关于javaMail发邮件途中网络中断应该怎么处理,求高手解决!

Question

如题,求高手指点,小弟想尽办法捕获各种异常还是会报com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error和连接到主机tcp/ip已中断异常,我想做到如果发邮件途中网线被拔掉了给个友好页面提示一下,而不是页面一堆报错信息!

Answer 1

我不管捕获Exception或SQLServerException异常,给了错误提示信息,但页面还是会报一堆错误信息!

Answer 2

 在catch块中可以进行代码处理。可以在里面return一个指定的值 或者是 在方法里面建集合当有异常时往集合中添加错误信息。然后把错误信息传到页面中  比如说STRUTS的国际化 EL表达式

Answer 3

代码放在tryCatch里,后台跟踪进了catch,页面有自定义的错误提示信息,return不管到本页面还是另外的页面,页面都会有一堆java的报错信息!

捕获到这个异常就知道是终端了，在catch中再做提示处理
