(十) Java连接JanusGraph 本地调试版（呕心沥血）

原官方文档：https://docs.janusgraph.org/interactions/connecting/java/

我使用的测试代码如下：

package org.example;

import org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversalSource;
import org.junit.Test;

import static org.apache.tinkerpop.gremlin.process.traversal.AnonymousTraversalSource.traversal;

 */
public class GraphTests {

    @Test
    public void test() throws Exception {
        GraphTraversalSource g = traversal().withRemote("conf/remote-graph.properties");
        // Reuse 'g' across the application
        // and close it on shut-down to close open connections with g.close()
        Object herculesAge = g.V().has("name", "hercules").values("age").next();
        System.out.println("Hercules is " + herculesAge + " years old.");
    }
}

起初一直以为是启动cassandra版本有问题，后续不断尝试发现问题所在: (NoHostAvailableException) 害的我好惨

后续通过连接地址发现了排查迹象。

sudo lsof -i tcp:8182

后续发现JanusGraph启动存在问题：检测出现一个scripts/empty-sample.groovy脚本未找到：

这时候发现配置文件中确实存在该文件信息：

起初我以为这个文件没啥作用，便直接删除了files这个配置节点中的信息，再次启动JanusGraph发现出现8182监听了。

至此我以为可以运行起来了，但是发现运行测试工程尝试连接JanusGraph发现还是会出现异常，但是异常消息不一样了：

The traversal source [g] for alias [g] is not configured on the server.

后续翻阅了相关文档，在一篇文章中找到了痕迹；https://jointhegraph.github.io/articles/hosting-multiple-graphs-on-janusgraph/

后续发现实际janusgraph启动会定义这个global map的概念，至此，我将配置信息中的文件地址更改了一下文件指向，指向本地调试下能找到的一个文件路径后，再次启动测试代码，便可以正常调试通过，这个问题折磨了2天，OMG. respect!
