使用 arangodb java 驱动程序“无权执行此请求”

Question

我想在 Eclipse 上的 Maven 项目中使用 ArangoDB 的 java 驱动程序。 我正在尝试按照此处提供的 ArangoDB 的 Java 驱动程序教程进行操作，但我什至无法让更简单的应用程序工作，即使从一个干净的项目开始。

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>

运行代码时出现以下错误：

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.
Exception in thread "main" com.arangodb.ArangoDBException: Response: 401, Error: 11 - not authorized to execute this request

    at com.arangodb.ArangoDB.createDatabase(ArangoDB.java:437)
    at test.main.main(main.java:12)

我尝试了其他基本操作，但都不起作用（甚至是一个简单的arangoDB.getVersion(); ）。

---

如果我将以下依赖项添加到 pom.xml，它会删除警告而不是错误：

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

结果：

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

您需要指定到您的数据库的连接数据，如用户、密码等，所有数据库需要成功连接，再次检查类Builder 的javadoc 并设置用户和密码。

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

在这里，您什么都不设置，并在没有任何连接数据的情况下构建ArrangoDb实例

我想在Eclipse上的Maven项目中为ArangoDB使用Java驱动程序。 我正在尝试按照此处提供的ArangoDB Java驱动程序教程进行操作，但是即使从一个干净的项目开始，我什至无法使更简单的应用程序正常工作。

main.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"
