注释InitBinder没有调用

Question

在我的应用程序中我有控制器：

package org.sample.web.config;

import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.sample.model.Contact;
import org.sample.model.Person;
import org.sample.model.PersonGender;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.RequestMapping;

import ch.ralscha.extdirectspring.generator.IncludeValidation;
import ch.ralscha.extdirectspring.generator.ModelGenerator;
import ch.ralscha.extdirectspring.generator.OutputFormat;

@Controller
@RequestMapping
public class ModelController {
    private final Logger logger = LoggerFactory.getLogger(getClass());

    @InitBinder
    public void initBinder(WebDataBinder binder) {
        logger.error("aaaaaaaaaaaaaaa");
        binder.registerCustomEditor(PersonGender.class, new EnumPropertyEditor(PersonGender.class));
    }

    @RequestMapping("/app/model/Person.js")
    public void user(HttpServletRequest request, HttpServletResponse response) throws IOException {
        ModelGenerator.writeModel(request, response, Person.class, OutputFormat.EXTJS4, IncludeValidation.ALL, true);
    }

    @RequestMapping("/app/model/Contact.js")
    public void catalog(HttpServletRequest request, HttpServletResponse response) throws IOException {
        ModelGenerator.writeModel(request, response, Contact.class, OutputFormat.EXTJS4, IncludeValidation.ALL, true);
    }

}

问题是带有注释InitBinder的方法永远不会调用，所以当我想验证我的enut时它会引发异常：

编辑：

PersonGender:

package org.sample.model;

import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;

public enum PersonGender implements Serializable {

  MALE("M"), FEMALE("F"), UNKNOWN("0");

  private static final long serialVersionUID = 1L;

  private static Map<String, PersonGender> identifierMap = new HashMap<String, PersonGender>();

    static {
        for (PersonGender value : PersonGender.values()) {
            identifierMap.put(value.getValue(), value);
        }
    }

    private String value;

    private PersonGender(String value) {
        this.value = value;
    }

    public static PersonGender fromValue(String value) {
        PersonGender result = identifierMap.get(value);
        if (result == null) {
            throw new IllegalArgumentException("No PersonGender for value: " + value);
        }
        return result;
    }

    public String getValue() {
        return value;
    }

    public String getName() {
        return name();
    }
}

提交表格时会发生异常：

@Service
public class SimpleService {
...
    @ExtDirectMethod(value = ExtDirectMethodType.FORM_POST, group = "person")
    public ExtDirectFormPostResult validatePersonForm(@Valid Person p, BindingResult result) {
        if (!result.hasErrors()) {
            // another validations
        }
        return new ExtDirectFormPostResult(result);
    }
...
}
