方法概要

限定符和类型	方法和说明
void	addListener(String key, String group, ConfigurationListener listener) Register a configuration listener for a specified key The listener only works for service governance purpose, so the target group would always be the value user specifies at startup or 'dubbo' by default.
String	getConfig(String key, String group, long timeout) Get the configuration mapped to the given key and the given group.
SortedSet<String>	getConfigKeys(String group) TODO Nacos does not support atomic update of the value mapped to a key.

Object	getInternalProperty(String key)
boolean	publishConfig(String key, String group, String content) Publish Config mapped to the given key and the given group.
boolean	removeConfig(String key, String group)
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)

从接口复制的说明: DynamicConfiguration

Register a configuration listener for a specified key The listener only works for service governance purpose, so the target group would always be the value user specifies at startup or 'dubbo' by default. This method will only register listener, which means it will not trigger a notification that contains the current value.

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

getInternalProperty

public Object getInternalProperty(String key)

指定者:

getInternalProperty 在接口中 Configuration

publishConfig

public boolean publishConfig(String key,
                             String group,
                             String content)

从接口复制的说明: DynamicConfiguration

Publish Config mapped to the given key and the given group.

指定者:

publishConfig 在接口中 DynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

content - the content of configuration

返回:

true if success, or false

getDefaultTimeout

public long getDefaultTimeout()

从接口复制的说明: DynamicConfiguration

Get the default timeout for the operations in milliseconds

指定者:

getDefaultTimeout 在接口中 DynamicConfiguration

返回:

The default value is -1L

getConfigKeys

public SortedSet<String> getConfigKeys(String group)

TODO Nacos does not support atomic update of the value mapped to a key.

指定者:

getConfigKeys 在接口中 DynamicConfiguration

参数:

group - the specified group

返回:

removeConfig

public boolean removeConfig(String key,
                            String group)

指定者:

removeConfig 在接口中 DynamicConfiguration

参数:

key - the key to represent a configuration

group - the group where the key belongs to

返回:

true if success, or false
