Not able to set session factory through servlet.xml using Spring MVC and Hibernate 5

I want to set session factory in DAO class but after execution I got this issue. In my class i am setting sessionFactory variable through #Autowired annotation but it is not able to set the session Factory.
***************************
APPLICATION FAILED TO START
***************************
Description:
Field sessionFactory in com.springboot.webcrud.dao.ClienteDao required a bean of type 'org.hibernate.SessionFactory' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'org.hibernate.SessionFactory' in your configuration.
Process finished with exit code 1
WHEN I REMOVE THE #Autowired ANNOTATION THEN THE SESSION FACTORY IS ALWAYS NULL WHEN I TRY TO GET THE CURRENT SESSION

Entity Manager is null when trying to connect to Dockerised DB2 in Java using JPA, also using maven & Open Liberty

So I'm developing an API and I'm trying to connect to a local docker instance of DB2 from java using JPA entity manager. After running Apache Maven and getting build success, I try a GET request from Postman to test an endpoint and get a list of all users from DB2. I'm receiving the below error saying that entity manager is null. I've tried researching online and can't seem to find the solution.
The Dao class is virtually unchanged from a previous iteration that used Derby instead of DB2 and it worked fine.
I was wanting to know where I've gone wrong, what needs changing, and if anything is not needed. Provided below is the xml files and the DAO java class containing the entity manager. All properties for DB2 is correct as they're unchanged from a successful connection I was able to do from Eclipse's Database Development. The driver used then was db2jcc4 which I think is different to the driver said to use for the maven dependency so not sure if that's an issue.
Postman:
Error 500: java.lang.NullPointerException: Cannot invoke
"javax.persistence.EntityManager.createNamedQuery(String, java.lang.Class)" because
"this.em" is null
Maven:

Your persistence.xml is incorrect. It should point to datasource configured in the server.xml, not specify driver properties.
Like this:

You can check this very simple Liberty project which uses JPA and database here https://github.com/stocktrader-ops/db-sat-demo (it is using PostgreSQL instead of DB2, but you should just use your datasource setup)

#Autowired does not inject Spring Data JPA Repository - NullPointerException

I'm doing a GWTP project and use Spring Data JPA for a connection with an oracle database. I've read several tutorials in which a repository interface is used directly without the use of implementation. It was #Autowired where needed and it worked fine. I've tried to use the same strategy but it seems the #Autowired annotation is not working at all.
Here is my Repository :
#Repository
public interface BugRepository extends JpaRepository<Bug, Long> {
List<Bug> findAll();
.....
}
I try to inject it with #Autowired in my service implementation (I use RESTful services) :
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
#Path("/bugs")
#Component
public class BugServiceImpl{
#Autowired
private BugRepository bugRepository;
#GET
#Path("/findAll")
public List<Bug> findAll() {
return bugRepository.findAll();
}
}
Here is my Entity :
#Entity
#Table(name = "BUGS")
#SequenceGenerator(name = "BUG_SEQUENCE", sequenceName = "BUG_SEQUENCE")
public class Bug implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "BUG_SEQUENCE")
#Column(name="BUG_ID")
private Long bugId;
#Column(name="BUG_NAME")
private String bugName;
#OneToOne
#PrimaryKeyJoinColumn
#Column(name="CREATED_BY")
private User createdBy;
#OneToOne
#PrimaryKeyJoinColumn
#Column(name="ASSIGNED_TO")
private User assignedTo;
#Column(name="CREATION_DATE")
private Date creationDate;
#Column(name="LAST_UPDATE_DATE")
private Date lastUpdateDate;
#Column(name="BUG_COMMENT")
private String bugComment;
#OneToOne(cascade = CascadeType.ALL, optional = false, fetch = FetchType.EAGER, orphanRemoval = true)
#PrimaryKeyJoinColumn
#Column(name="PRIORITY_ID")
private Priority priority;
#OneToOne
#PrimaryKeyJoinColumn
private Status status;
public Bug() {
}
}

When I debug the code and put a breakpoint to the autowired repository it appears to be null so I suppose it's not injected properly and that's why invoking the method findAll fires the NullPointerException. So, why do you think the #Autowired annotation is not working?

I think you're mixing two ways of Spring/JPA configuration. Last time when i configured Spring/JPA project with XML I use only DataSource bean without persistence.xml configuration for connection to the database. I can suggest you to read the official documentation of Spring Data. The community has one of the best documentation.
http://docs.spring.io/spring/docs/current/spring-framework-reference/html/orm.html

First problem that i see is you have annotated your interface with #Repository
You shouldn't do that, but as follows:
//no annotation here
public interface BugRepository extends JpaRepository<Bug, Long> {
List<Bug> findAll();
.....
}
Secondly, make sure your BugRepository interface is in the package below, or else it wont work:
<jpa:repositories base-package="com.edu.server.repositories" />
Third thing i noticed is in your persistance.xml, you have noted NOT only #Entity beans, but #Service and a #Repository. You are supposed to only have #Entity beans (which are to be managed)
Lastly, you seem to be mixing Spring and Jersey, so make sure you have your Spring container (application/web context) properly set up, so it can manage (inject) your beans/repos/services.

I want to thank all for the help. I solved my problem. There were problems in my configuration files.
First of all, I really didn't need any persistence.xml because I've created a dataSource bean in my applicationContext.xml which contains all of the needed information regarding the connection with my database. You shouldn't mix the both things, I suppose.
Secondly, you should properly configure the link between Spring and Jersey. I had to add some new dependencies in my pom.xml which were needed for linking Spring and Jersey (there is a jersey-spring3 dependency which I didn't know existed). So, now all of the dependencies I use, concerning Spring and Jersey are these:

In addition, I had to configure my web.xml so that Jersey could read the applicationContext.xml. Without configuring my web.xml the applicationContext.xml was useless and that's why the annotations and the connection with the database didn't work. Here is my web.xml :
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</servlet>
<servlet-mapping>
<servlet-name>jersey-serlvet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
As far as I understood the ContextLoadListener makes sure the web configuration "listens" for other configuration xml files and that's how the applicationContext.xml is now read and used. And with these settings
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.edu</param-value>
I make sure that my packages would be scanned for #Provider and #Path annotations and without these piece of my code my services would not be active.
More about this Provider Packages setting can be read here :
https://jersey.java.net/apidocs/2.23.2/jersey/org/glassfish/jersey/server/ServerProperties.html#PROVIDER_PACKAGES
I hope my issue and this answer are useful for all with similar configuration problems.

load external config file in spring batch admin

I downloaded the spring batch admin application in the github repo and I imported it in eclipse. it works perfectly.
Then, I asked myself how to import an external config file into the application that I can use in my job definition class.
I tried this :
VM Arguments
-Dspring.config.location=C:/path/to/config/file/application.properties
Job configuration
src/main/java

#Configuration
public class JobConfiguration {
//I try to import this properties from an external config file.
#Value("${folder.input.files}")
private String pathToFiles;
#Autowired
public JobBuilderFactory jobBuilderFactory;
#Autowired
public StepBuilderFactory stepBuilderFactory;
#Bean
#JobScope
public ExampleItemReader itemReader() {
return new ExampleItemReader();
}
#Bean
#StepScope
public ExampleItemWriter itemWriter(#Value("#{jobParameters[fail]}") Boolean fail) {
ExampleItemWriter itemWriter = new ExampleItemWriter();
itemWriter.setFail(fail);
return itemWriter;
}
#Bean
public Step step1() {
return stepBuilderFactory.get("step1")
.<String, Object>chunk(5)
.reader(itemReader())
.writer(itemWriter(null))
.build();
}
#Bean
public Job javaJob() {
return jobBuilderFactory.get("javaJob")
.start(step1())
.build();

I tried this post and much more but without success.
I use exactly the same files and the same configuration than the spring batch admin github project.
Can someone tell me how to add the external configuration file to spring batch admin?

Spring batch admin searches configurations in specific paths.This page explains from which paths it loads resources:
<import resource="classpath*:/META-INF/spring/batch/bootstrap/**/*.xml"/>
<import resource="classpath*:/META-INF/spring/batch/override/**/*.xml"/>
Note that the "override" location has no files in it in Spring Batch
Admin distribution. This is a placeholder for users to add their own
content.
We managed to load external properties files placing xml configuration file under src/main/resources/META-INF/spring/batch/override/manager/env-context.xml which looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- Use this to set additional properties on beans at run time -->
<bean id="placeholderProperties"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:/org/springframework/batch/admin/bootstrap/batch.properties</value>
<value>classpath:batch-default.properties</value>
<value>classpath:batch-${ENVIRONMENT:hsql}.properties</value>
<value>classpath:batch-${ENVIRONMENT:mysql}.properties</value>
<!-- here we load properties from external config folder -->
<value>file:${spring.file.location}</value>
</list>
</property>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="ignoreResourceNotFound" value="false" />
<property name="ignoreUnresolvablePlaceholders" value="false" />
<property name="order" value="1" />
</bean>
</beans>

Under main folder of spring-batch-admin template, there are three folders - java, resources and webapp. Under resources there are some property files and META-INF folder. within META-INF there are two folders - batch and servlet.
Here If I want to add new property file "batch.properties" under resources and want to refer the property values from configuration (xml) files from "META-INF/batch/*.xml" in addition to the properties from spring-batch-admin-manager-1.0.0.M1.jar,
1. where to add below entries
Where to keep "env-context.xml". Under which folders, coz in "src/main/resources/META-INF" i can see only one folder batch.
I tried to create "spring/batch/override/manager/env-context.xml" under "src/main/resources/META-INF" but not able to read the property file entries.
If you provide your working application folder structure will help me a lot.

You can put your env-context.xml file on spring/batch/servlet/override/env-context.xml folder.

Thanks in advance...

The problem is in the place where you are injecting EventDaoImpl.
Just replace
#Autowired EventDaoImpl eventDaoImpl
with
#Autowired EventDao eventDao
wherever you need Spring to autowire the dao.
Or if you are getting the bean from the applicationContext use:
EvntDAO evntDAO = (EvntDAO) context.getBean("evntDAO");
The problem is caused by the fact that the use of #Transactional annotation on the dao's implementation code means that Spring will create a JDK dynamic proxy for it, which cannot be cast to the implementation class. Here is the complete documentation of Spring's AOP capabilities (where the creation of JDK dynamic proxies and CGLib class proxies is fully explained).
What that essentially means is that because of #Transactional, when you call context.getBean("evntDAO") you don't get back your EventDaoImpl (as one would expect), but you actually get back an object whose class is java.lang.reflect.Proxy which has been created by Spring. That proxy object implements EventDao (and therefor can be cast to it) but it's signature has nothing to do with EventDaoImpl (and hence the ClassCastException since it does not extend EventDaoImpl). When a method is called on the proxy various things happen before and/or after the call is actually delegated to EventDaoImpl (what happens before/and or after the actual call to EventDaoImpl is controlled by Spring though the implementation of InvocationHandler).
