Retrieving Session ID with Spring Security
提问by abyx
For logging purposes, I'd like to create a logger that automatically adds the current session's ID to logged lines.
For logged in users this isn't a problem:
出于记录目的，我想创建一个记录器，它会自动将当前会话的 ID 添加到记录的行中。
对于登录用户，这不是问题：
((WebAuthenticationDetails) SecurityContextHolder.getContext().getAuthentication().getDetails())
.getSessionId()
The problem is, before the user has logged in getAuthentication()returns null. Is there another way for getting the session ID without having a reference to the current response or anything of that sort?
问题是，在用户登录之前getAuthentication()返回null。是否有另一种方法可以在不引用当前响应或任何类似内容的情况下获取会话 ID？

You may use
您可以使用
RequestContextHolder.currentRequestAttributes().getSessionId();
This relies on Spring's RequestContextHolder, so it should be used with Spring MVC's DispatcherServletor you should have a RequestContextListenerdeclared. Also session will be created if not exists.
这依赖于 Spring 的RequestContextHolder，所以它应该与 Spring MVC 一起使用，DispatcherServlet或者你应该有一个RequestContextListener声明。如果不存在，也会创建会话。
