我正在使用Spring Boot和Postgres开发一个微服务应用程序.使用Docker,一个容器中的REST API和另一个容器中的Postgres,一切正常.但是当我尝试使用Kubernetes运行它时,它总是会出现API错误.

将Dockerfile在我的基于锁扣的弹簧API定义如下所示:

FROM alpine
RUN apk add openjdk8
MAINTAINER rjdesenvolvimento.com
COPY target/apipessoas-0.0.1.jar /opt/gaia/apipessoas.jar
ENTRYPOINT ["/usr/bin/java"]
CMD ["-jar", "/opt/gaia/apipessoas.jar"]
EXPOSE 8080

在DockerfilePostgres的:

FROM postgres:10-alpine
MAINTAINER rjdesenvolvimento.com
ENV POSTGRES_PASSWORD=postgres
ENV POSTGRES_PORT=5432
CMD ["postgres"]
ADD postgres.sql /docker-entrypoint-initdb.d/
EXPOSE 5432

我的docker-compose档案:

version: "3.0"
services:
  postgres:
    build:
      dockerfile: postgres.dockerfile
      context: .
    image: rjdesenvolvimento/postgres-apipessoas
    container_name: postgres
    ports:
      - "5432:5432"
    volumes:
      - /home/rodrigo/Projetos/Volumes:/var/lib/postgresql/data
    networks:
      - gaia_network

  apipessoas:
    build:
      dockerfile: api-pessoa.dockerfile
      context: .
    image: rjdesenvolvimento/api-pessoas
    container_name: api_pessoas
    ports:
      - "8080:8080" …

当我尝试使用 gradle 和 jdk 11 创建 jar 构建时，总是出现以下错误：

10:53:41: Executing task 'build'...

> Task :compileJava UP-TO-DATE
> Task :processResources UP-TO-DATE

我有一个问题，我找不到解决方案。我有一个 Book 表和一个 Author 表，具有多对多的关系。Book 表在 book 模式中，Author 表在 person 模式中。所以我有这个：

书本

人.作者

我做了以下代码：

*** Entity Book ***
@ManyToMany(mappedBy = "book")
private List<Author> author = new ArrayList<>();

和

*** Entity Author ***
@ManyToMany
@JoinTable(schema = "join_tables", name = "book_author", joinColumns = @JoinColumn(name = "fk_author"), inverseJoinColumns = @JoinColumn(name = "fk_book"))
private List<Book> books = new ArrayList<>();

我可以注册一本书有几个作者，一个作者有几本书。我可以在已注册的书中插入作者。向已注册的作者插入一本书。但我无法消除一本书与作者的关系。我试图做的事情：

@Repository
public interface AuthorRepository extends JpaRepository<Author, Long> {

    @Query("DELETE FROM join_tables.book_author jtba  WHERE  jtba.fk_author = :fka AND jtba.fk_book = :fkb")
    void deleteRelationshipBookAuthor(@Param("fka") Long fka, …
