Consider a read-only service that needs to do real time searching of a backing database. The service needs to be able to generate fairly complex select queries to generate summaries, reports, and results based on multi-table objects. The priorities for the library/framework selection are performance (of the sql), maintainability, and longevity.

Hibernate – Seems to require “tricks” to get it to generate the correct SQL, The Criteria API looks promising but also has several limitations when it comes to arbitrary queries.

MyBatis – No Criteria-like API but it’s clear and clean and often doesn’t require the tricks and tweeks of Hibernate. Limited database abstraction.

Some other yet-to-be-evaluated solutions include: SQLBuilder, Squiggle, Querydsl, JOOQ, or a custom solution.

What have SO users found works best for making a fast versatile searching service.

[update] – Some of the tricks and issues I have faced with Hibernate are…

In general, joining to the same table twice seems to cause problems. I’ve even managed to trick hibernate into producing the correct SQL only to have it map the results wrong because it cached the first instance of the entity and assumed the columns from the second join where redundant. Conditional joins expressed via annotations is also painful. Not saying it’s impossible but very cryptic and not intuitive.

To answer X-Zero below I am wanting to go from a specification to a result. Ie, the consumer tells me what they know, and I build a query that answers their question on-the-fly. In practice I intend to have some limits on what they can pass in.

    For a query-oriented service I’d strongly recommend to stay away from Hibernate or similar JPA frameworks. MyBatis can be a good choice and it provides some basic scripting support for dynamically constructing queries from SQL fragments, but you’ll have to deal with SQL dialects yourself.

    Also, to add to your list, there are also Spring SQL Template classes and JDBI, though neither of them address issue with SQL dialects.
