问题 I have to set some http header fields in a Apache CXF client: I tried it via Interceptor: public class HttpHeaderInterceptor extends AbstractPhaseInterceptor<Message> { private String userId; private String xAuthorizeRoles; private String host; public HttpHeaderInterceptor() { super(Phase.POST_PROTOCOL); } @Override public void handleMessage(Message message) throws Fault { Map<String, List> headers = (Map<String, List>) message.get(Message.PROTOCOL_HEADERS); try { System.out.println(

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 基础 JVM内存模型(堆、方法区、本地方法栈、JVM栈、程序计数器) GC回收方式(计数器、可达性分析等) 类加载器(AppClassLoader、ExtClassLoader、BootstrapClassLoader) OSI七层模型(物理层->数据链路层->网络层->传输层->会话层->表现层->应用层) 设计模式(单例模式、观察者模式、装饰者模式、工厂模式、代理模式) HashMap实现原理(JDK1.8) 分布式调度任务流程(XX-JOB):任务注册->任务下发->监控->日志信息收集 算法题(斐波那契数列、杨辉三角形、字符串123变为数字123) 多线程 1.validate 实现原理:将缓存的最新值更新到内存中,同时通知其他处理器,从内存中重新取值,此时其他处理器的缓存值失效 应用场景:插入内存屏障,防止指令重排序 目的:实现共享变量的可见性 2.transient 目的:防止不必要的变量序列化 3.syncronized 实现原理:反编译源码中存在监控计数器,线程获取锁时->计数器+1,锁释放时->计数器-1.当其他线程得知计数器为0时,线程可以进入,否则,线程需要等待. 应用场景:锁(可重入) 备注:reetrantLock是jdk5引入的并发包,作用类似于syncronized

How to use angular2 http API for tracking upload/download progress

由 独自空忆成欢 提交于 2020-01-09 09:01:27
问题 Tho there are many adhoc libraries supporting upload/download progress in angular2, I do not know how to do use native angular2 http api to show progress while doing upload/download. The reason why I want to use native http api is because I want to utilise http interceptors(http API wrappers) around native http api that validate, cache & enrich the actual http request being sent such as this & this Besides angular's http api is much more robust than any adhoc APIs There is this nice article
