小编use*_*976的帖子

在链接的当前文档示例中:https: //github.com/owlcs/owlapi/blob/version5/contract/src/test/java/org/semanticweb/owlapi/examples/Examples.java 没有示例如何从本地文件加载本体.只有一种方法可以从字符串加载它.

在过去,当我使用owl-api版本3时,以下代码完美地运行:

    OWLOntologyManager manager =OWLManager.createOWLOntologyManager();
    File file = new File (path);
    OWLOntology ont = manager.loadOntologyFromOntologyDocument(IRI.create(file));

但是,在此版本中,前一代码的最后一行:

manager.loadOntologyFromOntologyDocument(IRI.create(file));

返回此错误:

    Exception in thread "main" java.lang.NoSuchMethodError:

请注意附件,一个小测试java项目,链接:

请问我做错了什么,我确定这个代码

请您提供正确的方法,并将其添加到链接https://github.com/owlcs/owlapi/blob/version5/contract/src/test/java/org/semanticweb/中的教程示例中owlapi /示例/ Examples.java

非常感谢你花时间陪伴.真诚的问候
