java - 如何将 51Degrees.Mobi 与 Maven 一起使用

Question

我正在尝试让 51Degrees.mobi 与我的 Maven、JSF 和 Java 项目一起使用，但到目前为止我还没有运气。我已经从http://51degrees.mobi/Support/Documentation/Java.aspx下载了2个jar包并按照说明进行操作。我现在有一个看起来像这样的过滤器

    import fiftyone.mobile.detection.BaseDeviceInfo;
    import fiftyone.mobile.detection.Provider;
    import fiftyone.mobile.detection.binary.BinaryException;
    import fiftyone.mobile.detection.binary.Reader; 

     public void doFilter(ServletRequest request, ServletResponse response,FilterChain chain) throws IOException, ServletException {

    HttpServletRequest httpRequest = (HttpServletRequest) request;
    String s = httpRequest.getHeader("user-agent");

    //Create a Provider object
      Provider p;
    try {
        p = Reader.create();


    } catch (BinaryException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


    //Provider p = Reader.create(PATH_TO_PREMIUM_DATA);


      //Read in a HttpServletRequest or User Agent String
      BaseDeviceInfo b = p.getDeviceInfo(s);

      //Get the value of a property
      String result = b.getFirstPropertyValue("IsMobile");

      //Check the property value
      if(result.equals("True")){
        System.out.println("This is mobile");
      }

      if(result.equals("False")){
        System.out.println("This is not mobile");
      }

      //Before exiting your application, ensure you dispose of the Provide to
      //release it's resources such as it's thread pool
       p.destroy();
   }   

这不会引发任何错误。通过在线查看，我发现我必须添加到 pom 文件中的依赖项，并且我已经拥有它了

     <dependency><!-- Start 51Degrees.mobi dependencies -->
        <groupId>mobi.51degrees</groupId>
        <artifactId>detection</artifactId>
        <version>2.1.15.1</version>
    </dependency><!-- End 51Degrees.mobi dependencies -->

文件本身也没有抛出任何错误，但是当我在目录中使用 mvn clean install 时，出现以下错误

大家有什么想法吗？

Answer 1

根据 rules ，我声明我是 51Degrees.mobi 的一名 Java 开发人员。不知道此时查看页面是否解决了您的问题？所以我想我应该添加更多信息。

首先，如果您有两个 Jar 文件，那么您使用的是 2.1.16.1 而不是 2.1.15.1，尽管这不会直接影响您的问题，但为了清楚起见，我想我会这么说:)。

此外，在发布当前答案后，最近通过 Maven 中央存储库提供了 51Degrees.mobi 的 2.1.16.1 版本解决方案。所以现在你需要做的就是将此依赖项添加到你的 pom 中:

 <dependency><!-- Start 51Degrees.mobi dependencies -->
    <groupId>net.sourceforge.fiftyone-java</groupId>
    <artifactId>51Degrees.mobi.detection.core</artifactId>
    <version>2.1.16.1</version>
</dependency><!-- End 51Degrees.mobi dependencies -->

如果您想使用我们的第二个 jar，只需将“core”替换为“webapp”即可。
