我看到关于此错误的许多职位，但没有答案，解决这个问题。

嗨，也许这是有用的它几乎相同的东西只有注释驱动。在供应商我只是铸造mongoTemplate（你可能不希望这样）。所以如果你使用spring配置，一切都应该正常工作

关于你在XML中的版本，尝试用SimpleMongoDbFactory和MongoClient以及数据库名称创建mongo工厂，然后把你的MongoTempleate bean放到你的工厂，就是这样。

Spring配置

@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; 
    } 

} 

之后，我ccreated供应商（谷歌番石榴在这种CAS），这可能不是你的情况

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

的anotated

@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; 
    } 
} 

类需要

然后使用

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

希望它有帮助

spring-core的版本需要与spring-data的版本相匹配。 以下是我的部分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> 

它是固定的。
