request.getInputStream() 只能读一次的解决方法

我们知道request.getInputStream()只能读一次，如果下一次读，就会报告Stream closed的错误。下面是解决方法。

InputStream input =  request.getInputStream();  
                  
ByteArrayOutputStream bytebuffer= new ByteArrayOutputStream();  
byte[] buffer = new byte[1024];  
int len;  
while ((len = input.read(buffer)) > -1 ) {  
    bytebuffer.write(buffer, 0, len);  
}  
bytebuffer.flush();                
  
InputStream stream1 = new ByteArrayInputStream(bytebuffer.toByteArray());  

输出request.getInputStream()内容的方法如下：

StringBuffer buffer = new StringBuffer();
		try (BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream))) {
			String line = "";
			while ((line = reader.readLine()) != null)
				buffer.append(line);
		}

		logger.info("接收xml数据:" + buffer);
