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) This method will be used to: 1. get configuration file at startup phase 2. get all kinds of Dubbo rules
String	getConfigs(String key, String group, long timeout) DynamicConfiguration.getConfig(String, String, long) This method are mostly used to get a compound config file, such as a complete dubbo.properties file.
String	getInternalProperty(String key) This method will be used by Configuration to get valid value at runtime.
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

This method will be used to: 1. get configuration file at startup phase 2. get all kinds of Dubbo rules

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

getConfigs

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

从接口复制的说明: DynamicConfiguration

DynamicConfiguration.getConfig(String, String, long) This method are mostly used to get a compound config file, such as a complete dubbo.properties file.

指定者:

getConfigs 在接口中 DynamicConfiguration

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
