Did you create a class or interface for MemberRepository?

에러부분이 나서 진행이 안되네요... 의존성 문제인거 같기도한데

We normally never include any built files - jar, war - in the source code repository like GitHub.&nbsp;Instead, we have a separate repository (e.g. Nexus) where the jar file is uploaded, so projects can just declare the dependency (e.g. pom.xml for maven) to download it.

When browser closes, the session id set in the ‘browser cookie’ is removed. It does not mean that session in the server is removed. However, after the certain amount of time, the session in the server will be also deleted as it wont be called anymore and hit the session max lifetime.

Though I need more context to oroperly tackle this question, it is highly likely that orderSearch condition is set in a way query does not return the orders. Please check what is set and what is supposed to set in the orderSearch parameter.
