Simply calls Object#toString() to convert any supported object to a String.

Supports CharSequence, StringWriter, and any class with a String constructor or one of the following static factory methods: valueOf(String), of(String), from(String).

Used by the DefaultConversionService as a fallback if there are no other explicit to-String converters registered.

Implements org.springframework.core.convert.converter.GenericConverter.getConvertibleTypes.

Doc from org.springframework.core.convert.converter.GenericConverter.getConvertibleTypes.

Return the source and target types that this converter can convert between.

Each entry is a convertible source-to-target type pair.

For conditional converters this method may return null to indicate all source-to-target pairs should be considered.
