PgAdmin无法连接PostgreSQL数据库：SCRAM认证未提供密码报错

已在PgAdmin中创建服务器及数据库，尝试创建无密码服务器失败，仅能使用application.yml中配置的密码，但Spring Boot应用仍无法连接数据库，报错信息：

org.postgresql.util.PSQLException: The server requested SCRAM-based authentication, but no password was provided

相关配置与代码 #

application.yml 配置内容

spring:
  datasource:
    url: jdbc:postgresql://localhost:5432/jwt_security
    username: postgres
    password: Zygimantas1
    driver-class-name: org.postgresql.Driver
  jpa:
    hibernate:
      ddl-auto: create-drop
    show-sql: false
    properties:
      hibernate:
        format_sql: true
    database: postgresql
    database-platform: org.hibernate.dialect.PostgreSQLDialect

User.java 实体类代码

package com.zygimantas.security.user;

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.Id;
import jakarta.persistence.Table;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data                       //生成getter和setter方法
@Builder                    //提供对象构建器
@NoArgsConstructor          //配合@Builder所需的无参构造
@AllArgsConstructor
@Entity
@Table(name = "_user")

public class User
{
    @Id
    @GeneratedValue
    private Integer id;
    private String firstname;
    private String lastname;
    private String email;
    private String password;
}

已尝试参考论坛方案、新建数据库等操作，问题仍未解决。
