Replacing tomcat with undertow server for spring-boot-keycloak project results in IllegalStateException: No ServletContext set

I'm trying to setup a simple spring-boot example project (keycloak tutorial) but I'm stuck at a startup error. The only thing that differs from the original config is that I want to use an undertow server instead of tomcat.
Running the main class without any changes is successfull (main class annotated with #SpringBootApplication) (mvn spring-boot:run after clean & install) (standard tomcat setup).
After the following changes in the pom, I'm getting an error:
java.lang.IllegalStateException: No ServletContext set
See below for details:

Spring-boot.version used is 2.3.3.RELEASE (as stated in a parent pom).
How can i get this to work with an undertow server?

fixed
When the part as shown below is detached from the original SecurityConfig class, it works with undertow:
(new class)
#Configuration
public class KeycloakConfig {
#Bean
public KeycloakSpringBootConfigResolver KeycloakConfigResolver() {
return new KeycloakSpringBootConfigResolver();
}
}

How do I add Spock to my Springboot project?

I'm trying to add Spock framework to my spring boot project, but I can make it work. I added those dependencies:
<!-- https://mvnrepository.com/artifact/org.spockframework/spock-core -->
<!-- https://mvnrepository.com/artifact/org.spockframework/spock-core -->
<dependency>
<groupId>org.spockframework</groupId>
<artifactId>spock-core</artifactId>
<version>1.2-groovy-2.5</version>
<scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.spockframework/spock-spring -->
<dependency>
<groupId>org.spockframework</groupId>
<artifactId>spock-spring</artifactId>
<version>1.2-groovy-2.5</version>
<scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.codehaus.gmavenplus/gmavenplus-plugin -->
<dependency>
<groupId>org.codehaus.gmavenplus</groupId>
<artifactId>gmavenplus-plugin</artifactId>
<version>1.6</version>
</dependency>
And then I created this test:
#SpringBootTest(classes = EdoobyApiApplication.class)
class AddressServiceSpockTest extends Specification {
def "when context is loaded then all expected beans are created"() {
expect:
1 + 1 == 3
}
}
This is what I have on my EdoobyApiApplication.java
#SpringBootApplication
#EntityScan(basePackageClasses = {
EdoobyApiApplication.class,
Jsr310JpaConverters.class
})
public class EdoobyApiApplication {
#PostConstruct
void init() {
TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
}
public static void main(String[] args) {
SpringApplication.run(EdoobyApiApplication.class, args);
}
#Bean
public ObjectMapper getObjectMapper(){
return new ObjectMapper();
}
}
When I try to run the test I get this error:

I'm not familiar with Spock, so I'm not sure if there is any other dependency I should add or any other configuration. Also I'm not sure I should be adding EdoobyApiApplication at the #SpringBootTest. If someone could give me a direction to look for would be great.
Thanks!

This isn't a Spock or Spring problem.
Java will throw a NoSuchMethodError if the runtime method signature doesn't match the signature of the method when the class was compiled. Another compile vs runtime mismatch is the NoClassDefFoundError.
In this case, it appears the version of Guava providing the com.google.common.base.Preconditions.checkState method the Springfox springfox.documentation.spring.web.scanners.CachingOperationReader class was compiled against doesn't match method signature of the method in the runtime (or possibly test) classpath.
You should run mvn dependency:tree -Dverbose -Dincludes=com.google.guava:guava, as documented here. Once you find which dependency(ies) are bringing in a version of Guava that conflicts with the version Springfox needs, you can add an exclusion to that other dependency(ies), or add an explicit dependency in your project with the version Springfox requires, to ensure the runtime/test classpath contains a compatible version.

spring boot error - Caused by: java.lang.IllegalStateException: Could not configure JTA platform

**I am using Java 6/Spring Framework 4.1.4/Spring Boot v1.2.1.RELEASE and Hibernate 3.5.

Why is it trying JTA (or how can I suppress the ComponentScan)?
What does this error mean and how to resolve it?
I have tried to use individual annotations instead of SpringBootApplication and have same error.

INFO: Stopping service Tomcat

Spring Boot does not support Hibernate 3.5.
Minimum required version is Hibernate 4.2.
You can work around that by completely disabling the auto configuration for Hibernate:
#EnableAutoConfiguration(exclude = {HibernateJpaAutoConfiguration.class})
If you do deploy your service as an executable JAR with embedded Tomcat, there is no reason to use such an old Hibernate version, so you should use the one which Spring Boot defines.

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.retry.annotation.EnableRetry;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
#Configuration
#ComponentScan
#EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class })
#EnableAsync
#EnableRetry
#EnableScheduling
public class RelayDesktopApp {
public static void main(String[] args) {
try {
SpringApplication app = new SpringApplication(RelayDesktopApp.class);
app.setHeadless(false);
app.run(args);
} catch (Throwable t) {
System.err.println(t.getMessage());
}
}
}
Not sure what is cause of this error: Error creating bean with name 'defaultServletHandlerMapping'.
I have NO where any #EnableWebMvc annotaions.
Any feedback ?

#EnableAutoConfiguration also does auto configs for WebMvc, so pls exclude this as well :-
#EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class,WebMvcAutoConfiguration.class })

By default SpringApplication, will deduce whether or not you're building a web application based on what's on the classpath. If you have some Web-related dependencies on the classpath but aren't building a web application, you can explicitly tell SpringApplication that you don't want a web application:
app.setWebEnvironment(false);
This is preferable to explicitly disabling Web-related auto-configuration as it means you don't need to know what those auto-configuration classes are and lets Spring Boot take care of it for you.

The same idea than Avis but in configuration file:
spring:
autoconfigure:
exclude:
- org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration

I use springboot and added following to application.properties file to overcome this exception:
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration,org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration,

Spring JUnit Test - Instantiation problems

I have a working Spring application compiled with maven and deployed on tomcat 7.
I'm trying to implements some test cases using JUnit 4. I successfully make some test for a part of the application but I get compilation problem when I want to test two parts which used external framework: Shiro and OIOSAML. Since there is no OIOSAML community here, I'll focus on shiro but I believe that the cause of the problem is the same.
When I try to load the application-context in the JUnit test, I obtains loading errors (see next). It looks like some dependencies can't be loaded/found in the frameworks part. Here is some helpful information:
Shiro exception:
org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'authorization' defined in class path resource [test-context.xml]:
Instantiation of bean failed;
nested exception is org.springframework.beans.BeanInstantiationException:
Could not instantiate bean class [myPackage.ShiroAuthorization]:
Constructor threw exception; nested exception is org.apache.shiro.config.ConfigurationException:
Unable to instantiate class [com.mysql.jdbc.jdbc2.optional.MysqlDataSource] for object named 'ds'.

I tried to play with the context file but nothing helps. Which is strange is I can successfully test the connection pool of tomcat 7 which shows that dependencies are correctly loaded.
I remind you that everything works except when I want to test it with JUnit.

Do you have mySql driver in your classpath? Probably that's the problem.

Try to annotate your JUnit test class using:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = {
"classpath:/test-context.xml"
})
This loads your applicationContext when running your JUnit tests.
Make sure your applicationContext xml is on your classpath.
