如何将jad插件导入eclipse

包下载完后。将其中的jad.exe直接拖到你的jdk目录/bin/下面。而且必须保证你的jdk环境配置好了。ctrl+r。输入cmd->jad。如果出现这玩意说明配置是成功的。然后将下载的zip包中的jar插件放在你的eclipse的plugin目录中。重启你的eclipse。打eclipse菜单window->prefrencres-》输入jad其中path to decompiler就是你的jad路径了。下面那个不用管。如果输入jad没有出现这玩意那应该是你的插件没有放对位置或者版本已经不支持了。截止到目前的myeclipse或者eclipse或springtoolsuit都是可以的。找到你要反编绎的类。最好不要是jdk自带的类,可以找apache这些其它的类测试一下看是否可以反编绎。按住ctrl按不松-》鼠标移到你要反编绎的类上-》左键点击进入。如果可以反编绎应该出现下面的:说明反编绎成功。如果不能反编绎,请设置一下文件类型的打开方式,也就是.class文件用jad.exe打开。windows->prefrences->输入:file ass

myeclipse9.0 jad3怎么配置

1: Jadclipse插件的安装方法:直接将jadclipse_3.1.3.jar(网上免费下载)复制到%ECLIPSE_HOME%plugins目录下。2: 下载并复制jad.exe至你的%JAVA_HOME%in目录下,这样做的好处是使用方便。然后在Eclipse中设置一下, 选择”窗口”-->“首选项”-->“Java”--> “JadClipse”,在path to decompiler中输入jad.exe的绝对路径(eg: E:TDjdk1.6.0_21injad.exe)。这样做是为了保证反编译的效果。在Directory for temporary files中指定临时文件的路径(eg: E:TDjdk1.6.0_21 emp)完成配置,重启eclipse后,在你图片的目录下会出现 jadClipse,此时你的eclipse 应该已经可以查看 .class文件了.

如何ServiceStack PooledRedisClientManager故障转移的工作

我一直认为readWriteHosts数组中只能输入ip:port来代表一个redis 实例的连接,但是如何把密码加在里面呢?想不到如何实现,只能下载了源代码查看,原来这个实现是通过分隔字符串来实现, 1 /// <summary> 2 /// IP地址中可以加入auth验证 password@ip:port 3 /// </summary> 4 /// <param name="hosts"></param> 5 /// <returns></returns> 6 public static List<RedisEndpoint> ToRedisEndPoints(this IEnumerable<string> hosts) 7 { 8 if (hosts == null) return new List<RedisEndpoint>(); 9 //redis终结点的列表 10 var redisEndpoints = new List<RedisEndpoint>(); 11 foreach (var host in hosts) 12 { 13 RedisEndpoint endpoint; 14 string[] hostParts; 15 if (host.Contains("@")) 16 { 17 hostParts = host.SplitOnLast("@"); 18 var password = hostParts[0]; 19 hostParts = hostParts[1].Split(":"); 20 endpoint = GetRedisEndPoint(hostParts); 21 endpoint.Password = password; 22 } 23 else 24 { 25 hostParts = host.Split(":"); 26 endpoint = GetRedisEndPoint(hostParts); 27 } 28 redisEndpoints.Add(endpoint); 29 } 30 return redisEndpoints; 31 }在ip:port前面加上@用来表示密码,比如password@ip:port ,现在才知道能看到源码的程序是多么的幸福的一件事。开源伟大。master:设置密码:config set requirepass passwordslave 指定master密码:config set masterauth password 就可以实现在master设置密码,并且不需要重启redis实例 非常方便,但是这种方式重启后失效。

He lost his arm but is still climbing Aron Ralston is an American man who is interested in mountain climbing. As a mountain climber, Aron is used to taking risks. This is one of the exciting things about doing dangerous sports. There were many times when Aron almost lost his life because of accidents. On April 26,2003, he found himself in a very dangerous situation when climbing in Utah. On that day, Aron"s arm was caught under a 2,000-kilo rock that fell on him when he was climbing by himself in the mountains. Because he could not free his arm, he stayed there for five days and hoped that someone would find him. But when his water ran out, he knew that he would have to do something to save his own life He was not ready to die that day. So he used his knife to cut off half his right arm. Then, with his left arm, he bandaged himself so that he would not lose too much blood. After that, he climbed down the mountain to find help. After losing his arm, he wrote a book called Between a Rock and a Hard Place. This means being in a difficult situation that you cannot seem to get out of.

阿伦·罗尔斯顿是一个对登山感兴趣的美国人。作为一名登山者,阿伦习惯了冒险。这就是做危险性运动时令人兴奋的事情之一。有好多次,阿伦差点因为意外丢掉性命。2003年4月26日,当他在犹他州登山的时候,他发现自己身处一个非常危险的境地。那天,阿伦独自一人在山里登山,一块360公斤重的石头落在他身上,他的手臂被砸中了。由于他无法抽出他的手臂,他就在那待了五天,期盼着有人会发现他。但当他的水喝完的时候,他知道他得做些什么来拯救自己的生命。他不准备那天就死去。所以,他用他的刀砍掉了他的半截右臂。接着,他用左臂为自己缠上绷带,这样他就不会失血过多。之后,他爬下山去寻求帮助。失去手臂后,他写了一本名为《生死两难》的书。它的意思是“处于一个你似乎无法摆脱的困境之中”。在这本书里,阿伦讲述了做出好决定和掌控自己人生的重要性。他是如此热爱登山,以至于有了这次经历之后他还在继续登山。我们有阿伦一样的精神吗?在我们发现自己处于“生死两难”之前,在我们不得不做一个可能意味着生死的决定之前,咱们好好想想吧

closeablehttpclient httpclient 线程安全吗

安全的1、httpclient总结:一、基本知识准备(1)构建URI工具类,URIBuilder(2)HttpResponse类,可以添加Header信息获取所有Header信息的方法,调用HeaderIterator接口HeaderIterator it = response.headerIterator("Set-Cookie");while (it.hasNext()) {System.out.println(it.next());}(3)HttpEntity内容实体 可以被装入Request和Response中..只有独立的entity才可以被重复调用.当请求需要entity HttpEntity.writeTo(OutputStream)从响应中解析entity HttpEntity.getContent()HttpEntity.getContentType()HttpEntity.getContentLength()HttpEntity.getContentEncoding()对entity进行解析可采用流的方式或者调用EntityUtils,但后者有长度的限制2048利用 BufferedEntity可以将entity缓存到本地磁盘,用来进行多次读取.创建entity信息时需要指定meta信息,包括contentType(4)可以调用ResponseHandler写入响应统一处理二、常用策略keep-Alieve策略:自定义ConnectionKeepAliveStrategy重定向策略:LaxRedirectStrategy三、资源分配当CloseableHttpClient不再需要,并且不再连接管理的范围,需要调用CloseableHttpClient.close()方法将其关闭..四、HttpClient状态管理1、在HTTP上下文中,很多有逻辑关系的请求都可以放入到同一个session中..HttpClient本身线程HttpContext 包含任意的键值对,因此线程不安全..通常建议每个线程拥有自己的上下文 2、自动恢复机制---->HttpRequestRetryHandlerHttpRequestRetryHandler myRetryHandler = new HttpRequestRetryHandler() {public boolean retryRequest(IOException exception,int executionCount,HttpContext context) {if (executionCount >= 5) {// Do not retry if over max retry countreturn false;}if (exception instanceof InterruptedIOException) {// Timeoutreturn false;}if (exception instanceof UnknownHostException) {// Unknown hostreturn false;}if (exception instanceof ConnectTimeoutException) {// Connection refusedreturn false;}if (exception instanceof SSLException) {// SSL handshake exceptionreturn false;}HttpClientContext clientContext = HttpClientContext.adapt(context);HttpRequest request = clientContext.getRequest();boolean idempotent = !(request instanceof HttpEntityEnclosingRequest);if (idempotent) {// Retry if the request is considered idempotentreturn true;}return false;}};CloseableHttpClient httpclient = HttpClients.custom().setRetryHandler(myRetryHandler).build();4、多线程中的应用AtomicInteger,,,,待研究...从连接管理器中获取连接(1)通过HttpClientConnectionManager来管理一个连接HttpClientContext context = HttpClientContext.create();HttpClientConnectionManager connMrg = new BasicHttpClientConnectionManager();HttpRoute route = new HttpRoute(new HttpHost("www.yeetrack.com", 80));// 获取新的连接. 这里可能耗费很多时间ConnectionRequest connRequest = connMrg.requestConnection(route, null);// 10秒超时HttpClientConnection conn = connRequest.get(10, TimeUnit.SECONDS);try {// 如果创建连接失败if (!conn.isOpen()) {// establish connection based on its route infoconnMrg.connect(conn, route, 1000, context);// and mark it as route completeconnMrg.routeComplete(conn, route, context);}// 进行自己的操作.} finally {connMrg.releaseConnection(conn, null, 1, TimeUnit.MINUTES);}通过更复杂的PoolingHttpClientConnectionManager来管理多个连接,适合多线程中的请求PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();// 将最大连接数增加到200cm.setMaxTotal(200);// 将每个路由基础的连接增加到20cm.setDefaultMaxPerRoute(20);//将目标主机的最大连接数增加到50HttpHost localhost = new HttpHost("www.yeetrack.com", 80);cm.setMaxPerRoute(new HttpRoute(localhost), 50);CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(cm).build();示例1---------------------------------PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(cm).build();// URL列表数组String[] urisToGet = {"http://www.domain1.com/","http://www.domain2.com/","http://www.domain3.com/","http://www.domain4.com/"};// 为每个url创建一个线程,GetThread是自定义的类GetThread[] threads = new GetThread[urisToGet.length];for (int i = 0; i < threads.length; i++) {HttpGet httpget = new HttpGet(urisToGet[i]);threads[i] = new GetThread(httpClient, httpget);}// 启动线程for (int j = 0; j < threads.length; j++) {threads[j].start();}// join the threadsfor (int j = 0; j < threads.length; j++) {threads[j].join();}自定义类GetThreadstatic class GetThread extends Thread {private final CloseableHttpClient httpClient;private final HttpContext context;private final HttpGet httpget;public GetThread(CloseableHttpClient httpClient, HttpGet httpget) {this.httpClient = httpClient;this.context = HttpClientContext.create();this.httpget = httpget;}@Overridepublic void run() {try {CloseableHttpResponse response = httpClient.execute(httpget, context);try {HttpEntity entity = response.getEntity();} finally {response.close();}} catch (ClientProtocolException ex) {// Handle protocol errors} catch (IOException ex) {// Handle I/O errors}}}注意:即使httpclient可以被多线程访问,仍建议每个httpclient采用自己的context5、 public static class IdleConnectionMonitorThread extends Thread {private final HttpClientConnectionManager connMgr;private volatile boolean shutdown;public IdleConnectionMonitorThread(HttpClientConnectionManager connMgr) {super();this.connMgr = connMgr;}@Overridepublic void run() {try {while (!shutdown) {synchronized (this) {wait(5000);// 关闭失效的连接connMgr.closeExpiredConnections();// 可选的, 关闭30秒内不活动的连接connMgr.closeIdleConnections(30, TimeUnit.SECONDS);}}} catch (InterruptedException ex) {// terminate}}public void shutdown() {shutdown = true;synchronized (this) {notifyAll();}}}
