Spring: 利用拦截器实现请求通用逻辑处理

@Component
public class HandlerInterfaceInterceptor implements AsyncHandlerInterceptor {


  @Override
  public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
      throws Exception {


          // 处理代码.记录日志,鉴权,等等.
          // 此处可以通过request传递参数.

          return true;
      }
}


@Configuration
public class ResourcesConfig implements WebMvcConfigurer {

  @Autowired private HandlerInterfaceInterceptor handlerInterfaceInterceptor;

  /** 自定义拦截规则 */
  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    registry
        .addInterceptor(handlerInterfaceInterceptor)
        // 拦截指定请求地址.
        .addPathPatterns("/external-api/v1/**");
  }
}
