在jsp或者在servlet中有时要用到response.getOutputStream()，但是此时会在后台报这个错误java.lang.IllegalStateException: getOutputStream() has already been called for this respons，这个异常时因为response.getOutputStream()跟response.getWriter()相冲突造成的，解决方法如下：
out.clearBuffer();
out = pageContext.pushBody();
在调用response.getOutputStream()之前加上上面两代码就能完美解决了！！
out.clearBuffer();
out = pageContext.pushBody();
在调用response.getOutputStream()之前加上上面两代码就能完美解决了！！
