Question

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

显示错误

HTTP状态500 - 处理程序处理失败;嵌套异常是java.lang.NoClassDefFoundError：com / orientechnologies / orient / core / db / record / ODatabaseRecord

我的依赖..

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

ODatabaseRecord似乎已从新版本弃用。我对您的代码进行了以下更改，并且工作正常（删除所有其他依赖项）。

<强> 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();
    }

注意：我找到了线索here。
