Ajax 跨域问题（bootstrap-table应用）

因为开启了两个Tomcat 启用服务端和客户端，端口不一样，产生了跨域的问题

报错： CORS 头缺少 'Access-Control-Allow-Origin'

解决方法：

在controller中添加：

	        response.setHeader("Access-Control-Allow-Origin", "*");
		response.setHeader("Access-Control-Allow-Headers", "Authentication");
		response.addHeader("Access-Control-Allow-Headers", "Origin, No-Cache, X-Requested-With, If-Modified-Since, Pragma, Last-Modified, Cache-Control, Expires, Content-Type, X-E4M-With");
		response.addHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS");

即可解决跨域问题
