问题 I want to server a JSP page that is stored in a database as a blob. So if a request comes in at the url http://mydomain.com/app/list.jsp I know to go to the DB to retrieve the resource list.jsp. I am using spring and tiles, so have adispatcher servlet and controllers set up and working in traditional sense. Would this be similar in principle to the resource servlet that spring web has to serve javascript files and messages from within jar? Note that the JSPs would not just be static HTML, I

问题 How can I get _csrf object (?!) in spring controller? I've configured Spring Security and can get ${_csrf} request attribute in jsp files.

问题 I am trying to pass an argument to my @RESTController Spring Boot class. In the @POSTMapping method I want to use a method of a self defined Java class for processing the received body and returning a response. The Spring application is launched in Application.java. The Controller-Object seems to get created implicitly. I already tried adding a constructor to my RESTController class. But I couldn't find a way to call that constructor with an argument. // Application.java public static void

问题 Suppose I have a certain operation that should be available to every process running in Spring MVC. Say string normalization-- i need to run a method that normalizes the string fields before doing anything else on that form/data.
