java 根据路径读取txt文件的办法
根据txt文件路径，读取内容的方法:
1.txt文件在本地磁盘中存放：
public static void test1() {String path = "d:\\testfile.txt";File file = new File(path);try {BufferedReader rd = new BufferedReader(new FileReader(file));String str = "";String s = rd.readLine();while (null != s) {str += s + "<br/>";s = rd.readLine();}System.out.println(str);} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}} /**从数据库中读取txt文件--------------start------------------------**/String str = "";for(T_multimedia multimedia:list_multimedia){if(multimedia.getMulttype()==4){@SuppressWarnings("deprecation")String path = ServletActionContext.getRequest().getRealPath(multimedia.getMultpath()); //获取文本的绝对路径File file = new File(path);try {BufferedReader rd = new BufferedReader(new FileReader(file));String s = rd.readLine();while (null != s) {str += s;s = rd.readLine();}} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}}/**从数据库中读取txt文件--------------end------------------------**/setAttribute("str", str);//把文本内容存放到容器中， //利用el表达式在页面上显示文本内容
