## Class FieldError

- java.lang.Object
- - org.springframework.context.support.DefaultMessageSourceResolvable
  - - org.springframework.validation.ObjectError
    - - org.springframework.validation.FieldError

- All Implemented Interfaces:
    Serializable, MessageSourceResolvable

      public class FieldError
      extends ObjectError

  Encapsulates a field error, that is, a reason for rejecting a specific field value.

  See the `DefaultMessageCodesResolver` javadoc for details on how a message code list is built for a `FieldError`.

    `Object` | `getRejectedValue()` Return the rejected field value.
    `int` | `hashCode()`
    `boolean` | `isBindingFailure()` Return whether this error represents a binding failure (like a type mismatch); otherwise it is a validation failure.

                            String defaultMessage)

      Create a new FieldError instance.
      Parameters:
        `objectName` - the name of the affected object
        `field` - the affected field of the object
        `defaultMessage` - the default message to be used to resolve this message

    - #### FieldError

          public FieldError(String objectName,
                            String field,

                            String defaultMessage)

      Create a new FieldError instance.
      Parameters:
        `objectName` - the name of the affected object
        `field` - the affected field of the object
        `rejectedValue` - the rejected field value
        `bindingFailure` - whether this error represents a binding failure (like a type mismatch); else, it is a validation failure
        `codes` - the codes to be used to resolve this message
        `arguments` - the array of arguments to be used to resolve this message
        `defaultMessage` - the default message to be used to resolve this message

  - ### Method Detail

    - #### getField

          public String getField()

      Return the affected field of the object.

    - #### getRejectedValue

          @Nullable
          public Object getRejectedValue()

      Return the rejected field value.

    - #### isBindingFailure

          public boolean isBindingFailure()

      Return whether this error represents a binding failure (like a type mismatch); otherwise it is a validation failure.

    - #### equals

          public boolean equals(@Nullable
                                Object other)

      Overrides:
        `hashCode` in class `ObjectError`

    - #### toString

          public String toString()

      Description copied from class: `DefaultMessageSourceResolvable`
      The default implementation exposes the attributes of this MessageSourceResolvable.

      To be overridden in more specific subclasses, potentially including the resolvable content through `resolvableToString()`.

      Overrides:
        `toString` in class `ObjectError`
