Spring Boot Starter-Web尝试在启动时连接到Mongo

我在使用Spring Boot和MongoDB外部驱动程序时遇到了一些问题 . 我不能使用Spring Data MongoDB项目，因为我需要使用Mongo给出的ufficial异步驱动程序 . 但是，我需要使用Spring Boot，因为我正在开发的模块是使用该库的更大项目的一部分 .

这是我的 pom.xml 文件 .

详细地说，我使用的是Spring Boot 1.4.1和Mongo Async Driver 3.2.2 .

这是我的申请 .

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
public class TxViewApplication {
    public static void main(String[] args) {
        SpringApplication.run(TxViewApplication.class, args);
    }

    @Value("${mongo.uri}")
    private String mongoUri;

    @Bean
    public MongoClient mongoClient() {
        return MongoClients.create(mongoUri);
    }
}

它遵循我目前唯一的（空）测试 .

@SpringBootTest
@RunWith(SpringRunner.class)
public class ApplicationTest {
    @Test
    public void loadContext() throws Exception {}
}

我在这个项目中有 no other code . 当我运行测试时，我有以下错误：

2016-11-22 15:43:58.597  INFO 4572 --- [null'}-db:27017] org.mongodb.driver.cluster               : Exception in monitor thread while connecting to server db:27017

如您所见，我已在 SpringBootApplication 注释中正确插入了 exclude 子句，以便阻止Spring Boot尝试处理自己与Mongo的连接，如Mongo tries to connect automatically to port 27017(localhost)中所述 .

我还注意到，在将 pom.xml 添加到 spring-boot-starter-web 之后，我开始出现错误 .

如何禁止Spring Boot尝试在启动时自动连接到Mongo？ MongoDB驱动程序的同步版本存在同样的问题 .

--- EDIT ---

我还尝试以这种方式围绕 async.MongoClient 对象构建一个包装器：

public class MongoWrapper {
    private final MongoClient mongo;

    public MongoWrapper() {
        mongo = MongoClients.create();
    }

    public MongoClient getMongo() {
        return mongo;
    }
}

配置已相应更改 .

@Bean
public MongoWrapper mongo() {
    return new MongoWrapper();
}

不幸的是，没有任何改变 . Spring Boot似乎也以这种方式拦截 MongoClient 对象:(

非常感谢 .
