Question

我一直在争取在我的系统上安装Spring 3.1（最新）和Hibernate JPA几天。我浏览了所有教程但未能修复它。我已经从Eclipse安装了Spring＆lt; em>安装新软件。我现在想要将Hibernate JPA添加到它并想要测试所有内容。

Answer 1

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，并帮助您创建基于Spring和hibernate的项目所需的所有脚手架。

希望有所帮助。

Answer 2

我遇到了同样的问题。我花了很多时间在Windows上安装STS作为Spring on Eclipse，就像使用tc服务器一样安装在Tomcat上。它没有用。我去了Ubuntu 10.04 LTS，现在我没有问题，就像STS一样，Eclipse和Spring一样有Tomcat

使用哪个IDE无关紧要。这是我的spring-dao.xml：
