讀取文件為String 、訪問鏈接直接跳轉html
環境：SpringMVC 、前端jsp
InputStreamReader
FileInputStream fileInputStream = new FileInputStream(formatFile.getHtmlpath());InputStreamReader reader = new InputStreamReader(fileInputStream, StandardCharsets.UTF_8);char[] b = new char[1024];int cnt = 0;StringBuilder sb = new StringBuilder();while((cnt = reader.read(b,0,b.length)) != -1){sb.append(b.toString());}
結果：能讀取出來，不亂碼，但是字符中間多了逗號
BufferedReader
@RequestMapping("/xxx/yyy")public ResponseEntity<String> markReportHtml(@RequestParam(value = "id") Integer id) throws IOException {HttpHeaders httpHeaders = new HttpHeaders();httpHeaders.set("Content-Type","text/html;charset=UTF-8");F f = fDao.selectById(id);if(f == null || StringUtils.isEmpty(f.getHtmlpath())){return new ResponseEntity<>("<html><div>未查詢到數據</div></html>",httpHeaders, HttpStatus.CONFLICT);}StringBuilder sb = new StringBuilder();BufferedReader br=new BufferedReader(new InputStreamReader(Files.newInputStream(Paths.get(formatFile.getHtmlpath())), StandardCharsets.UTF_8));String line;while ((line = br.readLine())!=null) {sb.append(line);}return new ResponseEntity<>(sb.toString(), httpHeaders, HttpStatus.OK);}
結果：訪問接口，前端無需任何操作直接跳轉html頁面，符合要求
