Resolve ServiceConfigurationError when adding Togglz to Spring Boot application

I'm trying to implement Togglz in my Spring Boot application.
I followed the Quick Start steps but when I run my application I get this exception:
Exception in thread "main" java.util.ServiceConfigurationError: org.togglz.core.spi.BeanFinder: org.togglz.cdi.spi.CDIBeanFinder Unable to get public no-arg constructor

This is my code in TogglzTest:
if(MyFeatures.FEATURE_ONE.isActive() ) {
System.out.println("togglzOff is " + togOnTrue);
System.out.println("togglzOff is " + togOnFalse);
}
Here is my isActive method in MyFeatures:
public boolean isActive() {
return FeatureContext.getFeatureManager().isActive(this);
}
I did some Googling and all I can find was various dependencies that I should add but doing so doesn't resolve my issue. Here's my pom:

How do I resolve this?

How to solve “Failed to instantiate WebApplicationInitializer class”

I found a good example for generating odata from MySQL at this GitHub repository
I can run the project by using the command mvn spring-boot:run -P jar inside the eclipse. The only part that I changed in comparison to the original code is my connection details to my local MySQL inside the application.properties file:
# WEB SERVER
server.port=9090
# MYSQL DATA SOURCE
spring.datasource.url = jdbc:mysql://localhost:3306/olingo
spring.datasource.username = admin
spring.datasource.password = 123456
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
# HANA (CLOUD) DB
#spring.datasource.jndi-name = java:comp/env/jdbc/DefaultDB
#spring.jpa.hibernate.ddl-auto = update
#spring.datasource.testWhileIdle = true
#spring.datasource.validationQuery = SELECT 1
# HSQL DB
#spring.datasource.platform=hsqldb
# JPA / HIBERNATE
spring.jpa.show-sql = false
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
# AZURE
#logging.path = D://home//LogFiles

I can build the project with mvn clean install but when I deploy the war file inside the Tomcat it cannot run the app. It seems the same issue is the source of the problem!
Any help for solving this issue is appreciated.

I think you didn't let spring know about some bean class.
Look at your xml or configuration file for LoggerFactory
In the exception stack above,
it says java.lang.ClassNotFoundException occured.
Spring can't find class files even if you have them in your java src package.
If my answer doesn't solve your problem,
you need to show your xml or source code to make sure what the problem is.

I changed the pom.xml and removed the profiles, then I could build the project with mvn clean install which will result a war file that I can deploy in Tomcat.

However when I deploy it in the Tomcat it can access the database for some hours and after some hours it cannot anymore fetch data from MySQL!
When we want to run the app inside the Eclipse with Run on Server option, it needs to access the app after a success run like this http://localhost:9090/<artifactName>/ i.e. http://localhost:9090/odata/ in this case!

404 Not found Spring boot war to Tomcat

I have Spring boot applicatio. This works fine with embedded server. And i can use Postman to test API.
Now i want deploy this on Tomcat 8 i create root.war file with maven install
and put it to Tomcat/webapps/
I run tomcat without any errors. But when i use the same url as postman it gives me 404 not found.
Example of url i use for both(embedded and tomcat): localhost:8080/auth/registration
I've tried to set server.context-path in application.properties but no result.
I believe that problem is in configuration of project.
Here is my pom.xml

EDITED
Also i have found that spring boot can be compiled to JAR as better way than war. If it's better how to change pom.xml for compiling in jar.
So i've tried to create jar as suggested below. I run this with java -jar and got
org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatEmbeddedServletContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.HttpEncodingAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.http.encoding-org.springframework.boot.autoconfigure.web.HttpEncodingProperties': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: javax/xml/bind/ValidationException

Step1:
Add/Update the following dependency to pom.xml (scope as provided) in order to tell Spring Boot not to use its embedded Tomcat.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
Step2:
<properties>
<packaging>war</packaging>
</properties>
Step3:
SpringBootApplication class should look like below:
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
Reference: Create deployable-war-file and Maven Packaging

add these in pom.xml
<modelVersion>4.0.0</modelVersion>
<groupId>com.muna.manas</groupId>
<artifactId>core-java</artifactId>
<version>0.1.0-SNAPSHOT</version>
<packaging>jar</packaging>
The most important aspect here is the type – to create an executable jar, double check the configuration uses a jar type.

Migrated Spring boot 1.5 to 2.0, unable to start app getting: java.lang.ClassNotFoundException: org.springframework.boot.bind.RelaxedPropertyResolver

I upgraded my existing working Spring Boot application, from springboot 1.5 to 2.0.
Now, I am getting below error message, when I try to deploy the application.
Please help.
Note: I don't have #ComponentScan, instead I am using #SpringBootApplication at root package in my application. Also, I am using the latest version of apache camel springboot dependencies.
Also, if I remove the below dependency, the application deploys fine, but ofcourse, without Apache Camel router initialized!
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-spring-boot-starter</artifactId>
<version>2.20.2</version>
</dependency>
How I did update: Changed the springboot version in pom.xml

Got this resolved.The Apache Camel 2.20.2 is supported for spring boot 1.5 only. As per Apache Camel website, they will extend support to spring boot starting with 2.22 (early summers 2018). So to resolve, just need to use spring boot 1.5.10 only for now. Thanks all for checking / responding.
Reference Links: http://camel.apache.org/camel-2210-release.html
"This release supports only Spring Boot 1.5.x. Support for Spring Boot 2.0.x is coming in Camel version 2.22 which is planned for early summer 2018."
P.S. At http://start.spring.io/ (Switch to the full version) you can check if a Spring Project(Apache Camel) is compatible with your Spring Boot version. Currently the Initilizer shows
Apache Camel
Integration using Apache Camel
requires Spring Boot >=1.4.0.RELEASE and <2.0.0.M1

Spark runtime error: spark.metrics.sink.MetricsServlet cannot be instantialized

I got invocation target exception when running project with spark 1.3 lib in maven in IntelliJ.
I got met this error only in IntelliJ IDE. After I deployed the jar and ran via spark-submit, the error went out.
Any one has met with the same problem before? I hope to fix this problem so as to do easy-debugging. otherwise I have to package the jar every time when I want to run the code.
details are as below:

Strangely, I found the error didn't come out any more when I move the spark related dependencies to the front.
<dependencies>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.10</artifactId>
<version>1.3.0</version>

<groupId>org.apache.spark</groupId>
<artifactId>spark-mllib_2.10</artifactId>
<version>1.3.0</version>
</dependency>
//....the rest dependencies....
</dependencies>
So the sequence of the dependencies matters! Any one knows why?

I think the issue here is in jackson dependency. I had similar issue and problem was multiple jackson-core and jackson-databind versions. I think it is scala related issue. Anyway add this 2 jackson dependencies to pom with lower versions and it should work. Maybe you will not find right version from first try. This one works for me.
<jackson-core.version>2.4.4</jackson-core.version>
<spark.version>2.3.0</spark.version>

Jackson dependency issue - I had spark3.0.3-hadoop2.7 version, and had 2 versions of jackson annotation and databind jars. Removed those, and this error got solved.
