html使用，就像使用一个第三方网络上的js文件：<script language='javascript' src='http://www.yousite.com/rootpath/printWriterHtmlJavascript/PrintWriter'></script>

	 @RequestMapping(value="/PrintWriter", method={RequestMethod.GET,RequestMethod.POST},produces="text/html;charset=UTF-8")
	 @ResponseBody
	 public void PrintWriter(HttpServletRequest request,HttpServletResponse response){
	 	
	 	 //设置跨域访问
	 	 response.setHeader("Access-Control-Allow-Origin","*");
	 response.setHeader("Access-Control-Allow-Methods","POST, GET, OPTIONS, DELETE");
	 response.setHeader("Access-Control-Max-Age","3600");
	 response.setHeader("Access-Control-Allow-Headers","x-requested-with,Authorization");
	 response.setHeader("Access-Control-Allow-Credentials","true");
	 
	 //设置JavaScript方式输出
	 	response.setContentType("text/javascript;charset=utf-8");
	 	PrintWriter out = = response.getWriter();
	 	StringBuilder sb = new StringBuilder();
	
		 //"<script type='text/javascript'>"	
			sb.append("window.onload = function(){");	 		
			sb.append("console.log('javaweb输出JavaScript代码（相当于别人引用了一个.js的文件)');");	 					
			sb.append("};");			 			 			 
		 //"</script>"
			 out.write(sb.toString());//或者out .println(mm);
			 out.flush();
 out.close();
 //自己处理异常try/catch,这里不做列举
	 	
	 }
