将System.out输出在控制台的信息保存在文件中(未测试)

将当前项目的System.out的输出保存在当前项目下的system.out.txt中

           //1.获取项目的目录            Path path = Paths.get(".");            Path resolve = path.resolve("system.out.txt");            System.out.println(resolve.toAbsolutePath().normalize().toString());            //2. 设置            if (resolve !=null) {                //not the best way to debug                OutputStream output = new FileOutputStream(resolve.toAbsolutePath().normalize().toString());                PrintStream printOut = new PrintStream(output);                System.setOut(printOut);            }            //3.测试 system.out.txt中是否有该信息            System.out.println(resolve.toAbsolutePath().normalize().toString())
