使用 Java 访问 MongoDB 时连接到服务器 localhost:27017 时监控线程出现异常

问题描述

在为 MongoDB 运行 Java 应用程序时出现以下异常:

I have the following exception when running Java app for MongoDB:

[localhost:27017] org.mongodb.driver.cluster : Exception in monitor thread while connecting to server localhost:27017 while accessing MongoDB with Java

调用栈如下:

这些名称都不属于我的应用程序.另外我在本地主机上没有 MONGODB 服务器.我正在使用远程主机并稍后设置它.在我关于 Mongo 的任何陈述之前发生异常.

Neither of these names belong to my application. Also I have NO MONGODB server on local host. I am using remote host and setting it later. An exception occurs BEFORE any of my statements concerning Mongo.

更新

这可能是一些 Spring 提供的 bean 访问 Mongo.如何禁用它们?

This is probably some Spring provided beans accessing Mongo. How to disable them?

我的配置包含以下依赖项:

My config contains following dependencies:

dependencies {
    compile('javax.media:jai_core:1.1.3')
    //compile('jai_core:1.1.3')

//  compile('org.springframework.boot:spring-boot-starter-data-mongodb')
    compile('org.mongodb:mongodb-driver:3.0.4')
    compile('org.mongodb:bson:3.0.4')

    compile('org.geotools:gt-api:14.2')
    compile('org.geotools:gt-shapefile:14.2')
    compile('org.geotools:gt-geometry:14.2')
    compile('org.geotools:gt-referencing:14.2')
    compile('org.geotools:gt-geojson:14.2')
    compile('org.geotools:gt-mongodb:14.2')

    compile('org.springframework.boot:spring-boot-starter-web')
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

即我已经删除了 org.springframework.boot:spring-boot-starter-data-mongodb 并且正在考虑自己使用 Mongo ...

i.e. I have removed org.springframework.boot:spring-boot-starter-data-mongodb and was thinking will use Mongo myself...

更新2

我发现了相关问题:如何禁用弹簧-data-mongodb 在 spring-boot 中自动配置

推荐答案

我要在我的主注释类中添加排除注释，

I was to add exclusion annotation to my main annotated class,

即而不是

@SpringBootApplication

我应该有

@SpringBootApplication
@EnableAutoConfiguration(exclude={MongoAutoConfiguration.class})
