适用方式
- 增加interceptor，implements HandlerInterceptor，实例如下
@Slf4j
public class AccessInterceptor implements HandlerInterceptor {@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {return true;}@Overridepublic void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {log.info("accessInterceptor:权限查询。。。。。。。。");}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {}
}
- 注册到WebMvcConfigurationSupport或者WebMvcConfigurer的继承类中
@Configuration
public class AxLogInterWebConfig extends WebMvcConfigurationSupport {@BeanLogInterceptor logInterceptor() {return new LogInterceptor();}@Overridepublic void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(logInterceptor());}
}
失效分析
如果失效了的话，那么可能出现如下原因
- 没有扫描到包
- path配置错误
上面是常规原因，最有可能的原因是：
3. WebMvcConfigurationSupport优先级大于WebMvcConfigurer，如果继承的话，那么优先继承WebMvcConfigurationSupport
4. 注意：WebMvcConfigurationSupport只能生效一个，如果有多个，那么也只能生效一个。
