**JDK17 环境变量改为**

下载JDK 17



	wget https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.tar.gz
	
	# 解压安装包
	tar -xzf jdk-17_linux-x64_bin.tar.gz
	 
	# 假设解压到了 /opt/jdk-17 目录下
	 
	# 配置环境变量
	echo 'export JAVA_HOME=/opt/jdk-17' >> ~/.bashrc
	echo 'export PATH=$PATH:$JAVA_HOME/bin' >> ~/.bashrc
	 
	# 刷新环境变量

# Neo4j 基本命令

查看所有node
`match (n) return n`

查询与 id=3 的startNode 相关联的所有的node和relation
`MATCH (startNode)-[r]->(relatedNode)`
`WHERE id(startNode) = 3`
`RETURN startNode, r, relatedNode, type(r) AS relType`

查询与 id=3 的startNode/endNode 相关联的所有的node和relation
`MATCH (startNode)-[r]->(relatedNode)`
`WHERE id(startNode) = 3 or  id(relatedNode) = 3`
`RETURN    startNode, r, relatedNode, type(r) AS relType`

查询与 name=name0 的startNode/endNode 相关联的所有的node和relation
`MATCH (startNode:Person)-[r]->(relatedNode:Person)`
`WHERE startNode.name = 'name0' OR relatedNode.name = 'name0'`
`RETURN startNode, r, relatedNode, TYPE(r) AS relType`
