java将System.out.println的输出导出到文件中

直接看代码

1 public static void saveStreamToFile(String savePath,String input){

2       try {

3             //savePath like c:/log.txt

4             System.setOut(new PrintStream(new FileOutputStream(savePath)));

5             System.out.println(input);

6       } catch (FileNotFoundException e) {

7             e.printStackTrace();

8      }

9 }
