从InputStream到servletInputStream

我有这个InputStream：

InputStream inputStream = new ByteArrayInputStream(myString.getBytes(StandardCharsets.UTF_8));

如何将其转换为ServletInputStream？

我努力了：

ServletInputStream  servletInputStream = (ServletInputStream) inputStream;

但不起作用。

我的方法是这样的：

private static class LowerCaseRequest extends HttpServletRequestWrapper {
        public LowerCaseRequest(final HttpServletRequest request) throws IOException, ServletException {
            super(request);
        }
        @Override
        public ServletInputStream getInputStream() throws IOException {
            ServletInputStream servletInputStream;
            StringBuilder jb = new StringBuilder();
            String line;
            String toLowerCase = "";
            BufferedReader reader = new BufferedReader(new InputStreamReader(super.getInputStream()));
            while ((line = reader.readLine()) != null) {
                toLowerCase = jb.append(line).toString().toLowerCase();
            }
            InputStream inputStream = new ByteArrayInputStream(toLowerCase.getBytes(StandardCharsets.UTF_8));
            servletInputStream = (ServletInputStream) inputStream;
            return servletInputStream;
        }
 }

我正在尝试将所有请求都转换为小写。

回答：

试试这个代码。

ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(myString.getBytes(StandardCharsets.UTF_8));
    ServletInputStream servletInputStream=new ServletInputStream(){
        public int read() throws IOException {
          return byteArrayInputStream.read();
        }
      }
