web项目发布到Tomcat之后,如果tomcat是安装在比如
C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\****
那么你获取当前类的路径的时候,就会出现问题,因为它会报出%20
C:\Program%20Files\Apache%20Software%20Foundation\Tomcat 6.0\webapps\****
这个时候你再做一些关于文件的操作,程序就挂了,报一些未知错误,那么解决方案就是使用字符串的replace方法,进行字符串替换即可.
//获取当前类加载器,并找到指定目录POOLCONFIG_FOLDER是之前设置好的static 变量
String path = Thread.currentThread().getContextClassLoader().getResource(POOLCONFIG_FOLDER).getPath();
//进行字符串替换
path = path.replace("%20", " ");
