跨域cors设置

// 跨域cors设置，允许客户端跨域请求

            response.addHeader("Access-Control-Allow-Origin", "*");

            response.addHeader("Access-Control-Allow-Headers", "Origin, x-requested-with, Content-Type, Accept,X-Cookie");

            response.addHeader("Access-Control-Allow-Credentials", "true");

            response.addHeader("Access-Control-Allow-Methods", "GET,POST,PUT,OPTIONS,DELETE");

 

 

一般将上述代码放在filter中，在filter正常结束之前，例如：

// 测试环境允许跨域
        	if (PropertiesUtil.getBoolean("dev").get()) {
    			response.setHeader("Access-Control-Allow-Origin", "*");
    			response.setHeader("Access-Control-Allow-Methods", "GET,POST");
    		}
        	
        	filterChain.doFilter(request, response);
