我在Spring引导项目中使用H2作为内存数据库进行单元测试。但是我得到了以下错误
if keyword:
keywords_found = re.findall(keyword, content_item)
keyword_number = len(keywords_found)
else:
keyword_number = 0
按配置如下

这是一个很老的问题，但我刚刚在 2021 年遇到了同样的问题。我设法解决了这个问题，只是将 DB_CLOSE_DELAY=-1 添加到记录的连接字符串 here：
这是我的 application.yaml：
spring:
flyway:
url: jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1
baseline-on-migrate: true
user: sa
password:
答案 1 :(得分：0)
尝试在测试 .properties 中设置飞行路线的数据库URL：
spring.datasource.url = jdbc:h2:mem:DBNAME
spring.datasource.username = sa
spring.flyway.url = jdbc:h2:mem:DBNAME
spring.flyway.baseline-on-migrate = true
