如何使用51Degrees.Mobi与Maven

标签: java maven-2 servlet-filters 51degrees

我正在努力让51Degrees.mobi与我的Maven,JSF和Java项目合作,但到目前为止我没有运气。我已从http://51degrees.mobi/Support/Documentation/Java.aspx下载了2个罐子并按照说明操作。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();
   }   

多数民众赞成没有错误。从在线查看我发现我必须添加到pom文件的依赖性,我就这样了

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

同样,文件本身不会抛出任何错误,但是当我在目录中使用mvn clean install时出现以下错误

有人有什么想法吗?

3 个答案:

答案 0 :(得分:2)

根据rules,我声明我作为Java开发人员为51Degrees.mobi工作。如果您解决了问题,我不确定此时此页面是否正常?所以我想我会添加更多信息。

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,虽然这不应该直接影响您的问题,我想我会说清楚:)。

此外,51Degrees.mobi的2.1.16.1版解决方案最近在发布当前答案后通过maven中央存储库提供。所以现在你应该做的就是将这个依赖项添加到你的pom:

 <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 -->

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

答案 1 :(得分:1)

确保您的存储库(本地或远程)中有51Degrees.mobi。我在maven公共存储库中进行了快速搜索,但我找不到它。

如果jar在你的本地文件夹中某处。你可以使用

mvn install:install-file -Dfile=your-artifact-1.0.jar \
                         [-DpomFile=your-pom.xml] \
                         [-Dsources=src.jar] \
                         [-Djavadoc=apidocs.jar] \
                         [-DgroupId=org.some.group] \
                         [-DartifactId=your-artifact] \
                         [-Dversion=1.0] \
                         [-Dpackaging=jar] \
                         [-Dclassifier=sources] \
                         [-DgeneratePom=true] \
                         [-DcreateChecksum=true]

检查链接maven install plugin

答案 2 :(得分:1)

尝试在存储库中找到jar: jar应该驻留在这里:

~/.m2/repository/mobi/51degrees/detection/2.1.15.1/

如果你在那里找到它,检查它是否包含包

下的类

fiftyone.mobile.detection

- 更新 -

如果您没有找到此jar,可以使用以下选项之一:

  1. 使用''系统''范围依赖 - 它使您的构建平台/环境依赖,所以我不推荐它,尽管它是最简单的方法。

  2. 使用mvn install:install-file以便将jar放入本地maven存储库。它比第一种方法好得多,但是在每个本地环境中运行maven之前你仍然需要使用这个命令/你的本地存储库被清除......

  3. 在服务器上的某处维护您自己的maven存储库,映射maven以使用此存储库。这是迄今为止我所知道的最佳方法。最好的方法是使用“Nexus”或“Artifactory”等存储库代理。在最坏的情况下,您可以将存储库创建为纯文件系统,并通过Web服务器(如apache)访问它。 在此存储库中,您将能够存储公共maven存储库中不存在的第三方jar,您自己的工件,或者可能不是免费/开源的工件,因此无法在公共maven存储库中维护(如此您可以使用的商业软件。

  4. 希望这有帮助
