java - Docker 中的 Postgres 服务器无法连接到 Spring Boot 应用程序

我在 docker 容器中有一个 postgres 数据库。我正在尝试让我的 Spring Boot 应用程序在容器外部连接到它。

我的docker-compose

  postgress-admin: #localhost:5050
container_name: postgress-admin
image: dpage/pgadmin4
restart: always
ports:
- "5050:80"
# volumes:
# - postgress-admin:/root/.pgadmin
environment:
PGADMIN_DEFAULT_EMAIL: pgadmin4@pgadmin.org
PGADMIN_DEFAULT_PASSWORD: admin
links:
- postgres
networks:
- your-network
postgres:
container_name: postgres_container
image: postgres
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: s$cret
# PGDATA: /data/postgres
# volumes:
# - postgres:/data/postgres
ports:
- "5432:5432"
networks:
- your-network
restart: unless-stopped

如果我运行 docker exec -it postgress_container psql -U postres -W我可以与 s$cret 连接。因此,看起来容器正在工作。

此外,我可以使用上面的撰写文件中的用户名和密码连接到 pgadmin,这样看起来就可以工作了。

我的应用程序:

package org.example.junk;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
public class JunkApplication {

public static void main(String[] args) {
SpringApplication.run(JunkApplication.class, args);
}

}

我的模型:

package org.example.junk.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import java.math.BigDecimal;

@Entity
public class Product {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long _id;
private String description;
private BigDecimal price;
private String imageUrl;

public Long getId() {
return _id;
}

public void setId(Long id) {
this._id = id;
}

public String getDescription() {
return description;
}

public void setDescription(String description) {
this.description = description;
}

public BigDecimal getPrice() {
return price;
}

public void setPrice(BigDecimal price) {
this.price = price;
}

public String getImageUrl() {
return imageUrl;
}

public void setImageUrl(String imageUrl) {
this.imageUrl = imageUrl;
}
}

我的存储库:

package org.example.junk.repository;

import org.example.junk.model.Product;
import org.springframework.data.repository.CrudRepository;

public interface ProductRepository extends CrudRepository<Product, Long> {
}

我的application.properties是

spring.datasource.hikari.connectionTimeout=20000
spring.datasource.hikari.maximumPoolSize=5

## PostgreSQL
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=s$cret

spring.datasource.driverClassName=org.postgresql.Driver
#drop n create table again, good for testing, comment this in production
spring.jpa.hibernate.ddl-auto=create
#spring.jpa.properties.hibernate.default_schema = schemaName

这是我遇到的错误

我的目标是尝试立即为数据库创建一个表。它不应该预先存在。但是,如果它确实存在,则不会覆盖它。我只是想让它启动并运行,这就是为什么我到目前为止还没有保存卷。

最佳答案

错误说hibernate.dialect为空

Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

application.properties中设置hibernate.dialect

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQL82Dialect 

对于 9.2 及更高版本,您应该使用 org.hibernate.dialect.PostgreSQL92Dialect 代替

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQL92Dialect

注意:从 here 中查找与您正在使用的 PostgreSQL JDBC 驱动程序最匹配的方言。
