What does jsp mean?

jsp belongs to the backend. The essence of jsp is a servlet, and servlet is a server-side java application, so jsp is a back-end technology. JSP is deployed on the web server and can respond to requests sent by the client and dynamically generate web pages of HTML, XML or other format documents based on the request content, and then return them to the requester. JSP technology uses Java as a scripting language to provide services for user HTTP requests, and can handle complex business requirements together with other Java programs on the server.

The difference between jsp and html: 1. Operating mechanism; 2. Purpose; 3. Relationship with Java; 4. Function; 5. Relationship with back-end; 6. Speed; 7. Maintainability and scalability; 8. Learning and use Difficulty; 9. File suffixes and identification tools; 10. Community and support; 11. Security. Detailed introduction: 1. Operating mechanism. HTML is a markup language, mainly used to describe and define the content of web pages. It runs on the client and is interpreted and executed by the browser. JSP is a dynamic web page technology that runs on the server side, etc. wait.

After the new springboot project is created, the directory is as follows: Step 1: Add the jar package code required to configure jsp to the project's pom file: org.apache.tomcat.embedtomcat-embed-jasperprovided Step 2: Create a new directory webapp under the main path , create a new path WEB-INF under webapp, create a new path jsp under WEB-INF, and place the jsp file we want to use under this path. Step 3: Configure the access path and suffix code of the jsp file in the main configuration file: spring .mvc.view.prefix=/WEB-INF/jsp/sp

Implementation steps: 1. Introduce the JSTL tag library into the JSP page; 2. Obtain data from the database; 3. Paging the data; 4. Display the paging navigation bar in the page; 5. Display the number according to the current page number and each page. , just get the corresponding data from the paging data and display it on the page.

1. The core sql statement to implement paging query (1) The sql statement to query the total number of records in the database: selectcount(*)from+(table name); (2) The sql statement to query the number of records for each query: where: 0 is searched Index, 2 is the number of items searched each time. select*from table name limit0,2; 2. Code implementation* I wrote these two classes in the previous article, DBconnection class: used to obtain database connections, Author object class. Click on the link to view the code for these two classes. Click the link to view the DBconnection class and Author object class (1) Login page: index.jsp. Inserttitlehere user column

​JSP is a dynamic web technology standard. Its file format is to insert Java program segments (Scriptlet) and JSP tags (tags) into traditional web page HTML files (.htm, .html) to form JSP files (*.jsp ).

Can JSP be replaced by PHP? JSP (JavaServerPages) and PHP (HypertextPreprocessor) are commonly used server-side scripting languages ​​for dynamically generating web page content. Although they each have their own characteristics and advantages, can they completely replace each other in practical applications? This article will analyze the advantages and disadvantages of the two and compare them through specific code examples. First, let's take a look at the respective characteristics of JSP and PHP. JSP is a Java-based

Can PHP replace the functionality of JSP? As web development technology continues to evolve, developers are often faced with choosing the appropriate server-side language to implement their project needs. In this regard, PHP and JSP are two common choices. JSP is the abbreviation of JavaServerPages, which is a server-side technology based on Java, while PHP is a server-side scripting language. This article will explore whether PHP can replace the functions of JSP and provide some specific code examples to help readers better understand
