Servlet Filter doesn't seem to work in Dropwizard

Question

I have written a filter called RequestFilter (implements Filter interface) to get HTTP headers of each request. And I added this filter using the following code in Dropwizard run function.

environment.servlets().addFilter("RequestFilter", new RequestFilter());

doFilter doesn't get called on sending a request.

Any hints on why it is not working?

通过在dropwizard运行函数中添加以下内容解决了此问题。

environment.servlets().addFilter("RequestFilter", new RequestFilter()).addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), true, "<resource_path>/*");
