Betreff: Re: Evaluating empire-db with Spring Boot
sorry, had a typo: maven does not exist, it is "mvn"
```
$ cd empire-db/empire-db-examples/empire-db-example-spring-boot
$ mvn clean install
$ java -jar target/empire-db-example-spring-boot-2.5.3.jar
```

Hello Ralf,
i tried to get the example working but I am struggeling with the Datasource.
I got a first issue resolved, where the Logger was twice found in the
sourcetree but i think this is a local issue for me.
The issue I currently cannot resolve comes up, as soon as the datasource tries
to get a connection.
It tells me the HikariDatasource is null „HikariDatasource (null)“,
unfortunatly i do not get a Stacktrace.
The error occurs in SampleApp.java:240 as soon as the Connection shall be
fetched in the run() Method.
As Rainer I have not much experience with Spring too, but tried get it working
non the less.
If you can have a look into it and hopefully have a solution for me.
Thanks in advance and have a great weekend
Greetings
Daniel

Betreff: Re: Evaluating empire-db with Spring Boot
Hi Rainer,
I am glad to contribute. The example is without Spring JDBC Templates, just
pure Empire-DB, but configured
over the convenience configuration features of Spring Boot (application.yml,
profiles and reading them with ConfigurationProperties).
The DataSource is automatically instantiated when Spring Boot detects the
hsqldb driver on classpath and when dependency to spring-boot-starter-jdbc is
in pom.xml
and by using standard datasource properties (see
https://docs.spring.io/spring-boot/docs/current/reference/html/application-properties.html#application-properties.data.spring.datasource.url
)
The DataSource uses automatically Hikari-ConnectionPool.
Many greetings
Ralf

Hello Ralf,
thank you very much for your Spring-Boot Example.
We are happy that you are interested in Empire-db and every contribution to our
project is very much appreciated.
We will gladly take a look at the example, but it might take a few days before
we can comment.
Unfortunately I personally do not have experience with Spring Boot and other
Spring related components.
But if I need some help to understand it, I will let you know.
Best Regards,
Rainer

Betreff: Re: Evaluating empire-db with Spring Boot
ok, managed to implement a working spring boot example.
opened a pull request for the new example:

please review if done properly

I have to questions:
1. Is there an example code using empire-db with spring boot?
e.g. using common application properties for connection/database setup
currently I am using jdbi but do not like the "functional programming" row
mapping...
the code example here:
https://github.com/apache/empire-db/tree/master/empire-db-examples/empire-db-example-spring
seems to map empire-db to spring jdbc templates...
but I want a barebones empire-db setup in a spring boot (without jdbc template
- for now)
to get used to it.
any tutorial/documentation beside this one:
http://empire-db.apache.org/documentation/tutorial.htm ?
2. I have JSONB columns in my postgres database. How to handle json functions
with empire-db?
