Develop Spring DATA Neo4j Repository. As we discussed earlier, we need to develop only interface by extending Spring DATA Neo4j API interface GraphRepository and not required its implementation. Spring DATA Neo4j will take care of providing implementation for this interface internally What we are going to do in this example is that, we have a student entity. We will create some students and define a seniority relationship and save data. Then using student name we will fetch our data from graph database. We will also run cypher query on Neo4j UI to get the graph for our data at the end. Software Required to Run Example To run the example we need the software as below. 1. JDK.
