ActiveMQ支持的传输协议

十年热恋 提交于 2020-01-01 13:25:22
Connector:ActiveMQ提供的,用来实现连接通讯的功能。包括:client-tobroker、broker-to-broker。 ActiveMQ允许客户端使用多种协议来连接 配置Transport Connector的文件在activeMQ安装目录的conf/activemq.xml中的<transportConnectors>标签之内。 <transportConnectors> <!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB --> <transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> <transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> <transportConnector name="stomp" uri="stomp://0.0.0.0:61613

ActiveMQ 传输协议

配置 ActiveMQ安装目录的 conf/activemq.xml 中的 <transportConnectors> 标签之内。 配置示例 TCP(默认协议,性能相对可靠) Transmission Control Protocol(TCP) 这是默认的Broker配置,TCP的Client监听端口61616 在网络传输数据前,必须要序列化数据,消息是通过一个叫wire protocol的来序列化成字节流。默认情况下,ActiveMQ把wire protocol叫做OpenWire,它的目的是促使网络上的效率和数据快速交互。 TCP连接的URI形式如: tcp://localhost:port?key=value&key=value (后面的参数是可选) TCP传输的优点: TCP协议传输可靠性高,稳定性强 高效性:字节流方式传递,效率很高 有效性、可用性:应用广泛,支持任何平台 <transportConnectors> <transportConnector name="tcp" uri="tcp://localhost:61616?trace=true"/> </transportConnectors> NIO(基于TCP优化与扩展,扩展性高) New I/O API Protocol(NIO) NIO协议和TCP协议类似,但NIO更侧重于底层的访问操作

RESTful API

前提是你 提交于 2020-01-01 13:08:13
RESTful API 1. 什么是REST REST全称是Representational State Transfer,表述性状态转移。 REST指的是一组架构约束条件和原则。如果一个架构符合REST的约束条件和原则,我们就称它为RESTful架构。 2. 理解RESTful 资源与URI 统一资源接口 资源的表述 资源的链接 状态的转移 2.1 资源与URI 资源的例子: 某用户的手机号码 某用户的个人信息 最多用户订购的GPRS套餐 两个产品之间的依赖关系 某用户可以办理的优惠套餐 某手机号码的潜在价值 要让一个资源可以被识别,需要有个唯一标识,在Web中这个唯一标识就是URI(Uniform Resource Identifier)。 URI既可以看成是资源的地址,也可以看成是资源的名称。如果某些信息没有使用URI来表示,那它就不能算是一个资源, 只能算是资源的一些信息而已。URI的设计应该遵循可寻址性原则,具有自描述性,需要在形式上给人以直觉上的关联。这里以github网站为例,给出一些还算不错的URI: https://github.com/git https://github.com/git/git https://github.com/git/git/blob/master/block-sha1/sha1.h https://github.com/git/git

ContentObserver on content://sms/ in 1.6+?

北城以北 提交于 2020-01-01 10:13:56
问题 I have a content observer that polls content://sms/ in android 1.5 so that I get notified of changes in the sms database and can react to them accordingly. However in 1.6 this doesn't work, has the uri been changed from content://sms/ to something else? I have seen content://mms-sms/ popping up in the logcat on my 1.6 device but I have tried that and it doesn't work. Here is my code String url = "content://sms/"; Uri uri = Uri.parse(url); getContentResolver().registerContentObserver(uri, true

CodeIgniter: URIs and Forms

 ̄綄美尐妖づ 提交于 2020-01-01 07:12:27
问题 I'm implementing a search box using CodeIgniter, but I'm not sure about how I should pass the search parameters through. I have three parameters: the search string; product category; and the sort order. They're all optional. Currently, I'm sending the parameters through $_POST to a temporary method, which forwards the parameters to the regular URI form. This works fine. I'm using a weird URI format though: http://site.com/products/search=computer,sort=price,cat=laptop Does anyone have a

Update on Spotify API not allowing auto play

瘦欲@ 提交于 2020-01-01 07:05:08
问题 I've been developing a website that uses the Spotify API which links to track via the track URI: spotify:track:--TRACKIDHERE-- For instance a band called Circa Waves and their song 'T Shirt Weather': spotify:track:5DrZ0fdWlP0rtwR6VOsrWt However, since the update of the Spotify software recently (where the lyrics button was added and the volume changed to the right hand side) when you click the URI the tracks no longer autoplay when Spotify pops up on your computer. Is there anyway around this

New KitKat URIs dont respond to Intent.ACTION_VIEW

大憨熊 提交于 2020-01-01 04:31:34
问题 Since KitKat has changed the URIs from pickers to likes of content://com.android.providers.media.documents/document/image:3951 then none of my ACTION_VIEW intents work anymore. When for example user picks an image, I use public static void openImage(Fragment f, Uri uri) { Intent intent = new Intent(Intent.ACTION_VIEW); intent.setDataAndType(uri, "image/*"); f.startActivity(intent); } and Android Gallery and Google+ Photos come up, but when selected, the Gallery just shows blank screens,

SimpleCursorAdapter's old constructor deprecated.. really?

柔情痞子 提交于 2019-12-31 22:24:12
问题 Here it says that SimpleCursorAdapter 's API level 1 constructor is deprecated and the use of LoaderManager and CursorLoader is recommended. But delving into the LoaderManager and CursorLoader 's use I found this example where inside an inner class that extends a ListFragment (an extension of Fragment itself I suppose) we create a CursorLoader . Everything seems ok, except for the fact that CursorLoader takes a Uri as an argument. So this implies that I need to create a ContentProvider to get
