我已经设计了一个块来在我的Java类中对Jena SDB进行查询,但我不知道如何添加我的规则,它位于My类的文件中。我添加了代码。
String jdbcURL = "jdbc:mysql://localhost:3306/ontology";
System.out.println("##### GETUSERSTYPE #####");
JDBC.loadDriverMySQL();
// Setup - make the JDBC connection and read the store description once.
Connection jdbc = makeConnection(jdbcURL) ;
// Make a store description without any connection information.
StoreDesc storeDesc = new StoreDesc(LayoutType.LayoutTripleNodesHash,DatabaseType.MySQL) ;
SDBConnection conn = new SDBConnection(jdbc) ;
Store store = StoreFactory.create(storeDesc, conn) ;
Dataset ds = DatasetStore.create(store) ;
QueryExecution qe = QueryExecutionFactory.create(query, ds) ;
