在jsp里调用out.flush()和response.flushBuffer()有什么区别

out.flush(); 
out是PrintWriter的实例 
public void flush() 
       Flush the stream. 

response.flushBuffer()； 
response是HttpServletResponse的实例 
public void flushBuffer() 

throws java.io.IOException 
Forces any content in the buffer to be written to the client. A call to this method automatically commits the response, meaning the status code and headers will be written.
