OncePerRequestFilter.doFilter方法中通过request.getAttribute判断当前过滤器是否已执行 若未执行过,则调用doFilterInternal方法,交由其子类实现 */ @Override protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOE...
与zuul不同的是,filter除了分为“pre”和“post”两种方式的filter外,在Spring Cloud Gateway中,filter从作用范围可分为另外两种,一种是针对于单个路由的gateway filter,它在配置文件中的写法同predict类似;另外一种是针对于所有路由的global gateway filer。现在从作用范围划分的维度来讲解这两种filter。 gateway filter...

Filter的执行顺序 先看SCG文档3. How It Works中的这张图: 这张图大概告诉你了SCG的调用过程,可以看到经过了一堆Filters,但是并没有告诉你Filter的执行顺序。然后在SCG的6.1 Combined Global Filter and GatewayFilter Ordering提到了: As Spring Cloud Gateway distinguishes between "pre" and "post" phases for...
