Question

这是我第一次将MongoDB与Spring结合使用，我想做的就是启动Spring服务器，但是连接打开后会立即关闭。

环顾类似的场景后，有人提出了删除Spring Data JPA依赖项的建议，我没有但没有帮助。另一个建议是说要添加h2作为依赖项，因为Spring Starter在做一些事情之前就需要它，这确实有所帮助，因为以前的连接甚至都没有打开。我还编辑了属性文件，但似乎没有任何效果。

成绩文件：

group = 'com.danielturato'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
    implementation 'org.springframework.boot:spring-boot-starter-mail'
    implementation 'org.springframework.boot:spring-boot-starter-security'
    runtimeOnly 'com.h2database:h2'
    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'org.springframework.security:spring-security-test'
}

application.properties：

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=mongo
server.port=8095
