英文:
Getting connection errors to in-memory neo4j instance during testing using the new spring-data-neo4j 6.0.0-SNAPSHOT
问题
使用发布版本，此应用程序代码正常工作。然而，切换到更新的快照版本后，我现在遇到异常。
异常消息让我认为需要更改配置以使我的测试用例再次工作，但是我无论如何都无法弄清楚它们需要什么。
任何帮助将不胜感激。

我的测试用例使用了注解：
- @SpringBootTest
- @EnableAutoConfiguration
- @AutoConfigureDataNeo4j
Caused by: org.springframework.dao.PermissionDeniedDataAccessException: 不支持的身份验证令牌，仅当禁用身份验证时才允许使用方案 'none'; 错误代码 'Neo.ClientError.Security.Unauthorized'

...
在一些测试变体中，我得到：
“请注意，Neo4j 4.0 中默认的加密设置已更改”。
英文:
Using the release versions, this application code works. However, switching to the newer snapshots, I am now getting exceptions.
The exception messages lead me to think a config change is needed to get my test cases working again, but for the life of me I cannot figure out what they would need to be.
Any help would be appreciated.

In some variations of my testing, I get:
"Note that the default encryption setting has changed in Neo4j 4.0"

以下是翻译好的内容：
你的应用程序属性是什么？
SDN6的语法已更改，但可能尚未更新到文档中。
参见：
嗯，实际上在自述文件中有（但尚未在文档中更新）：
https://github.com/spring-projects/spring-data-neo4j
还有在引导文档中：
英文:
What are your application properties?
The syntax changed for SDN6, but might not have made it into the docs
See:
ah it actually has it in the readme (but not yet in the docs):
https://github.com/spring-projects/spring-data-neo4j
Also in the boot docs:
