convertIfNecessary
public <T> T convertIfNecessary(Object value, Class<T> requiredType) throws TypeMismatchException
从接口复制的说明:TypeConverterConvert the value to the required type (if necessary from a String).Conversions from String to any type will typically use the
setAsTextmethod of the PropertyEditor class, or a Spring Converter in a ConversionService.- 指定者:
convertIfNecessary在接口中TypeConverter- 参数:
value- the value to convertrequiredType- the type we must convert to (ornullif not known, for example in case of a collection element)- 返回:
- the new value, possibly the result of type conversion
- 抛出:
TypeMismatchException- if type conversion failed- 另请参阅:
PropertyEditor.setAsText(String),PropertyEditor.getValue(),ConversionService,Converter
