Taglib instruction

Defix a label library and its custom label.

.

description

<% @ Taglib%> The directive declares that this JSP file uses a custom label, and references the label library, also specifies the prefix of their label.

The custom label here contains tags and elements. Because the JSP file can be converted to XML, it is important to understand the connection between the label and elements. The label is just a mark that is raised in a sense, which is part of the JSP element. The JSP element is part of the JSP syntax, and the start tag and end tag are the same as XML. Elements can also contain other texts, tags, and elements. For example, a JSP: Plugin element has Start tags and End tags, like the and elements.

You must use <% @ taglib%> instruction before using the custom label, and you can use multiple times in a page, but the prefix can only use it once
