Spring Boot中使用AOP统一处理web层异常的方法

 private ModelAndView resolve(String viewName, Map<String, Object> model) { String errorViewName = "error/" + viewName; TemplateAvailabilityProvider provider = this.templateAvailabilityProviders  .getProvider(errorViewName, this.applicationContext); if (provider != null) {  return new ModelAndView(errorViewName, model); } return resolveResource(errorViewName, model); }
