构造器详细资料

ObjectError

public ObjectError(String objectName,
 String defaultMessage)

Create a new instance of the ObjectError class.

参数:

objectName - the name of the affected object

defaultMessage - the default message to be used to resolve this message

ObjectError

public ObjectError(String objectName,
 @Nullable
 String[] codes,
 @Nullable
 Object[] arguments,
 @Nullable
 String defaultMessage)

Create a new instance of the ObjectError class.

参数:

objectName - the name of the affected object

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

getObjectName

public String getObjectName()

Return the name of the affected object.

wrap

public void wrap(Object source)

Preserve the source behind this error: possibly an Exception (typically PropertyAccessException) or a Bean Validation ConstraintViolation.

Note that any such source object is being stored as transient: that is, it won't be part of a serialized error representation.

参数:

source - the source object

unwrap

public <T> T unwrap(Class<T> sourceType)

Unwrap the source behind this error: possibly an Exception (typically PropertyAccessException) or a Bean Validation ConstraintViolation.

The cause of the outermost exception will be introspected as well, e.g. the underlying conversion exception or exception thrown from a setter (instead of having to unwrap the PropertyAccessException in turn).

返回:

the source object of the given type

抛出:

IllegalArgumentException - if no such source object is available (i.e. none specified or not available anymore after deserialization)

contains

public boolean contains(Class<?> sourceType)

Check the source behind this error: possibly an Exception (typically PropertyAccessException) or a Bean Validation ConstraintViolation.

The cause of the outermost exception will be introspected as well, e.g. the underlying conversion exception or exception thrown from a setter (instead of having to unwrap the PropertyAccessException in turn).

返回:

whether this error has been caused by a source object of the given type

equals

public boolean equals(@Nullable
 Object other)

覆盖:

equals 在类中 DefaultMessageSourceResolvable

hashCode

public int hashCode()

覆盖:

hashCode 在类中 DefaultMessageSourceResolvable

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 DefaultMessageSourceResolvable
