如何禁用 mongodb java 驱动程序的 DefaultServerMonitor 线程

Question

我将 apache 元模型添加到我的项目中。

<dependency>
    <groupId>org.apache.metamodel</groupId>
    <artifactId>MetaModel-full</artifactId>
    <version>5.0.0</version>
</dependency>

mongo-java-driver 作为依赖项出现。

[INFO] |  +- org.apache.metamodel:MetaModel-mongodb-mongo3:jar:5.0.0:compile
[INFO] |  |  +- org.apache.metamodel:MetaModel-mongodb-common:jar:5.0.0:compile
[INFO] |  |  \- org.mongodb:mongo-java-driver:jar:3.4.3:compile
[INFO] |  +- org.apache.metamodel:MetaModel-mongodb-mongo2:jar:5.0.0:compile

然后我看到一些日志，比如。

2018-01-16 02:33:09.467  INFO 15417 --- [  restartedMain] org.mongodb.driver.cluster               : Cluster created with settings {hosts=[localhost:27017], mode=SINGLE, requiredClusterType=UNKNOWN, serverSelectionTimeout='30000 ms', maxWaitQueueSize=500}

当我挖掘 mongo-java-driver 的源代码时，我看到 mongo-java-driver 启动一个线程来监视默认的 mongodb 服务器。我不想排除 mongodb 驱动程序，但如何禁用 com.mongodb.connection.DefaultServerMonitor 线程。

经过进一步搜索，我意识到这是 spring-boot 自动配置问题。我的应用程序是一个 spring-boot 应用程序。spring-boot 自动配置在类路径中找到 mongos-java-driver jar 并启动 mongo-drive。

添加@EnableAutoConfiguration(exclude = {MongoAutoConfiguration.class})后，mongo-java-driver 不再启动。
