Java：干净地将异常重定向到字符串

在Java中，有时在解析用户输入时会出现异常。我希望它“干净地”将输出重定向到字符串，而不是打印堆栈跟踪。示例（使用LuaJ）：

例外情况：

Exception in thread "Thread-3" org.luaj.vm2.LuaError: [string "jhkfchyufjhdnxvk,gh'bnmcvk,fvjmfk,xdcfsdkckucfdxfds,ie(); "]:1: unfinished string
    at org.luaj.vm2.compiler.LexState.lexerror(Unknown Source)
    at org.luaj.vm2.compiler.LexState.read_string(Unknown Source)
    at org.luaj.vm2.compiler.LexState.llex(Unknown Source)
    at org.luaj.vm2.compiler.LexState.next(Unknown Source)
    at org.luaj.vm2.compiler.LexState.str_checkname(Unknown Source)

    at org.luaj.vm2.compiler.LuaC.compile(Unknown Source)

    at org.luaj.vm2.Globals.load(Unknown Source)
    at net.snugglesstuff.LeoBot.LuaThread.run(LuaThread.java:25)

输出应该是什么：

[string "jhkfchyufjhdnxvk,gh'bnmcvk,fvjmfk,xdcfsdkckucfdxfds,ie(); "]:1: unfinished string

您可以捕获异常并打印

exception.getMessage（）

谢谢！我会试试的。请注意，您可以，例如，将异常堆栈跟踪写入日志文件，以防您以后需要查看。谢谢！我会试试的。注意，你可以，例如，将异常堆栈跟踪写入日志文件，以备以后可能需要查看。使用log4j获取错误使用log4j获取错误

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
