Does Neo4j have a function or plugin that works like SQL's Triggers and can use in java program?

Hi, I'm developing a Java program, I hope it can achieve synchronization between MySQL databases and Neo4j databases. When user changes the schema or matadata in MySQL databases, it can synchronously reflect on Neo4j. I have already achieve this function using SQL's Trigger.
And I want to know is there a similar function in neo4j? When I edit the gragh, change nodes properties, delete or create nodes and relationships, can I customize codes in java that helps me synchronize these changes in MySQL?
Thank you for answering.
