Caused by: java.util.zip.ZipException: error in opening zip file异常的解决

tomcat 启动后，控制台打印了如下信息：

这还是我头一回遇到这种异常，从异常信息来看，应该是跟jar有关系，联想到最近刚对项目进行了升级，引入了几个新的jar包，问题会不会就出现了这几个新引入的jar包呢？，首先想到的是会不会jar引得不全，导致引用环节出了问题？逐个去排查，该引入的jar包都引入了，那是哪里出了问题呢？我又想到会不会新引入的jar包跟之前的jar的版本有冲突啊？当然，我马上否定了这种猜测，因为在升级到服务器之前，我在我的电脑测试了一遍，一切都OK啊，jar包都一样的，没报这个异常，后来上网搜了下，发现大多数网友的情形跟我的都不大一样，我的目光投向异常开始的JarResource，想想也只能是jar出的问题。于是我去比对原来的jar包和引入到服务器的jar，果然，发现服务器有个jar跟我原来的jar不太一致，我电脑上的iText-2.0.8 jar的大小是1M多,而服务器上的iText-2.0.8 jar却是6M多，同样一个jar，为什么引入的jar包比原先的大那么多？思来想去，我还是觉得导入jar的环节出的问题，导入jar进行到一半的时候，网络出现了点问题，说不上断网，是卡顿了好一会。我猜应该是这里导致的，当然这也只是我的猜测，技术大牛们如果知道，欢迎指出来。
最后我把本地相对应的jar导入服务器替换原来的，重启后，异常不再报，服务器正常运行起来了。
