最新泽西的例子不行 [英] Latest Jersey example does not work

问题描述

我已经收到最新版本的球衣（Bundle-Version：2.13.0）和该版本的示例。然后我尝试（用于测试Restful服务 - \examples\helloworld-pure-jax-rs\src\main\java\org\glassfish\jersey\examples）Eclipse中的Hello World示例。结果是这样：

 Hello WorldJersey示例应用程序
线程mainjava.lang中的异常。 IllegalArgumentException：没有容器提供者支持类型接口com.sun.net.httpserver.HttpHandler 
在org.glassfish.jersey.server.ContainerFactory.createContainer（ContainerFactory.java:87）
在org.glassfish。 jersey.server.internal.RuntimeDelegateImpl.createEndpoint（RuntimeDelegateImpl.java:71）
在org.glassfish.jersey.examples.helloworld.jaxrs.App.startServer（App.java:72）
在org。 glassfish.jersey.examples.helloworld.jaxrs.App.main（App.java:88）
  

我认为该示例应该开箱即用，因为它不使用任何特定的http服务器。只有

  import com.sun.net.httpserver.HttpHandler; 
 import com.sun.net.httpserver.HttpServer; 
  

我的Java版本是：

  java版本1.8.0_25
 Java（TM）SE运行时环境（build 1.8.0_25-b18）
 Java HotSpot（TM）Client VM（build 25.25-b02 ，混合模式，共享）
  

任何想法可能是错或我错过了什么？

解决方案

使用Maven和Eclipse

首先我从命令行尝试使用Maven（你需要安装Maven ）。它的工作正常。

步骤：

1. 已下载泽西2.13示例包从 here


2. 解压到 $ {myJerseyExampleLocation} （无论位置如何）


3. cd $ {myJerseyExampleLocation} / jersey / examples / helloworld-pure-jax- rs


4. mvn package - 下载所有依赖项并运行一个单元测试 HelloWorldTest 成功



5. 要运行主应用程序 mvn exec：java 。这将通过执行程序 - >运行 App maven-plugin 列在pom的< plugins> 部分中。结果：

    应用程序启动。 
   尝试在浏览器中访问http：// localhost：8080 / helloworld。 
   按Enter键停止应用程序... 
     



6. 从浏览器到 HTTP：//本地主机：8080 / HelloWorld的。结果是 Hello World！


7. 返回命令行，然后按Enter键停止服务器






从Eclipse：





我首先删除整个解压缩的示例，因为它已经构建。我想从头开始从Eclipse开始。





步骤：



1. 解压缩


2. 从Eclipse 导入 - > Maven - >现有的Maven项目浏览 helloworld-pure-jax-rs 并选择选择它完成


3. 右键单击项目运行方式 - > Maven Build 。在目标的对话框字段类型包 应用 - >运行。这将抓住所有的依赖关系。您应该获得构建成功以及成功的单元测试。


4. 运行两个选项：
   
   
   
   • 打开应用程序类，右键单击它，运行为 - > Java应用程序。您应该在Eclipse控制台中获得相同的结果，提到Maven步骤5。
   
   
   • 右键单击项目，选择运行为 - > Maven Build （有两个选择您从上一步还没有选择的）。您将再次获得对话框。这允许您配置不同的运行配置。在目标中，键入 exec：java 。然后跑。您应该得到与上述相同的结果。
   
   



在Eclipse环境中，使用1.7进行测试.0_65和1.8.0_20





希望你能让它上班。让我知道你想出了什么。




I have isntalled the latest version of jersey (Bundle-Version: 2.13.0) and the examples for that version. Then I tried (for testing Restful services - \examples\helloworld-pure-jax-rs\src\main\java\org\glassfish\jersey\examples) the Hello World example in Eclipse. The result ist this:

"Hello World" Jersey Example Application
Exception in thread "main" java.lang.IllegalArgumentException: No container provider supports the type interface com.sun.net.httpserver.HttpHandler
at org.glassfish.jersey.server.ContainerFactory.createContainer(ContainerFactory.java:87)
at org.glassfish.jersey.server.internal.RuntimeDelegateImpl.createEndpoint(RuntimeDelegateImpl.java:71)
at org.glassfish.jersey.examples.helloworld.jaxrs.App.startServer(App.java:72)
at org.glassfish.jersey.examples.helloworld.jaxrs.App.main(App.java:88)

I thought the example should work out of the box as it does not use any specific http servers. Only

import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;

My Java version is:

java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) Client VM (build 25.25-b02, mixed mode, sharing)

Any idea what could be wrong or what I missed?

解决方案

With Maven and with Eclipse

First I tried with Maven from command line (you need Maven installed). It worked fine.

Steps:

1. Downloaded Jersey 2.13 Examples bundle from here
2. Unzipped to ${myJerseyExampleLocation} (whatever the location may be)
3. cd ${myJerseyExampleLocation}/jersey/examples/helloworld-pure-jax-rs
4. mvn package - This downloaded all the dependencies and ran one unit test HelloWorldTest successfully

5. To run the main app mvn exec:java. This runs the App class through the exec-maven-plugin listed in the <plugins> section of the pom. Result:

   Application started.
   Try accessing http://localhost:8080/helloworld in the browser.
   Hit enter to stop the application...
   

6. From browser to to http://localhost:8080/helloworld. Result is Hello World!
7. Go back to command line and hit enter to stop server

From Eclipse:

I first delete the entire unzipped example, as it was already built. I wanted to do it from scratch from Eclipse.

Steps:

1. Unzipped
2. From Eclipse Import -> Maven -> Existing Maven Projects Browse for helloworld-pure-jax-rs and select select it Finish
3. Right click on project Run As -> Maven Build. In the dialog in the goals field type package The Apply -> Run. This will grab all the dependencies. You should get a Build Successful along with a successful unit test.
4. Two options to run:
   • Open the App class, right click it and Run as -> Java Application. You should get the same result in the Eclipse console as mention the Maven Step 5.
   • Right click on project, select Run as -> Maven Build (there are two select the one you haven't selected yet from the previous step). You will get the dialog again. This allows you to configure a different run configuration. In the goals type exec:java. Then run. You should get same result as above.

In Eclipse environment, tested with 1.7.0_65 and 1.8.0_20

Hopefully you can get it to work. Let me know what you come up with.
