修饰符和类型	方法	说明
`boolean`	`containsProperty(String key)`	Return whether the given property key is available for resolution, i.e. if the value for the given key is not `null`.
`String`	`getProperty(String key)`	Return the property value associated with the given key, or `null` if the key cannot be resolved.
`<T> T`	`getProperty(String key, Class<T> targetValueType)`	Return the property value associated with the given key, or `null` if the key cannot be resolved.

`<T> Class<T>`	`getPropertyAsClass(String key, Class<T> targetValueType)`	已过时。
`protected String`	`getPropertyAsRawString(String key)`	Retrieve the specified property as a raw String, i.e. without resolution of nested placeholders.
`protected void`	`logKeyFound(String key, PropertySource<?> propertySource, Object value)`	Log the given key as found in the given `PropertySource`, resulting in the given 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:
