配置文件--spring cloud Config

配置中心--Spring cloud Config

通过本次学习，我们应该掌握：

• Config Server 读取配置文
• Config Server 从远程 Git 仓库读取配置文
• 搭建芮可用 Config Server 集群。
• 使用 Spri ng Cloud Bus 刷新配置。

构建Config Server

构建工程，在这里我们不在赘述，相信大家也会,在这里我们主要说一下,配置与其主要实现方式.

@Component

public class MyFilter extends ZuulFilter

{

private static Logger log=LoggerFactory.getLogger(MyFilter.class);

@Override
	public String filterType(){
	  return Pre_TYPE;
}

@Override
	public int filterOrder(){
	   return 0;
}

@Override
	public boolean shouldFilter(){
	    return true;
}

public Object run(){
	RequestContext ctx=RequestContext.getCurrentContext();
	HttpServletRequest request=ctx.getRequest("");
	Object accessToken=request.getParameter("token");
	if(accessToken==null){
		log.warn("token is empty");
		ctx.setSendZuulResponse(false);
		ctx.setResponseStatusCode(401);
		try{
			ctx.getResponse().write("token is empty");
		}catch(Exception e){
			return null;
		}
	}
	log.info("ok");
	return null;
}

}
