I'm a complete novice regarding Spring applications, and I'm trying to integrate a project using Kotlin + Spring + GORM (Which requires usage of Groovy). When I try to run it I get:

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'messageController': Unsatisfied dependency expressed through method 'setTargetDatastore' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException

I have just 5 files in the project, including the build.gradle.

Message.groovy

import grails.gorm.annotation.Entity

import groovy.transform.ToString

import org.grails.datastore.gorm.GormEntity



@ToString

@Entity

class Message implements GormEntity<Message> {

    String user;

    String date;

    String message;

}

Message.service

import domain.Message

import groovy.transform.CompileStatic

import org.springframework.stereotype.Service



@CompileStatic

@grails.gorm.services.Service(Message)

@Service

interface MessageService {

    List<Message> findAll()

}

MessageController.groovy

@RestController

@Transactional

class MessageController {



    @Autowired

    MessageService messageService



    @RequestMapping("/")

    List<String> index() {

        return messageService.findAll().collect { "[" + it.user + "@" + it.date + ": " + it.message + "]" }

    }



    @RequestMapping(value = "/save/", method = RequestMethod.POST)

    String save(@RequestBody Message message) {

        message.save()

        return "Saved"

    }

}

App.kt

@SpringBootApplication

class SimManagerApplication



fun main(args: Array<String>) {



    SpringApplication.run(SimManagerApplication::class.java, *args)

}

build.gradle dependencies

dependencies {

    compile('org.springframework.boot:spring-boot-starter-quartz')

    compile('org.springframework.boot:spring-boot-starter-web')

    compile('com.fasterxml.jackson.module:jackson-module-kotlin')

    compile('com.vaadin:vaadin-spring-boot-starter')

    compile('org.flywaydb:flyway-core')

    compile("org.jetbrains.kotlin:kotlin-stdlib-jdk8")

    compile("org.jetbrains.kotlin:kotlin-reflect")



    compile("com.h2database:h2")



    compile("eu.vaadinonkotlin:vok-rest:0.6.2")

    compile('org.codehaus.groovy:groovy-all:2.5.4')

    compile("org.flywaydb:flyway-core:5.2.0")



    compile "org.grails:gorm-hibernate5-spring-boot:6.1.6.RELEASE"

    compile "org.hibernate:hibernate-core:5.1.0.Final"

    compile "org.hibernate:hibernate-ehcache:5.1.0.Final"



    runtime "org.apache.tomcat:tomcat-jdbc:8.5.0"

    runtime "org.apache.tomcat.embed:tomcat-embed-logging-log4j:8.5.0"

    runtime "org.slf4j:slf4j-api:1.7.10"



}

and as simple as that, the project fails to start. What, exactly, causes the UnsatisfiedDependencyException? Is there a simple straightforward way to solve it?.

Thank you very much in advance.
