常量类中定义一个集合，代码中判断是否有包含的

//常量类
public class Constant {
	
    public static final  List sysNamespace = Arrays.asList("default", "devops", "ingress-nginx","kube-node-lease","kube-public","kube-system","monitoring");
}

//代码中判断
Iterator iterator = pods.iterator();
while(iterator.hasNext()){
	BizPod pod = iterator.next();
	if(Constant.sysNamespace.contains(pod.getNamespace())){
		iterator.remove();
	}
}
