定时任务使用fegin接口调用其他服务-获取不到token

一、 添加工具类

@Configuration
public class FeignConfiguration implements RequestInterceptor {
    @Override
    public void apply(RequestTemplate template) {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder
                .getRequestAttributes();
        if (attributes == null) {
            RequestContextHolder.setRequestAttributes(new ServletRequestAttributes(new MockHttpServletRequest()));//为空进行新建
            attributes = (ServletRequestAttributes) RequestContextHolder
                .getRequestAttributes();//重新赋值
        }
        HttpServletRequest request = attributes.getRequest();
        // 对消息头进行配置
        Enumeration<String> headerNames = request.getHeaderNames();
        if (headerNames != null) {
            /**
             * 判断有没有token，如果是定时任务进来，是没有token的，此时用默认token以调用到对应的Feign服务
             */
            boolean flag = true;
            while (headerNames.hasMoreElements()) {
                String name = headerNames.nextElement();
                String values = request.getHeader(name);
                if(name.equals("token")){
                    flag = false;
                }
                template.header(name, values);
            }
            if(flag){
                template.header("token","!@#$%^&*()Cid6032001_Feign");
            }
        }
        // 对请求体进行配置
        Enumeration<String> bodyNames = request.getParameterNames();
        StringBuffer body =new StringBuffer();
        if (bodyNames != null) {
            while (bodyNames.hasMoreElements()) {
                String name = bodyNames.nextElement();
                String values = request.getParameter(name);
                body.append(name).append("=").append(values).append("&");
            }
        }
        if(body.length()!=0) {
            body.deleteCharAt(body.length()-1);
            template.body(body.toString());
        }
    }

}
