在Eclipse上配置Spring/JPA Hibernate

Question

我一直在爲我的系統安裝Spring 3.1（最新版）和Hibernate JPA而戰鬥。 我經歷了所有的教程，但一直無法解決它。 我已經從Eclipse的上安裝了Spring安裝新軟件。我現在想將Hibernate JPA添加到它並想測試一切。

Answer 1

如果您可以選擇IDE，那麼我建議您查看Spring Tool Suite (STS)。 STS預裝了Spring的東西。

您還可以退房Spring Roo。 Spring Roo爲您提供了一個快速入門，並幫助您創建基於Spring和休眠的項目所需的所有腳手架。

希望有所幫助。

Answer 2

我有同樣的問題。我花了很多時間在Windows上像Eclipse上的Spring一樣安裝STS，就像使用Tomcat的tc服務器一樣。它沒有工作。我去了Ubuntu 10.04 LTS，現在我沒有STS那樣的問題，就像Tom和Eclipse一樣，如Tomcat
