SPRING-MVC non-controller layer get HttpServletRequest

Source: Internet
Author: User

Documenting the operations log in a project is a common requirement.

Sometimes we log on the service or DAO layer, we need to save the access IP, login user name and so on. It would be cumbersome to pass the HttpServletRequest object through the controller layer. HttpSession can be obtained indirectly through HttpServletRequest.

In the Web. XML configuration

<listener> <listener-class>org.springframework.web.context.request.requestcontextlistener</ Listener-class> </listener>


The code to get HttpServletRequest in service or DAO is as follows

HttpServletRequest request = ((servletrequestattributes) requestcontextholder. Getrequestattributes ()). Getrequest ();

For convenience, you can avoid duplication by extracting the above code into a tool method.
