• getProperty

  @Nullable
  public String getProperty​(String key)

  从接口复制的说明: PropertyResolver
  Return the property value associated with the given key, or null if the key cannot be resolved.

  指定者:

  getProperty 在接口中 PropertyResolver

  覆盖:

  getProperty 在类中 AbstractPropertyResolver

  参数:

  key - the property name to resolve

  PropertyResolver.getProperty(String, String), PropertyResolver.getProperty(String, Class), PropertyResolver.getRequiredProperty(String)

• getProperty

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

  从接口复制的说明: PropertyResolver
  Return the property value associated with the given key, or null if the key cannot be resolved.

  参数:

  key - the property name to resolve

  targetValueType - the expected type of the property value

  另请参阅:

  PropertyResolver.getRequiredProperty(String, Class)

• getPropertyAsRawString

  @Nullable
  protected String getPropertyAsRawString​(String key)

  从类复制的说明: AbstractPropertyResolver
  Retrieve the specified property as a raw String, i.e. without resolution of nested placeholders.

  指定者:

  getPropertyAsRawString 在类中 AbstractPropertyResolver

  参数:

  key - the property name to resolve

  返回:

  the property value or null if none found

• getProperty

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

• 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. As of 4.3.3, 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

  从以下版本开始:

  4.3.1
