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());
