Webservices - 为Java中的RESTful Web服务配置JSON

Iam new to webservices and Iam trying to create a restful webservice invoking JSON data. After searching I thought I could use maven to create a webservice and used this link to create a webservice. I installed maven and tried to repeat the same steps given in the link. But when I run the application I get the below error.

我刚接触webservices,Iam试图创建一个调用JSON数据的restful webservice。搜索后,我想我可以使用maven创建一个Web服务,并使用此链接创建一个Web服务。我安装了maven并尝试重复链接中给出的相同步骤。但是当我运行应用程序时,我得到以下错误。

"Failed to execute goal on project printer-status-webapp: Could not resolve dependencies forproject com.example:printer-status-webapp:jar:1.0-SNAPSHOT: Could not find artifact com.sun.jersey:jersey-grizzly:jar:1.0 in glassfish.java.net (http://download.java.net/maven/glassfish) "

“无法在项目printer-status-webapp上执行目标:无法解决项目com.example的依赖关系:printer-status-webapp:jar:1.0-SNAPSHOT:找不到工件com.sun.jersey:jersey-grizzly:jar: 1.0 in glassfish.java.net(http://download.java.net/maven/glassfish)“

I have tomcat running in my machine. I have not installed glassfish. Is it not possible to run the application with tomcat itself.

我有tomcat在我的机器上运行。我没有安装glassfish。是不是可以用tomcat本身运行应用程序。

Anybody pls help me resolve this error.

有人请帮我解决这个错误。

Else any simple example for creating restful webservices with json data will also be helpful

另外,使用json数据创建restful webservices的任何简单示例也会有所帮助

Pls find the pom.xml file

请找到pom.xml文件

The error is basically telling you that maven is looking for the dependency "com.sun.jersey:jersey-grizzly:jar:1.0" in the repository "http://download.java.net/maven/glassfish" that is your pom.xml and it can not find it.

该错误基本上告诉你,maven正在寻找依赖“com.sun.jersey:jersey-grizzly:jar:1.0”的存储库“http://download.java.net/maven/glassfish”这是你的pom .xml,它找不到它。

Do you try it with the Maven Central Repository??

你试试Maven Central Repository吗?

Adding Maven central repository:

添加Maven*存储库:

<repositories>
  <repository>
    <id>central</id>
    <name>Maven Repository Switchboard</name>
    <layout>default</layout>
    <url>http://repo1.maven.org/maven2</url>
    <snapshots>
      <enabled>false</enabled>
    </snapshots>
  </repository>
</repositories>
