neo4j入门教程-java中使用Cypher操作数据库

操作

1. 节点的操作
   
   1. 创建节点Node node1=graphdb.createNode();
   2. 节点添加属性node1.setProperty("message", "Hello");
   3. 获取属性 node1.getProperty("message");
   4. 节点删除node1.delete()
2. 关系的操作
   
   1. 创建 relationship = node1.createRelationshipTo(node2, RelTypes.KNOWS);
   2. 添加属性relationship.setProperty("message", "brave neo4j");

Cypher

1. ExecutionEngine engine = new ExecutionEngine(graphdb); //构造引擎
ExecutionResult result = engine.execute("start n=node(1) return n,n.message"); //执行cypher语句
   返回结果如下：
   
2. 模板如下

package testn
