方法详细资料

• getPath

  public String getPath()

  Return the bean and property path for which values and errors will be resolved (e.g. "customer.address.street").

• getExpression

  @Nullable
  public String getExpression()

  Return a bind expression that can be used in HTML forms as input name for the respective field, or null if not field-specific.

  Returns a bind path appropriate for resubmission, e.g. "address.street". Note that the complete bind path as required by the bind tag is "customer.address.street", if bound to a "customer" bean.

• getValue

  @Nullable
  public Object getValue()

  Return the current value of the field, i.e. either the property value or a rejected update, or null if not field-specific.

  This value will be an HTML-escaped String if the original value already was a String.

• getValueType

  @Nullable
  public Class<?> getValueType()

  Get the 'Class' type of the field. Favor this instead of 'getValue().getClass()' since 'getValue()' may return 'null'.

• getActualValue

  @Nullable
  public Object getActualValue()

  Return the actual value of the field, i.e. the raw property value, or null if not available.

• getDisplayValue

  public String getDisplayValue()

  Return a suitable display value for the field, i.e. the stringified value if not null, and an empty string in case of a null value.

  This value will be an HTML-escaped String if the original value was non-null: the toString result of the original value will get HTML-escaped.

  public boolean isError()

  Return if this status represents a field or object error.
