如何使用java连接orientdb数据库？

Question

我尝试使用orientdb数据库与java连接。这样地 OrientGraph odb = new OrientGraph("plocal:C:/Users/USER/Desktop/orientdb/databases/testJ", "admin", "admin");

这是一个错误

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

我的依赖

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

ODatabaseRecord似乎已从新版本中弃用。我对你的代码做了以下更改，它成功了（删除所有其他依赖项）

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代码

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();
    }
