最近常搞 Jpa/Hibernate，但常發現如下的錯誤訊息：

org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: myerstone.dilas.core.entities.School.semesters, no session or session was closed

查過一些文獻後，將相關有用的參考資料整理於下，作為以後參考的依據：

• LazyInitializationException overcome
• Open Session in View
• JPA Implementation Patterns: Lazy Loading
• In Spring with jpa/hibernate, how do I keep a session open to avoid lazy initialization exceptions?
• hibernate: LazyInitializationException: could not initialize proxy
• Cause and solution of “org.hibernate.LazyInitializationException: could not initialize proxy – no Session” error
• Hibernate映射关系 no session or session was closed
