要区分来源就要写代码实现RequestOriginParser接口 ,注意是要实现com.alibaba.csp.sentinel.adapter.servlet.callback.RequestOriginParser 接口,别搞错接口了。
MyRequestOriginParser.java
java
package com.codex.terry.sentinel.origin;
import com.alibaba.csp.sentinel.adapter.servlet.callback.RequestOriginParser;
import org.apache.commons.lang3.StringUtils;
import org.springframework.stereotype.Component;
import javax.servlet.http.HttpServletRequest;
/**
* 文件名称: MyRequestOriginParser.java
* 编写人: yh.zeng
* 编写时间: 2024/6/28 19:14
* 文件描述: 实现区分来源
*/
@Component
public class MyRequestOriginParser implements RequestOriginParser
{
@Override
public String parseOrigin(HttpServletRequest request) {
// 从请求参数中获取名为 origin 的参数并返回
// 如果获取不到origin参数,那么就抛异常
String origin = request.getParameter("origin");
if (StringUtils.isBlank(origin)) {
throw new IllegalArgumentException("origin must be specified");
}
return origin;
}
}
添加FilterRegistrationBean,里面添加WebCallbackManager.setRequestOriginParser(new MyRequestOriginParser());代码,完整代码如下:
FilterContextConfig.java
java
package com.codex.terry.configuration;
import com.alibaba.csp.sentinel.adapter.servlet.CommonFilter;
import com.alibaba.csp.sentinel.adapter.servlet.callback.WebCallbackManager;
import com.codex.terry.sentinel.origin.MyRequestOriginParser;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class FilterContextConfig {
/**
* @NOTE 在spring-cloud-alibaba v2.1.1.RELEASE及前,sentinel1.7.0及后,关闭URL PATH聚合需要通过该方式,spring-cloud-alibaba v2.1.1.RELEASE后,可以通过配置关闭:spring.cloud.sentinel.web-context-unify=false
* 手动注入Sentinel的过滤器,关闭Sentinel注入CommonFilter实例,修改配置文件中的 spring.cloud.sentinel.filter.enabled=false
* 入口资源聚合问题:https://github.com/alibaba/Sentinel/issues/1024 或 https://github.com/alibaba/Sentinel/issues/1213
* 入口资源聚合问题解决:https://github.com/alibaba/Sentinel/pull/1111
*/
@Bean
public 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);
//解决授权规则不生效的问题
//com.alibaba.csp.sentinel.adapter.servlet.callback.RequestOriginParser
WebCallbackManager.setRequestOriginParser(new MyRequestOriginParser());
return registration;
}
}
URL不传origin参数,试试是否报错,如下:

加入origin,正常了,如下:
本案例配置的origin是say,表示来源是say,所以配置规则来源要填say,如下:
