本文分享了一个JSF+Spring+Hibernate整合的实战案例，详细介绍了如何搭建开发环境并解决常见问题。
本人以前是学Struts的,最近转投JSF的怀抱.做了一个JSF+Spring+Hibernate的例子,绝对能跑起来.(网上好多都是跑不起来的).想去做这样的一个实例,我相信你已经具备了这些知识了,在此我就不论述这些了 .
我的开发环境是 eclipse3.2+myeclipse5.1(包含hibernate3.1,spring1.2,SUN RI JSF1.1)+sqlserver2005
我在调试这个功能的时候,有两个地方出错.找了很就才解决的.我想很都朋友都遇到过这样的问题.一个就是applicationContext.xml 的数据源的配置问题,我用的是sqlserver2005,请注意它的连接URL. 还有一个很重要的错误就是项目做好了,发布到Tomcat的时候,提示是发布成功了,但TOMCAT就是不能它这个项目启动起来,原因是TOMACAT在启动你的项目的时候,不光加载你的WEB.XML文件,它也会加载你的applicationContext.xml文件的信息,如果的applicationContext.xml文件有错误如DATASOURCE配置错误,就会使tomcat无法启动你的项目.
这些都是血的教训,我想写出来就是不想再见到有人在出现这样的问题.因为这样的过程真的很痛苦的.! 我找错误的那两天真的很痛苦!!!!!!!!!!!!!!!!!!!!!!!
代码如下:
