FindByStatusAnd

FindByStatusAnd is a naming convention used in Spring Data repositories to derive query methods from method names. It enables the framework to generate a database query automatically based on the specified entity properties. The pattern uses the And keyword to combine multiple conditions with a logical AND, allowing developers to express complex queries through the method name alone.

How it works and syntax

A repository method that begins with findBy is followed by one or more property expressions joined with And or Or. Each expression corresponds to a field or a nested property of the entity. The order of the parameters in the method signature matches the order of the properties in the name. For example, a method like ListTask findByStatusAndPriority(Status status, int priority) would retrieve tasks whose status equals the given status and whose priority equals the given priority. Nested properties can be referenced, such as findByStatusAndAssigneeUsername(String status, String username), which translates to a query that joins the related entities as needed.

Examples

- List<Task> findByStatusAndPriority(TaskStatus status, int priority)

- List<Order> findByStatusAndCustomerId(OrderStatus status, Long customerId)

- User findByStatusAndEmail(String status, String email)

Usage considerations

FindByStatusAnd is best suited for simple, read-only query methods where the properties map directly to database columns or navigable associations. The framework generates JPQL or SQL automatically, but for more complex queries or performance tuning, developers can switch to explicit @Query annotations or custom repository methods. It is also common to combine multiple conditions with And to reflect precise filtering criteria.

Related concepts

This approach is part of Spring Data’s query method derivation feature, which can also use Or, Like, Between, In, and other keywords to express various types of predicates. If derived queries become too intricate, a manual query or criteria API approach may be preferred.
