Docker 中的 Postgres 服务器无法连接到 spring 启动应用程序

[英]Postgres Server in Docker cannot connect to spring boot application

问题描述

我在 docker 容器中有一个 postgres 数据库。 我试图让我的 spring 引导应用程序在容器外连接到它。

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 -WI 可以连接到 s$cret。 因此，看起来好像容器正在工作。

此外，我可以使用上述撰写文件中的用户名和密码连接到 pgadmin，这样似乎可以正常工作。

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 model：

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

这是我得到的错误

我的目标是尝试从 go 中创建数据库表。 它不应该事先存在。 但是，如果它确实存在，它不会覆盖它。 我只是想让它启动并运行，这就是我到目前为止没有保存音量的原因。

错误说hibernate.dialect是 null

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

在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，您应该改用org.hibernate.dialect.PostgreSQL92Dialect

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

注意：从此处找到您正在使用的 PostgreSQL JDBC 驱动程序的最佳匹配方言
