无法通过 Spring Boot 连接到具有读取权限的 PostgreSQL 数据库中的表

问题描述 投票：0回答：1

任务如下 - 需要连接到对具有多个表的特定模式具有读取访问权限的现有数据库。我正在尝试连接到其中一张表（我重复一遍，仅读取访问权限）。该表包含大约 50 列。我的最终目标是简单地在某些 ArrayList 中显示该表的内容。

以下是我这个新手的问题：

是否有必要将表中存在的所有列注册到实体类中，还是只注册那些我感兴趣的列就足够了？ 为什么会出现下面列出的错误？需要做什么？

applications.properties：

#PostgresDB
spring.dt.datasource.jdbc-url=jdbc:postgresql://dbserver:5432/postgres?currentSchema=myschema
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.dt.datasource.driverClassName=org.postgresql.Driver
spring.dt.datasource.username=user
spring.dt.datasource.password=password
spring.dt.datasource.initialization-mode=always
spring.dt.datasource.initialize=true



spring.jpa.hibernate.ddl-auto = none
spring.servlet.multipart.enabled=true
spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.file-size-threshold=2KB
spring.servlet.multipart.max-request-size=10MB

实体：

package org.workproject.XLSX4.EntityDB2.models;

import jakarta.persistence.*;

@Entity
@Table
public class tbl_downtimes {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
Integer id;

@Column
String title;

String shortdescript;

String state;


public tbl_downtimes() {
}

public Integer getId() {
    return id;
}

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

public String getTitle() {
    return title;
}

public void setTitle(String title) {
    this.title = title;
}

public String getShortdescript() {
    return shortdescript;
}

public void setShortdescript(String shortdescript) {
    this.shortdescript = shortdescript;
}

public String getState() {
    return state;
}

错误：

是否有必要将表中存在的所有列注册到实体类中，还是只注册那些我感兴趣的列就足够了？

A：不需要，没有必要将表中存在的所有列都注册到JPA实体类中。您可以在应用程序中仅映射您感兴趣的列。 JPA 只会与您在实体类中定义的列进行交互。

现在对于错误，根据您共享的信息，似乎您需要禁用自动 ddl 生成： 

spring.jpa.hibernate.ddl-auto=none
