+# Sentinel Spring Cloud Zuul Adapter
+
+Zuul does not provide rateLimit function, If use default `SentinelRibbonFilter` route filter. it wrapped by Hystrix Command. so only provide Service level 
+circuit protect. 
+
+Sentinel can provide `ServiceId` level and `API Path` level flow control for spring cloud zuul gateway service. 
+
+*Note*: this project is for zuul 1.
+
+## How to use
+
+1. Add maven dependency
+
+```xml
+<dependency>
+    <groupId>com.alibaba.cloud</groupId>
+    <artifactId>spring-cloud-alibaba-sentinel-gateway</artifactId>
+    <version>x.y.z</version>
+</dependency>
+
+```
+
+2. Set application.property
+
+```
+// default value is false
+spring.cloud.sentinel.zuul.enabled=true
+```
+
+## How it works
+
+As Zuul run as per thread per connection block model, we add filters around `route Filter` to trace sentinel statistics.   
+
+- `SentinelPreFilter`: Get an entry of resource,the first order is **ServiceId**, then **API Path**. 
+- `SentinelPostFilter`: When success response,exit entry.
+- `SentinelErrorFilter`:  When get an `Exception`, trace the exception and exit context. 
+
+
+the order of Filter can be changed by configuration:
+
+```
+spring.cloud.sentinel.zuul.order.post=0
+spring.cloud.sentinel.zuul.order.pre=10000
+spring.cloud.sentinel.zuul.order.error=-1
+```
+
+
+Filters create structure like:
+
+
+```bash
+
+EntranceNode: machine-root(t:3 pq:0 bq:0 tq:0 rt:0 prq:0 1mp:0 1mb:0 1mt:0)
+-EntranceNode: coke(t:2 pq:0 bq:0 tq:0 rt:0 prq:0 1mp:0 1mb:0 1mt:0)
+--coke(t:2 pq:0 bq:0 tq:0 rt:0 prq:0 1mp:0 1mb:0 1mt:0)
+---/coke/uri(t:0 pq:0 bq:0 tq:0 rt:0 prq:0 1mp:0 1mb:0 1mt:0)
+-EntranceNode: sentinel_default_context(t:0 pq:0 bq:0 tq:0 rt:0 prq:0 1mp:0 1mb:0 1mt:0)
+-EntranceNode: book(t:1 pq:0 bq:0 tq:0 rt:0 prq:0 1mp:0 1mb:0 1mt:0)
+--book(t:1 pq:0 bq:0 tq:0 rt:0 prq:0 1mp:0 1mb:0 1mt:0)
+---/book/uri(t:0 pq:0 bq:0 tq:0 rt:0 prq:0 1mp:0 1mb:0 1mt:0)
+
+```
+
+`book` and `coke` are serviceId. 
+
+`---/book/uri` is api path, the real uri is `/uri`. 
+
+
+## Integration with Sentinel DashBord
+
+Start [Sentinel DashBord](https://github.com/alibaba/Sentinel/wiki/%E6%8E%A7%E5%88%B6%E5%8F%B0).
+
+## Rule config with dataSource
+
+Sentinel has full rule config features. see [Dynamic-Rule-Configuration](https://github.com/alibaba/Sentinel/wiki/Dynamic-Rule-Configuration)
+
+
+## Custom Fallbacks
+
+Implements `SentinelFallbackProvider` to define your own Fallback Provider when Sentinel Block Exception throwing for different rout. the default 
+Fallback Provider is `DefaultBlockFallbackProvider`. 
+
+By default Fallback route is `ServiveId + URI PATH`, example `/book/coke`, first `book` is serviceId, `/uri` is URI PATH, so both  
+can be needed.
+
+Here is an example:
+
+```java
+
+// custom provider 
+public class MyCokeServiceBlockFallbackProvider implements SentinelFallbackProvider {
+
+    private Logger logger = LoggerFactory.getLogger(DefaultBlockFallbackProvider.class);
+    
+    // you can define root as service level 
+    @Override
+    public String getRoute() {
+        return "/coke/uri";
+    }
+
+    @Override
+    public ClientHttpResponse fallbackResponse(String route, Throwable cause) {
+        if (cause instanceof BlockException) {
+            logger.info("get in fallback block exception:{}", cause);
+            return response(HttpStatus.TOO_MANY_REQUESTS, route);
+        } else {
+            return response(HttpStatus.INTERNAL_SERVER_ERROR, route);
+        }
+    }
+ }
+
+```
+
+## Custom Request Origin Parser
+By default this adapter use `DefaultRequestOriginParser` to parse sentinel origin.
+
+```java
+
+public class CustomRequestOriginParser implements RequestOriginParser {
+    @Override
+    public String parseOrigin(HttpServletRequest request) {
+        // do custom logic.
+        return "";
+    }
+}
+
+```
+
+## Custom UrlCleaner
+By default this adapter use `DefaultUrlCleaner` to define uri resource. 
+
+```java
+public class CustomUrlCleaner implements UrlCleaner {
+
+    @Override
+    public String clean(String originUrl) {
+        // do custom logic.
+        return originUrl;
+    }
+}
+```
