I have updated the following spring dependencies in my project pom.xml
From:
<spring.version>5.3.6</spring.version>
<spring.security.version>5.4.4</spring.security.version>
<spring.boot.version>2.3.10.RELEASE</spring.boot.version>
To:
<spring.version>5.3.8</spring.version>
<spring.security.version>5.5.1</spring.security.version
<spring.boot.version>2.5.2</spring.boot.version>
I was able to build my project successfully whereas, when I tried to start my application, I see the following error and my application fails to start at all.
Can any one help me with the resolution.

Warning!
This is not Production Grade solution but this may be considered as starting point for further investigation.
Background
We have quite legacy (~10yo) application and we currently run into same issue during Spring Boot upgrade from 2.3.9 to 2.4.0 (Full stack below).
It seems to me that problem is related to three issues:
ProtectPointcutPostProcessor - from spring security
MethodValidationPostProcessor - which lack of disables the error
change in Spring Boot 2.4.0 - which is described below
Possible cause description
In Spring Boot 2.4.0 new Bean has been introduced in EnableConfigurationPropertiesRegistrar:
static void registerMethodValidationExcludeFilter(BeanDefinitionRegistry registry) {
if (!registry.containsBeanDefinition(METHOD_VALIDATION_EXCLUDE_FILTER_BEAN_NAME)) {
BeanDefinition definition = BeanDefinitionBuilder
.genericBeanDefinition(MethodValidationExcludeFilter.class,
() -> MethodValidationExcludeFilter.byAnnotation(ConfigurationProperties.class))
.setRole(BeanDefinition.ROLE_INFRASTRUCTURE).getBeanDefinition();
registry.registerBeanDefinition(METHOD_VALIDATION_EXCLUDE_FILTER_BEAN_NAME, definition);
}
}
This bean is generated with MethodValidationExcludeFilter.byAnnotation as Lambda:
static MethodValidationExcludeFilter byAnnotation(Class<? extends Annotation> annotationType,
SearchStrategy searchStrategy) {
return (type) -> MergedAnnotations.from(type, SearchStrategy.SUPERCLASS).isPresent(annotationType);
}
Because of being Lambda it has no parent class and fails miserably on bean creation post processing.
(Very) hacky solution
Luckily EnableConfigurationPropertiesRegistrar.registerMethodValidationExcludeFilter contains if statement which checks if bean has not been created. So we may create this bean manually instead:
#Bean("org.springframework.boot.context.properties.EnableConfigurationPropertiesRegistrar.methodValidationExcludeFilter")
public MethodValidationExcludeFilter mockMethodValidationExcludeFilter() {
return new MethodValidationExcludeFilter() {
#Override
public boolean isExcluded( Class< ? > type ) {
return MethodValidationExcludeFilter.byAnnotation( ConfigurationProperties.class).isExcluded( type );
}
};
}
Or even as:
#Bean("org.springframework.boot.context.properties.EnableConfigurationPropertiesRegistrar.methodValidationExcludeFilter")
public String mockMethodValidationExcludeFilter() {
return "mockMethodValidationExcludeFilter";
}
But this seems to me as very dirty hack and not suitable for production usage.
Theoretically disabling linting error cantFindType could also save the day as doing it on debug has allowed application to run but
we have not achieved proper configuration to disable it
this seems as dirty hack as well and should be considered as last resort and not proper solution

See here full log.
I'm using spring-boot-starter-web package which includes Tomcat as a default implementation of a servlet. Seems that exception is thrown because the bean which extends WebMvcConfigurationSupport is created earlier than expected and before the ServletContext is available.
I was trying to change or remove some annotations on WebConfig.java, SecurityConfig.java and CoreApplication.java but always the result is the same.
As a test, if #EnableAutoConfiguration(exclude = { WebMvcAutoConfiguration.class }) is implemented on CoreApplication.java, the exported jar is runned as standalone application without any issue.
So how can I configure WebMvcAutoConfiguration.class in order to run the application waiting for incoming http requests? How can I do in order to build later the bean which extends WebMvcConfigurationSupport and after the ServletContext is available?
Here my repo where there is pom.xml, application.properties, config classes, controllers, main application, models and repositories.
Thanks
There was some problem when build jar from Build -> Build Artifacts -> Rebuild. Seems that tomcat is not embeeded with this configuration.
If I build jar from maven menu into Intellij, the exception dissapear.
I am working on a spring boot upgrade project where i am upgrading spring boot version 2.2.7.RELEASE to Spring boot 2.6.7 and also upgrading spring cloud config server to 2021.0.2. In my config server, I am using #Value annotation to pick property from GIT URL.

Your help is really appreciated.
I use this kafka configuration with spring cloud and spring boot 2.6.6:
#Configuration
#RefreshScope
public class KafkaProducerConfig {
#Bean(name = "nativeProducerFactory")
#Primary
#RefreshScope
public ProducerFactory<String, String> nativeProducerFactory() {
final Map<String, Object> properties = new HashMap<>();
properties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
properties.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
properties.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
return new DefaultKafkaProducerFactory<>(properties);
}
#Bean(name = "nativeKafkaTemplate")
public KafkaTemplate<String, String> nativeKafkaTemplate(
#Autowired final ProducerFactory<String, String> factory) {
return new KafkaTemplate<>(factory);
}

Description:
Parameter 0 of method kafkaTemplate in org.springframework.boot.autoconfigure.kafka.KafkaAutoConfiguration required a bean of type 'org.springframework.kafka.core.ProducerFactory' that could not be found.
The following candidates were found but could not be injected:
- User-defined bean method 'nativeProducerFactory' in 'KafkaProducerConfig'
Action:
Consider revisiting the entries above or defining a bean of type 'org.springframework.kafka.core.ProducerFactory' in your configuration.
Do you know how I can fix this issue?
When I remove #RefreshScope from the bean it's working fine. Do you know how I can fix this issue?
P.S Looks like adding #RefreshScope also like this solves the error:
#Bean(name = "nativeKafkaTemplate")
#RefreshScope
public KafkaTemplate<String, String> nativeKafkaTemplate(
#Autowired final ProducerFactory<String, String> factory) {
return new KafkaTemplate<>(factory);
}
But I think that is incorrect. Any idea what should be the correct way to fix this?
The issue is related to the #RefreshScope on the #Configuration class. Better define #RefreshScope for the specific #Bean.
Accrding to Spring Cloud Context - Refresh Scope
#RefreshScope works (technically) on an #Configuration class, but it
might lead to surprising behavior. For example, it does not mean that
all the #Beans defined in that class are themselves in #RefreshScope.
Specifically, anything that depends on those beans cannot rely on them
being updated when a refresh is initiated, unless it is itself in
#RefreshScope. In that case, it is rebuilt on a refresh and its
dependencies are re-injected. At that point, they are re-initialized
from the refreshed #Configuration)
Tha's why it's working when you move it to the #Bean.

Optaplanner is an AI library which helps solve planning and scheduling problems.
My goal is to use Jhipster to develop quickly a platform which resort to optaplanner to solve a specific problem, and finally deploy the code on Google Kubernate.
I finally come with a solution by merging examples codes from Optaplanner and Jhipster.
As shown in the folowing output, it works well on my machine on local.After installing Jhipster :
jhipster
mvn package -Pprod jib:dockerBuild
java -jar target/jhipster-0.0.1-SNAPSHOT.jar

This is the code for the SolverManager bean injection, based on the Jhipster examples code:
#RestController
#RequestMapping("/api")
public class TimeTableResource {
private TimeTableRepository timeTableRepository;
private SolverManager<TimeTable, Long> solverManager;
public TimeTableResource(TimeTableRepository timeTableRepository, SolverManager<TimeTable, Long> solverManager) {
this.timeTableRepository = timeTableRepository;
this.solverManager = solverManager;
}
/**
* {#code POST /solve}
*/
#PostMapping("/solve")
public void solve(TimeTableRepository timeTableRepository, SolverManager<TimeTable, Long> solverManager) throws URISyntaxException {
log.debug("REST request to solve ");
solverManager.solveAndListen(TimeTableRepository.SINGLETON_TIME_TABLE_ID, timeTableRepository::findById, timeTableRepository::save);
}
}
The full code can be found here.
I don't understand why this "Unsatisfied dependency" happens when deployed on gke whereas there is no such error on local machine, nor on gce.
Can someone help me solve this?
There is a NullPointerException lurking in the stack trace:
java.lang.NullPointerException: null at java.compiler#11.0.12/javax.tools.ToolProvider.lambda$matches$0(Unknown Source)
Having never seen this exception before, I can make an educated guess: could it be that you don't have a Java compiler on the machine? Please install a full JDK (one that brings javac as well as java) and this problem may go away.
The reason for that is that Constraint Streams - in order to generate the code for your constraints - will need to compile some Java classes into bytecode. And without javac, that is not possible.
I have a person model class that needs to be immutable and singleton. I need to autowire from my service class but getting an error.
So is there any way to create a singleton immutable class in spring boot? where i can set values in person (via autowire) and use the same in the entire application.
I have just started learning spring-boot. I searched on google and found the solution with Lombok but somehow it didn't work for me.
My person model :
#Value
#Builder
#AllArgsConstructor(access = AccessLevel.PRIVATE)
#Component
public final class Person {
private final String firstName;
private final String lastName;
}
//My service class
#Component
public class ArgumentReadingService {
#Autowired
Person person;
public void readArguments() {
person = Person.builder().firstName("Hello").build();
System.out.println("name : "+person.getFirstName());
}

This configuration class and that annotation will provide you always with that Person Bean
#Configuration
public class ServerConfig
{
#Bean
private Person getPerson(){
return new Person("name", "lastName");
}
Now it will be available everywhere for autowiring.
As the comments note however, it seems strange to use a model class as a Singleton.
Adding some more info for the readers,
Look at this question for more clarity
SpringBoot - #Configuration creates a singleton bean
