解决跨域的4中实现demo

provider服务提供方，端口8080， springboot
consumer服务消费方，端口8081， ajax

第5中解决方案：
Nginx反向代理解决跨越问题
nginx配置实现：
--------------------------------------------------------
#gzip  on;

upstream claim {
	 server ip:port;
	   }
upstream back {
	 server ip:port;
	   }
server {
	listen       80;
	server_name  ip;#nginx所在服务器ip

	#charset koi8-r;

	#access_log  logs/host.access.log  main;
	
	location / {
		add_header  'Access-Control-Allow-Origin'  '*';
		add_header 	'Access-Control-Allow-Credentials' 'true';
		add_header  'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
		add_header  'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
		proxy_pass   http://claim/;
	}

	location /back {
		add_header  'Access-Control-Allow-Origin'  '*';
		add_header      'Access-Control-Allow-Credentials' 'true';
		add_header  'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
		add_header  'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
		proxy_pass   http://back/;
	}
}

6.18 新增自定义注解、aop切面打印web请求日志
主要是想把controller的每个request请求日志收集起来，调用接口、执行时间、返回值这几个重要的信息存储到数据库里，
然后可以使用火焰图统计接口调用时长，平均响应时长，以便于我们对接口的调用和执行情况及时掌握。
