如何将printStackTrace存储到字符串中 [英] How to store printStackTrace into a string

问题描述

如何获取 e.printStackTrace()并将其存储到 String 变量中?我想稍后在程序中使用 e.printStackTrace()生成的字符串.

How can I get the e.printStackTrace() and store it into a String variable? I want to use the string generated by e.printStackTrace() later in my program.

我还是Java的新手，所以我对 StringWriter 不太熟悉将是解决方案.或者，如果您有其他任何想法，请告诉我.谢谢

I'm still new to Java so I'm not too familiar with StringWriter that I think will be the solution. Or if you have any other ideas please let me know. Thanks

推荐答案

类似

StringWriter errors = new StringWriter();
ex.printStackTrace(new PrintWriter(errors));
return errors.toString();

应该成为您所需要的.
