java按行读取文件

按行读取一个文件内容的方法 (ps：始终记不住读取步骤，so这次记录到博客中)

public  List<String> readFileByLines(File file) throws IOException {List<String> list = new ArrayList<String>();BufferedReader reader = null;try {reader = new BufferedReader(new FileReader(file));String tempString = null;while ((tempString = reader.readLine()) != null) {list.add(tempString.trim());}} catch (IOException e) {log.error("readFileByLines", e);} finally {if (reader != null) {     reader.close();}}return list;}
