Sping boot添加拦截器

1.添加 拦截器MyInterceptor

public class MyInterceptor implements HandlerInterceptor { private static final Logger log = LoggerFactory.getLogger(MyInterceptor.class); @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) { log.debug("preHandle method is running"); return true; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) { log.debug("postHandle method is running"); } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) { log.debug("afterCompletion method is running"); } }

2.配置拦截器

@Configuration public class MvcConfig implements WebMvcConfigurer { @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new MyInterceptor()).addPathPatterns("/**"); } }
