virtuoso.jena.driver是否有可用的依赖项? [英] Is there any usable dependency for virtuoso.jena.driver?

问题描述

我要做的是将数据从芝麻传递到专家.

What I want to do is passing data from sesame to virtuoso.

这是我的代码:

public static void sesame2virtuoso(String server, String repo, String graphName) throws IOException, RepositoryException {

    //connect sesame
    HTTPRepository repository = new HTTPRepository(server, repo);
    repository.setUsernameAndPassword(PropertiesUtil.PropValues("user"), PropertiesUtil.PropValues("password"));
    repository.initialize();
    RepositoryConnection connection = repository.getConnection();
    ValueFactory factory = connection.getValueFactory();

    try {
        RepositoryResult<Statement> statements = connection.getStatements(null, null, null, false);
        Statement statement;
        String sub, pre, obj;
        VirtGraph graph = new VirtGraph(graphName, URL, "dba", "dba");
        int count = 0;
        while (statements.hasNext()) {
            statement = statements.next();
            sub = statement.getSubject().stringValue();
            pre = statement.getPredicate().stringValue();
            obj = statement.getObject().stringValue();

            Node sub1 = Node.createURI(sub);
            Node pre1 = Node.createURI(pre);
            Node obj1 = Node.createURI(obj);
            try {
                graph.add(new Triple(sub1, pre1, obj1));                } catch (Exception e) {
                continue;
            }

        }

    } catch (Exception e) {
        e.printStackTrace();
    }
}

我在maven项目中使用了它.因此，我为此搜索了一些pom，但它们都无法正常工作.

I used it in a maven project. So I searched some poms for that, but all of them can't work.

我认为原因是依赖版本错误或我的IDE发生了问题.我该怎么办?

I think the reason is the dependencies versions are wrong or something wrong happened with my idea IDE. What should I do?

谢谢您的帮助.

推荐答案

这些库(virt_jena3.jar和virtjdbc4.jar)在任何公共Maven存储库中都不存在.

These libraries ( virt_jena3.jar and virtjdbc4.jar) do not exist in any public maven repository.

这不是您的错，是Openlink员工的错.

It's not your fault, is the Openlink people's fault.

如果需要它们，请按以下步骤操作.

If you want them, here are the steps.

wget http://download3.openlinksw.com/uda/virtuoso/rdfproviders/jena/30/virt_jena3.jar -P /tmp/
wget http://download3.openlinksw.com/uda/virtuoso/jdbc/virtjdbc4.jar -P /tmp/

2.将它们安装在本地Maven存储库中

mvn install:install-file -q \
 -Dfile=/tmp/virt_jena3.jar \
 -DgroupId=com.openlink.virtuoso \
 -DartifactId=virt_jena3 \
 -Dversion=3.0 \
 -Dpackaging=jar \
 -DgeneratePom=true

mvn install:install-file -q \
 -Dfile=/tmp/virtjdbc4.jar \
 -DgroupId=com.openlink.virtuoso \
 -DartifactId=virtjdbc4 \
 -Dversion=4.0 \
 -Dpackaging=jar \
 -DgeneratePom=true

3.将依赖项添加到您的pom

<!-- These do not have a Maven repository -->
<dependency>
  <groupId>com.openlink.virtuoso</groupId>
   <artifactId>virtjdbc4</artifactId>
   <version>4.0</version>
</dependency>

<dependency>
  <groupId>com.openlink.virtuoso</groupId>
   <artifactId>virt_jena3</artifactId>
   <version>3.0</version>
</dependency>

4.将有关步骤的信息添加到您的文档中

或者，您可以使用<system>范围指向jar，但是如果要创建uber-jar，这会产生问题.如果您仍然想尝试，请在以下片段中添加<dependency>标记

Alternatively you could use the <system> scope to point to the jars, but this will generate problems if you want to create an uber-jar. If you still want to try, here is the fragment to add in the <dependency> tag

  <scope>system</scope>
  <systemPath>/path/to/jar/virtjdbc4.jar</systemPath>
