error creating bean - nested exception is java.lang.stackoverflow error spring data elasticsearch repository

Question

I am trying to configure Spring Data Elasticsearch in my Spring MVC project.I am following Java configuration. Following is my config class for elasticsearch as suggested here.

public class ESConfig {

    @Configuration
    @EnableElasticsearchRepositories(basePackages="com/estore/es/repository")   
    static class ElasticConfig{
        @Bean
        public ElasticsearchOperations elasticsearchTemplate() {            
            return new ElasticsearchTemplate(nodeBuilder().local(true).node().client());
        }

        @Bean
        public NodeBuilder nodeBuilder(){
            final NodeBuilder nodeBuilder = NodeBuilder.nodeBuilder();
            return nodeBuilder;     
        }

        @Bean
        public Node node(){
            return nodeBuilder().node();        
        }

        @Bean
        public Client client(){
            return node().client();
        }
    }

}

I am trying to autowire MerchantRepository into MerchantService.

MerchantRepository.java

public interface MerchantRepository extends ElasticsearchRepository<Merchant, Integer> {

}

MerchantService.java

@Transactional
@Service
public class MerchantService {

    @Autowired
    private MerchantDao merchantDao;

    @Autowired
    private MerchantRepository merchantRepository;

    public String addMerchant(Merchant merchant){   
        merchantRepository.save(merchant);      
        return "success";
    }

}

But Autowiring fails giving following exception:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'merchantService' defined in file [D:\Hemraj-Dev\apache-tomcat-7.0.57\webapps\estore\WEB-INF\classes\com\estore\service\MerchantService.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [com.estore.es.repository.MerchantRepository]: : Error creating bean with name 'merchantRepository': Invocation of init method failed; nested exception is java.lang.StackOverflowError; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'merchantRepository': Invocation of init method failed; nested exception is java.lang.StackOverflowError

-------same exception repeated as it is recusrsively making call to each other-------

Any suggestion? I guess I am missing something in configuration.

Answer 1

I got the same error but in different web application and different bean creation of course (I assume your application is also a web app), my application is onebusaway/oba. Here is the error I got when starting tomcat server within Eclipse Kepler on Windows 7 development machine:

Error creating bean with name 'transitGraphDaoImpl': Invocation of init method failed; 
nested exception is java.lang.StackOverflowError

I believe "This error is thrown to indicate that the application’s stack was exhausted, due to deep recursion." from reading source

Solution:

1. Double click on existing tomcat 7 server in Servers tab of Eclipse Kepler IDE, a configuration window will open
2. Click "Open launch configuration"
3. Click "Arguments" tab

4. in "VM Arguments" box paste this line (change it accordingly to your environment)

   -Dcatalina.base="C:\Program3\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2
   -Dcatalina.home="C:\Program3\tomcat7" 
   -Dwtp.deploy="C:\Program3\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps
   -Djava.endorsed.dirs="C:\Program3\tomcat7\endorsed" -Xms256m -Xmx1g -XX:MaxPermSize=2g
   

5. Click "apply" and "ok", then stop and start your server within Eclipse Servers tab again.

It works for me.

Note:

The key thing to keep in mind here is:

1. in my case I have issue with tomcat's memory
2. hence I increased the memory size like this -Xms256m -Xmx1g -XX:MaxPermSize=2g I have 16gig available. To understand Java memory settings read this

hope it helps.

Answer 2

I've got similar problem. I think that Spring has problem with entities with parameterized types which are self referencing. In my case, I've got classes:

public class Input<V> {
    private Pipe<V> pipe;
    ...
}

and

public class Pipe<V> {
    private Input<V> input;
    ...
}

which produce same stacktrace as yours. I suggest you to check if your Merchant class, or it's subclass, or one of fields is or has parameterized type.
