构造器详细资料

FieldError

public FieldError(String objectName,
                  String field,
                  String defaultMessage)

Create a new FieldError instance.

参数:

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,
                  @Nullable
                  Object rejectedValue,
                  boolean bindingFailure,
                  @Nullable
                  String[] codes,
                  @Nullable
                  Object[] arguments,
                  @Nullable
                  String defaultMessage)

Create a new FieldError instance.

参数:

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

方法详细资料

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)

覆盖:

equals 在类中 ObjectError

hashCode

public int hashCode()

覆盖:

hashCode 在类中 ObjectError

toString

public String toString()

从类复制的说明: DefaultMessageSourceResolvable

The default implementation exposes the attributes of this MessageSourceResolvable.

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

覆盖:

toString 在类中 ObjectError
