I've migrated an entire project to reactive WebFlux, the only missing thing is the DB queries. At the moment I'm using JdbcTemplate and Hikari Datasources and I need to make DB calls reactive?
I tried to use vertx-db2-client but it seems it does not work fine with Webflux (or I'm not capable to use it correctly).
What options do I have? Can you show any working example with Webflux and DB2?
Thanks
You would need to find that the database DB2 is supported by Spring data reactive libraries. When I look at https://spring.io/projects/spring-data-r2dbc I don't see DB2 being in the list of database they support.
i managed to connect my spring boot application with postgres without hibernate, but with r2dbc for a reactive application.
I was wondering if i can connect spring boot to oracle database without hibernate for a non reactive application ?
Spring Data provides two basic modules for integrating applications with relational databases. Spring Data JDBC is for imperative applications while Spring Data R2DBC is for reactive ones. They both use the same interfaces and patterns. If you're familiar with Spring Data R2DBC, it will be straightforward to work with Spring Data JDBC.
Does cockroachdb support spring reactive api?
I know none of the relational data base support reactive api as they are blocking calls.
is coachroach DB any different?
Yes, CockroachDB supports Spring reactive API. Under the hood, CockroachDB relies on PostgreSQL Java drivers to connect to applications. So, if there is a Java driver that works with Spring reactive and Postgres, it will work with CockroachDB too.
I am trying to understand and get some information for the Hybris platform. Does it use Spring Framework? Also could anyone please share the link / material to have more understanding about it's architecture, technology, etc ?
As per my research, they use:
Technology:
Spring MVC, JSF (FrontEnd), REST Web services ?????
User Interfaces:
Product Cockpit, CMS Cockpit, Print Cockpit, Admin Cockpit, HMC
Platform:
Persistance, Caching, Security, Internationalization, Import/Export, Search
App Server:
Hybris Server, Oracle BEA, IBM, JBoss
Database:
Oracle, SqlServer, Mysql
IMP: Does SAP Hybris support for Spring REST. I think since it uses Spring MVC + Security, so restful web services should of Spring REST only. I heard that it also support RestEasy and Jersey, but not good option when you have a Spring REST in place which adds great support than RestEasy and Jersey. Can you bring in details ?
Can someone please answer to the above IMP query ? Also please share sample RestFul web service of SAP Hybris.
Hybris uses the following technologies:
Java, Spring, Apache SOLR, Groovy, Scala, Apache Commons, ZK framework, Google Analytics, Jasper Reports, Tomcat.
You can find the best information on the architecture of hybris here.
You need a SAP Hybris login for this.
Spring core, Spring MVC.
JSP, javascript, CSS, bootstrap for the frontend.
java 8 for the backend.
apache Solr as the search engine.
tomcat, spring tc server, oracle, IBM as server.
hsqldb, oracle, IBM SAP HANA, MySql, Percona etc as database.
hybris does use spring and many other frameworks (like zk, groovy, scala). They have there own persistence layer and they does use the MVC pattern a lot. As hybris provide a lot of different services and interfaces it is not clearly only one architecture.
e.g. the "datahub" is a communication gateway based on spring integration, but Independent from the base platform.
Hybris use spring mvc spring security. it is compatible with Mysql, HANA, Oracle, sqlserver etc. Also it comes with charon api which make it easy to interact with yaas platform specially designed to fulfill the requirement of other ecommerce feature. you can access it through following link : click [here]:help.hybris.com
But again it is not free. You can also try on http://www.slideshare.net/
I am writing a rest service using Jersey. The data access layer will be developed using Spring JPA. I will be interested to know how can I pass database properties to the Repository layer.
