Question

我是webservices的新手，我试图创建一个调用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link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。

“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）“

我在我的机器上运行了tomcat。我没有安装glassfish。是否无法使用tomcat本身运行应用程序。

任何人都帮我解决这个错误。

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

请找到pom.xml文件

Answer 1

错误基本上告诉你maven正在寻找依赖＆＃34; com.sun.jersey：jersey-grizzly：jar：1.0＆＃34;在存储库＆＃34; http://download.java.net/maven/glassfish＆＃34;那是你的pom.xml，它无法找到它。

您是否尝试使用Maven Central Repository？

Answer 2

添加Maven中央存储库：

<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>
