PlaneFinderService.java, line 24.

Sorry, bad news. There's a huge show-stopper bug in the book. The last seven chapters are built around examples of manipulating a data feed from Planefeeder. But nobody can access that feed, except contributors of the data (such as yourself). In the sample code for the book, which I downloaded from the O'Reilly website, the URL to access the Planefeeder feed is hard-coded to a device on your home network.

The fix is for you to revise the sample code. Take out the reference to the device in your home. Then, in PlaneFinderService.java, in saveSamplePositions(), after the three hard-coded Aircraft objects, add another 1000 Aircraft objects. Either as Java objects, or as JSON objects from real life, whichever is easier for you. That will give us enough data for a meaningful test of the manual code. (Three records are not enough!)

As for the first five chapters, no problem! They were helpful and I learned a lot from them. Thanks!

Figure 3-3

In the constructor, UUID is referenced but not imported so in VS Code I get an error "UUID cannot be resolved".

```
public Coffee(String name) {
this(UUID.randomUUID().toString(), name);
}
```

If I add `import java.util.UUID;` at the top, my IDE stops complaining. Is this the/a correct solution?

Loving the book so far by the way!

javax.persistence has been renamed to jakarta.persistence. It doesn't exist anymore.

1st paragraph

When I read page 48, I noticed what follows:

> The first thing to do to enable repository support for our application is to define an interface specific to our application by extending a Spring Data Repository interface: .interfaceCoffeeRepo

I don't know what ".interfaceCoffeeRepo" means; is it a typo or is it a convention to express interface? Because I saw a sample code, here it is:

> interface CoffeeRepository extends CrudRepository<Coffee, String> {}

The interface name is "CoffeeRepository", not "interfaceCoffeeRepo".

"The results" paragraph

In order to run the example, the redis-server needs to be installed and running.
Otherwise the app is failing to start because it can't connect to Redis.
