initialize

public void initialize()
                throws IllegalStateException

从接口复制的说明: Lifecycle

Initialize the component before start

指定者:

initialize 在接口中 Lifecycle

覆盖:

initialize 在类中 LifecycleAdapter

抛出:

IllegalStateException

Merge target map properties into app configuration

参数:

getPrefixedConfiguration

public Configuration getPrefixedConfiguration(AbstractConfig config,
                                              String prefix)

At start-up, Dubbo is driven by various configuration, such as Application, Registry, Protocol, etc. All configurations will be converged into a data bus - URL, and then drive the subsequent process.

At present, there are many configuration sources, including AbstractConfig (API, XML, annotation), - D, config center, etc. This methood helps us t filter out the most priority values from various configuration sources.

参数:

config -

prefix -

返回:

getConfiguration

public CompositeConfiguration getConfiguration()

There are two ways to get configuration during exposure / reference or at runtime: 1. URL, The value in the URL is relatively fixed. we can get value directly. 2. The configuration exposed in this method is convenient for us to query the latest values from multiple prioritized sources, it also guarantees that configs changed dynamically can take effect on the fly.

getConfigurationMaps

public List<Map<String,String>> getConfigurationMaps(AbstractConfig config,
                                                           String prefix)

Get configuration map list for target instance

参数:

config -

prefix -

返回:

getConfigurationMaps

public List<Map<String,String>> getConfigurationMaps()

Get global configuration as map list

返回:

destroy

public void destroy()
             throws IllegalStateException

从接口复制的说明: Lifecycle

指定者:

destroy 在接口中 Disposable

指定者:

destroy 在接口中 Lifecycle

覆盖:
