小编Kis*_*ore的帖子

我已经搜索并看到了有关此问题的几个帖子，但没有找到答案如何可能。

我想要做的是在过滤器链之后添加标头，

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletResponse httpResp = (HttpServletResponse) response;

try {
HttpServletResponseWrapper bufferedResponse = new     HttpServletResponseWrapper (httpResp); 

chain.doFilter(request, bufferedResponse);

} finally {   
// header added at this line is not actually being added.        
bufferedResponse.setHeader("ADD A HEADER: ", "HEADER");
}                                     
}

多个帖子都在谈论使用 HttpServletResponseWrapper 是可能的，但它对我不起作用，任何人都可以帮助我。
