如何通过使用PostgreSQL的Apache Tomcat Java创建Web服务 [英] How to create webservice in java using apache tomcat using PostgreSQL
问题描述
我想知道如何创建Web服务。我是一个Android开发者。哪种方法适用于Android的Web服务，其实我们正在使用服务器端的Apache Tomcat PostgreSQL中，所以请给我这个问题的任何想法。

推荐答案
presuming由网络服务你的意思是目前最常用的方法之一，REST风格的HTTP + JSON或HTTP + XML，你可能要使用 JAX-RS （的 JSR311 ）。这是的Java EE 的规范，和最容易的方法的一部分要不断前进是只使用 JBoss AS中7 捆绑了它。 JAX-RS的实现也很容易，如果你preFER的Tomcat和Tomcat使用。你想 RestEasy的或的泽西;或者应该罚款。查看的Java EE教程JAX-RS 中的< A HREF =http://jersey.java.net/nonav/documentation/latest/user-guide.html#d4e8相对=nofollow>新泽西入门指南和的 RestEasy的文档。
Presuming that by "web service" you mean one of the most common methods currently used, REST-style HTTP+JSON or HTTP+XML, you probably want to use JAX-RS (JSR311). This is part of the Java EE specification, and the easiest way to get going is to just use JBoss AS 7 which bundles it. JAX-RS implementations are also easy to use with Tomcat if you prefer Tomcat. You want RESTEasy or Jersey; either should be fine. Check out the Java EE tutorial for JAX-RS, the Jersey getting started guide, and the RESTEasy documentation.
如果，事实上，你想一些其他类型的网络服务像 XML-RPC SOAP 或的 CORBA （编辑：为您的文章标签提示），那么（一）重新考虑，他们被所取代的原因和（b）如果必须使用它们，看看实现具体到您必须使用绑定技术。我建议您检查 JAX-WS 以SOAP + WSDL，但我没有使用过它自己，所以我没有什么进一步的提供。我知道 NetBeans IDE中提供一些老派的SOAP / JAX-WS Web服务的支持，但同样没有看着它。
If, in fact, you want some other kind of web service like XML-RPC, SOAP or CORBA (edit: as your post tags suggest), then (a) reconsider, they're being superceded for a reason and (b) if you must use them, look into implementations specific to the binding technology you must use. I'd suggest that you examine JAX-WS for SOAP+WSDL, but I haven't worked with it myself so I have nothing further to offer. I know the NetBeans IDE offers some kind of old-school SOAP/JAX-WS web services support, but again haven't looked into it.
我希望这将是比较容易的方式与Android中JAX-RS的工作比将与SOAP工作。 JAX-RS客户端不需要任何东西比HTTP客户端库和XML或JSON解析器/作家更多 - 尽管存在针对REST风格的API客户端库和使他们更容易的工作。
I expect it'll be way easier to work with JAX-RS in Android than it will be to work with SOAP. A JAX-RS client doesn't need to be anything more than a HTTP client library and an XML or JSON parser/writer - though client libraries that target REST-style APIs exist and make them even easier to work with.
你真的需要SOAP？或者你只是需要任何一种基于Web的客户端/服务器通信的？究竟什么是你想实现这个？哪里PostgreSQL的进入呢？
Do you really need SOAP? Or do you just need any kind of web based client/server communication? What exactly are you trying to achieve with this? Where does PostgreSQL come into it?
