在JSP文件中导入类 [英] Importing a class in a JSP file
问题描述
我写了一些代码作为Java Servlet，现在我试图将它转换为JSP。我在一个单独的文件中写了一个类，我正在使用，我不知道如何获得JSP文件来识别类。我想它与进口有关。我给这个类一个包（ package mypackagename; ）名称，我尝试使用<％@ page import =mypackagename％& code>但我得到一个错误：
I wrote some code as a Java Servlet and now I am trying to convert it to a JSP. I wrote a class in a separate file which I was using, and I can't figure out how to get the JSP file to recognize the class. I guess it has something to do with importing. I gave the class a package (package mypackagename;) name and I tried using <%@ page import="mypackagename"%> but I get an error:
导入mypackagename无法解决
The import "mypackagename" cannot be resolved
推荐答案
只需以与在真正的Java类中一样的方式导入它。也就是说 import mypackagename.MyClassName 或 import mypackagename。，因此不
Just import it the same way as you do in a real Java class. I.e. import mypackagename.MyClassName or import mypackagename.* and thus not import mypackagename with only the package name.
<%@ page import="mypackagename.MyClassName" %>
也就是说，在JSP文件中。
