直接上代码
public static void main(String[] args) {String str = null;try {Resource resource = new ClassPathResource("static/abc.txt");BufferedReader bReader = null;bReader = new BufferedReader(new InputStreamReader(resource.getInputStream()));StringBuffer sb = new StringBuffer();String s = "";while ((s = bReader.readLine()) != null) {//逐行读取文件内容，不读取换行符和末尾的空格sb.append(s + "\n");//将读取的字符串添加换行符后累加存放在缓存中}str = sb.toString();} catch (IOException e) {e.printStackTrace();}System.out.println(str);
}"static/abc.txt" 全路径是 D:\gitworkspace\project\src\main\resources\static\abc.txt
