You need to ensure that APOC library is installed in your Neo4j server. Please follow this installation procedure.
<pre><code> https://neo4j.com/labs/apoc/4.0/installation/#neo4j-server

Then update your conf file to whitelist that function.

Part 1: This is just a warning. In most cases you would not be happy with unbound relationships because the paths can quickly grow in numbers and the server has to keep all possible combination in memory before you will get it.
Part 2: What @jose_bacoy says. Behind the link are informations about how to add APOC in Desktop, Server or Docker deployment. Test your query (or even a reduced version of it) in the shell/browser to ensure it is activated correctly.
Part 2 (again but different topic): You cannot return <code>PathValue</code> in a repository. If you want to use the Java driver's type, please use SDN's <code>Neo4jClient</code> for interaction. <a href="https://docs.spring.io/spring-data/neo4j/docs/current/reference/html/#neo4j-client" rel="nofollow noreferrer">SDN documentation / Neo4jClient</a>
(Edit and added)
Docker compose:
I could not make it work to provide an array with the other syntax, so basically this will auto-load the plugin on container start.
You can check if the APOC library is available via <code>CALL dbms.procedures()</code> in the shell or browser.
This is what you should do first.

I have a problem about calculating the shortest path through Neo4j in my Spring Boot example.
After adding some cities with its route, I want to calculate their shortest path in terms of their connection and their duration. However, these two methods which defined in ShortestPathController cannot work.
Here are the issues shown below.
Edited
1 ) I cannot run all test methods in AppApplicationTests.java
<pre><code>org.neo4j.driver.exceptions.AuthenticationException: The client is unauthorized due to authentication failure.
</code></pre>
2 ) I have no idea as I cannot run all test methods what if there are many cities and its route like this resource (<a href="https://vladbatushkov.medium.com/one-month-graph-challenge-hero-city-cc4ffa51bb1b" rel="nofollow noreferrer">Link</a>)
How can I fix it?
Here is my GitHub repository : <a href="https://github.com/Rapter1990/SpringBootNeo4jShortestPath" rel="nofollow noreferrer">Project Link</a>

在Spring示例中，我在计算通过Neo4j的最短路径时遇到了问题。在添加了一些城市的路线之后，我想根据它们的连接和持续时间来计算它们的最短路径。但是，在ShortestPathController中定义的这两种方法不能工作。下面是如下所示的。编辑过的AppApplicationTests.java中的1 ) I不能运...
