Could not find class [org.springframework.boot.autoconfigure.condition.OnBeanCondition]

Im using feign client to make rest calls between microservices, When i execute it using IntelliJ IDEA its working fine. But if i execute it with jar it gives me following error.
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [org.springframework.cloud.netflix.eureka.loadbalancer.EurekaLoadBalancerClientConfiguration]; nested exception is java.lang.IllegalArgumentException: Could not find class [org.springframework.boot.autoconfigure.condition.OnBeanCondition]

We had the same issue. After a research we found out that the issue is similar to described in the feign client bug.
The temporary fix provided by DenisKorolev resolves the issue by setting correct ClassLoader during context initialisation.
#Bean
#ConditionalOnMissingBean
public LoadBalancerClientFactory loadBalancerClientFactory(LoadBalancerClientsProperties properties) {
return new LoadBalancerClientFactory(properties) {
#Override
protected AnnotationConfigApplicationContext createContext(String name) {
// FIXME: temporary switch classloader to use the correct one when creating the context
ClassLoader originalClassLoader = Thread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
AnnotationConfigApplicationContext context = super.createContext(name);
Thread.currentThread().setContextClassLoader(originalClassLoader);
return context;
}
};
}

ClassNotFoundException while running jar on Amazon Kinesis Streaming Analytics app

I have created a Kinesis Analytics Streaming Application in SpringBoot which will consume messages from the AmazonKinesis input stream and will do some operations on top of it using the Apache Flink DataStream library.
When, I am uploading the application jar to S3 and trying to run this application on Streaming App it is throwing ClassNotFoundException for one of the files which is the ApplicationConfiguration file. Also, when I am running this application locally, it is running fine without any errors and I am able to consume the messages.

Things that I have tried on my end:
Clean build the project a couple of times.
Checked Java and Spring version in pom, as suggested in one of the
StackOverflow post.
Downgraded SpringBoot version from "2.7.0" to "2.4.0".
Added ComponentScan annotation in main class.
Tried changing the annotation from #Configuration to #Component.
Last but not least, tried google and stackoverflow.
Can someone please help me identify the error?

Is this because you're attempting to use dependencies for flink 1.15? AFAIK, 1.13 is the latest version supported. You need to choose which flink version you intend to use when creating the streaming application.

How to use embedded MongoDB with SpringBoot v2.6.2?

I'm using Spring Boot v2.6.2 and Java v17 and trying to test my MongoConnection without having a MongoDBService running because it should be tested with embedded in-memory MongoDB on the build machine, no need to set up an extra MongoDB service there.
For sure on the productive system, it should use a full MongoDB.
I try to get this easy example running:
#DataMongoTest
public class MongoTest
{
#Autowired
private UserRepository userRepository;
#AfterEach
void cleanUpDatabase()
{
this.userRepository.deleteAll();
}
#Test
void bootstrapTestDataWithMongoTemplate() {
final var restaurant = new User( "123", "ABC", "DEF" );
this.userRepository.insert( restaurant );
final var found = this.userRepository.findByFirstName( "ABC" );
System.out.println( found );
}
}
UserRepository is an interface that extends MongoRepository. User itself is just a DBEntity with #Document annotation. If I let the SpringBoot application run, not in test mode, everything works fine, because MongoDB is running at the specified location. But for the test, I want to let it run as an in-memory DB.
But Springboot wants to connect for the test.

Any suggestions on how to do this? Is #DataMongoTest testing in the wrong way? I thought the integrated flapdoodle dependency would inject it automatically in the test case.

The documentation states:
2.2.4. Embedded Mongo
Spring Boot offers auto-configuration for Embedded Mongo. To use it in
your Spring Boot application, add a dependency on
de.flapdoodle.embed:de.flapdoodle.embed.mongo and set the
spring.mongodb.embedded.version property to match the version of
MongoDB that your application will use in production. The default
download configuration allows access to most of the versions listed in
Embedded Mongo’s Version class as well as some others. Configuring an
inaccessible version will result in an error when attempting to
download the server. Such an error can be corrected by defining an
appropriately configured DownloadConfigBuilderCustomizer bean.
The port that Mongo listens on can be configured by setting the
spring.data.mongodb.port property. To use a randomly allocated free
port, use a value of 0. The MongoClient created by
MongoAutoConfiguration is automatically configured to use the randomly
allocated port. If you do not configure a custom port, the embedded
support uses a random port (rather than 27017) by default.
If you have SLF4J on the classpath, the output produced by Mongo is
automatically routed to a logger named
org.springframework.boot.autoconfigure.mongo.embedded.EmbeddedMongo.
You can declare your own IMongodConfig and IRuntimeConfig beans to
take control of the Mongo instance’s configuration and logging
routing. The download configuration can be customized by declaring a
DownloadConfigBuilderCustomizer bean.
Therefore add the below dependency in scope:test if you want it to only be applied for Tests.
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<scope>test</scope>
</dependency>
As well you need to set the version in your application.properties file:
spring.mongodb.embedded.version=4.0.21

Its a simple spring boot app with rest controller.
Calling http://localhost:8084/springboot_test/ loads the default index.html page
The problem is when I call http://localhost:8084/springboot_test/home it is not printing the output System.out.println("###Home Controller Called"); so I guess the request is not called on rest controller itself. But why it isn't called?
Update
Using the #ComponentScan("com.rsc.springboot_test") on rest Controller as suggested by #javaguy works but I want to apply the #componentScan on top of main class so that it scans all packages on startup.
Trying the following gives error:
#SpringBootApplication
#ComponentScan(basePackages = { "com.rsc.*" })
public class SpringBootTest {
public static void main(String[] args) {
SpringApplication.run(SpringBootTest.class, args);
}
}

Your RestController is NOT detected by the Spring container, so you need to add the package details to ComponentScan, so change the main as below:
#SpringBootApplication
#ComponentScan(basePackages = { "com.rsc" })
public class SpringBootTest {
public static void main(String[] args) {
SpringApplication.run(SpringBootTest.class, args);
}
}
Also, for your test application, you don't need any xml (as we are using annotations and scanning the components using componentscan), seems like you have configured one at the below path:
C:\Users\Documents\AppData\Roaming\NetBeans\8.2\apache-tomcat-8.0.27.0_base\conf\Catalina\localhost\springboot_test.xml
You need to delete and restart the server.

#SpringBootApplication by default triggers component scanning on the same package as annotated class and all subpackages.
In your case, since main class is in com.rsc.springboot_test and controller in com.rsc.springboot_test_controller, TestController class will not be scanned.
There are two approaches to solve it:
recommended: move TestController to another package so that it matches default classpath scanning, for example to com.rsc.springboot_test.controller
modify #SpringBootApplication to scan other packages:
#SpringBootApplication(scanBasePackages = {
"com.rsc.springboot_test",
"com.rsc.springboot_test_controller"
})

Your problem is, that your Application class is under ComponentScan. Your project structure should be:
src
main
java
com.company
Application.java
controller
MyController.java
service
repository
And your Application:
#SpringBootApplication
#ComponentScan(basePackages = {
"com.rsc.springboot_test_controller",
"com.rsc.springboot_test_service",
//etc... no ' at the end of the last package
})
public class SpringBootTest {
public static void main(String[] args) {
SpringApplication.run(SpringBootTest.class, args);
}
}
Actually the above is the mixture of two different approaches but will work. Remember, that your Application.java should be in the root package for all other packages.
And reading your question once again, I would recommend to change the Controller:
package com.rsc.springboot_test_controller;
#RestController
public class testController {
#RequestMapping("/home")
public String home() {
return "###Home Controller Called";
}
}
