我是spring mvc
和hibernate
的新手。爲了幫助我理解我遵循本教程http://viralpatel.net/blogs/spring3-mvc-hibernate-maven-tutorial-eclipse-example/ 我收到了這個錯誤org.hibernate.HibernateException:找不到當前線程的會話。我已經將事務管理器和@transaction包含在服務實現和dao中。請在下面找到Spring mvc + hibernate + maven
錯誤日誌中的錯誤和代碼片段:

請格式化代碼。您可以選擇多行,然後單擊{}按鈕以獲得格式化的部分。您也可以取出pom.xml文件,保留異常堆棧跟蹤的前8-10行。 – gkamal
