How can I configure to print out query cypher in the console & How can I use The Neo4j Graph Algorithms Library DFS algorithm in Spring boot project

[jayxu688]

I am using Spring boot to build an app with neo4j.

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-neo4j</artifactId>
</dependency>

application.properties

spring.data.neo4j.embedded.enabled=false

Artifact.java

@Data//@ToString、@EqualsAndHashCode、@Getter、@Setter、@RequiredArgsConstrutor
@NodeEntity
public class Artifact implements Serializable {

    @ApiModelProperty(hidden = true)
    private Long id;

    @ApiModelProperty(example = "uk.neo4j.graph")
    private String groupId;

    @ApiModelProperty(example = "neo4j-graph")
    private String artifactId;

    @ApiModelProperty(example = "1.0")
    private String version;

    @ApiModelProperty(example = "true")
    private Boolean availability;

    @Relationship(type = "DEPEND_ON")

DependOn.java

@Data
@RelationshipEntity(type = "DEPEND_ON")
public class DependOn implements Serializable {


    @Id private Long id;

    @StartNode private Artifact from;

    @EndNode private Artifact to;

    private String scope;

How can I configure to print out query cypher in the console?

Moreover, How can I use the DFS algorithm in graph data science (gds) in the spring boot project?
I hope to use the DFS algorithm to find out whether the artifact currently being queried (that is, the dependency in the maven pom) has been used in other projects released by the company.

For example, log4j2:1.2 has been used in other projects released by the company. I want to query whether there are any projects that the current company has released that depends on log4j2:1.2 in the graph database.

Here is the cyher that I wrote before, but my graph database has over 2 millions of nodes and 10 M of relationships, so the query performance is bad

MATCH (connected)-[:DEPEND_ON*]-> (root:Artifact {gav: "com.twitter:finagle-core_2.11:6.25.0"})
WHERE root <> connected
RETURN distinct connected,root

So I want to query through the DFS algorithm, but I don’t know how to integrate the DFS algorithm in gds into spring boot project.
