When an exception occurs, this code snippet will print the stack trace of the exception to a string. This way, the exception stack trace at runtime can be recorded in log file.
import java.io.PrintWriter;import java.io.StringWriter; public static String getStackTrace(Throwable t) { StringWriter sw = new StringWriter(); PrintWriter pw = new PrintWriter(sw, true); t.printStackTrace(pw); pw.flush(); sw.flush(); return sw.toString(); }
