java - neo4j 休息 API 不工作

Question

neo4j java-rest-binding API 出现问题

git clone https://github.com/neo4j/java-rest-binding
mvn clean package

然后得到了我的 JAR。

尝试过这个:

import org.neo4j.rest.graphdb.RestAPI;
import org.neo4j.rest.graphdb.RestAPIFacade;
import org.neo4j.rest.graphdb.entity.RestNode;
import org.neo4j.rest.graphdb.query.RestCypherQueryEngine;
import org.neo4j.rest.graphdb.util.QueryResult;
import static org.neo4j.helpers.collection.MapUtil.map;

import java.util.Map;

public class Connect {
    public static void main(String[] args) {
        System.out.println("starting test");
        RestAPI api = new RestAPIFacade("http://localhost:7474/");
        System.out.println("API created");
        final RestCypherQueryEngine engine = new RestCypherQueryEngine(api);
        System.out.println("engine created");

        QueryResult<Map<String,Object>> result = engine.query("start n=node({id}) return n", map("id",1));

        System.out.println("query created");
        System.out.println(result);


    for (Map<String, Object> row : result) {
        Object tagline = row.get("tagline");
        long id=((Number)row.get("id")).longValue();
        System.out.println("id is " + id);
        System.out.println(row.get("myRow"));
        }
   }
}

添加了 Neo4j Rest 和嵌入式库并收到此错误消息。 (顺便说一句，我已经检查过，有一个节点 1 并且服务器在本地运行)

开始测试

有什么想法吗？

您可能会有一堆 jars 作为依赖项包含在内。 将其余绑定(bind)包含为 Maven 依赖项当然可以解决它:

org.neo4j
neo4j-rest-graphdb
1.8.1

如果您是从源代码构建的，那么我通常会做不科学的事情:查看 pom.xml https://github.com/neo4j/java-rest-binding/blob/master/pom.xml并从/target/dependencies 中挑选依赖项
