Class BindException

java.lang.Object
java.lang.Throwable
java.lang.Exception
org.springframework.validation.BindException
All Implemented Interfaces:
Serializable, BindingResult, Errors
Direct Known Subclasses:
MethodArgumentNotValidException
public class BindException extends Exception implements BindingResult
Thrown when binding errors are considered fatal. Implements the 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

      public BindException(BindingResult bindingResult)
      Create a new BindException instance for a BindingResult.
      Parameters:
      bindingResult - the BindingResult instance to wrap

    • BindException

      public BindException(Object target, String objectName)

  • Method Details

    • getBindingResult

      public final BindingResult getBindingResult()
      Return the BindingResult that this BindException wraps.

    • getObjectName

      public String getObjectName()
      Description copied from interface: Errors
      Return the name of the bound root object.
      Specified by:
      getObjectName in interface Errors

    • setNestedPath

      public void setNestedPath(String nestedPath)
      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 interface Errors
      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.

    • getNestedPath

      public String getNestedPath()
      Description copied from interface: Errors
      Return the current nested path of this Errors 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 interface Errors

    • pushNestedPath

      public void pushNestedPath(String subPath)
      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 corresponding pushNestedPath(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 interface Errors
      Parameters:
      subPath - the sub path to push onto the nested path stack
      See Also:

    • popNestedPath

      public void popNestedPath() throws IllegalStateException
      Description copied from interface: Errors
      Pop the former nested path from the nested path stack.
      Specified by:
      popNestedPath in interface Errors
      Throws:
      IllegalStateException - if there is no former nested path on the stack

      public void rejectValue(@Nullable String field, String errorCode)
      Description copied from interface: Errors
      Register a field error for the specified field of the current object (respecting the current nested path, if any), using the given error description.

      The field name may be null or empty String to indicate the current object itself rather than a field of it. This may result in a corresponding field error within the nested object graph or a global error if the current object is the top object.

      Specified by:
      rejectValue in interface Errors
      Parameters:
      field - the field name (may be null or empty String)

      Allows for convenient access to user-specified field values, even if there were type mismatches.

      Specified by:

      Parameters:
      field - the field name
      Returns:
      the current value of the given field

      @Nullable public Class<?> getFieldType(String field)
      Description copied from interface: Errors
      Return the type of a given field.

      Specified by:
      getFieldType in interface Errors

      field - the field name
      Returns:
      the type of the field, or null if not determinable

    • getTarget

      @Nullable public Object getTarget()
      Description copied from interface: BindingResult
      Return the wrapped target object, which may be a bean, an object with public fields, a Map - depending on the concrete binding strategy.
      Specified by:
      getTarget in interface BindingResult

    • getModel

      public Map<String,Object> getModel()
      Description copied from interface: BindingResult
      Return a model Map for the obtained state, exposing a BindingResult instance as 'MODEL_KEY_PREFIX + objectName' and the object itself as 'objectName'.

      Note that the Map is constructed every time you're calling this method. Adding things to the map and then re-calling this method will not work.

      The attributes in the model Map returned by this method are usually included in the ModelAndView for a form view that uses Spring's bind 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 in interface BindingResult
