Optaplanner - spring BeanCreationException

I'm migrating Optaplanner from v7.x to v8.14 on a project that uses spring-boot (as a web api).
I've added the optaplanner-spring-boot-starter dependency to the project, however when starting the application, I got the following error :
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'solverManager' defined in class path resource [org/optaplanner/spring/boot/autoconfigure/OptaPlannerAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.optaplanner.core.api.solver.SolverManager]: Factory method 'solverManager' threw exception; nested exception is java.lang.IllegalStateException: The solutionClass (class be.my.domain.MySolution) has been specified as a solution in the configuration, but does not have a #PlanningSolution annotation.

The project is in two separated modules, one with everything related to Optaplanner (the config.xml, the .drl, the Solution, etc), the other is the spring-boot web api.
Here are the dependencies (.gradle) for both :

}
the SolverConfig file :
<solver xmlns="https://www.optaplanner.org/xsd/solver" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="https://www.optaplanner.org/xsd/solver https://www.optaplanner.org/xsd/solver/solver.xsd">
<solutionClass>be.my.domain.MySolution</solutionClass>
<entityClass>be.my.domain.DutyAssignment</entityClass>
...
</solver>
And the MySolution file :
package be.my.domain;
// Imports ...
#PlanningSolution
#XStreamAlias("MySolution")
public class MySolution extends AbstractPersistable {
private static final long serialVersionUID = 1L;
private String code;
//All the #ProblemFactProperty / CollectionProperty and the ProblemEntityCollectionProperty
#PlanningScore
private HardMediumSoftScore score;
public MySolution(){}
//A lot of getters
}
EDIT : The #PlanningSolution class and the configuration files are in one module, the solverConfig, solverFactory, scoreManager, etc. are all built in the other package, could this be an issue in v8+ ?

This is a bug in Optaplanner, the current workaround is to move the needed code from the different modules into one. Not ideal, but it works. To follow the issue : https://issues.redhat.com/browse/PLANNER-2600 Once resolved, this bug should not happen anymore.

When I just upgrade to Spring Boot 2.2.1, this exception doesn't occur.
After adding the dependency:
<dependency>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-jaxb-annotations</artifactId>
</dependency>
it works for 2.2.2.
So my question is, why do I suddenly need to manually add a dependency after this Spring Boot upgrade.

I would look at your dependencies which might use xml as configuration. I am using Spring Boot 2.3.1 and did not need this dependency until I added Liquibase support. Since I was using xml for the Liquibase configuration then I see same error at startup. Once I added this dependency then error went away.

Assuming your application is using / including Liquibase, this occurs because of an erroneous file in liquibase-core which is defining an SPI extension for a Jackson module but not providing the implementation for that module: https://github.com/liquibase/liquibase/issues/1051
The workaround listed in the OP is sufficient, as its providing the implementation to the Jackson module referenced in the SPI file, but you can also upgrade Liquibase to >= 3.10.1 to resolve this (I only tested 3.10.3 but according to the linked defect 3.10.1 should work)
For Gradle, the dependency is:
implementation 'org.liquibase:liquibase-core:3.10.3'

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.

Error creating bean with name 'dataSource': Invocation of init method failed

I'm very new to Spring Boot and was trying to do some tests. When I suddenly encounterd a problem I've been trying to solve for the past 3 hours...
I believe the main concern here is this:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.flyway.FlywayAutoConfiguration$FlywayConfiguration': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.autoconfigure.flyway.FlywayAutoConfiguration$FlywayConfiguration$$EnhancerBySpringCGLIB$$8cc0418d]: Constructor threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Failed to replace DataSource with an embedded database for tests. If you want an embedded database please put a supported one on the classpath or tune the replace attribute of #AutoConfigureTestDatabase
But neither the less, here are my ErrorLogs:

According to the exception
Failed to replace DataSource with an embedded database for tests. If you want an embedded database please put a supported one on the classpath or tune the replace attribute of #AutoConfigureTestDatabase.
Add first this property in the file (see the doc [https://docs.spring.io/spring-boot/docs/current/reference/html/howto-database-initialization.html]
[Database Initialization]
spring.datasource.platform=posgresql
Also, you should remove the bean declaration (duplicated from the datasource declared in the file application.properties , or add a #Qualifier for this specific bean.
#Bean
public DataSource dataSource() {
final DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
dataSource.setUrl(env.getProperty("jdbc.url"));
dataSource.setUsername(env.getProperty("jdbc.user"));
dataSource.setPassword(env.getProperty("jdbc.pass"));
return dataSource;
}
Also, in my case, I'm using flyway in a springboot application with a IBM Db2 datasource. I have to add explicitly this properties in my application.properties :
flyway.url=jdbc:db2://myserver:50000/mydbinstance
flyway.user=myuser
flyway.password=****

GraphQL and Spring Boot 2.0.3

I want to test GraphQL for a future project. The project will use Spring Boot, Spring Security, and GraphQL. So I created a new Spring Boot App in IntelliJ using the build in Spring Initializr. The Spring Boot version is, of course, the latest (2.0.3.RELEASE)
Now I add the dependencies for GraphQL and GraphiQL.
<dependency>
<groupId>com.graphql-java</groupId>
<artifactId>graphql-spring-boot-starter</artifactId>
<version>4.3.0</version>
</dependency>
<dependency>
<groupId>com.graphql-java</groupId>
<artifactId>graphql-java-tools</artifactId>
<version>5.2.0</version>
</dependency>
<dependency>
<groupId>com.graphql-java</groupId>
<artifactId>graphiql-spring-boot-starter</artifactId>
<version>4.3.0</version>
</dependency>
To test this, I ran the application but there was no /graphql endpoint. In this case, I configured it in application.properties without a problem:
# GraphQL
graphql.servlet.mapping=/graphql
graphql.servlet.enabled=true
graphql.servlet.corsEnabled=true
# GraphiQL
graphiql.mapping=/graphiql
graphiql.endpoint=/graphql
graphiql.enabled=true
graphiql.cdn.enabled=true
graphiql.cdn.version=0.11.11
After testing again, the endpoint is there, so now I could write a schema, resolvers and so on. This is what I implemented:
Schema:
schema {
query: Query
mutation: Mutation
}
type Greeting {
id: ID!
message: String!
}
type Query {
greetingsAll: [Greeting]
}
type Mutation {
greeting(message: String!): Greeting
}
Model:
#NoArgsConstructor
#AllArgsConstructor
#Getter
#Setter
#Builder
#ToString
#Entity
public class Greeting {
#Id
#GeneratedValue
private Long id;
private String message;
}
Repository
#Repository
public interface GreetingRepository extends JpaRepository<Greeting, Long> {
}
QueryResolver
#Component
public class QueryResolver implements GraphQLQueryResolver {
#Autowired
private GreetingRepository greetingRepository;
public Greeting greeting(Long id) {
return greetingRepository.getOne(id);
}
public Iterable<Greeting> getGreetingsAll() {
return greetingRepository.findAll();
}
}
MutationResolver
#Component
public class MutationResolver implements GraphQLMutationResolver {
#Autowired
private GreetingRepository greetingRepository;
public Greeting newGreeting(String message) {
Greeting greeting = new Greeting();
greeting.setMessage(message);
return greetingRepository.save(greeting);
}
}
Beans for SpringBoot
#SpringBootApplication
public class GraphqlApplication {
public static void main(String[] args) {
SpringApplication.run(GraphqlApplication.class, args);
}
#Bean
ApplicationRunner init(GreetingRepository greetingRepository) {
return args -> {
Stream.of("Hallo", "Guten Tag", "Moin").forEach(greeting -> greetingRepository.save(Greeting.builder().message(greeting).build()));
greetingRepository.findAll().forEach(System.out::println);
};
}
#Bean
public QueryResolver query() {
return new QueryResolver();
}
#Bean
public MutationResolver mutation() {
return new MutationResolver();
}
}
While trying to test the application again to see if I could run a query using GraphiQL, the application wouldn't start:

So I don't know what happened but I think GraphQL can not map the Query type to the QueryResolver. But why?
When checking the internet, I read that Spring Boot Version is the reason. So I tested it with Spring Boot 1.5.8.RELEASE, without result.
However, when using an older GraphQL version (4.3.0 and 5.2.0) with Spring boot 1.5.8, it did seem to work fine. So then I tried to use these older GraphQL versions with the new Spring boot version, but then I get another exception:

Now I'm really screwed up because of this incompatibility. I want to use the new versions of all libraries. Does anybody have a solution?

You're creating your resolver beans twice. Both your MutationResolver and QueryResolver are annotated with #Component, which means that Spring will create an instance and register it. However, within the GraphqlApplication you also created beans for both resolvers using the #Bean annotation.
This causes an issue, because the GraphQL library will look for a proper resolver for greetingsAll, but it will find two resolvers due to your bean being mapped twice.
The solution is to either remove the #Component annotation, or to remove the following bean configuration:
#Bean
public QueryResolver query() {
return new QueryResolver();
}
#Bean
public MutationResolver mutation() {
return new MutationResolver();
}
