Exception with InitBinder – SpringMVC

I’m using InitBinder to validate form submit, it’s working fine until I accessed to another screen and I received this error :

java.lang.IllegalStateException: Invalid target for Validator[com.mypackage.OrdersFormValidator@2882bdab]:

com.mypackage.OrderDashBoardSearch@2f9e7972 at org.springframework.validation.DataBinder.assertValidators(DataBinder.java:542)

at org.springframework.validation.DataBinder.setValidator(DataBinder.java:533)

at com.mhealth.apotikantar.backend.cms.controller.OrderController.initBinder(OrderController.java:135)

Here is my code in controller :


protected void initBinder(WebDataBinder binder) {



How can I prevent this and add InitBinder to only single method ?

With InitBinder, you can pass param to restrict some case only


The value of

can be one of the following

  • The name of a model attribute
  • The name of a request parameter
  • If none of the above apply, then the name of the class can be used, but starting with a small letter. That’s how Spring exposes unnamed attributes to the model.
