使用 arangodb java 驅動程序“無權執行此請求”

Question

我想在 Eclipse 上的 Maven 項目中使用 ArangoDB 的 java 驅動程序。 我正在嘗試按照此處提供的 ArangoDB 的 Java 驅動程序教程進行操作，但我什至無法讓更簡單的應用程序工作，即使從一個干凈的項目開始。

主.java：

package test;

import com.arangodb.ArangoDB;

public class main {

    public static void main(String[] args) {

        ArangoDB arangoDB = new ArangoDB.Builder().build();

        arangoDB.createDatabase("myDatabase");
    }

}

pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>test</groupId>
   <artifactId>test</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <dependencies>
    <dependency>
        <groupId>com.arangodb</groupId>
        <artifactId>arangodb-java-driver</artifactId>
        <version>4.2.0</version>
    </dependency>
  </dependencies>
</project>

運行代碼時出現以下錯誤：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

我嘗試了其他基本操作，但都不起作用（甚至是一個簡單的arangoDB.getVersion(); ）。

---

如果我將以下依賴項添加到 pom.xml，它會刪除警告而不是錯誤：

<dependency> 
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.7.22</version>
</dependency>

結果：

Exception in thread "main" com.arangodb.ArangoDBException: Response: 401, Error: 11 - not authorized to execute this request
    at com.arangodb.internal.velocystream.VstCommunication.checkError(VstCommunication.java:106)

Answer 1

您需要指定到您的數據庫的連接數據，如用戶、密碼等，所有數據庫需要成功連接，再次檢查類Builder 的javadoc 並設置用戶和密碼。

ArangoDB arangoDB = new ArangoDB.Builder().build();

在這里，您什么都不設置，並在沒有任何連接數據的情況下構建ArrangoDb實例

我想在Eclipse上的Maven項目中為ArangoDB使用Java驅動程序。 我正在嘗試按照此處提供的ArangoDB Java驅動程序教程進行操作，但是即使從一個干凈的項目開始，我什至無法使更簡單的應用程序正常工作。

        ArangoDB arangoDB = new ArangoDB.Builder().build();

        arangoDB.createDatabase("myDatabase");
    }

}
