1.在访问的Controller中添加HttpServeletResponse参数并设置response的请求头

		public Object Function(String param1,String param2,HttpServletResponse response) {
			//跨域
        	response.setHeader("Access-Control-Allow-Origin", "*");
			//跨域 Header
       	 	response.setHeader("Access-Control-Allow-Methods", "*");
        	response.setHeader("Access-Control-Allow-Headers", "Content-Type,XFILENAME,XFILECATEGORY,XFILESIZE");
        	...
        }

2.直接在请求的Controller上写上@CrossOrigin注解

		@CrossOrigin
		public Object Function(String param1,String param2){
			...
		}
