Root Cause

** Two reasons for this issue were:**
This was happening because Hibernate was generating HT_Alien table which is a temporary table and the reason behind this was the Hibernate-core version 6.0.0.Alpha3.
I had no default constructor in the Alien(Entity) class
Suggestion:
Guys, please use hibernate core version 5.4.1.Final while using ORM using Hibernate. Below is the dependency for the same:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.4.1.Final</version>
</dependency>
The issue is resolved now!!

Could not autowire field jdbcTemplate - No qualifying bean of type

UPDATE
Adding code in GameDetailImageMapper
package spring;
import entities.GameDetailImage;
import java.sql.ResultSet;
import java.sql.SQLException;
import org.springframework.jdbc.core.RowMapper;
public class GameDetailImageMapper implements RowMapper
{
public GameDetailImage mapRow(ResultSet rs,int rowNum) throws SQLException
{
GameDetailImage gDetailImage = new GameDetailImage();
System.out.println("++++++++++++"+rs.toString());
gDetailImage.getGameDetail().setGameid( rs.getInt("game_id"));
gDetailImage.getGameDetail().setTitle( rs.getString("title"));
gDetailImage.getGameDetail().setDeveloper( rs.getString("developer"));
gDetailImage.getGameDetail().setPublisher( rs.getString("publisher"));
gDetailImage.getGameDetail().setGenre( rs.getString("genre"));
gDetailImage.getGameDetail().setPlatform( rs.getString("platform"));
gDetailImage.getGameDetail().setGameDescription( rs.getString("game_description"));
gDetailImage.getGameDetail().setDistribution( rs.getString("distribution"));
gDetailImage.getGameDetail().setReleaseDate( rs.getDate("release_date"));
gDetailImage.getGameDetail().setCreateDate( rs.getDate("create_date"));
gDetailImage.getGameDetail().setScore( rs.getInt("score"));
gDetailImage.getGameImage().setBanner_link( rs.getString("banner_link"));
gDetailImage.getGameImage().setBanner_title( rs.getString("banner_title"));
gDetailImage.getGameImage().setHero_link( rs.getString("hero_link"));
gDetailImage.getGameImage().setHero_title( rs.getString("hero_title"));
gDetailImage.getGameImage().setThumbnail_link( rs.getString("thumbnail_link"));
gDetailImage.getGameImage().setThumbnail_title( rs.getString("thumbnail_title"));
gDetailImage.getGameImage().setContent_image_link( rs.getString("content_image_link"));
gDetailImage.getGameImage().setContent_image_title( rs.getString("content_image_title"));
return gDetailImage;
}
}
Now that I have pointed my context config to the data.xml file I am getting the below exception. Not sure why this is happening as the query returns the correct data from my database. I am using a composite object in my mapper (two objects are included in the composite). Could that be what is causing the issue?

I am getting the following exception for my simple spring application. Think because I am not using spring injection correctly for the jdbcTemplate. I am using spring without Maven so no pom.xml. Running on Tomcat.

return this.jdbcTemplate.query("select * from GameDetail Inner Join GameImage on GameDetail.game_id = GameImage.game_id Order By GameDetail.create_date", new GameDetailImageMapper());

}

Thanks pointing the config file to my data.xml was the first step. The next step was that I wasn't using the mapper correctly. I added the getters and setters directly to the GameDetailImageMapper without using getGameDetail() and getGameImage().

I believe you configure the basePackage in MapperScannerConfigurer incorrectly. It should be package that containing the mapper class rather than the mapper class itself. So try to change the basePackage to:
<bean id="mapperSpeaker" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="ph.com.aub.mapper" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactorySpeaker" />
</bean>

Spring with Hibernate JPA - runtime errors

I'm trying to develop a simple web application using Spring and Hibernate JPA on Glassfish 4.1.1 server.
I have an entity class:
package entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "USERS")
public class User {
#Id
#GeneratedValue
#Column(name = "ID")
private long id;
private String firstName;
private String lastName;
private String email;
private String login;
private String password;
public User() {
}
public User(long id, String firstName, String lastName, String email, String login, String password) {
this.id = id;
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
this.login = login;
this.password = password;
}
getters and setters...
}
Then controller class:
package controller;
import ...
#Controller
public class LoginController {
#Autowired
private UserService userService;
#RequestMapping(value = "/login", method = RequestMethod.POST)
public ModelAndView executeLogin(HttpServletRequest request, HttpServletResponse response, #ModelAttribute("user") User user) {
userService.addUser(new User(20, "a", "b", "dgsd", "sfadf", "sdfsdf"));
}
}
UserService:
package service;
import dao.UserDao;
import entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
#Service
public class UserService {
#Autowired
UserDao userDao;
public void addUser(User user) {
userDao.insert(user);
}
}
UserDao:
package dao;
import entity.User;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.springframework.stereotype.Repository;
#Repository("userDao")

What am I doing wrong? Thanks for helping!

Your code attempts to create a JTA-capable entity-manager, because you configured your persistence unit to be JTA-enabled:
<persistence-unit name="LibraryPU" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:app/library</jta-data-source>
</persistence-unit>
But JTA-capable EMs are normally not to be created by webapps.
If you are really aiming for a simple webapp, you should most likely go for a simple persistence-unit. If you follow the link above (Chapter: Valid RESOURCE_LOCAL Unit usage) you will see what is the difference. A simple configuration could look like this for example:
<persistence>
<persistence-unit name="manager1" transaction-type="RESOURCE_LOCAL">
<class>org.hibernate.ejb.test.Cat</class>
<class>org.hibernate.ejb.test.Distributor</class>
<class>org.hibernate.ejb.test.Item</class>
<properties>
<property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
<property name="javax.persistence.jdbc.user" value="sa"/>
<property name="javax.persistence.jdbc.password" value=""/>
<property name="javax.persistence.jdbc.url" value="jdbc:hsqldb:."/>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/
<property name="hibernate.max_fetch_depth" value="3"/>
<!-- cache configuration -->
<property name="hibernate.ejb.classcache.org.hibernate.ejb.test.Item" value="read-write"/>
<property name="hibernate.ejb.collectioncache.org.hibernate.ejb.test.Item.distributors" value="read-write, RegionName"/>
<!-- alternatively to <class> and <property> declarations, you can use a regular hibernate.cfg.xml file -->
<!-- property name="hibernate.ejb.cfgfile" value="/org/hibernate/ejb/test/hibernate.cfg.xml"/ -->
</properties>
</persistence-unit>
</persistence>
