构造器详细资料

PropertySourcesPropertyResolver

public PropertySourcesPropertyResolver(@Nullable
 PropertySources propertySources)

Create a new resolver against the given property sources.

参数:

propertySources - the set of PropertySource objects to use

方法详细资料

containsProperty

public boolean containsProperty(String key)

从接口复制的说明: PropertyResolver

Return whether the given property key is available for resolution, i.e. if the value for the given key is not null.

指定者:

containsProperty 在接口中 PropertyResolver

覆盖:

containsProperty 在类中 AbstractPropertyResolver

getProperty

@Nullable
public <T> T getProperty(String key,
 Class<T> targetValueType,
 boolean resolveNestedPlaceholders)

指定者:

getProperty 在类中 TypedPropertyResolver

logKeyFound

protected void logKeyFound(String key,
 PropertySource<?> propertySource,
 Object value)

Log the given key as found in the given PropertySource, resulting in the given value.

The default implementation writes a debug log message with key and source. this does not log the value anymore in order to avoid accidental logging of sensitive settings. Subclasses may override this method to change the log level and/or log message, including the property's value if desired.

参数:

key - the key found

propertySource - the PropertySource that the key has been found in

value - the corresponding value

getPropertyNames

public ArrayList<String> getPropertyNames()

iterator

public Iterator<String> iterator()

从接口复制的说明: IterablePropertyResolver

Returns an iterator of property-names.

指定者:

iterator 在接口中 Iterable<String>

指定者:

iterator 在接口中 IterablePropertyResolver

返回:

a property-names Iterator.

forEach

public void forEach(Consumer<? super String> action)

指定者:

forEach 在接口中 Iterable<String>

spliterator

public Spliterator<String> spliterator()

指定者:

spliterator 在接口中 Iterable<String>
