+# Configure rule
+
+Write then dynamic configuration to the registry center,This feature is
usually done by the monitoring center or the center's page.
+
+```java
+RegistryFactory registryFactory =
ExtensionLoader.getExtensionLoader(RegistryFactory.class).getAdaptiveExtension();
+Registry registry =
registryFactory.getRegistry(URL.valueOf("zookeeper://10.20.153.10:2181"));
+registry.register(URL.valueOf("override://0.0.0.0/com.foo.BarService?category=configurators&dynamic=false&application=foo&timeout=1000"));
+```
+
+In the config override url：
+* `override://` Indicates that the data is overwritten,support `override` and
`absent`，can extends，**Required**.
+* `0.0.0.0` Indicates that the configurations is valid for all IP addresses，If
only want to overwritten specified ip data,you can replace that specified ip
address.**Required**.
+* `com.foo.BarService` Indicates that is valid for specified
service,**Required**.
+* `category=configurators` Indicates that the data is dynamic
configuration,**Required**。
+* `dynamic=false` Indicates that the data is persistent,When the registered
party withdraws,the data is still stored in the registry **Required**。
+* `enabled=true` override strategy is enable,can absent,if absent,then enable.
+* `application=foo` Indicates that is valid for specified application,can
absent,if absent,then valid for all application.
+* `timeout=1000` Indicates that the value of the `timeout` parameter that
satisfies the above conditions is overwritten by 1000,if want to override
another parameters, add directly to the `override` URL parameter.
+
+Example：
+
+1. Disable service provider.(Usually used to temporarily kick off a provider
machine, similar to the prohibition of consumer access, please use the routing
rules)
+
+ ```
+
override://10.20.153.10/com.foo.BarService?category=configurators&dynamic=false&disbaled=true
+ ```
+
+2. Adjustment weight:(Usually used to capacity assessment,default is 100)
+
+ ```
+
override://10.20.153.10/com.foo.BarService?category=configurators&dynamic=false&weight=200
+ ```
+
+3. Adjustment load balance strategy.(default random)
+
+ ```
+
override://10.20.153.10/com.foo.BarService?category=configurators&dynamic=false&loadbalance=leastactive
+ ```
+
+4. Service downgrade:(Usually used to temporarily mask an error of
non-critical services)
+
+ ```
+
override://0.0.0.0/com.foo.BarService?category=configurators&dynamic=false&application=foo&mock=force:return+null
+ ```
+
+**NOTE**: `2.2.0+` version supported.
