aspectj 处理异常问题

关于 java异常问题?
以前在学习时,老师说过要处<em>处理</em>异常,把所的异常都抓住,<em>处理</em>掉,不要在后出现一大堆错误,rn还有就是在测试时的 System.out.println();rn这样的语句都不要,说是占空间内存,rnrn 可是现在和我一起做项目的同事,他根本就没<em>处理</em>过异常, rn try rn rn  rn catch(Exception ex) rnrn   ex.printStackTrace(); rn rnrn就只有这段代码,每次出错误了,tomcat的黑窗下全是异常,rn如果一直这们不用 log.error把ex.printStackTrace(); rn换掉,再把异常<em>处理</em>后返回客户,会有什么问题,是占内存吗?rn还是会出其它问题?

Java异常问题小结
一、异常的分类在Java中,所有的异常都继承自Throwable,Throwable派生出来的子类有两种:Exception和Error。Error(错误):程序无法<em>处理</em>的错误。大部分是编写的Java代码无关,是Java虚拟机层面出现的问题,比如运行时Java虚拟机内存不足。出现Error时,Java虚拟机只能尽可能友好的终止当前进程。Exception(异常):程序可以<em>处理</em>的异常。Exceptio
