Element Detail

value

public abstract Class<? extends Binder>[] value

Specify the Binder implementations

Note each binder implementation must have different Binder.targetType()

model

public abstract String model

Optionally specify the model attribute name the binder should used to resolve request parameters into the domain model object. Example:

HTML code

  <form>  <input name=“u.name”>  <input name=“u.password” type=“password” > </form>  

Java code

  public Result createUser(@Binder(value = UserBinder.class, model = “u”) User user) {  … }  

If model is ignored, then implementation should use the parameter name (user) in our case to resolve the model instance; and the frontend developer shall not use u.name and u.password to refer the model, instead user.name and user.password shall be used

Default:

""
