Настройка Spring / JPA Hibernate на Eclipse

Question

Я несколько дней боролся за установку Spring 3.1 (последней версии) и Hibernate JPA на мою систему.Я прошел все уроки, но не смог их исправить.Я уже установил Spring из Eclipse Install New Software .Теперь я хочу добавить в него Hibernate JPA и протестировать все.

Answer 1

Если у вас есть возможность выбрать IDE, я бы порекомендовал посмотреть Spring Tool Suite (STS) .STS поставляется с предустановленным Spring.

Вы также можете проверить Spring Roo .Spring Roo дает вам толчок и помогает в создании всех необходимых вам лесов для проектов, основанных на Spring и hibernate.

Неважно, какую IDE вы используете. Это мой spring-dao.xml:

Answer 3

У меня были такие же проблемы.Я потратил много времени на установку в качестве STS в качестве Spring на Eclipse в Windows, как на tc-сервере, так и на Tomcat.Это не сработало.Я перешел на Ubuntu 10.04 LTS и теперь у меня нет проблем как с STS, так и с Eclipse с Spring, как с Tomcat
