Question

虽然我正在使用spring-boot-starter-data-mongodb。我总是有超时异常。日志详细信息如下：

有人能告诉我为什么我总是超时吗？非常感谢。

我的application.yml是，春季启动版本是2.0.8.RELEASE，以下是内容：

spring:
  data:
    mongodb:
      host: 192.168.0.101
      port: 27017
      username: test
      password: test
      database: test
server:
  port: 8888
management:
  health:
    mongo:
      enabled: false

Answer 1

这不是最终解决方案，但是您可以尝试更长的超时时间。

 # The time to wait to establish a connection before timing out, in seconds.
 # (default: 10)
  connect_timeout: 99

如果在更改超时后成功连接，您应该找出建立连接并尝试修复它花费这么长时间的原因。如果即使在设置很长的超时后仍无法连接，您也应该检查代理并尝试ping mongodb所在的计算机。

Answer 2

您可以尝试以下方法：

<dependency>
    <groupId>com.spring4all</groupId>
    <artifactId>mongodb-plus-spring-boot-starter</artifactId>
    <version>1.0.0.RELEASE</version>
</dependency>

@EnableMongoPlus
@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

比你还有更多的配置属性可以玩：）

spring.data.mongodb.option.min-connection-per-host=0
spring.data.mongodb.option.max-connection-per-host=100
spring.data.mongodb.option.threads-allowed-to-block-for-connection-multiplier=5
spring.data.mongodb.option.server-selection-timeout=30000
spring.data.mongodb.option.max-wait-time=120000
spring.data.mongodb.option.max-connection-idle-time=0
spring.data.mongodb.option.max-connection-life-time=0
spring.data.mongodb.option.connect-timeout=10000
spring.data.mongodb.option.socket-timeout=0

spring.data.mongodb.option.socket-keep-alive=false
spring.data.mongodb.option.ssl-enabled=false
spring.data.mongodb.option.ssl-invalid-host-name-allowed=false
spring.data.mongodb.option.always-use-m-beans=false

spring.data.mongodb.option.heartbeat-socket-timeout=20000
spring.data.mongodb.option.heartbeat-connect-timeout=20000
spring.data.mongodb.option.min-heartbeat-frequency=500
spring.data.mongodb.option.heartbeat-frequency=10000
spring.data.mongodb.option.local-threshold=15

我还没有尝试过...但是也许值得一试。

或者在仓库中查看如何在不依赖项目的情况下做到这一点；）
