WebMvcConfigurerAdapter使用时提示已过时，看网上建议使用WebMvcConfigurationSupport，但使用这个会是springboot的自动配置有问题：@ConditionalOnMissingBean(WebMvcConfigurationSupport.class)。所以建议实现 implements WebMvcConfigurer。
代码附上:
拦截器：
package com.abc.interceptor; /* * author : ajing * date : 2018/4/4 15:53 * */ import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.handler.HandlerInterceptorAdapter; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class WebIntercrptor extends HandlerInterceptorAdapter{ @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { long startTime=System.currentTimeMillis(); request.setAttribute("startTime",startTime); System.out.println("前拦截器处理完毕"); return true; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception { long startTime = (long) request.getAttribute("startTime"); long endTime=System.currentTimeMillis(); System.out.println("后拦截器处理完毕，本次处理时间为："+(endTime-startTime)); request.setAttribute("handleTime",endTime-startTime); } }拦截器配置：
package com.abc.interceptor; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.*; import org.springframework.web.servlet.view.InternalResourceViewResolver; import org.springframework.web.servlet.view.JstlView; /* * author : ajing * date : 2018/4/9 14:55 * */ @Configuration public class webInterceptorAdapter implements WebMvcConfigurer { @Bean public WebIntercrptor webIntercrptor(){ return new WebIntercrptor(); } @Override public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/error").setViewName("404.html"); } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(webIntercrptor()).addPathPatterns("/**"); } //注入视图处理器bean @Bean public InternalResourceViewResolver viewResolver(){ InternalResourceViewResolver resourceViewResolver=new InternalResourceViewResolver(); resourceViewResolver.setPrefix("/templates/"); resourceViewResolver.setSuffix(".html"); resourceViewResolver.setViewClass(JstlView.class); return resourceViewResolver; } //添加文件是暴露路径和文件的实际访问路径 @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler("/view").addResourceLocations("/"); } }controller:
@RequestMapping(value = "getPlanNoteVersion", method = {RequestMethod.GET,RequestMethod.POST}, produces = "application/json;charset=utf-8") public PlanNote getPlanNoteVersion(){ PlanNote planNote=new PlanNote(); // planNote.setVersion(area); planNote.setOwner(propertiesBean.getOwner()); logger.info("【获取笔记版本和开发者信息】"); return planNote; }启动类：
package com.abc; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication //开启Spring Boot的自动配置 public class SpringbootApplication { public static void main(String[] args) { SpringApplication.run(SpringbootApplication.class, args); } }
