how to update, delete an object from Sql database using Hibernate?

Description
i simply want to implement ORM using Hibernate with mysql but the only
methods that are working are adding a single object to the database, returning
a list of objects, returning a list of objects by a keyword but deleting an
object and updating an object are not functioning!
any suggestion?
the table is created in the database with no problem :)

UnsatisfiedDependencyException Spring MVC project context root issue

edit: added #Repository and #Service to UserDAOImpl and UserServiceImpl classes as per user7294900 and #skhussain suggestions, however I'm still getting a similar stack trace (updated with below)
I'm creating a web app with Spring MVC using Hibernate, REST and Maven. I can reach my index.jsp page fine, however trying to reach my REST mapping gives me the following stack trace:

I've had a similar issue like this before with a Spring MVC project and it required updating my dependencies within pom.xml. However I feel I've gone through the dependencies and code a million times without any luck!

Additionally the context root always defaults to 'spring-crm-rest' even if I change it to 'remixapp' within Properties -> Web Project Settings..? I'm not sure why - 'spring-crm-rest' was a previous project but this string is declared absolutely nowhere in my code.
With that in mind, I can reach 'http://localhost:8080/spring-crm-rest/ without any issues (which points to index.jsp). However requesting 'http://localhost:8080/spring-crm-rest/api/users' gives me the above stacktrace.
In fact, entering anything after the root context path gives me the same error, e.g. 'http://localhost:8080/spring-crm-rest/fghfg'
I had confirmed my app could connect to the MySQL database, however that was through a basic servlet which wasn't reading from my pom.xml.
I've also tried clearing cache from Tomcat, cleaning my project, deleting dependencies from my local maven repo, updating project's maven dependencies -> in-case there's some cache issue.

Add #Service annotation to UserServiceImpl so it'll be known to Spring as a Service class
#Service("userService")
public class UserServiceImpl implements UserService {
Indicates that an annotated class is a "Service"
Also add #Repository to UserDAOImpl follow #skhussain comment
#Repository("userDAO")
public class UserDAOImpl implements UserDAO {

OK I figured it out! It seems this dependency is conflicting with other Hibernate packages:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.5.6-Final</version>
</dependency>
After removing it + adding the suggestions from #user7294900 and #sk hussain I've fixed the issue :)

SpringBoot JPA Hibernate: Error creating bean with name 'entityManagerFactory'

I am trying to setup a Spring Boot application, which uses SpringBoot Security to authenticate users, which are stored in my MySQL database.
I have followed some tutorials on how to make this, however, when i try to run the application with maven i get the following error:

If I am not mistaken, this means that I cannot connect to my database, therefore I have problem creating bean entityManagerFactory

I have the following DAOs:
RoleDAO.java
package com.proba.Userboard.dao;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.proba.Userboard.entity.Role;

import org.springframework.transaction.annotation.Transactional;
import com.proba.Userboard.entity.User;
#Repository
#Transactional
public interface UserDAO extends JpaRepository<User, Integer> {
public User findByUsername(String username);
}
My User Service:
package com.proba.Userboard.service;
import java.util.HashSet;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import com.proba.Userboard.dao.RoleDAO;

import com.proba.Userboard.entity.User;
public class UserServiceImpl implements UserService {
#Autowired
private UserDAO userDAO;
#Autowired
private RoleDAO roleDAO;
#Autowired
private BCryptPasswordEncoder bcrypt;
#Override
public void save(User user) {
user.setPass(bcrypt.encode(user.getPass()));
user.setRoles(new HashSet<>(roleDAO.findAll()));
userDAO.save(user);
}
#Override
public User findByUsername(String username) {
return userDAO.findByUsername(username);
}
}
My SpringBoot Security configuration:
package com.proba.Userboard.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
#Configuration
#EnableWebSecurity
public class SecurityConf extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService userDetailsService;
#Bean
public BCryptPasswordEncoder bcyrpt() {
return new BCryptPasswordEncoder();
}
#Override
protected void configure(HttpSecurity http) throws Exception {

}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {

}
}
So, when i run mvn clean spring-boot:run, I get previously mentioned error and I cannot figure out what I am doing wrong. Previously I made similiar app, which worked, but I cannot figure out, why this one doesn't.

No, the problem is not in the connection of the database. Hibernate determines its policy to check the configuration annotations based on the annotation place on the id (on the attribute itself or on a method).
In your User class, you are telling hibernate to expect the annotations on the attribute level.
public class User {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="user_id")
private int id;
So for hibernate you do not have a mapping for other attribute like roles because it will not check the methods for the mapping, so what you need to do is to take the annotation from the method and put it in the attribute.
#ManyToMany
#JoinTable(name="user_role", joinColumns = #JoinColumn(name="user_id"), inverseJoinColumns = #JoinColumn(name="role_id"))
private Set<Role> roles;
You need to do this in all your annotations.

If there is a mapping exception along with above mentioned exception, the problem can be with Jdk 11 and javassist.
Need to add this in pom.xml
<dependency>

Error creating bean with name 'clientsDaoImpl': Injection of autowired dependencies failed;

This error is killing me, i searched a lot of similar topics here, but none of them helped me!
So, i'm using spring MVC+hibernate. Please, just take a look, maybe you will find mistake which i missed!

Possibly try this solution from here: Getting a org.springframework.beans.factory.BeanCreationException with my first Maven, Spring Project
just add:

I think your missing the repository name in your ClientsDaoImpl .
#Repository("clientsDAO")
public class ClientsDaoImpl implements ClientsDao.....

Entity class cannot be cast to java.lang.Number

This issue is a continuation of this problem: Foreign key as a part of composite primary key and ManyToOne relationship in OpenJPA
OpenJPA is tring to cast my entity class (TableB) to type of its key (long). Why?
Persisting of TableB object without any elements in field rows works fine. The problem begins when 'm adding elements to rows.
TableA.class:
package org.model;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.IdClass;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
#Entity
#IdClass(TableA_PK.class)
public class TableA implements Serializable {
#Id
private int fId;
#Id
private String item;
#Id
private String release;

#ManyToOne
#JoinColumn(name = "b_id")
private TableB tableB;
#Column
private String field1;
#Column
private String field2;
public TableA() {
}
public int getfId() {
return fId;
}
public void setfId(int fId) {
this.fId = fId;
}
public String getItem() {
return item;
}
public void setItem(String item) {
this.item = item;
}
public String getRelease() {
return release;
}
public void setRelease(String release) {
this.release = release;
}
public TableB getTableB() {
return tableB;
}
public void setTableB(TableB tableB) {
this.tableB = tableB;
}
public String getField1() {
return field1;
}
public void setField1(String field1) {
this.field1 = field1;
}
public String getField2() {
return field2;
}
public void setField2(String field2) {
this.field2 = field2;
}
}
