md5加密用户登陆遇到的问题及解决办法
有个项目的登陆模块使用到了cas，应需求要求，用户名和密码传输时使用了md5加密模式，加密的密码可以直接保存在数据库，但是加密的用户名则必须解密出来才行，于是后台的java代码中便写了针对用户名的解密代码。
而前台，是在输完用户名和密码后，点击登陆按钮的时候调用相应的方法进行加密并发请求传输。
但是测试过程中却发现了一个问题，就是在有的时候输完用户名、密码和验证码以后回车，后台会报如下的数组下标越界的异常：
java.lang.ArrayIndexOutOfBoundsException: 5

debug之后发现了问题所在：
正常情况下，登陆时前台传递的用户名和密码应该是md5加密后的数据，但是在上面那种情况下传递的却并没有加密，在input中输入了什么，传递的依然还是什么。
这也就是说，回车之后根本就没有走md5加密数据的方法，因此，不是md5加密的，却用了md5加密的方式解密，程序便出现如上的异常。
最终的解决办法是在登陆界面的那些input中加上如下属性：
onkeypress="if(event.keyCode == 13) return false;"
也就是禁用了input上的enter键，在input上回车就不会再发请求到后台，也就不会再出现上述的问题。
