在網(wǎng)上找了好多，基本上都一個(gè)樣，按照一步一步來，都是無效，下面是我的配置： Config: import com.example.demo.interceptor.OneInterceptor;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurer; @Configurationpublic class InterceptorConfig implements WebMvcConfigurer { @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new OneInterceptor()).addPathPatterns("/**"); } } OneInterceptor: import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.stereotype.Component;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView; import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse; @Componentpublic class OneInterceptor implements HandlerInterceptor { private Logger logger = LoggerFactory.getLogger(OneInterceptor.class); @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object object) throws Exception { logger.debug("攔截。。。"); return false; } @Override public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) { System.err.println("post"); } @Override public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) { System.err.println("after"); } } 無論訪問什么路徑都不會(huì)走攔截器，不知道哪里配置錯(cuò)了，求大神解答！
