This article mainly introduces the composition of the JSP system, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

The JSP system mainly consists of four parts:

1) Database connection part: the JSP system supports several commonly used databases, including Oracle, Sybase, MSSQLServer, MySQL and DB2. According to the database type selected by the user and the database name, user name and password provided by the user, JDBC is used to connect to the database.

2) system basic table generation: after connecting with the database, two system basic tables TC-Tables and TC-Columns,TC-Tables tables are generated according to the user name connected to the database, including the English names, Chinese names and some attributes of all the tables belonging to the user in the database, such as whether they can be modified, queried, etc. The TC-Columns table contains the English and Chinese names and other attributes of all the columns of all tables belonging to the user in the database. Such as whether it can be displayed, whether it can be queried, and so on. These two system basic tables provide the basic information of the database used by the user during the development of the whole system.

3) template selection and web page generation: this part is the core part of the JSP system. It contains two sub-modules.

① template selection part: the system provides users with a template selection interface, which allows users to select the template to be used from the template library according to their needs.

② template processing part: according to the template selected by the user, the system calls the specified template processing module to process the template. When the processor encounters the tag in the template, it provides an interactive interface for the user to enter parameters for the specified tag, and the system verifies the validity of the tag entered by the user. * the JSP page is generated by the system.

4) Web page preview and modification: after the web page is generated, the system provides users with a web page preview window and code view modification window. Through this preview window, the user can preview the effect of the generated JSP page. If the user is not satisfied with the effect of the static aspect of the page, the user can modify the HTML code in the code through the code view modification window. If the user has further requirements for the static effect of the page, the system also provides an interface for the user to call the DreamWeaver editor, which can be used to further modify and improve the static effect of the generated JSP page.

Thank you for reading this article carefully. I hope the article "how to make up a JSP system" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
