无法使用 docker 运行 Spring Boot 应用程序

Question

以下场景：

场景： 我在 Eclipse 上使用 Spring Boot 2 开发了一个微服务应用程序。该应用程序工作正常。现在我想用 docker 运行它。此外，图像必须与 mysql 数据库交互。为了构建 docker 镜像，我在 pom.xml 中使用了 com.spotify 插件。

    <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>

这会在我的目标文件夹中创建一个 docker 文件和 .jar 文件： Docker 文件：

FROM java:8

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

它会导致相同的堆栈跟踪。Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'customBasicAuthenticationFilter': Unsatisfied dependency expressed through field 'mobileUserController';
