I have created my database with java code and using library,So Please check if i turn off the server directly so How i could resume this database when i getting this error on it. 我已经使用Java代码和库创建了数据库，所以请检查是否直接关闭服务器，以便在出现此错误时如何恢复该数据库。

Are you running a second instance of Neo4j on the same directory? 您是否在同一目录上运行Neo4j的第二个实例？

If not make a backup copy of your graphdb directory, remove /var/database/schema/label/lucene/write.lock and retry. 如果未制作graphdb目录的备份副本，请删除/var/database/schema/label/lucene/write.lock试。
