问题描述

我正在使用Spring Boot 3.4.0（Snapshot）、Maven、Java 22，搭配PostgreSQL数据库。以下是我的application.properties配置：

spring.application.name=api
spring.datasource.url = jdbc:postgresql://localhost:5432/my_database?verifyServerCertificate=false&useSSL=false&requireSSL=false
spring.datasource.username = root
spring.datasource.password = password
spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto=validate

运行项目时，看到如下日志信息（并非异常，只是信息展示异常）：

Database JDBC URL [Connecting through datasourcenull]
Database driver: undefined/unknown
Database version: 16.4
Autocommit mode: undefined/unknown
Isolation level: undefined/unknown
Minimum pool size: undefined/unknown
Maximum pool size: undefined/unknown

但项目其余功能均正常运行，完整启动日志如下：

我尝试修改了application.properties中的spring.jpa.hibernate.ddl-auto、spring.jpa.database-platform以及spring.datasource.driver-class-name配置，但问题依旧。请问这是什么原因导致的？

原因分析与解决办法

首先明确：这条日志不是异常，只是Hibernate日志输出逻辑的小问题，完全不影响数据库连接和项目功能——从启动日志能看到Hikari连接池已经成功初始化并获取了PostgreSQL连接，项目也正常启动了。

具体原因：

你使用的Hibernate 6.6.0.Final（Spring Boot 3.4.0-SNAPSHOT默认依赖版本）在通过Spring提供的Hikari数据源获取连接时，日志模块无法正确从数据源中提取URL、驱动、连接池参数等信息，导致输出undefined/unknown这类占位内容。
日志里的Connecting through datasourcenull是字符串拼接错误，实际数据源是正常的，只是日志输出时没正确填充数据源名称。

解决建议：

如果你只是在意日志美观，完全不用修改，项目功能不受影响，这只是日志展示的小bug。
可以等待Spring Boot 3.4.0正式版，或者手动升级Hibernate到后续修复版本，官方大概率会解决这个日志输出问题。
同时按照日志提示，去掉spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect配置，Hibernate 6+会自动识别PostgreSQL方言，手动配置反而会触发废弃警告。
