问题 We are using a servlet filter to inject a string into the response before returning it. We are using an implementation of HttpServletResponseWrapper to do this.

问题 I'm trying to adjust my application configuration in order to setup ETag support. I have just checked this SO question, so let me say where my code is different from it: I don't use any xml configuration file whatsoever.

问题 In tomcat for a certain url, I want to skip all the filters and execute a servlet and I thought placing the servlet before the filter will to as I expected but still the filters behind the servlet mappings are executing. Am I doing anything wrong? For instance, this is my web.xml <servlet> <servlet-name>APIRedirection</servlet-name> <servlet-class>com.test.APIRedirection</servlet-class> </servlet> <servlet-mapping> <servlet-name>APIRedirection</servlet-name> <url-pattern>/abc/*</url-pattern>

问题 I'm working on a java project based on spring-MVC. I have users - students in this issue - which I'd like to check on each page they navigate, if they are logged it.
