最近在做一个springcloudAlibaba项目，做链路流控模式时需要将入口资源关闭聚合，做法如下：
spring-cloud-alibaba v2.1.1.RELEASE及前，sentinel1.7.0及后：
1.pom 中引入：

<dependency><groupId>com.alibaba.csp</groupId><artifactId>sentinel-web-servlet</artifactId><version>1.8.0</version>
</dependency>

2.添加一下配置：

package com.atguigu.springcloud.config;import com.alibaba.csp.sentinel.adapter.servlet.CommonFilter;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
public class FilterContextConfig {@Beanpublic FilterRegistrationBean sentinelFilterRegistration() {FilterRegistrationBean registration = new FilterRegistrationBean();registration.setFilter(new CommonFilter());registration.addUrlPatterns("/*");// 入口资源关闭聚合registration.addInitParameter(CommonFilter.WEB_CONTEXT_UNIFY, "false");registration.setName("sentinelFilter");registration.setOrder(1);return registration;}
}

spring-cloud-alibaba v2.1.1.RELEASE后:

配置文件添加：
spring.cloud.sentinel.web-context-unify=false
