无法使用docker运行Spring Boot Application

Question

following scenario:

SCENARIO: I developed a Microservice Application with Spring Boot 2 on eclipse. The application works fine. Now I want to run it with docker. In addition, the Image has to interact with a mysql db. To build the docker image I use the com.spotify plugin in my pom.xml.

    <plugin>
      <groupId>com.spotify</groupId>
      <artifactId>docker-maven-plugin</artifactId>

      <configuration>
        <imageName>usermanagementservice</imageName>
        <baseImage>openjdk:8-jre-alpine</baseImage>
        <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
        <!-- copy the service's jar file from target into the root directory of the image --> 
        <resources>
           <resource>
             <targetPath>/</targetPath>
             <directory>${project.build.directory}</directory>
             <include>${project.build.finalName}.jar</include>
           </resource>
        </resources>
      </configuration>
    </plugin>

this create a docker file and the .jar file in my target folder: Docker file:

FROM java:8
ENTRYPOINT ["java", "-jar", "/UserManagementService-0.0.1-SNAPSHOT.jar"]

So now I want to run the project with docker compose:

> compose file: version: '2.1' services:   usermanagement-service:
>     image: usermanagementservice
>     restart: on-failure
>     ports:
>       - "7778:7778"
>     depends_on:
>       mysqldb:
>         condition: service_healthy
> 
>   mysqldb:
>     image: mysql
>     volumes:
>       - ./mysql-data:/var/lib/mysql
>       - ./mysql-init-files:/docker-entrypoint-initdb.d
>     restart: always
>     environment:
>       MYSQL_ROOT_PASSWORD: root
>       MYSQL_DATABASE: userdb
>       MYSQL_USER: testuser
>       MYSQL_PASSWORD: testuser
>     expose:
>       - "3306"
>     healthcheck:
>       test: ["CMD", "mysqladmin" ,"ping", "-h", "localhost"]
>       timeout: 3s
>       retries: 10

Expected behaviour The usermanagementservice should wait until my sql db is initialized and ready. Once this is done, the service should connect to it and start.

Problem: The part with the init mysql works but my usermanagementservice crashes on startup. I get a load of unsatisfied bean exceptions.

Attempts I followed some online tutorials with different Docker Files and so on. But nothing worked. I guess it might be a Problem ob the entry point because Beans are created before application startup as singletons. Is there any import in my dockerfile I have to add or any modification on the entrypoint? Thanks in advance

Answer 1

It causes the same stacktrace.

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'customBasicAuthenticationFilter': Unsatisfied dependency expressed through field 'mobileUserController'; nested exception is org.springframework.beans.factory.Unsat
