单击超链接调用servlet [英] Call a servlet on click of hyperlink

问题描述

有没有办法在不使用JavaScript的情况下点击超链接调用Java Servlet？

Is there a way to call a Java Servlet on click of hyperlink without using JavaScript?

推荐答案

使超链接有一个您在 web.xml 文件中定义了servlet映射的URL。

Make the hyperlink have a URL that you have a servlet mapping defined for in the web.xml file.

servlet-mapping 元素定义了servlet和URL模式之间的映射。下面的示例将名为 myservlet 的servlet映射到以 / foo 开头的任何URL：

The servlet-mapping element defines a mapping between a servlet and a URL pattern. The example below maps the servlet named myservlet to any URL that starts with /foo:

<servlet>
  <servlet-name>myservlet</servlet-name>
  <servlet-class>com.stackoverflow.examples.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>myservlet</servlet-name>
  <url-pattern>/foo/*</url-pattern>
</servlet-mapping>

• 对于此示例，超链接如 < a href =/ foo / test.html>点击我< / a> 将调用servlet。


• For this example, a hyperlink such as <a href="/foo/test.html">Click Me</a> would invoke the servlet.
