FUSEKI的MySQL配置
我需要测试一个特定的数据库解决方案，与使用fuseki+mysql作为三重存储的旧数据库解决方案进行对比。基本上，我所需要做的就是对我以前用SPARQL创建的数据库进行查询。问题是，我似乎无法配置fuseki来为我提供该数据库的端点。我使用普通的标准java编码（JDBC而不使用Jena SDB组件）创建了数据库。我使用的mysql版本是：FUSEKI的MySQL配置,mysql,jdbc,jena,fuseki,Mysql,Jdbc,Jena,Fuseki,我需要测试一个特定的数据库解决方案，与使用fuseki+mysql作为三重存储的旧数据库解决方案进行对比。基本上，我所需要做的就是对我以前用SPARQL创建的数据库进行查询。问题是，我似乎无法配置fuseki来为我提供该数据库的端点。我使用普通的标准java编码（JDBC而不使用Jena SDB组件）创建了数据库。我使用的mysql版本是： mysql Ver 14.14 Distrib 5.5.37, for debian-linux-gnu (x86_64) using readline

Thx的帮助看起来像是纯粹的类路径问题，与您拥有的任何其他东西无关。我找到了。这里的要点是： 同样值得注意的是，当您使用java-jar命令行时 选项将Java程序作为可执行JAR运行，然后 CLASSPATH环境变量以及-cp和 -类路径开关将被忽略。在本例中，您可以使用 类路径属性。在清单文件中的短类路径属性中 重写由-cp、-classpath或classpath指定的类路径 环境变量 希望这有帮助
