A repository method must throw UnsupportedOperationException if it has:

• more than one parameter of type PageRequest or Limit,
• a parameter of type PageRequest and a parameter of type Limit,
• a parameter of type PageRequest or Limit, in combination with the keyword First, or
• more than one parameter of type Order.

Examples:

Invalid example 1

public interface ProductRepository extends DataRepository<Product, Long> { 
    Product findFirstByCategory(String category, Limit limit);  
    //Invalid: First + Limit 
} 

Invalid example 2

public interface ProductRepository extends DataRepository<Product, Long> { 
    List<Product> findAll(Order order1, Order order2);  
    // Invalid: more than one Order 
} 

Valid example

public interface ProductRepository extends DataRepository<Product, Long> { 
    List<Product> findAll(Order order);  
    //Valid: one Order parameter 
}
