Java 创建MongoDbFactory实例时出现异常

SpringJava配置是

@Configuration
public class MongoConfiguration {

    public @Bean MongoClientFactoryBean mongo() {
        MongoClientFactoryBean mongo = new MongoClientFactoryBean();
        mongo.setHost("localhost");
        return mongo;
    }

    public @Bean MongoDbFactory mongoDbFactory() throws Exception {
        return new SimpleMongoDbFactory(mongo().getObject(), "database");
    }

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

为了便于讨论，请尽可能选择最简单的消费者

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=MongoConfiguration.class)
public class TestMongo {


    @Autowired 
    MongoTemplate mt;

    @Test
    public void testMongoNotNull() {
        assertNotNull(mt);
    }
}

这给了我一个例外
