Mongodb not working in spring, how to fix??

Question

MongoDB

ApplicationContext ctx = new AnnotationConfigApplicationContext(SpringMongoConfig.class);
        MongoOperations mongoOperation = (MongoOperations)ctx.getBean("mongoTemplate");
        mongoOperation.save(new User("Name"));

@Configuration
public class SpringMongoConfig extends AbstractMongoConfiguration {

    @Override
    public String getDatabaseName() {
        return "yourdb";
    }

    @Override
    @Bean
    public com.mongodb.Mongo mongo() throws Exception {
        return new MongoClient("127.0.0.1");
    }
}

If I run the project with this code, I get this error:

HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoSuchMethodError: org.springframework.core.annotation.AnnotatedElementUtils.findMergedAnnotation(Ljava/lang/reflect/AnnotatedElement;Ljava/lang/Class;)Ljava/lang/annotation/Annotation;

If you remove the save method, everything will work. I can't figure out what's wrong. Help.
Database created, collection not created.

Answer 1

Judging by the error, your problem is using dependencies that are incompatible with each other. The specified method appeared in Spring Core version 4.2.
