-
Select Spring Boot as your framework.
-
Enter your query description in natural language.
-
Instantly receive JPA or SQL code tailored for your use case.
Example Queries
1. JPA Repository Methods
Natural Language: “Find active users who registered in the last 30 days.”
// Generated Repository Method
public interface UserRepository extends JpaRepository<User, Long> {
List
// Usage @Service public class UserService { @Autowired private UserRepository userRepository;
public List<User> getRecentActiveUsers() {
return userRepository.findByActiveAndCreatedAtAfter(
true,
LocalDateTime.now().minusDays(30)
);
}}
2. JPQL Queries
Natural Language: “Get orders with their items and customer details, total over $100.”
// Generated JPQL Query
@Query("""
SELECT DISTINCT o FROM Order o
JOIN FETCH o.orderItems i
JOIN FETCH o.customer c
WHERE (SELECT SUM(oi.price * oi.quantity)
FROM OrderItem oi
WHERE oi.order = o) > 100
ORDER BY o.createdAt DESC
""")
List
3. Criteria API
Natural Language: “Find products with low inventory and high demand.”
// Generated Criteria API Query
public List
demandCount.select(cb.count(orderItem))
.where(cb.equal(orderItem.get("product"), product),
cb.greaterThanOrEqualTo(orderItem.get("createdAt"), since));
cq.select(product)
.where(cb.and(
cb.lessThanOrEqualTo(inventory.get("stockLevel"), inventory.get("reorderPoint")),
cb.greaterThanOrEqualTo(demandCount, threshold)
));
return entityManager.createQuery(cq).getResultList();}

Criteria API for dynamic and complex queries
-
Native SQL for direct database interaction
2. Advanced Optimizations
-
Suggests fetch strategies to avoid N+1 queries.
-
Includes index recommendations for better performance.
-
Generates queries with proper pagination and sorting.
3. Developer-Friendly

Common Use Cases
1. Sales Analysis
Natural Language: “Show monthly sales totals with year-over-year comparison.”
@Query("""
SELECT new com.example.dto.SalesReport(
FUNCTION(‘DATE_FORMAT’, o.createdAt, ‘%Y-%m’) as month,
SUM(o.totalAmount) as revenue,
COUNT(o) as orderCount
)
FROM Order o
WHERE o.createdAt >= :startDate
GROUP BY month
ORDER BY month DESC
""")
List
2. Dynamic Filtering
Natural Language: “Find orders matching multiple dynamic criteria.”
// Specification for dynamic filtering
public class OrderSpecifications {
public static Specification
return (root, query, cb) -> {
List<Predicate> predicates = new ArrayList<>();
if (startDate != null && endDate != null) {
predicates.add(cb.between(
root.get("createdAt"),
startDate,
endDate
));
}
if (status != null) {
predicates.add(cb.equal(
root.get("status"),
OrderStatus.valueOf(status)
));
}
if (minAmount != null) {
predicates.add(cb.greaterThanOrEqualTo(
root.get("totalAmount"),
minAmount
));
}
return cb.and(predicates.toArray(new Predicate\[0\]));
};
}}
Best Practices for Spring Boot Queries
1. Optimize Fetch Strategies
-
Use
fetch = FetchType.LAZYfor associations to load data only when needed. -
Apply
JOIN FETCHin JPQL queries for eager loading.
2. Use Specifications for Complex Filtering
Simplify query logic by creating reusable specifications.
3. Monitor Query Performance
-
Enable Hibernate’s SQL logs for debugging.
-
Use profiling tools like JPA Buddy or Spring Actuator.
