I am seeing many posts regarding this error , but no answers to fix this.

It's almost the same thing only annotation driven. In the Supplier I'm just casting mongoTemplate (You may not want that). So If you use the spring config everything should work fine.

Regarding your version in XML try creating the mongo factory from SimpleMongoDbFactory with a MongoClient and the database name, Then just give your MongoTemplate bean your factory, and that's it.

Spring Config:

@Configuration
public class SpringConfig {

    @Bean
    public MongoDbFactory mongoDbFactory() throws UnknownHostException{
        return new SimpleMongoDbFactory(new MongoClient(),"games");
    }

    @Bean
    public MongoTemplate mongoTemplate() throws UnknownHostException{
        MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());      
        return mongoTemplate;
    }

}

After that I created a supplier (Google Guava in this case) which may not be needed in your case

public class MongoOperationSupplier implements Supplier<MongoOperations>{
    @Override
    public MongoOperations get() {
        ApplicationContext ctx = new AnnotationConfigApplicationContext(SpringConfig.class);
        MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");
        return mongoOperation;
    }
}

An annotated class:

@Document(collection="game_suspicious_event")
public class SuspiciousEvent {
    @Id
    private String id;

    private String apiKey;
    private String userUniqueId;
    private Date date;
    private String ip;
    private String additionalInformation;

    public SuspiciousEvent(){}

    public SuspiciousEvent(String apiKey,String userUniqueId,Date date, String ip, String additionalInformation){
        this.apiKey=apiKey;
        this.userUniqueId=userUniqueId;
        this.date=date;
        this.ip=ip;
        this.additionalInformation=additionalInformation;
    }

    public String getApiKey() {
        return apiKey;  
    }
}

Then to use:

final MongoOperations mo = new MongoOperationSupplier().get();
mo.save(new SuspiciousEvent(......));

Hope it helps.

The version of spring-core need match the version of spring-data. Below is my part pom.xml:

  <dependency>
       <groupId>org.springframework</groupId>
       <artifactId>spring-core</artifactId>
       <version>4.2.4.RELEASE</version>
  </dependency>

  <!-- Spring data mongodb -->
  <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-mongodb</artifactId>
      <version>1.8.2.RELEASE</version>
  </dependency>

It's fixed.
