1.编写自定义拦截器
我们紧接上一章的工程源码来做
package com.example.firstweb.interceptor;import com.example.firstweb.util.Constants;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Enumeration;Component
public class AccessInterceptor implements HandlerInterceptor {Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object obj) throws Exception {String queryPath request.getContextPath() request.getServletPath();StringBuffer alldatanew StringBuffer();alldata.append(http:// request.getServerName() : request.getServerPort() queryPath);//get请求if (null ! request.getQueryString()) {alldata.append(? request.getQueryString());alldata.append( );}else{alldata.append( );}//POST请求EnumerationString keys request.getParameterNames();if (null ! keys) {while (keys.hasMoreElements()) {String key keys.nextElement();String value request.getParameter(key);alldata.append(key value );}}Constants.LOG_ACCESS_INFO.info(alldata.toString());alldata.setLength(0);return true;}}
2.配置自定义拦截器
package com.example.firstweb.config;import com.example.firstweb.interceptor.AccessInterceptor;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.method.support.HandlerMethodArgumentResolver;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;import javax.annotation.Resource;
import java.util.List;Configuration
public class WebConfig implements WebMvcConfigurer {Resourceprivate AccessInterceptor accessInterceptor;Overridepublic void addInterceptors(InterceptorRegistry registry) {// 自定义拦截器添加拦截路径和排除拦截路径registry.addInterceptor(accessInterceptor).addPathPatterns(/**).excludePathPatterns(/hello); // 排除某些不需要拦截的请求url即带有/hello请求不会被拦截}Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {
// 需要配置1----------- 需要告知系统这是要被当成静态文件的
// 第一个方法设置访问路径前缀第二个方法设置资源路径registry.addResourceHandler(/**).addResourceLocations(classpath:);registry.addResourceHandler(/static/**).addResourceLocations(classpath:/static/);registry.addResourceHandler(/images/**).addResourceLocations(classpath:/images/);registry.addResourceHandler(/js/**).addResourceLocations(classpath:/js/);registry.addResourceHandler(/templates/**).addResourceLocations(classpath:/templates/);}}然后在从welcome的控制器里面增加一个post方法
package com.example.firstweb.controller;import com.example.firstweb.exception.CommException;
import com.example.firstweb.model.po.WelcomePo;
import com.example.firstweb.model.vo.WelcomeVo;
import com.example.firstweb.service.WelcomeService;
import com.example.firstweb.util.Constants;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;import org.apache.log4j.Logger;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.servlet.ModelAndView;Controller
Api(value welcome controller, tags 欢迎界面)
public class Welcome {Autowiredprivate WelcomeService welcomeService;private static final Logger log Logger.getLogger(Welcome.class);GetMapping(/welcomeindex)ApiOperation(欢迎首页的方法1)public ModelAndView welcomeIndex(){ModelAndView view new ModelAndView(welcomeindex);WelcomePo wpo welcomeService.getWelcomInfo();WelcomeVo wvo new WelcomeVo();BeanUtils.copyProperties(wpo, wvo);view.addObject(welcomedata, wvo);//默认控制台输出日志log.info(default log info );//输出访问日志Constants.LOG_ACCESS_INFO.info(welcome index accesss);//输出用户阅读日志Constants.LOG_USER_READ.info(first user access log );return view;}PostMapping(/welcomeindex2)ApiOperation(欢迎首页的方法2)public void welcomeIndex2(ApiParam(定制欢迎词) String test){}
}
启动整个工程代码然后用postman分别GET访问http://localhost:8088/welcomeindex?namesssshokow 用post访问http://localhost:8088/welcomeindex2 然后在日志文件access.log分别找到两条日志 程序的源码可以在这里获得链接: https://pan.baidu.com/s/1v23PyXwB4kvxd79jgLurHw 提取码: mkwc
