java - 当我尝试连接 ht2 数据库时，找不到数据库“mem:”，并且 IFEXISTS=true

问题描述

我有具有 4 个微服务的基本 Spring Boot 应用程序。发现服务、Api 网关服务 (Zuul)、UsersMicorservise 和 Accounts 微服务

我正在尝试将 h2 内存数据库添加到我的用户服务中，但是当我加载 h2 控制台并按下连接时，我收到了此消息

在此处输入图像描述

这些是我的 application.properties

server.port=${PORT:0}
spring.application.name=users-ws
eureka.client.serviceUrl.defaultZone = http://localhost:8010/eureka
spring.devtools.restart.enabled = true
eureka.instance.instance-id=${spring.application.name}:${spring.application.instance_id:${random.value}}


# H2
spring.h2.console.enabled=true
spring.h2.console.settings.web-allow-others=true
spring.datasource.url=jdbc:h2:mem:test

这是我的 pom.xml

解决方案

spring.h2.console.enabled=true
spring.datasource.url=jdbc:h2:mem:test;IFEXISTS=FALSE;DB_CLOSE_DELAY=-1
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.h2.console.path=/h2-console

存在主义者

或者

降级到 1.3.170

 <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <version>1.3.170</version>
        <scope>runtime</scope>
    </dependency>
