public class DirectFieldAccessor
extends AbstractNestablePropertyAccessor

ConfigurablePropertyAccessor implementation that directly accesses instance fields. Allows for direct binding to fields instead of going through JavaBean setters.

As of Spring 4.2, the vast majority of the BeanWrapper features have been merged to AbstractPropertyAccessor, which means that property traversal as well as collections and map access is now supported here as well.

A DirectFieldAccessor's default for the "extractOldValueForEditor" setting is "true", since a field can always be read without side effects.

从以下版本开始:

2.0

构造器详细资料

DirectFieldAccessor

public DirectFieldAccessor(Object object)

Create a new DirectFieldAccessor for the given object.

参数:

object - object wrapped by this DirectFieldAccessor

DirectFieldAccessor

protected DirectFieldAccessor(Object object,
                              String nestedPath,
                              DirectFieldAccessor parent)

Create a new DirectFieldAccessor for the given object, registering a nested path that the object is in.

参数:

object - object wrapped by this DirectFieldAccessor

nestedPath - the nested path of the object

parent - the containing DirectFieldAccessor (must not be null)

方法详细资料

getLocalPropertyHandler

@Nullable
protected org.springframework.beans.DirectFieldAccessor.FieldPropertyHandler getLocalPropertyHandler(String propertyName)

从类复制的说明: AbstractNestablePropertyAccessor

Return a AbstractNestablePropertyAccessor.PropertyHandler for the specified local propertyName. Only used to reach a property available in the current context.

指定者:

getLocalPropertyHandler 在类中 AbstractNestablePropertyAccessor

参数:

propertyName - the name of a local property

返回:

the handler for that property, or null if it has not been found

newNestedPropertyAccessor

protected DirectFieldAccessor newNestedPropertyAccessor(Object object,
                                                        String nestedPath)

从类复制的说明: AbstractNestablePropertyAccessor

Create a new nested property accessor instance. Can be overridden in subclasses to create a PropertyAccessor subclass.

指定者:

newNestedPropertyAccessor 在类中 AbstractNestablePropertyAccessor

参数:

object - object wrapped by this PropertyAccessor

nestedPath - the nested path of the object

返回:

the nested PropertyAccessor instance

createNotWritablePropertyException

protected NotWritablePropertyException createNotWritablePropertyException(String propertyName)

从类复制的说明: AbstractNestablePropertyAccessor

Create a NotWritablePropertyException for the specified property.

指定者:

createNotWritablePropertyException 在类中 AbstractNestablePropertyAccessor
