Question

Having big problems with Hibernate Validator

Getting this error

java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name ‘company’ available as request attribute

Here is my Controller

 import java.util.logging.Logger;

 import javax.validation.Valid;

 import org.springframework.stereotype.Controller;
 import org.springframework.ui.ModelMap;
 import org.springframework.validation.BindingResult;
 import org.springframework.web.bind.annotation.ModelAttribute;
 import org.springframework.web.bind.annotation.RequestMapping;
 import org.springframework.web.bind.annotation.RequestMethod;
 import org.springframework.web.bind.annotation.SessionAttributes;

 import com.muuves.reservosity.model.Business_Register;

 @Controller
 @SessionAttributes( {"company"})
 @RequestMapping("/business")
 public class BusinessController {
private final static Logger LOG = Logger.getLogger(BusinessController.class .getName()); 


@RequestMapping(method = RequestMethod.GET)
public String business(ModelMap model) {
    LOG.info("Entering Business Home");
    model.put("company", new Business_Register());
    return "business";
}
@RequestMapping(value="/register", method = RequestMethod.GET)
public String businessRegister() {
    LOG.info("Register Business Page");
    return "business_register";
}

@RequestMapping(value = "/add", method = RequestMethod.POST)
public String addBusiness(@Valid Business_Register company, BindingResult result, ModelMap model) {
    LOG.info("Registering Business"+result.getErrorCount());
    if (result.hasErrors()){
        System.out.println("I found errors now now");
        return "business_register";
    }
    //companyService.addCompany(company);
    return "business_add";
}

}

This is jsp

    </dependency>

Answer 1

Needed to add @ModelAttribute(“company”) http://blog.nigelsim.org/2011/09/07/spring-mvc-validation-bindingresult/

And it works

Seems ridiculous that you needed to do this though
