Understanding Bean Validation 2.0

Number of pages: 130

Description

Validating data is a common task that Java developers have to do and it is spread throughout all layers (from client to database) of an application. This common practice is time-consuming, error prone, and hard to maintain in the long run. Besides, some of these constraints are so frequently used that they could be considered standard (checking for a null value, size, range, etc.). It would be good to be able to centralise these constraints in one place and share them across layers.

That’s when Bean Validation comes into play.

In this fascicle, you will learn Bean Validation and use its different APIs to apply constraints on a bean, validate all sorts of constraints, write your own constraints and a few advanced topics such as integrating Bean Validation with other frameworks (JPA, JAX-RS, CDI, Spring).

eBook: Understanding LangChain4j

Artificial Intelligence (AI) and Large Language Models (LLMs) are rapidly transforming the way we develop and interact with software applications. Integrating these advanced technologies into Java applications, however, can be a daunting task due to their complexity and the sheer volume of concepts involved. That’s where LangChain4j comes into play. In this fascicle, you will learn LangChain4j, the Java library that simplifies the integration of AI and LLMs into your applications. You will explore the fundamentals of AI, learn the history and evolution of AI models, and understand the core concepts of LangChain4j. From accessing and invoking large language models to manipulating embeddings in vector databases, you will gain hands-on experience through practical examples and code snippets. Additionally, you will discover advanced topics such as Retrieval-Augmented Generation (RAG), debugging, testing, and integrating LangChain4j with other technologies.
