ozayduman/spring-data-specification-builder
Jan 2021 - Aug 2021
Specification-Builder is a client-oriented dynamic search query library that supports joins among multiple tables in a strongly-type manner for Spring Projects. This library simplifies writing type-safe queries for search screens by using `Spring Data JPA`'s `JpaSpecificationExecutor` and `hibernate-jpamodelgen`. As you might know, for each query screen you have to pass a specific DTO (Data Transfer Objects) and write specific queries using that DTO. This leads to boiler-plate, useless, repetitive code. By using this library you can get rid of that kind of code, and write fluent-style dynamic queries driven by client-side easily.
