问题描述

com.mongodb.MongoSocketOpenException: Exception opening socket

我的代码:
gradle.build

My code:
gradle.build

 testImplementation "org.testcontainers:spock:1.14.3"
 testImplementation "org.testcontainers:mongodb:1.14.3"

application.properties

application.properties

spring.data.mongodb.uri=mongodb://127.0.0.1:27017/test

测试

@Testcontainers
class TestContainersExample extends IntegrationSpec {
    @Shared
    MongoDBContainer mongoDb = new MongoDBContainer()

    def "setup"() {
        mongoDb.start()

        mongoDb.waitingFor(Wait.forListeningPort()
                .withStartupTimeout(Duration.ofSeconds(180L)));
    }


//test case
}
  

推荐答案

Testcontainer会将MongoDB服务器端口映射到您计算机上的随机端口.这就是为什么您不能在属性文件中对spring.data.mongodb.uri=mongodb://127.0.0.1:27017/test进行硬编码的原因.

Testcontainers will map the MongoDB server port to a random port on your machine. That's why you can't hardcode spring.data.mongodb.uri=mongodb://127.0.0.1:27017/test in your property file.

使用JUnit 5和Spring Boot> = 2.2.6的基本设置如下所示

A basic setup with JUnit 5 and Spring Boot >= 2.2.6 can look like the following

@Testcontainers
public class MongoDbIT {

  @Container
  public static MongoDBContainer mongoDBContainer = new MongoDBContainer();

  @DynamicPropertySource
  static void mongoDbProperties(DynamicPropertyRegistry registry) {
    registry.add("spring.data.mongodb.uri", mongoDBContainer::getReplicaSetUrl);
  }


}

如果您使用其他版本的JUnit或Spring Boot，请查看以下

If you are using a different JUnit or Spring Boot version, take a look at the following guide for the correct Testcontainers setup.
