关于 spring cloud alibaba 2.2.0 引入 sentinel 找不到 WebCallBackManager

spring cloud alibaba 2.2.0

• 需要引入sentinel-spring-webmvc-dapter ， 基于 Spring 的 Interceptor 拦截资源,而不再是 CommonFilter。
• 不兼容UrlBlockHandler
• 使用BlockExceptionHandler

            <groupId>com.alibaba.csp</groupId>
            <artifactId>sentinel-spring-webmvc-adapter</artifactId>
        </dependency>

• `
  @Component
  public class SeckillSentinelConfig implements BlockExceptionHandler {

  @Override
  public void handle(HttpServletRequest request, HttpServletResponse response, BlockException e) throws Exception {
  R r = R.error(BizCodeEnum.TO_MANY_REQUEST.getCode(), BizCodeEnum.TO_MANY_REQUEST.getMsg());
  response.setContentType(“application/json;charset=utf-8”);
  response.getWriter().write(JSON.toJSONString®);
  }
  }`
