JSP page, etc.

Use the tag to include Java code to dynamically generate HTML. In the above example, the JSP page obtains the request parameter name and outputs it to the HTML page.

4. Modify the JSP page link

If the original HTML page contains tags that link to other pages, you need to modify the links of these tags to links to the JSP page, for example, change the link is changed to Link. This can ensure that the entire web page can run normally and use JSP technology to generate dynamic HTML content.

Summary:

Converting static HTML web pages into dynamic JSP web pages can make the web page content change in real time according to the user's operations and input, improving the user's interactive experience. During the conversion process, you need to be familiar with the syntax of HTML and JSP, convert HTML code to JSP code, and modify JSP page links to correct links. Through these steps, you can successfully convert HTML web pages into JSP web pages and achieve the purpose of dynamically generating HTML content.
