使用Spring Boot应用程序访问Postgres Docker容器

标签： spring postgresql docker

我正在运行docker postgres容器并创建了一个名为“ avatardb”的数据库。

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
e28d5a5524c0        postgres            "docker-entrypoint.sh"   59 minutes ago      Up About an hour    0.0.0.0:5432->5432/tcp   gracious_bartik

spring.datasource.url=jdbc:postgresql://gracious_bartik:5432/avatardb

当我尝试启动spring boot应用程序时，出现以下错误消息：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.exception.JDBCConnectionException: Unable to open JDBC Connection for DDL execution

Process finished with exit code 1

这是错误消息。当我仅使用“ mvn spring-boot：run”启动它时，以及使用docker image启动它时，都会出现此错误

使用以下命令启动容器：

docker run -d --restart=always --name api -p 8084:8084 marcelv93/avatar-service:latest
docker run -d --restart=always --name postgres -p 5432:5432 postgres

我想将两个应用程序都作为docker容器运行。有必要使用docker-compose吗？

当我在数据库URL中使用localhost时，出现以下错误消息：

org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

1 个答案:

答案 0 :(得分：1)

您确定提供了正确的数据库URL吗？

如果您使用默认网络设置在本地使用docker并且没有自定义主机，则数据库url应为：

spring.datasource.url=jdbc:postgresql://localhost:5432/avatardb
