Bit records

本文介绍了如何调整Eclipse插件EasyExplore的设置以实现打开目录而非文件的功能,并分享了一个关于Log4j配置冲突导致程序错误的问题及解决方案。

用eclipse插件easyexplore的时候,打开 文件的时候,总是会打开对应的文件而不是相应的目录,今天搜了一下,发现只要改一个参数就可以了。 eclipse->window->preferences->easy explore 把参数explorer.exe{0}改为explorer.exe /select,{0} (参考了网上的资料,源地址http://blog.youkuaiyun.com/xzknet/article/details/4627713

 

 最近有一天,早上起来后,发现程序突然报错,log system找不到吧,大概是这个意思,仔细看信息是发现有两个 log4j的包,原来是在 pom.xml 中 <test></test>中引入的包有冲突。但是很奇怪,没有改任何代码,不知道为什么以前不报这个错,突然有一天就报了。
