java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: User is not mapped [from User]

I'm getting java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: User is not mapped [from User] error. I've gone through these question, but didn't helped me.
org.hibernate.hql.internal.ast.QuerySyntaxException: table is not mapped

Help Please .. Thanks

#Table(name = ...) distinguishes the (resulting SQL) table name, bro!
#Entity(name = ...) distinguishes the "entity name" especially in jpql/hql/criteria queries - defaults to class name. – #xerx593

As I could see from your database scheme, column mapping names in UserBean.java are not correct (e.g. #Column(name="Username") while it should be lowercase). Possibly, the same problem with table name.
Could be a cause
Second possible option is that You didn't indicated to Hibernate what is the result entity. To do so replace createQuery("from User") with createQuery("from UserBean", UserBean.class)

can someone help me. i already search for similar problem, but still not get what the error.

You should add annotation #Inject or #Autowired for your RegisterController::userDAO field, then it will be properly initialized.

You have defined
private UserDAO userDAO;
And then you call
userDAO.create(whatever);
at this point in time, no value has been assigned to userDAO, hence, null. You need to instantiate the object.

It is complaining that a 'spring' database doesn't exist in mysql. Perhaps you have to create it before running the sample. It comes from the line:
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/spring</property>
In your hibernate.cfg.xml file. If you have a database with a different name you can change it there. Perhaps the sample comes with some script that you are meant to run which creates and populates the db.

so error is that table does not exist.
but not able to understand the reason
see in my hibernate.cfg.xml i have
<property name="hbm2ddl.auto">create</property>
which should be responsible to create the table.
Please help me out

that was the culprit.
cannot give it AUTO, while setting it of my own.
#Column
#Id #GeneratedValue(strategy=GenerationType.AUTO)
String EmailID;
removed the #GeneratedValue, now working fine.
might be helpful for someone later.

Session Factory in Spring and Hibernate

I'm new to Spring MVC and Hibernate and I'm having a problem with my session configurations. I have done this by using the hibernate. What I want to do now is that the sessionFactory will be autowired in the DAO.

You are missing "dao" package in your component-scan config:
<context:component-scan base-package="com.nutsaboutcandywebproject.controller"/>
<context:component-scan base-package="com.nutsaboutcandywebproject.dao"/>
Also, DAO class must have #Repository annotation in order to use it as an autowired component.

Your DAO and service objects need to be beans under Spring control. By instantiating them like this:
private ServiceFacade facade = new ServiceFacadeImpl();
Spring never gets to inject your dependencies and wire everything up, hence the NPE. Add the following to your XML file
<context:component-scan base-package="com.nutsaboutcandywebproject.dao"/>
<context:component-scan base-package="com.nutsaboutcandywebproject.service"/>
and make sure your DAO is marked with #Repository or #Component, and your services as #Service or #Component. And change the instantiation of facade to
#Autowired
private ServiceFacade facade;
Since there was no scan for the DAO package, you almost certainly have to do the same in ServiceFacadeImpl and its IProductsDataAccess field.
Update: Besides this, you're accessing beans which haven't been initialised yet, e.g.
private List<Product> productsList = facade.getAllProducts();
At that point in time, i.e. during object instantiation, Spring hasn't finished creating your DAOs, Hibernate session factory, etc. You can only access these beans and set your fields when Spring has finished initialising and injecting the dependencies. To do that, put the code in an initialisation method marked with #PostConstruct:
#Controller
public class ShoppingCartController {
#Autowired
private ServiceFacade facade;;
private NACExceptions exceptionsNAC = new NACExceptions();
private List<Product> productsList;
private List<Category> categoryList;
private List<ProductTypes> typeList;
private List<Sizes> sizeList;
private List<ProductPriceMatrix> priceMatrixList;
private List<String> exceptionList = new ArrayList<String>();
#PostConstruct
public void someInitializationMethod() {
productsList = facade.getAllProducts();
categoryList = facade.getCategory();
typeList = facade.getType();
sizeList = facade.getAllSizes();
priceMatrixList = facade.getProductPriceMatrices();
}
....

Add few more lines like this - in order to initiate the bean along with the datasource
<bean id="shoppingCartController" class="point.it.to.implementation.class">
<property name="mySessionFactory" ref="mySessionFactory"/>
</bean>
You can even try using #Autowired annotation, by simplying creating the setter method for it.
