springBoot日志系统，实现日志输出到文件中

Java实现日志输出到文件中

public void consoleLog() throws IOException {
        File file = new File("E:\\es.log");
        FileWriter fileWriter = null;
        if (!file.exists()) {
            file.createNewFile();
        }
        try {
            fileWriter = new FileWriter(file, true);
            for (int i = 0; i < 100; i++) {
                fileWriter.write("log: " + i + "\r\n");
            }
        }catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (fileWriter != null) {
                fileWriter.close();
            }
        }

    }
