I am trying to make one project on spring and hibernate. I did half part of front end but when I tried to connect it to the hibernate and make changes in my pom.xml file it is giving me error while restarting the tomcat server. Please help. Thanks in advance.

If you are not familiar with Spring and Hibernate it is much easier to create Spring Boot project:
https://start.spring.io/
or if you use IntelliJ IDEA:
File -> New -> Project -> Spring Initializr
Delete and repopulate maven's cache of artifacts,
as explained in duplicate question hibernate-commons-annotations-4.0.1.Final.jar; invalid LOC header (bad signature)?

Your spring dependencies version are a mess, you should have the same version in all modules. otherwise if those version are a requirements you have to check which version is compatible with the other
I am working on spring boot application when running this from console I am getting the below error. Please help me in resolving this. In IDE I am not able to see exception also only command line generating this stack trace. Tried working with different java update (8u121,8u131,8u144) .

Also please look into above POM xml and update me if I am missing any dependencies. Same code is working fine on other machine
Please try with this pom.xml in order to use the 1.5.4.RELEASE version of Spring boot and the current version of h2 database, make sure that all the dependencies are downloaded before restart your application, if you are using eclipse also make sure to update the maven repository to the project. Hope it help. There are many dependencies so it takes time in order to download all of them properly. The parent entry should looks like this:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.4.RELEASE</version>
</parent>
Some additional information here: in order to make the SpringBootCRUDApp project ready to work you can use 1.4.x or 1.5.x Spring boot releases, just make sure that all the dependencies have been downloaded properly from Maven otherwise the java.lang.NoClassDefFoundError will be thrown.
After all the dependencies are properly downloaded there is something interesting that happens with Spring boot 1.4.x because there is a new error when the code is executed called java.lang.IllegalStateException: required key [datasource.sampleapp.hibernate.dialect] not found
Why is that?: it is because of how are listed the available profiles on the application.yml properties file.
spring:
profiles: local, default
The error is raised because the blank space after the coma, in order to correct it just delete the blank space (only when Spring Boot 1.4.x is used)
spring:
profiles: local,default
and it happens because the value
" default" is not detected as a defult profile because Spring boot is expecting a "default" with out the blank space, this behavior only happens with SB 1.4.x
Why in Spring boot 1.5x there is no error? well it is because of some good enhancements that has been made to the configuration process in order to read properly the spring.profiles property and avoid the problem when there is a blank space after coma, actually that could happen only when there are many profiles but no one is active and also there is no a default profile detected.
I have created a controller service to connect to a test db.
I have a custom processor that reads data from SQL Server, the mock tests, the build and the deployment to NiFi succeed. The processor runs into error, maybe the nar dependency scope is at fault or ... ?
I am unsure The pom for processor and the nar projects are as follows :

In the controller service, I do not see my custom processor in
'Referencing Components'(it says 'no referencing components')
Right now, I have hard-coded the 'Database Driver Location(s)' but in
production, I would like the controller to pick up that from the
classpath(somehow, is it possible?)
*****Edit-1*****
As suggested by Mahendra, I did the following :
Without any changes to the existing pom.xml files, added the dependency (sqljdbc4, 4.0) to both, the build and deployment succeeded but the jdbc driver error persisted
The 'Database Driver Location(s)' kept as 'file:///'. Same error
Added the sqljdbc4.jar in NiFi/lib and the driver error vanished(getting other errors but those will be taken in a different thread). Note that the controller service still doesn't show the processor as 'referenced component'.
The java version
java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
Isn't there a way to avoid adding the sqljdbc4.jar in lib, I mean third-party dependencies like fasterxml etc. are behaving properly, is this an issue with my configuration or some problem with the sql server maven repos. ?
#kaliyug,
EDIT 1:
1.if you declared DB class name is "com.microsoft.sqlserver.jdbc.SQLServerDriver".You should add below maven dependency in pom like below.,
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.2</version>
</dependency>
Or If you want's to use in production environment you can specify driver database location in controller service like below.
file:///C:\DBLocation\sqljdbc42.jar
3.Or you can just copy the "sqljdbc42.jar" directly into NiFi\Lib directory.After copied the jar,you should restart NiFi Services.At runtime ,SQL jar automatically Loaded when it search for DB ClassName in Nifi\Lib directory.
Please let me know if you have face any issues.
I am building a system using Spring Boot. I am using Spring Tools Suite as the IDE, and I can build and run the program as Spring Boot App using Spring Tool Suite without any problems. However, when I build via maven via command "mvn package", and run the generated jar file under target/my-app.jar, the embeded tomcat failed to start. The error is like below:

Any suggestions will be greatly appreciated!
I have figured this out. My system is to interact with a third party enterprise system, and my system depends on some JAR files from third party system. So I have the "-Dloader.path" points to the directory of the third party JAR files. One of the JAR files, j2ee.jar, conflicts with tomcat. Tomcat will start if I remove j2ee.jar file from the "-Dloader.path".
Anyway, thank you again for all of your suggestions!
As Deinum suggested in the comments.
Your jar does not have the embedded tomcat dependency included in it, since you have provided the tomcat dependency scope as "runtime". Remove the scope declaration which should enable the "compile" scope by default. Your jar should then contain the dependencies required for starting the embedded tomcat container.
I am new to swagger, i had to write swagger for a given POJO (just POJO) and implement API for it. So by using swagger editor I was able to write swagger processed with no errors and then did
1. Generate Server from menu and selected spring
2. Generate Client from menu and selected client
I opened the generated java API client and build successfully.
I opened the generated spring server in IntelliJ and try to run the server and I got below error ...

I try to generate spring server for the examples default, heroku, instagram, twitter they have provided and for these also getting same error.
I think the issue is the provided scope for tomcat. This would assume that you are deploying the app into an existing tomcat instance. Can you try removing that scope, refresh the project, and try running again?
