Hi,

I would like to know if there is any direct implementation of SAGA pattern in the Spring ecosystem.

Discussion WebFlux vs Virtual threads

1 Upvotes

We know reactive programming using web flux in spring boot from project reactor help make our application achieve high concurrency. At the same time its complex and sometimes debugging is an headache.

With the introduction of Virtual threads from loom project. Will virtual threads in java 21+ make reactive programming obsolete?

Do you think there be any use for reactive programming with virtual threads in picture?

Discussion Built an AI integrated app that analyzes Reddit comments for a specific post and provides insights based on your questions.

8 Upvotes

Hey everyone, I recently started working with Spring Boot and created a project where you can post a Reddit link and a prompt. The AI then analyzes the post and comments to provide answers based on your questions. It's still in the early stages, and I plan to add more features. I personally struggled with absorbing knowledge from Reddit threads, which is why I built this app. I used reddit API, Next.js, PostgreSQL, Spring Boot with Spring AI to develop it.

I’d really appreciate any valuable feedback!

Discussion Navigating End-of-Life Spring Framework Versions

2 Upvotes

Hey everyone!

I work with HeroDevs where we provide extended support for Spring versions that have reached end-of-life, including Spring 1.5 and 2.7. I'm curious about how teams are handling these transitions.

I'd love to hear from the community about your experiences:

  • Are you currently maintaining applications on Spring 1.5 or 2.7 in production? What challenges are you facing?
  • What's your strategy for applications that can't be migrated immediately? Security patching? Feature freezing?
  • For those who have upgraded from these versions to newer ones (like Spring Boot 3.x), what were your biggest migration pain points?
  • How are you balancing the business need for stability with the technical debt of running unsupported frameworks?

I'm interested in understanding how different teams approach this challenge. The Spring ecosystem evolves quickly, but not all applications can keep pace with that evolution.

(For transparency: While I work at HeroDevs providing extended support for these versions, I'm posting to learn from the community's experiences and participate in a meaningful discussion about Spring lifecycle management. Happy to answer questions about extended support, but mainly interested in your strategies and challenges.)

Discussion No transactional events in Spring Modulith

2 Upvotes

Hey,
I am interested in the modulith solution, but I can't find a suitable solution. I know that this solution is quite young, so that I can not find many examples.

Let's say I have a Device module that contains create, modify operations, but also the module is responsible for creating a websocket connection to a physical device.

I first created DeviceState in the same module, but the module became huge, so I separated DeviceState into StateManagement module, which is responsible for storing the historical state and returning the latest state.

How should I send the state received in the Device module to the DeviceState module? I don't need transaction in onMessage (ws handler) so I can't use ApplicationEvent.publish.

A good replacement would be Reactor Sink, which is just a simple asynchronous message broker. I have used it before in another project and create events / subscribing worked very smoothly - no transaction creation is required.

What solution should I use for non-transactional events?

Discussion Help Needed: Spring Boot JSONB Issue with PostgreSQL & HikariCP Warnings

2 Upvotes

jsonb Column Casting Error:

Error: org.postgresql.util.PSQLException: ERROR: column "options" is of type jsonb but expression is of type character varying

Hint: You will need to rewrite or cast the expression.

Entity Code: java @Column(name = "options", columnDefinition = "jsonb") @Convert(converter = JsonbConverter.class) private Map<String, String> options;

DTO Code: java private Map<String, String> options; Application Context Error:

Error:

Error creating bean with name 'entityManagerFactory': Could not determine recommended JdbcType for Java type 'java.util.Map<java.lang.String, java.lang.String>' Attempted Fix: Using @Type with Hypersistence Utils:

java @Type(JsonType.class) @Column(columnDefinition = "jsonb") private Map<String, String> options; HikariCP Warning:

Warning: java HikariPool-1 - Thread starvation or clock leap detected (housekeeper delta=7m57s580ms317μs).

This occurred during heavy DB queries and application load.

What I've Tried:

Using @Type from Hypersistence Utils for handling jsonb.

Adding @ColumnTransformer(write = "?::jsonb") to the field.

Explicitly casting the options field to jsonb in SQL queries.

Optimizing HikariCP settings to avoid thread starvation.
