我無法使用 spring 啟動連接到 mongo db atlas

Question

我有一個 spring 微服務應用程序鏈接到 mongodb atlas 數據庫，昨天我的項目工作正常但今天我收到這個錯誤

這是我的 application.properties 文件

spring.data.mongodb.uri=mongodb+srv://denver:*****@product-service.wt2swod.mongodb.net/?retryWrites=true&w=majority
spring.data.mongodb.database=product-service

eureka.client.fetch-registry=true
eureka.client.service-url.defaultZone=http://localhost:8761/eureka

spring.application.name=product-service
server.port=0

我試圖添加這些屬性但從未奏效

@SpringBootApplication(exclude = {
  MongoAutoConfiguration.class, 
  MongoDataAutoConfiguration.class
})

Answer 1

我建議您 -> 將 socketKeepAlive 設置為 true（在最新版本的本機驅動程序中默認為 true）-> 設置 maxConnectionIdleTime <.net.ipv4.tcp_keepalive_time 這樣您的 JVM 將獲得連接而不是反過來。

Answer 2

當我通過本地機器連接到 Atlas 集群時，我遇到了同樣的問題。 我不得不再次通過 Atlas 儀表板將我的 IP 地址列入白名單。

將您當前的 IP 地址列入您的 mongo 數據庫集群中的白名單
