我正在尝试让51Degrees.mobi与我的Maven，JSF和Java项目一起工作，但是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，并按照说明进行了操作。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();
}
多数民众赞成在没有任何错误。通过在线查找，我发现必须添加到pom文件中的依存关系就这样了
<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，文件本身没有引发任何错误，但是当我在目录中使用mvn clean install时，出现以下错误

谁有想法？
最佳答案
按照rules，我声明我以Java开发人员的身份为51Degrees.mobi工作。我目前无法通过查看页面来解决问题吗？所以我想我会补充一些信息。
首先，如果您有两个Jar文件，则您使用的是2.1.16.1而不是2.1.15.1，尽管这不会直接影响您的问题，我想我想说的很清楚：）。
同样，在发布了当前答案之后，最近通过Maven中央存储库提供了51Degrees.mobi的2.1.16.1版解决方案。因此，现在您要做的就是将此依赖项添加到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”。
