最新SpringMVC + spring3.1.1 + hibernate4.1.0 集成及常见问题总结

不是不支持，算是个bug。

具体见http://stackoverflow.com/questions/10852923/method-is-ambiguous-for-the-type-but-the-types-are-not-ambigues-and-the-error

总之很神经。

为什么不把spring security一起集成进去呢？

嗯，这个问题也困扰我一个晚上，看了一下你的链接解决了，
环境 win64 +eclipse4.2.1 +jdk1.6
解决方法 在eclipse.ini -vmargs后面添加  -DtolerateIllegalAmbiguousVarargsInvocation=true
重启eclipse，并clean一下项目 重新编译即可，希望对之前 好几个人问的同一个问题有解决办法，
当然要是 楼主能编辑一下 在自己的文章里就好了，看了博客和论坛的这个文章 至少有5个以上的人遇到了这个问题。

其实真有必要升级到hibernate4么？哪方面提升了？

有没有人能说说哪些方面值得升级到hibernate4.。。。

启动后项目报错

顺便问一下你这里好像没有配置OpenSessionInViewFilter
