如何使用java連接orientdb數據庫？

Question

我試圖用java與orientdb數據庫連接。這樣 OrientGraph odb = new OrientGraph("plocal:C:/Users/USER/Desktop/orientdb/databases/testJ", "admin", "admin");

它顯示錯誤

HTTP Status 500 - Handler processing failed; nested exception is java.lang.NoClassDefFoundError: com/orientechnologies/orient/core/db/record/ODatabaseRecord

我的依賴..

的ODatabaseRecord似乎從新版本被棄用。我對你的代碼進行了下列修改，並且它工作了（刪除了所有其他依賴項）。

POM

<dependency> 
    <groupId>com.orientechnologies</groupId> 
    <artifactId>orientdb-core</artifactId> 
    <version>2.0.8</version> 
</dependency> 
<dependency> 
    <groupId>com.orientechnologies</groupId> 
    <artifactId>orientdb-jdbc</artifactId> 
    <version>2.0.8</version> 
</dependency> 

Java代碼的

OrientGraphFactory ogf = new OrientGraphFactory(
      "plocal:C:/Users/USER/Desktop/orientdb/databases/testJ", "admin", "admin"); 
    OrientGraph og = ogf.getTx(); 

    try { 
     System.out.println("Features = " + og.getFeatures()); 
    } finally { 
     og.shutdown(); 
    }
