用Jena将本体文件存入MySQL数据库的实现方法
以下的文章主要介绍的是使用Jena,将本体文件存入MySQL数据库的实际操作步骤
昨天对其配置了一天,其配置为Jena 2.4.0,MySQL数据库版本为5.1.42-community,JDK版本为1.6.0,MySQLdriver为mysql-connector-java-3.1.14;并按照网络上的资源编写了一个例子,结果出现了一个问题,程序在debug到
使用数据库连接参数创建一个模型制造器
ModelMaker maker = ModelFactory.createModelRDBMaker(conn);
创建一个默认模型,命名为 MyOntology
Model defModel = maker.createModel("MyOntology");
两句的时候,无法从maker.createModel创建模型;
之后写了一些debug调试,一个是使用java的接口来访问mysql,测试成功,说明java与mysql之间的连通无错,那么问题就出现在Jena上;
之后更新Jena到2.6版本,发现问题解决。
心得:
做这方面的研究,发现使用这些开源的软件和api的时候,最容易出现的问题就是版本兼容性的问题,之前就遇到过Protege与graphviz的版本兼容问题,而且一旦是碰到这种问题,经常要花费好长时间,因为最先怀疑的对象往往是知之甚少的自己。
以上的相关内容就是对使用Jena将本体文件存入MySQL数据库的介绍,望你能有所收获。
上述的相关内容就是对使用Jena将本体文件存入MySQL数据库的描述,希望会给你带来一些帮助在此方面。
