Java:干净地将异常重定向到字符串
Java:干净地将异常重定向到字符串
提问于 2014-07-24 18:44:52
在Java中，有时我会得到一个异常解析用户输入。与其打印堆栈跟踪，我希望它“干净”地将输出重定向到字符串。示例(使用LuaJ)：
例外：
Exception in thread "Thread-3" org.luaj.vm2.LuaError: [string "jhkfchyufjhdnxvk,gh'bnmcvk,fvjmfk,xdcfsdkckucfdxfds,ie(); "]:1: unfinished string

您可以捕获异常并打印exception.getMessage()。
try {
... parsing code ...
}
catch (Exception exc) { // change this to catch the specific type of exceptions relevant to the parsing
System.out.println(exc.getMessage()); // or redirect the message to a file
