Fetch value from Exception

Question

I am getting a NumberFormatException and i want to fetch the value from the exception itself , which looks like

But there is no getter available for the value, can anyone suggest any solution to fetch this value rather than reflection, or even reflection can be fine.

extend the Exception and add your own value/getter. What do you need it for, actually? — Stultuske, Dec 11 '15 at 11:48
@Stultuske How should an own Exception help here? Non of the used libraries would know this new exception type. — Tom, Dec 11 '15 at 12:01
@Stultuske : Thanks for your suggestion,but this exception is thrown by spring itself when it tries to map the request value using jackson — Anand Kadhi, Dec 11 '15 at 12:32

If you explicitly check for TypeMismatchException, you can retrieve that value simply by calling getValue()

http://docs.spring.io/spring-framework/docs/2.0.8/api/org/springframework/beans/TypeMismatchException.html#getValue()

You could get value from org.springframework.beans.TypeMismatchException just use Object getValue(), for example, using following code:

...
} catch(Exception exception) {
   if(exception instanceof TypeMismatchException) {
      Object value = ((TypeMismatchException) exp).getValue;
      ... // what you want to do with value
   }
}

or just

...
} catch(TypeMismatchException exception) {
      Object value = exp.getValue;
      ... // what you want to do with value
}

Because org.springframework.beans.TypeMismatchException define as

package org.springframework.beans;
public class TypeMismatchException extends PropertyAccessException {
...
    /**
     * Return the offending value (may be {@code null})
     */
    @Override
    public Object getValue() {
        return this.value;
    }
...
}
