Docker中的SpringBoot未连接到Mongo并引发异常

Question

我有三个微服务和三个数据库，例如 player-db、game-db 和 score-db。 对于这些服务中的每一个，我在它们的文件夹中定义了 Dockerfile。 （DockerFiles 相同，只是 JAR 文件的名称和 container_name 不同） 用于评分服务的 DockerFile：

 FROM openjdk:8
COPY ./target/demo-0.0.1-SNAPSHOT.jar score.jar
EXPOSE 8080
ENTRYPOINT ["java","-Dspring.data.mongodb.uri=mongodb://score-container-db:27017/","-jar","-Djava.rmi.server.hostname=127.0.0.1", "score.jar"]

我必须指出，我所有的服务包都是子包：

package spring.multiple.mongo.project;

这是我的应用程序，顺便说一下，在我使用的应用程序中 @SpringBootApplication(排除 = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class}) 用于自动配置。 我的申请：

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
//@EnableAutoConfiguration(exclude={MongoAutoConfiguration.class})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

这是我的 docker-compose.yml：

    version: "3"
services:
    player-docker:
        build:
            context: ./
            dockerfile: ./src/main/java/spring/multiple/mongo/project/player/DockerFile
        restart: always
        ports:
            - 8081:8080

        ports:

        depends_on:

    score-docker:
        build:

        restart: always
        ports:
            - 8083:8080
        depends_on:
            - db2 
    db:
        image: mongo
        container_name: player-container-db
        volumes:
            - mongodata:/data/db
        ports:
            - 27017:27017
        restart: always
        environment:
            MONGO_INITDB_ROOT_DATABASE: player-mongo-db
    db1:
        image: mongo
        container_name: game-container-db
        volumes:
            - mongodata:/data/db1
        ports:
            - 27018:27017
        restart: always
        environment:
            MONGO_INITDB_ROOT_DATABASE: game-mongo-db
    db2:
        image: mongo
        container_name: score-container-db
        volumes:
            - mongodata:/data/db2
        ports:
            - 27019:27017
        restart: always
        environment: 
            MONGO_INITDB_ROOT_DATABASE: score-mongo-db
volumes:
    mongodata:

我的 application.properties：

    spring.data.mongodb.host=localhost
spring.data.mongodb.database=player-db
spring.data.mongodb.port=27017
spring.data1.mongodb.host=localhost
spring.data1.mongodb.database=game-db
spring.data1.mongodb.port=27017
spring.data2.mongodb.host=localhost
spring.data2.mongodb.database=score-db
spring.data2.mongodb.port=27017

问题是，当我运行 docker-compose up 时，当启动 SpringBoot 部分时，对于我的所有服务，它都会显示一个错误：

在邮递员中：

Error: connect ECONNREFUSED 192.168.99.100:8080

我尝试了太多东西，我阅读了太多文档，但我找不到任何解决方案。 另外，我是 Docker 的初学者。 另外，我尝试 set spring.data.mongo.host = "To the service name in docker compose" 并将 spring.data.mongo.port = " 设置为服务端口"，如：

 spring.data.mongodb.host=player-container-db
spring.data.mongodb.database=player-db
spring.data.mongodb.port=27017
spring.data1.mongodb.host=game-container-db
spring.data1.mongodb.database=game-db
spring.data1.mongodb.port=27018
spring.data2.mongodb.host=score-container-db
spring.data2.mongodb.database=score-db
spring.data2.mongodb.port=27019

但没有任何改变，我和以前一样有错误。！

Answer 1

您是否尝试将 mongo 连接 uri 设置为 mongodb://<docker-container-name>:<port>？例如，在播放器 docker 中，您的 uri 将是 mongodb://player-docker:27017。

Answer 2

问题出在一些事情上： 1-我忘记了每次对我的应用程序进行一些更改时，我必须重建 JAR 文件。 2-我所有数据库的卷都是相同的，它导致了过度写入，因为这个 mongo 找不到其他（数据库），所以对于每个我使用不同的卷
