### 1、定义一个拦截器类 ###

import com.alibaba.fastjson.JSON;
    import org.apache.commons.logging.Log;
    import org.apache.commons.logging.LogFactory;
    import org.springframework.stereotype.Service;
    import org.springframework.web.servlet.HandlerInterceptor;
    import org.springframework.web.servlet.ModelAndView;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.util.HashMap;
    import java.util.Map;
    
    
    @Service
    public class UrlLogInterceptor implements HandlerInterceptor {
        private static final Log log = LogFactory.getLog(UrlLogInterceptor.class);
        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
    
                Map<String, String[]> params=new HashMap<>(request.getParameterMap());
                params.remove("password");
                try {
                    String ip=request.getHeader("X-Real-IP");
                    if(ip==null){
                        ip=request.getRemoteAddr();
                    }
                    log.info(request.getRequestURI()+" "+request.getMethod()+" user:"+request.getSession().getAttribute("user")+" "+request.getAttribute("user")+" "
                            +request.getHeader("X-Forwarded-For")+" "+ip+" "+JSON.toJSONString(params));
                }catch (Exception e){
                    log.info(request.getRequestURI()+" "+request.getMethod()+" user:"+"<error>"+" "
                            +request.getHeader("X-Forwarded-For")+" "+request.getRemoteAddr()+" "+JSON.toJSONString(params));
                }
                if(request.getMethod().equals("OPTIONS")){
                    return false;
                }
            return true;
        }
    
        @Override
        public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
                               ModelAndView modelAndView) throws Exception {
        }
    
        @Override
        public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
        }
    }

### 2、添加拦截器类的配置 ###

package com.edu.platform.config;
    
    import com.edu.platform.interceptor.LoginInterceptor;
    import com.edu.platform.interceptor.UrlLogInterceptor;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.servlet.HandlerInterceptor;
    import org.springframework.web.servlet.ModelAndView;
    import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    @SuppressWarnings("SpringJavaAutowiringInspection")
    @Configuration
    public class InterceptorConfig extends WebMvcConfigurerAdapter implements HandlerInterceptor {
        @Autowired
        private LoginInterceptor loginInterceptor;
    
        @Autowired
        private UrlLogInterceptor urlLogInterceptor;
    
        @Override
        public void addInterceptors(InterceptorRegistry registry) {
            registry.addInterceptor(loginInterceptor)
            		.addPathPatterns("/**")
            		.excludePathPatterns("/login",
                            //"/logout",
                            "/downloadguide",
                            "/loginvalidate",
                            "/webapp/plogin",
                            "/webapp/code",
                            "/css",
                            "/fonts",
                            "/img",
                            "/js",
                            "/plugins");
            registry.addInterceptor(urlLogInterceptor);
            super.addInterceptors(registry);
        }
    
        @Override
        public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
            return false;
        }
    
        @Override
        public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
        }
    
        @Override
        public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
        }
    }
