Springboot 打印 接口 耗时时间

三种方式 下面为大家一一对应

• 过滤器的方式
• 拦截器的方式

拦截器的介绍

话不说多 直接上代码

创建拦截器

/**
 * 拦截器：Spring框架特有的，常用于登录校验，权限校验，请求日志打印 /login
 * @author : look-word
 * 2022-06-26 13:55
 **/
@Component
public class LogInterceptor implements HandlerInterceptor {
    private static final Logger LOG = LoggerFactory.getLogger(LogInterceptor.class);

        
    @Override
     public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
         // 打印请求信息
         LOG.info("------------- LogInterceptor 开始 -------------");
         LOG.info("请求地址: {} {}", request.getRequestURL().toString(), request.getMethod());
         LOG.info("远程地址: {}", request.getRemoteAddr());

         long startTime = System.currentTimeMillis();
         request.setAttribute("requestStartTime", startTime);
         return true;
     }

     @Override
     public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
         long startTime = (Long) request.getAttribute("requestStartTime");
         LOG.info("------------- LogInterceptor 结束 耗时：{} ms -------------", System.currentTimeMillis() - startTime);
     }
}

注册拦截器

把我们的拦截器 注册到 拦截器链中

/**
 * @author : look-word
 * 2022-06-26 14:03
 **/
@Configuration
public class SpringMvcConfig implements WebMvcConfigurer {

    @Resource
    private LogInterceptor logInterceptor;
    /**
     * 注册拦截器
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry
                .addInterceptor(logInterceptor)
                .addPathPatterns("/**")// 对那些接口拦截
                .excludePathPatterns("/login");// 对哪些接机口放行
        WebMvcConfigurer.super.addInterceptors(registry);
    }
}
