Class BindException
- All Implemented Interfaces:
Serializable
,BindingResult
,Errors
- Direct Known Subclasses:
MethodArgumentNotValidException
BindingResult
interface (and its super-interface Errors
)
to allow for the direct analysis of binding errors.
As of Spring 2.0, this is a special-purpose class. Normally,
application code will work with the BindingResult
interface,
or with a DataBinder
that in turn exposes a BindingResult via
DataBinder.getBindingResult()
.

Constructor Details
-
BindException
Create a new BindException instance for a BindingResult.- Parameters:
bindingResult
- the BindingResult instance to wrap
-
BindException
Create a new BindException instance for a target bean.- Parameters:
target
- the target bean to bind ontoobjectName
- the name of the target object- See Also:
-
-
Method Details
-
getBindingResult
Return the BindingResult that this BindException wraps. -
getObjectName
Description copied from interface:Errors
Return the name of the bound root object.- Specified by:
getObjectName
in interfaceErrors
-
setNestedPath
Description copied from interface:Errors
Allow context to be changed so that standard validators can validate subtrees. Reject calls prepend the given path to the field names.For example, an address validator could validate the subobject "address" of a customer object.
- Specified by:
setNestedPath
in interfaceErrors
- Parameters:
nestedPath
- nested path within this object, e.g. "address" (defaults to "",null
is also acceptable). Can end with a dot: both "address" and "address." are valid.- See Also:
-
getNestedPath
Description copied from interface:Errors
Return the current nested path of thisErrors
object.Returns a nested path with a dot, i.e. "address.", for easy building of concatenated paths. Default is an empty String.
- Specified by:
getNestedPath
in interfaceErrors
- See Also:
-
pushNestedPath
Description copied from interface:Errors
Push the given sub path onto the nested path stack.A
Errors.popNestedPath()
call will reset the original nested path before the correspondingpushNestedPath(String)
call.Using the nested path stack allows to set temporary nested paths for subobjects without having to worry about a temporary path holder.
For example: current path "spouse.", pushNestedPath("child") → result path "spouse.child."; popNestedPath() → "spouse." again.
- Specified by:
pushNestedPath
in interfaceErrors
- Parameters:
subPath
- the sub path to push onto the nested path stack- See Also:
-
popNestedPath
Description copied from interface:Errors
Pop the former nested path from the nested path stack.- Specified by:
popNestedPath
in interfaceErrors
- Throws:
IllegalStateException
- if there is no former nested path on the stack- See Also:
-

The attributes in the model Map returned by this method are usually included in the
ModelAndView
for a form view that uses Spring'sbind
tag in a JSP, which needs access to the BindingResult instance. Spring's pre-built form controllers will do this for you when rendering a form view. When building the ModelAndView instance yourself, you need to include the attributes from the model Map returned by this method.- Specified by:
getModel
