This library brings the convenience of SQL declarative nature to restful APIs in the form of RSQL but without the danger of sql injection by using a typesafe mapping of allowed field paths defined via integration with querydsl library. Like sql, it supports clauses such as select, filter, pagination and sorting that can easily be represented in http request parameters. It primarily supports JPA model and MongoDB query via Querydsl.
