ResourceBundleMessageSource.getStringOrNull介绍

[英]Efficiently retrieve the String value for the specified key, or return null if not found.

As of 4.2, the default implementation checks containsKeybefore it attempts to call getString (which would require catching MissingResourceException for key not found).

Can be overridden in subclasses.
[中]高效地检索指定键的字符串值，如果找不到，则返回null。
从4.2开始，默认实现会在尝试调用getString之前检查ContainesKeyBefore（这需要捕获未找到密钥的MissingResourceException）。
可以在子类中重写。
