推荐答案

如果您说的是使用include方法"，则可能是想通过插入<%@ include ...％> [

If you are saying "using the include method", you are probably saying that you want to include on jsp page in another by inserting a <%@ include ... %>[^] page directive. This is analogous to including header files in C or C++. The source code that is linked in the include directive is inserted at the same place where the tag previously was. Look at it as a substitution.
That having been said you''ll understand that in the include scenario there is no need to pass anything as all files, the parent jsp plus all included children jsp pages, become on big document. So all you have to be aware of are the usual Java scoping rules regarding variables and their visibility.
