类 ApolloDynamicConfiguration

java.lang.Object

org.apache.dubbo.configcenter.support.apollo.ApolloDynamicConfiguration

所有已实现的接口:

AutoCloseable, DynamicConfiguration, Configuration

public class ApolloDynamicConfiguration
extends Object
implements DynamicConfiguration

Apollo implementation, https://github.com/ctripcorp/apollo Apollo will be used for management of both governance rules and .properties files, by default, these two different kinds of data share the same namespace 'dubbo'. To gain better performance, we recommend separate them by giving namespace and group different values, for example: , 'dubbo=governance' is for governance rules while 'group=dubbo' is for properties files. Please see http://dubbo.apache.org/zh-cn/docs/user/configuration/config-center.html for details.

方法概要

限定符和类型	方法和说明
void	addListener(String key, String group, ConfigurationListener listener) Since all governance rules will lay under dubbo group, this method now always uses the default dubboConfig and ignores the group parameter.
String	getConfig(String key, String group, long timeout) Get the configuration mapped to the given key and the given group.
String	getInternalProperty(String key) This method will be used by Configuration to get valid value at runtime.
String	getProperties(String key, String group, long timeout) Recommend specify namespace and group when using Apollo.
void	removeListener(String key, String group, ConfigurationListener listener) Stops one listener from listening to value changes in the specified key.

方法详细资料

addListener

public void addListener(String key,
                        String group,
                        ConfigurationListener listener)

Since all governance rules will lay under dubbo group, this method now always uses the default dubboConfig and ignores the group parameter.

指定者:

addListener 在接口中 DynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

listener - configuration listener

removeListener

public void removeListener(String key,
                           String group,
                           ConfigurationListener listener)

从接口复制的说明: DynamicConfiguration

Stops one listener from listening to value changes in the specified key.

指定者:

removeListener 在接口中 DynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

listener - configuration listener

getConfig

public String getConfig(String key,
                        String group,
                        long timeout)
                 throws IllegalStateException

从接口复制的说明: DynamicConfiguration

Get the configuration mapped to the given key and the given group. If the configuration fails to fetch after timeout exceeds, IllegalStateException will be thrown.

指定者:

getConfig 在接口中 DynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

timeout - timeout value for fetching the target config

返回:

target configuration mapped to the given key and the given group, IllegalStateException will be thrown if timeout exceeds.

抛出:

IllegalStateException

getProperties

public String getProperties(String key,
                            String group,
                            long timeout)
                     throws IllegalStateException

Recommend specify namespace and group when using Apollo.

, 'dubbo=governance' is for governance rules while 'group=dubbo' is for properties files.

指定者:

getProperties 在接口中 DynamicConfiguration

参数:

key - default value is 'dubbo.properties', currently useless for Apollo.

group -

timeout -

返回:

抛出:

IllegalStateException

getInternalProperty

public String getInternalProperty(String key)

This method will be used by Configuration to get valid value at runtime. The group is expected to be 'app level', which can be fetched from the 'config.appnamespace' in url if necessary. But I think Apollo's inheritance feature of namespace can solve the problem .

指定者:

getInternalProperty 在接口中 Configuration
