Spring hibernate upgrade Autowiring is causing classnotfound exception on org/hibernate/cfg/Configuration

Below is my spring and hibernate versions
spring.framework.version - 4.0.2.RELEASE
hibernate.version5.0.10.Final
Java 8
Am getting the below exception while trying to deploy the code on Tomcat 7. While getting into the last method called. Its coming from the autowiring class thats internally trying to access org.hibernate.cfg.Configuration and its not able to find it.
Is there a possibility the version of Spring and Hibernate are not compatible ?
But my other projects are using the above combination without autowiring and it works just fine.

How to upgrade ALL the spring dependency?

I have a spring-webmvc based web application. It used the org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer which is not supported by the spring version used in my project.
My project's spring dependency look like this:
I want to upgrade all spring dependency from 3.1.1 to 4.1.2. How to do that?

You should move from a hardcoded version of a spring version inside a pom.xml to a property, e.g.
inside your properties
<springframework.version>4.0.2.RELEASE</springframework.version>
inside your dependencies
<!-- spring -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${springframework.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-expression</artifactId>
<version>${springframework.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${springframework.version}</version>
</dependency>
<dependency>

<artifactId>spring-context-support</artifactId>
<version>${springframework.version}</version>
</dependency>

<artifactId>spring-orm</artifactId>
<version>${springframework.version}</version>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${springframework.version}</version>
</dependency>
<!-- spring security -->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>${springframework.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>${springframework.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>${springframework.security.version}</version>
</dependency>
with this setup its easy to migrate the versions, the listed deps are just copy/paste, don't take it for granted, use what you need

you can update dependency like this globally :
<properties>
<spring.version>4.1.2.RELEASE</spring.version>
</properties>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
using this global dependency version management, you can avoid some version compatibility exception.

Since you are using Maven, your pom-dependencies will probably look like
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
...
You could replace "3.1.1.RELEASE" with ${spring-version}, and add the following to your pom-file
<properties>
<spring-version>4.1.2</spring-version>
</properties>
It will make it easier to change version for all your spring dependencies

If you using maven build tool,so it's very simple to upgrade spring 3 to spring 4 you just open pom.xml file in the properties xml tag just change the version 3.x.x to 4 something. e.g:
<org.springframework-version>3.0.2.RELEASE</org.springframework-version>
to
<org.springframework-version>4.0.2.RELEASE</org.springframework-version>

What dependency do I need to use AmqpAppender for log4j?

In my log4j.properties I have the following line:
log4j.appender.queue=org.springframework.amqp.log4j.AmqpAppender
In my pom.xml I have the following spring related inclusions:
<!-- Spring dependencies -->

<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>1.2.0.RELEASE</version>
</dependency>
When I startup the application, I see the following exception:
log4j:ERROR Could not instantiate class [org.springframework.amqp.log4j.AmqpAppender].
java.lang.ClassNotFoundException: org.springframework.amqp.log4j.AmqpAppender
...
What dependency do I require to make use of org.springframework.amqp.log4j.AmqpAppender ?

You have correct dependency, but class is different a bit:
org.springframework.amqp.rabbit.log4j.AmqpAppender
Pay attention to the package, please.

Not sure I think the appender you found is a different one. There is one appender in:
<dependency>
    <groupId>org.springframework.amqp</groupId>
    <artifactId>spring-amqp</artifactId>
    <version>1.3.6.RELEASE</version>
</dependency>
from spring-ampq.
The spring version maybe different too.

Can I use new spring 3.2 with older spring-security 3.0

I want to upgrade Spring framework from 3.0 to 3.2, but would like to skip upgrading spring-security for a while.
Can I use new spring 3.2 with older spring-security 3.0 ?
Spring modules used are spring-core, spring-orm, spring-mvc (for web services only)

We are successfully running an application based on Spring 3.2.1.RELEASE and Spring Security 3.1.3.RELEASE. We didn't have any particular problem while setting this up.
Unfortunately I don't have any source that show this is officially supported.
If you are using Maven in your project, you should force versions to avoid having the same jars with multiple versions in your classpath:
<properties>
<spring.version>3.2.1.RELEASE</spring.version>
<spring-security.version>3.1.3.RELEASE</spring-security.version>
</properties>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>${spring-security.version}</version>
</dependency>
<!-- Etc. (specify a fixed version for each Spring jar) -->
</dependencies>
</dependencyManagement>

I am running slightly different combination - Spring 3.1.4 with Spring Security 3.0.5 and it also works fine:
<properties>
<spring.version>3.1.4.RELEASE</spring.version>
<spring.security.version>3.0.5.RELEASE</spring.security.version>
</properties>
