EOFException: No content to map to Object due to end of input

[aj1]

Need to read JSON request payload in my Custom HandlerInterceptorAdapter class to check for a key "token". If all is fine , the dedicated handler should then service the incoming request.

My HandlerInterceptorAdapter is as follows :

public class RequestInterceptor extends HandlerInterceptorAdapter{
	
	public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)throws Exception {
		
		String requestUri = request.getRequestURI();
		
		if(requestUri.endsWith("login") ) {	
 		 			
 			return true;
 			
		} else {
			
			JSONParser jsonParser = new JSONParser();
			
			CustomRequestWrapper customRequestWrapper = new CustomRequestWrapper(request);
			
			JSONObject reqJsonObject = (JSONObject) jsonParser.parse( customRequestWrapper.getBody() );
					
			if ( missing token ) {
				sendErrorResponse(response,"Missing Token");
				
				return false;
			}
			
			else {
		
				// all fine. forward to dedicated handler
				return super.preHandle(customRequestWrapper, response, handler); 
			}
			
		}

	}

My CustomRequestWrapper class is as follow :

public class CustomRequestWrapper  extends HttpServletRequestWrapper {
	
        private final String requestBody;
	
	public CustomRequestWrapper  (HttpServletRequest request) throws IOException {
		
		super(request);
		
		requestBody = IOUtils.toString( request.getInputStream() );
			
	}

	public ServletInputStream getInputStream() throws IOException {
		
		 final ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(requestBody.getBytes());
		 
		 ServletInputStream servletInputStream = new ServletInputStream() {
		     public int read() throws IOException {
		       return byteArrayInputStream.read();
		     }
		   };
  
		 return servletInputStream;
	}
	
	 @Override
	 public BufferedReader getReader() throws IOException {
	   return new BufferedReader(new InputStreamReader(this.getInputStream()));
	 }
	 
	 public String getBody() {	 
	   return this.requestBody;
	 }
}

If the token is not missing the request payload does not get forwarded to dedicated handler .

Stack Trace is as follows:
