学习Spring的小记。。

      今天第一天写博客，应该是带着高兴的心情，因为我开始对spring入门了。。。也很想把我的好的感想写下来，也要把自己学习时遇到的问题，然后解决了问题的过程写下来。。。呵呵，，，当然，对java的心情自己一定也会在以后慢慢的道来 ：）晚上接着写。。。呵呵...

     spring的方便，强大真的让人咋舌。。。但是今天调了了好久的最简单的hello word的spring 程序 竟然一直报错，天哪，我说这spring 真的如此可怕吗？？？我觉得在此真的值得把我的错误打出来。。。。

     看了这个错误，真的让我头痛，，，但是真的这回感到绝对的功夫不负有心人，原来是我的setter方法名称写错了，，，再次写在这里，也不仅是让大家知道这个常识，其实更重要的是让自己能够记住，增长自己的经验。。。
