Editor to share with you what the meaning and usage of JSP tags, I believe that most people still do not understand, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to understand it!

< jsp:include>

The tag indicates that it contains a static or dynamic file.

< jsp:forward>

The tag indicates to redirect a static html/jsp file, or a program segment.

Syntax:

< jsp:forward page="path"} />

Or

< jsp:forward page="path"} >

< jsp:param name="paramName" value="paramValue" />

……

< /jsp:forward>

< jsp:useBean>

The tag indicates that it is used to create an BEAN instance in the JSP page and specify its name and scope.

Syntax:

< jsp:useBean id="name" scope="page | request | session | application" typeSpec />

There are several possible scenarios for typeSpec:

Class= "className" | class= "className" type= "typeName" | beanName= "beanName" type= "typeName" | type= "typeName" |

Note:

In the use of this JSP tag, you must use class or type, not both class and beanName. BeanName represents the name of Bean in the form of "a.b.c".

< jsp:getProperty>

The tag means to get the value of the property of BEAN, convert it to a string, and then insert it into the output

< jsp:setProperty>

The tag represents the value used to set the attribute in the Bean.

< jsp:setProperty name="login" property="username" value="Paopao">

< /jsp:setProperty>

< jsp:setProperty name="login" property="password" value="Love">

< /jsp:setProperty>

< jsp:plugin>

The tag indicates that an applet or Bean is executed and, if possible, a Java plug-in is downloaded to execute it.
