【问题讨论】：

->application.properties 文件：- server.port=8085 spring.datasource.url=jdbc:h2:~/test spring.datasource.driverClassName=org.h2.Driver spring.datasource.username =root spring.datasource.password=root spring.jpa.database-platform=org.hibernate.dialect.H2Dialect spring.jpa.show-sql=true spring.jpa.hibernate.ddl-auto=更新 spring.h2.console。 enabled=true spring.h2.console.path=/h2

【参考方案1】：

尝试删除数据库文件（test.mv.db 和 test.trace.db）。 也许您之前已经创建过它并为它使用了不同的凭据。

【讨论】：

是否可以读取由其他用户创建的 H2 备份？假设我想更新我现有的 H2 DB 密码。我还能读取使用旧凭据创建的备份吗？

【参考方案2】：

Faced similar issue. 
**Resolution (Worked for me)**:
[enter image description here][1]
 1. Remove and re-add Saved Setting and Setting Name (highlighted screen enclosed) 
    [Generic H2(Embedded)]
 2. Make sure JDBCURL, Username, Password match your application properties.
 3. Update Build and restart Spring Boot Application. 

另外，删除浏览器历史记录、缓存等，

**Sample Application. Properties**
    spring.h2.console.enabled=true
    spring.datasource.url=jdbc:h2:mem:dcbapp
    spring.datasource.driverClassName=org.h2.Driver
    spring.datasource.username=sa
    spring.datasource.password=password
    spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
