在Eclipse上配置Spring / JPA Hibernate

问题描述

| 我一直在努力在系统上安装Spring 3.1（最新）和Hibernate JPA。 我遍历了所有教程，但无法修复。 我已经从Eclipse的Install New Software安装了Spring。我现在想向其中添加Hibernate JPA，并要测试所有内容。     

解决方法

如果您可以选择IDE，那么我建议您查看Spring Tool Suite（STS）。 STS预装了Spring的东西。 您也可以查看Spring Roo。 Spring Roo为您提供了一个快速入门，并可以帮助您创建基于Spring和Hibernate的项目所需的所有支架。 希望能有所帮助。     ,我有同样的问题。我花了很多时间在Windows上的Eclipse上与Spring Server以及Tomcat一样，作为Spring的STS安装。它没有任何作用。我去过Ubuntu 10.04 LTS，现在像STS，Eclipse和Spring，Tomcat一样，都没有问题     ,使用哪个IDE都没有关系。这是我的spring-dao.xml：
