我刚下课，是初次用Ecplise，难道是我配置的问题？
我现在又运行一次，结果又出现了：Source not found for ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 307

lz点什么时候，出的error啊，我跑你的code，并没有出现你说的error,可是，奇怪的是，点个link到GetMessage 的时候，没有出现页面，而是出现了下载对话框，出现它倒是合理，但感觉，不出现也合理啊，我迷糊了

好像是类中无改方法，最好是贴出源码看看，经验不多。

我看了你的程序，本想给调试下，可是看了下，你只给核心的代码，无法给你调试。
上面的代码没异常的地方，估计看看是不是其他的代码错了
Source not found for ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 307
应该是过滤器代码有错误
