从接口复制的说明: RegistryService

Register data, such as : provider service, consumer address, route rule, override rule and other data.

Registering is required to support the contract:
1. When the URL sets the check=false parameter. When the registration fails, the exception is not thrown and retried in the background. Otherwise, the exception will be thrown.
2. When URL sets the dynamic=false parameter, it needs to be stored persistently, otherwise, it should be deleted automatically when the registrant has an abnormal exit.
3. When the URL sets category=routers, it means classified storage, the default category is providers, and the data can be notified by the classified section.
4. When the registry is restarted, network jitter, data can not be lost, including automatically deleting data from the broken line.
5. Allow URLs which have the same URL but different parameters to coexist,they can't cover each other.

指定者:

register 在接口中 RegistryService

参数:

url - Registration information , is not allowed to be empty, e.g: dubbo://10.20.153.10/org.apache.dubbo.foo.BarService?version=1.0.0&application=kylin

unregister

default void unregister(URL url)

已过时。

从接口复制的说明: RegistryService

Unregister

Unregistering is required to support the contract:
1. If it is the persistent stored data of dynamic=false, the registration data can not be found, then the IllegalStateException is thrown, otherwise it is ignored.
2. Unregister according to the full url match.

指定者:

unregister 在接口中 RegistryService

参数:

url - Registration information , is not allowed to be empty, e.g: dubbo://10.20.153.10/org.apache.dubbo.foo.BarService?version=1.0.0&application=kylin

subscribe

default void subscribe(URL url,
                       NotifyListener listener)

已过时。

从接口复制的说明: RegistryService

Subscribe to eligible registered data and automatically push when the registered data is changed.

Subscribing need to support contracts:
1. When the URL sets the check=false parameter. When the registration fails, the exception is not thrown and retried in the background.
2. When URL sets category=routers, it only notifies the specified classification data. Multiple classifications are separated by commas, and allows asterisk to match, which indicates that all categorical data are subscribed.
3. Allow interface, group, version, and classifier as a conditional query, e.g.: interface=org.apache.dubbo.foo.BarService&version=1.0.0
4. And the query conditions allow the asterisk to be matched, subscribe to all versions of all the packets of all interfaces, e.g. :interface=*&group=*&version=*&classifier=*
5. When the registry is restarted and network jitter, it is necessary to automatically restore the subscription request.
6. Allow URLs which have the same URL but different parameters to coexist,they can't cover each other.
7. The subscription process must be blocked, when the first notice is finished and then returned.

指定者:

subscribe 在接口中 RegistryService

参数:

url - Subscription condition, not allowed to be empty, e.g. consumer://10.20.153.10/org.apache.dubbo.foo.BarService?version=1.0.0&application=kylin

listener - A listener of the change event, not allowed to be empty

unsubscribe

default void unsubscribe(URL url,
                         NotifyListener listener)

已过时。

从接口复制的说明: RegistryService

Unsubscribe

Unsubscribing is required to support the contract:
1. If don't subscribe, ignore it directly.
2. Unsubscribe by full URL match.

指定者:

unsubscribe 在接口中 RegistryService

参数:

url - Subscription condition, not allowed to be empty, e.g. consumer://10.20.153.10/org.apache.dubbo.foo.BarService?version=1.0.0&application=kylin

listener - A listener of the change event, not allowed to be empty

lookup

default List<URL> lookup(URL url)

已过时。

从接口复制的说明: RegistryService

Query the registered data that matches the conditions. Corresponding to the push mode of the subscription, this is the pull mode and returns only one result.

指定者:

lookup 在接口中 RegistryService

参数:

url - Query condition, is not allowed to be empty, e.g. consumer://10.20.153.10/org.apache.dubbo.foo.BarService?version=1.0.0&application=kylin

返回:

The registered information list, which may be empty, the meaning is the same as the parameters of org.apache.dubbo.registry.NotifyListener#notify(List).
