Spring data neo4j: How to append dynamic @Query？

How to generate dynamic value of @Query when have complex queries in Neo4jRepository ? Like:

@Repository
public interface StockRepository extends Neo4jRepository<StockNode,Long> {

     @Query("match (n:stock) where n.name={aShareShortName} return n")
    List<StockNode> getStockNodeByAShareShortName(@Param("aShareShortName") String aShareShortName);

    @Query("match (n:stock) where n.{indexName}={indexContent} return n")
    List<StockNode> getStockNodeByQueryProperty(@Param("indexName")String indexName,String indexContent);

}

The first method getStockNodeByAShareShortName is Ok. But the second getStockNodeByQueryProperty is failed. Is there any method to generate dynamic property keys in n.{xxx} or n.?1 or n.:xx ?

for creating dynamic property or dynamic query you need to use session(import org.neo4j.ogm.session.Session;) then you can create dynamic query and append your where condition

String query="match (n:stock) where" DYNAMIC_FIELD+"=" +VALUE session.query(Map.class, query, queryParameters);
