SpringBoot 3 +reactiveElasticSearch：AOT/native/GraalVM：在 org.springframework.data.elasticsearch.support.VersionInfo.loadVersionProperties 找不到

Question

Small question regarding the new Spring Boot 3 with AOT/native/GraalVM please

Lately, many talks regarding the new Spring Boot 3 are about the AOT/native/GraalVM.

I went to try migrating a project which was building without GraalVM, to this new paradigm so many are talking about.

Here is the straightforward code of the project:

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

package com.example.demo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Mono;

@RestController
public class ElasticController {

    private final ElasticRepository elasticRepository;

    @Autowired
    public ElasticController(ElasticRepository elasticRepository) {
        this.elasticRepository = elasticRepository;
    }

    @PostMapping(path = "/save", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    public Mono<String> save(@RequestBody ElasticPojo elasticPojo) {
        return elasticRepository.save(elasticPojo).map(__ -> "with graalVM, is is not working");
    }

}

package com.example.demo;

import org.springframework.data.repository.reactive.ReactiveCrudRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface ElasticRepository extends ReactiveCrudRepository<ElasticPojo, String> {

}

package com.example.demo;

import org.springframework.context.annotation.Configuration;
import org.springframework.data.elasticsearch.client.ClientConfiguration;
import org.springframework.data.elasticsearch.client.elc.ReactiveElasticsearchConfiguration;

import java.time.Duration;

@Configuration
public class ElasticConfiguration extends ReactiveElasticsearchConfiguration {

    @Override
    public ClientConfiguration clientConfiguration() {
        return ClientConfiguration.builder().connectedTo("localhost:9200").withConnectTimeout(Duration.ofMinutes(2L)).withSocketTimeout(Duration.ofMinutes(2L)).build();
    }

}

package com.example.demo;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;

@Document(indexName = "question")
public class ElasticPojo {

    @Id
    private String id;

    private String link;

    public ElasticPojo(String id, String link) {
        this.id = id;
        this.link = link;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getLink() {
        return link;
    }

    public void setLink(String link) {
        this.link = link;
    }

    @Override
    public String toString() {
        return "ElasticPojo{" +
                "id='" + id + '\'' +
                ", link='" + link + '\'' +
                '}';
    }

}

The GraalVM version is: graalvm-ce-java17-22.3.0

While running mvnw.cmd -Pnative native:compile the project builds fine, running the native image always yields this error:

To avoid confusion, I am building and running fine the same code with openJDK, and any other JDK. Actually, even with GraalVM, but not using the native, it compiles and runs fine.

Only when compiling native, and running native, the issue occurs, 100% of the time.

May I ask what am I doing wrong please?

Thank you

Answer 1

In the non-native variant we'll get an IOException when the resource is missing and ignore that. But the native application throws an IllegalStateException .

Thanks for creating this issue . I am currently working on it. It's not only the version.properties but some other options that need to be set in the RuntimeHintsRegistrar . Should be done in the next days.
