包括来自Servlet的私有JSP [英] Include a private JSP from a Servlet

问题描述

我让Servlet响应所有的"/" URL模式.在内部，我有时需要呈现html，因此我想.include一个JSP页面，但我希望该.jsp在外部无法访问.另外，如何将模型对象传递给它.

I have my Servlet responding on the everything "/" url-pattern. Inside I need to sometimes render html, so I'd like to .include a JSP page, but I'd like that .jsp to be inaccessible externally. Also, how can I pass a model object into it.

推荐答案

我想.include一个JSP页面，但我希望该.jsp在外部无法访问.

将其放在/WEB-INF文件夹中.客户端无法访问它，但是RequestDispatcher可以访问它.

Put it in /WEB-INF folder. The client cannot access it, but the RequestDispatcher can access it.

request.getRequestDispatcher("/WEB-INF/page.jsp").forward(request, response);

此外，如何将模型对象传递到其中.

将其设置为请求属性.

request.setAttribute("bean", bean); // It'll be available as ${bean} in JSP.

也就是说，请注意，在/上映射servlet会接管servlet容器内置的DefaultServlet的工作，以提供静态内容.您必须自己处理所有静态文件，例如JS/CSS/images.考虑为JSP视图选择更具体的url-pattern，例如/pages/*或*.do.最终在Filter >这个答案.

That said, be aware that mapping a servlet on / takes over the job of servletcontainer's builtin DefaultServlet for serving static content. You'll have to handle all static files like JS/CSS/images yourself. Consider choosing a more specific url-pattern like /pages/* or *.do for JSP views. Bring eventually a Filter in front as outlined in this answer.
