Querydsl and jOOQ are two popular choices

I can recommend jOOQ  It provides a lot of great features  also a intuitive DSL for SQL and a extremly customable reverse-engineering approach      jOOQ effectively combines complex SQL  typesafety  source code generation  active records  stored procedures  advanced data types  and Java in a fluent  intuitive DSL
