无法通过Springboot连接到远程MongoDB

我试图连接到一个远程的MongoDB。 由于我没有得到一个MongoOpenSocketException，我认为已经建立了一个连接，但需要更多的启动应用程序。 我错过了什么？

Application.kt

package hello import org.springframework.boot.SpringApplication import org.springframework.boot.autoconfigure.EnableAutoConfiguration import org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration import org.springframework.context.annotation.Configuration /** * The main entry point to the application */ @EnableAutoConfiguration(exclude = arrayOf(MongoAutoConfiguration::class)) @Configuration class Application /** * Run the application * @param args The command line arguments */ fun main(args: Array) { SpringApplication.run(Application::class.java, *args) } 

的build.gradle：

 // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { ext.kotlin_version = '1.1.2-4' repositories { mavenCentral() } dependencies { // Needed for the 'kotlin' plugin classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" // Needed for the 'org.springframework.boot' plugin classpath "org.springframework.boot:spring-boot-gradle-plugin:1.5.2.RELEASE" // Needed for the 'kotlin-spring' plugin classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlin_version" } } // Allows us to compile Kotlin files apply plugin: 'kotlin' // Does some extra work to set up Spring Boot. // Specifically this gives us the "bootRun" task we will be using apply plugin: 'org.springframework.boot' // Allows for improved interop between Kotlin and Spring apply plugin: 'kotlin-spring' repositories { mavenCentral() } dependencies { // MongoDB compile "org.springframework.boot:spring-boot-starter-data-mongodb" // Kotlin Dependencies compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version" testCompile "org.jetbrains.kotlin:kotlin-test-junit:$kotlin_version" // Spring Dependencies compile("org.springframework.boot:spring-boot-starter-web") { exclude module: "spring-boot-starter-tomcat" } compile "org.springframework.boot:spring-boot-starter-jetty" compile "org.springframework.boot:spring-boot-starter-actuator" // Jackson Dependencies compile "com.fasterxml.jackson.core:jackson-annotations" compile "com.fasterxml.jackson.core:jackson-core" compile "com.fasterxml.jackson.core:jackson-databind" runtime "com.fasterxml.jackson.datatype:jackson-datatype-jdk8" runtime "com.fasterxml.jackson.datatype:jackson-datatype-jsr310" runtime "com.fasterxml.jackson.module:jackson-module-kotlin" } task wrapper(type: Wrapper) { gradleVersion = "3.5" } 

application.properties：

 spring.data.mongodb.host=asdf spring.data.mongodb.port=27017 spring.data.mongodb.database=asdf spring.data.mongodb.username=asdf spring.data.mongodb.password=asdf spring.data.mongodb.ssl.enabled=true 

主要错误：

 Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creatin g bean with name 'mongoDbFactory' defined in class path resource [org/springframework/boot/autoconfigure/data/mongo/MongoDataAutoConfiguration.class]: Unsatisfied dependency expressed through method 'mongoDbFactory' parameter 0; nested exception is org.springfr amework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.mongodb.MongoClient' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
