I am getting this error "Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister"?

I am trying to make a spring-hibernate application but I am getting this error
Request processing failed; nested exception is org.hibernate.MappingException: Could not get constructor for org.hibernate.persister.entity.SingleTableEntityPersister
I know this error comes when it tries to find getters and setters and couldn't get them. But i checked my getters and setters properly they are correct.
Please help me with this.
My Structure is like this
And code is
Employee.java
package com.wipro.config;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="empdata")

#Id
private String empname;
#Column(name="designation",length=15)
private String designation;
#Column(name="email",length=25)
private String email;
public String getEmpname() {
return empname;
}
public void setEmpname(String empname) {
this.empname = empname;
}
public String getDesignation() {
return designation;
}
public void setDesignation(String designation) {
this.designation = designation;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}

<h2>Hello World!</h2>

I solved this issue by adding a no argument constractor. If you are using Lombok, you only need to add #NoArgsConstructor annotation:
#AllArgsConstructor
#NoArgsConstructor
#Getter
#ToString
#EqualsAndHashCode
public class User {
private Long userId;
private String shortName;
}

Hibernate Validator #NotNull not working properly

I am trying to make simple validation form using Hibernate Validator. I have two fields in my Customer class, and i want one of them to be required (lastName).
The point is that even when im not filling this field I am not getting error message and BindingResult does not contain any errors. Is there anything im missing in my code?
Here is my Customer class snippet.
public class Customer {
private String firstName;
#NotNull(message = "is required")
#Size(min = 1, message = "is required")
private String lastName;
public String getFirstName() {
return firstName;
}
public String getLastName() {
return lastName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
Here is Controller
#Controller
#RequestMapping("/customer")
public class CustomerController {
//adding new customer to model
#RequestMapping("/showForm")
public String showForm(Model theModel){
theModel.addAttribute("customer", new Customer());
return "customer-form";
}
//Validating passed customer attribute/object
//Biding result object holds validation results
#RequestMapping("/processForm")
public String processForm(
#Valid #ModelAttribute("customer") Customer theCustomer, BindingResult theBindingResult) {
if (theBindingResult.hasErrors()){
return "customer-form";
}
return "customer-confirmation";
}
}
EDIT: form code:
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%# page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Customer Registration Form</title>
</head>
<body>
<style>
.error{color: red}
</style>
<i> Fill out the form. Asteriks (*) means required. </i>
<br><br>
<form:form action="processForm" modelAttribute="customer">
First name: <form:input path="firstName" />
<br><br>
Last name (*): <form:input path="lastName"/>
<form:errors path="lastName" cssClass="error" />
<input type="submit" value="Submit"/>
</form:form>
</body>
</html>
EDIT 2:
I added to classpath validation-api.jar (contains the abstract API and the annotation scanner).
Also inserted #InitBinnder just to make sure that empty form field will always be null not empty String.
#InitBinder
public void initBinder(WebDataBinder dataBinder) {
StringTrimmerEditor stringTrimmerEditor = new StringTrimmerEditor(true);
dataBinder.registerCustomEditor(String.class, stringTrimmerEditor);
}
But it still seems that those annotations never get triggered at all
EDIT 3: After calling validator on Entity I am getting error:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is javax.validation.NoProviderFoundException: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.
although i have added it to classpath
ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
Validator validator = factory.getValidator();
validator.validate(theCustomer);
EDIT 4: Adding Spring Configuration files:
web.xml
<?xml version="1.0" encoding="UTF-8"?>

</bean>
</beans>
EDIT 5: According to what #eis said i added to my mvc-validation-demo.xml:
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalVa‌​lidatorFactoryBean"/‌​>
And i also have Hibernate Validator in my classpath:
Classpath
but the error still remains

Deleteing .idea , clearing cache and new configuration did the job for me. It seems that somehow it didn't saw hibernate-validator.jar.
Thank you to everyone who contributed.

Hello there

when I try running this program it gives me error as 404 suggested URL is not present.

I think that the problem is that your project doesn't include all the libraries. so If you'are using Eclipse and Maven go to
Project Properties -> Deployment Assembly -> Add -> Java Build Path Entries -> Maven Dependencies.

the above code is almost similar to the book code but still I am unable to find where is the mistake.I attached an #RequestMapping attribute to the list() and member() methods,This identifies them as request-servicing methods.Below is my project structure screenshot.

You need to add * after /roster/ in your bean definition.
Try following setting:
<bean class="com.web.RosterController" name="/roster/*"></bean>
instead of
<bean class="com.web.RosterController" name="/roster/"></bean>
And access /MVC_BOOK_Annotation/main/roster/list.do

You are using #RequestMapping without value-parameter, that way requests to your path wont get catched.
How to use #requestMapping headers?
I highly recommend reading all of this, without that knowledge you wont get far ...

You are using annotations to search your controller. You should be using the below code.
context:component-scan base-package="com"
tag in your Main-servlet

You need to add the below mapping:
<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
<!-- Enables the Spring MVC #Controller programming model -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:annotation-driven />
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<!-- <resources mapping="/resources/**" location="/resources/" /> -->
<!-- <mvc:resources mapping="/resources/**" location="/, classpath:/META-INF/public-web-resources/"/> -->
<!-- Resolves views selected for rendering by #Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
<!-- View Handler -->
<beans:bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<beans:property name="favorPathExtension" value="true"/>
<beans:property name="mediaTypes">
<beans:map>
<beans:entry key="xml" value="text/xml"/>
<beans:entry key="json" value="application/json"/>
<beans:entry key="html" value="text/html"/>
<beans:entry key="less" value="text/html"/>
</beans:map>
</beans:property>
<beans:property name="viewResolvers">
<beans:list>
<beans:bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<beans:property name="viewClass" value="org.springframework.web.servlet.view.tiles3.TilesView"/>
</beans:bean>
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

new to spring, not able to delete user using hibernate

I am new to spring, was working on an example. The example shows how to add data to table using hibernate and list it also, I tried to add extra delete option but its updating record instead. I will post complete code below. ( 2 ) I develop simple web apps using jsp and servlets and lots of jquery ajax, I want to use ajax also with spring, will I be able to code the same way or its something different which i have to learn. To be frank I am scared after seeing the spring pattern.. :).

In your dispatcherservlet.xml please comment the below line
<prop key="hibernate.hbm2ddl.auto">create</prop>
as everytime when you restart your server, it will auto create the table when server starts. Please check the mapping correctly for deleting the user and have print or breakpoints and debug the issue, seeing your code hibernateTemplate.delete(user) should work fine.
