REST API call: Missing URI template variable 'productoId' for method parameter of type Long - spring

Question

Im trying to do a query in Spring boot to database (http://localhost:8180/products/2) and the server responds with:
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Thu Oct 26 01:29:12 COT 2017 There was an unexpected error
(type=Internal Server Error, status=500). Missing URI template
variable 'productoId' for method parameter of type Long
This the interface
package com.beitech.orders.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import com.beitech.orders.model.Product;
public interface ProductJpaRepository extends JpaRepository<Product, Long> {
Product findByProductoId(Long productoId);
#Query(value = "SELECT * FROM PRODUCT WHERE PRODUCTO_ID = ?1", nativeQuery = true)
Product findByproductoId3(Long productoId);
}
This is the controller:
package com.beitech.orders.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.beitech.orders.model.Product;
import com.beitech.orders.repository.ProductJpaRepository;
#RestController
#RequestMapping("/products")
public class ProductController {
#Autowired
private ProductJpaRepository productJpaRepository;
#GetMapping(value = "/allProducts")
public List<Product> findAll(){
return productJpaRepository.findAll();
}
#GetMapping(value = "/{productId}")
public Product findByProductoId(#PathVariable final Long productoId){
return productJpaRepository.findByProductoId(productoId);
}
}

Answer 1

You defined
#GetMapping(value = "/{productId}")
#PathVariable final Long productoId){
There is a mismatch there between productId and productoId. If you want productId to be bound to Long productoId then you would have to declare #PathVariable(name="productId") or alternatively just rename productoId to productId or vice versa.
