mongodb spring 连接一夜之间丢失

Question

我正在使用带有 mongoAPI（spring 数据，mongoRepository）的 azure cosmosdb 每天早上，第一个从 mongo 获取数据的请求会导致异常：

后续请求无需执行任何操作即可成功。

知道是什么原因造成的吗？有没有办法让 spring 自动恢复连接而不会请求失败？

谢谢

您可以像这样设置保持活动状态：

    @Bean
    public MongoDbFactory mongoDbFactory() throws Exception {
        MongoClientOptions.Builder optionsBuilder = MongoClientOptions.builder();
        optionsBuilder.socketKeepAlive(true);
        return new SimpleMongoDbFactory(new MongoClientURI(mongoUri, optionsBuilder));
    }
