1.先写拦截器
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import org.slf4j.LoggerFactory;
    import java.io.IOException;
    import javax.servlet.*;
    
    public class SpringBootFilter implements Filter {  
    
    private static final org.slf4j.Logger logger = LoggerFactory.getLogger(SpringBootFilter.class);
    @Override
    public void init(javax.servlet.FilterConfig filterConfig) throws ServletException {
    
    }  
      
        @Override  
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {  
        HttpServletRequest httpRequest = (HttpServletRequest) servletRequest;
             HttpServletResponse httpResponse = (HttpServletResponse) servletResponse;
             String url = httpRequest.getRequestURI().substring(httpRequest.getContextPath().length());
             logger.info(url);
             logger.info("path>>>>"+httpRequest.getRequestURI());
             logger.info("request>>>"+httpRequest);
             logger.info("response>>>"+httpResponse);
             filterChain.doFilter(httpRequest, httpResponse);
        }  
      
        @Override  
        public void destroy() {  
      
        }
    
    }  
    
    
    
    2.配置拦截器
    
    import javax.servlet.Filter;
    import org.springframework.boot.web.servlet.FilterRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    @Configuration
    public class FilterConfig {
    
      /**
         * 配置过滤器
         * @return
         */
        @Bean
        public FilterRegistrationBean someFilterRegistration() {
            FilterRegistrationBean registration = new FilterRegistrationBean();
            registration.setFilter(sessionFilter());
            registration.addUrlPatterns("/*");
            registration.addInitParameter("paramName", "paramValue");
            registration.setName("sessionFilter");
            return registration;
        }
    
        /**
         * 创建一个bean
         * @return
         */
        @Bean(name = "sessionFilter")
        public Filter sessionFilter() {
            return new SpringBootFilter();
        }
    
    }
