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;
}

}
