我已经容器化了一个 Spring Boot 应用程序。它包含在一个 jar 文件中。当我单独调用 jar 文件时它正在工作但是当我通过docker-compose up运行它时它会产生以下错误:
ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'crawlerController': Unsatisfied dependency expressed through field 'campaignservice'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'campaignService': Unsatisfied dependency expressed through field 'campaignrepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'campaignRepository': Cannot resolve reference to bean 'org.springframework.data.neo4j.transaction.SharedSessionCreator#0' while setting bean property 'session'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.data.neo4j.transaction.SharedSessionCreator#0': Cannot resolve reference to bean 'sessionFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [org/springframework/boot/autoconfigure/data/neo4j/Neo4jDataAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.neo4j.ogm.session.SessionFactory]: Factory method 'sessionFactory' threw exception; nested exception is java.lang.TypeNotPresentException: Type javafx.util.Pair not present
鉴于该 jar 在单独调用时可以工作，我假设所有依赖项都包含在类路径中。所以我不明白为什么它在通过Docker调用时不起作用
dockerFile 是:
FROM openjdk:8-jre
VOLUME /tmp
ADD target/SpringNeoServer.jar /SpringNeoServer.jar
EXPOSE 7864
ENTRYPOINT ["java", "-jar", "SpringNeoServer.jar"]
最佳答案
此版本的 openjdk 中不包含 JavaFX。
