This guide provides an overview of options for connecting to Nebula Graph for Java developer.

When developing with this Java driver, please use Java 8 . Depending on the version of Nebula Graph that you are connecting to, you will have to use a different version of this client.

When using Maven, add this to your pom.xml file:

<dependency>
    <groupId>com.vesoft</groupId>
    <artifactId>client</artifactId>
    <version>${VERSION}</version>
</dependency>

change ${VERSION} here. For more versions, please refer to releases.

Connect to the graphd:

GraphClient client = new GraphClientImpl("127.0.0.1", 3699);
client.connect("user", "password");

Use a space:

int code = client.switchSpace("space_test");

Execute a query:

int code = client.execute("CREATE TAG course(name string, credits int);");

If query executes seccuessfully, 0 will be returned. For a more complete example, refer to Graph Java client example.
