NestedIOException (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - java.io.IOException
    - - org.springframework.core.NestedIOException

所有已实现的接口:
Serializable
```
public class NestedIOException
extends IOException
```
Subclass of IOException that properly handles a root cause, exposing the root cause just like NestedChecked/RuntimeException does.
Proper root cause handling has not been added to standard IOException before Java 6, which is why we need to do it ourselves for Java 5 compatibility purposes.
The similarity between this class and the NestedChecked/RuntimeException class is unavoidable, as this class needs to derive from IOException.
