I'm trying to made a search query with a @GetMapping Using JPA and SpringBoot
Here is the controller Method used:
@GetMapping("/search{min_price}{max_price}{text}")
public Optional<Product> searchProducts(@PathVariable(required = false) Integer min_price,
@PathVariable(required = false) Integer max_price,
@PathVariable(required = false) String text
) {
Optional<Product> products = productRepository.SearchProduct(min_price, max_price, text);
return products;
}
And here the @Query that I made in repository: (I Changed the @Param names to ?X and the issue still happens)
@Query("SELECT P FROM Product P " +
"where (P.name like CONCAT('%',lower(?3),'%') or P.description like CONCAT('%',lower(?3),'%')) " +
"and (?2 is null or P.price <= ?2) " +
"and (?1 is null or P.price >= ?1)")
Optional<Product> SearchProduct(@Param("max_price") Integer min_price,
@Param("min_price") Integer max_price,
@Param("text") String text);
I'm using H2 database for the first time, don't know if the ?X is the right way to use the variables in it. (in PL-SQL I use :X for this purpose).
When I made a get the return is always "null" in Postman
this is an example of get that I made "search?min_price=1&max_price=200&text=prod" The database has 5 entries and if I search with this values direct in DB 2 results match the criteria.
