I’m trying to validate a simple form in JSP with Spring and Hibernate using

  • 0

I’m trying to validate a simple form in JSP with Spring and Hibernate using HibernateValidator. The JSP page Temp.jsp is as follows (the url pttern in web.xml is *.htm).

<%@page contentType="text/html" pageEncoding="UTF-8" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form" %>

<form:form method="post" action="Temp.htm" commandName="validationForm">
     <!--validationForm is a model class-->
<table>
    <tr>
        <td>User Name:<font color="red"><form:errors path="userName" /></font></td>
    </tr>

    <tr>
        <td><form:input path="userName" /></td>
    </tr>

    <tr>
        <td>Age:<font color="red"><form:errors path="age" /></font></td>
    </tr>

    <tr>
        <td><form:input path="age" /></td>
    </tr>

    <tr>
        <td>Password:<font color="red"><form:errors path="password" /></font></td>
    </tr>

    <tr>

    <td><form:password path="password" /></td>

    </tr>

    <tr>
        <td><input type="submit" value="Submit" /></td>
    </tr>
    </table>

</form:form>

The class validationForm is as follows.

package validators;

import javax.validation.constraints.Max;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.NotEmpty;
import org.springframework.format.annotation.NumberFormat;
import org.springframework.format.annotation.NumberFormat.Style;

final public class ValidationForm
{
    @NotEmpty
    @Size(min = 1, max = 20)
    private String userName;
    @NotNull
    @NumberFormat(style = Style.NUMBER)
    @Min(1)
    @Max(110)
    private Integer age;
    @NotEmpty(message = "Password must not be blank.")
    @Size(min = 1, max = 10, message = "Password must between 1 to 10 Characters.")
    private String password;

    public void setUserName(String userName)
    {
            this.userName = userName;
    }

    public String getUserName()
    {
            return userName;
    }

    public void setAge(Integer age)
    {
            this.age = age;
    }

    public Integer getAge()
    {
            return age;
    }

    public void setPassword(String password)
    {
            this.password = password;
    }

    public String getPassword()
    {
            return password;
    }
}

and the Controller class where the validation should be processed is as follows (I’m using SimpleFormController).

package controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import usebeans.TempService;
import validators.ValidationForm;

@SuppressWarnings("deprecation")
final public class Temp extends SimpleFormController 
{
    private TempService tempService=null;
    public Temp()
    {
        //setCommandClass(Temp.class);
        //setSuccessView("Temp");
        //setFormView("Temp");

        setCommandClass(ValidationForm.class); //Still not working.
        setCommandName("validationForm");
    }   

    public void setTempService(TempService tempService)
    {
        this.tempService = tempService;
    }

    @Override
    protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception
    {
        ModelAndView mv=new ModelAndView();
        ValidationForm validationForm=(ValidationForm) command;
        tempService.add(validationForm);
        return mv;
    }

    @Override
    protected ModelAndView showForm(HttpServletRequest request, HttpServletResponse response, BindException errors) throws Exception
    {
        ModelAndView mv=new ModelAndView();
        return mv;
    }
}

In dispatcher-servlet, I have added the following.

<bean id="tempService" class="usebeans.TempServiceImpl" />
<bean name="/Temp.htm" class="controller.Temp" p:tempService-ref="tempService" p:formView="Temp" p:successView="Temp" />

Also tried adding the following bean still there is no luck.

<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>

Where the TempService interface is as follows.

package usebeans;

import validators.ValidationForm;

public interface  TempService
{
    public void add(ValidationForm validationForm);
}

and following is the TempServiceImpl class.

package usebeans;

import validators.ValidationForm;

final public class TempServiceImpl implements TempService
{
    public void add(ValidationForm validationForm)
    {
        System.out.println("Message");
    }
}

Although the class TempServiceImpl implements the TempService interface, I’m getting the following exception.

javax.servlet.ServletException: No adapter for handler [usebeans.TempServiceImpl@ab3cba]: Does your handler implement a supported interface like Controller?

Edit :

Although I’m following what is explained here, the problem remains and I’m getting the same exception as mentioned above. What configuration settings am I missing here. It may be in the dispatcher-servlet.xml file. The entire dispatcher-servlet.xml file is as follows.

</beans>

I don’t have any precise idea about that exception being thrown. Can you figure it out why is that exception being thrown? What configuration settings or something else am I missing here?

    I’ve fixed the issue, please find the new xml

    <bean

    <bean
        class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter" />


    <bean id="tempService" class="usebeans.TempServiceImpl" />
    <bean id="tempController" class="controller.Temp"/>


    <bean id="urlMapping"
        class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="index.htm">indexController</prop>
                <prop key="Temp.htm">tempController</prop> <!-- You need to mapp the url to the controller bean-->
            </props>
        </property>
    </bean>

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver"
        p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />

    <bean name="indexController"
        class="org.springframework.web.servlet.mvc.ParameterizableViewController"
        p:viewName="index" />

</beans>

    Fix was related to <prop key="Temp.htm">tempController</prop>.

    For the second error change the class Temp as below

    package controller;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import usebeans.TempService;
import validators.ValidationForm;

@SuppressWarnings("deprecation")
final public class Temp extends SimpleFormController {
    private TempService tempService = null;

    public Temp() {
        // setCommandClass(Temp.class);
        // setSuccessView("Temp");
        // setFormView("Temp");

        setCommandClass(ValidationForm.class); // Still not working.
        setCommandName("validationForm");
    }

    public void setTempService(TempService tempService) {
        this.tempService = tempService;
    }

    @Override
    protected ModelAndView onSubmit(HttpServletRequest request,
            HttpServletResponse response, Object command, BindException errors)
            throws Exception {
        ModelAndView mv = new ModelAndView();
        ValidationForm validationForm = (ValidationForm) command;
        tempService.add(validationForm);
        return mv;
    }

    @Override
    protected ModelAndView showForm(HttpServletRequest request,
            HttpServletResponse response, BindException errors)
            throws Exception {
        Map<String, Object> model = new HashMap<String, Object>();
        model.put(getCommandName(), new ValidationForm());
        ModelAndView mv = new ModelAndView("Temp", model);
        return mv;
    }
}
