SpringBoot 的 Filter

废话少说，上代码

import javax.servlet.*;import javax.servlet.annotation.WebFilter;import java.io.IOException;/** * @author Li */@WebFilter(filterName = "filter", urlPatterns = "/*")public class Myfilter implements Filter {    @Override    public void init(FilterConfig filterConfig) throws ServletException {    }    @Override    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {//        System.out.println("前");        chain.doFilter(request, response);//        System.out.println("后");    }    @Override    public void destroy() {    }}

上面这部分是一个注解的webfilter

@Configurationpublic class springConfig{    @Bean    public Myfilter myfilter() {        return new Myfilter();    }}
