使用Java访问MongoDB时连接到服务器localhost:27017时监视器线程中的异常

Question

在为MongoDB运行Java应用程序时,我有以下异常:

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

调用堆栈如下:

com.mongodb.MongoSocketOpenException: Exception opening socket

这两个名字都不属于我的申请.我在本地主机上也没有MONGODB服务器.我正在使用远程主机并稍后进行设置.关于Mongo的任何陈述之前都会发生异常.

UPDATE

这可能是一些Spring提供的bean访问Mongo.如何禁用它们？

我的配置包含以下依赖项:

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org.springframework.boot:spring-boot-starter-data-mongodb并且正在考虑将使用Mongo自己...

UPDATE2

我发现了相关的问题:如何在spring-boot中禁用spring-data-mongodb autoconfiguration

Answer 1

我是要在我的主要注释类中添加排除注释,

即代替

@SpringBootApplication

我应该

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

Answer 2

Try adding

spring.data.mongodb.host=hostIpOnWhichMongoIsRunning
spring.data.mongodb.port=27017

into application.properties.

If Mongo is not running on localhost, this should fix the issue.

Answer 3

我的想法建议我这样做。

@SpringBootApplication(exclude = {MongoAutoConfiguration.class})
