我使用azure cosmosdb和mongoAPI（spring data，mongoRepository） 每天早上，第一个从mongo获取数据的请求会导致异常：
以下请求成功而不执行任何操作。

您可以像这样设置keep-alive：
@Bean
public MongoDbFactory mongoDbFactory() throws Exception {
MongoClientOptions.Builder optionsBuilder = MongoClientOptions.builder();
optionsBuilder.socketKeepAlive(true);
return new SimpleMongoDbFactory(new MongoClientURI(mongoUri, optionsBuilder));
}

由于经过了最大的连接空闲时间，因此关闭了连接。
您将需要根据需要设置此属性。
maxConnectionIdleTime
这可以在您的Mongo配置或应用程序配置文件中设置。
祝你好运。
