尝试 resttemplate getforobject 时出现 404 错误

Question

I have catalog service that works with product service to get data (microservices). When I try to make getForObject in catalog service, I have an error 404.

    @RestController
    @RequestMapping("/catalog")
    public class ProductCatalogApi {
    @Autowired
    private RestTemplate restTemplate;

    @GetMapping("")
    public String hello(){
        return "Heelloooo";
    }

    @GetMapping("/{category}")
    public void getProductsByCategoryName(@PathVariable String category) {
        UserProduct  userProduct = restTemplate.getForObject(
                "http://shop-product-service/shop/products" + category,
                UserProduct.class);
        System.out.println("dsdasa--------"+ userProduct);
    }

This is my product service:

    @RestController
    @RequestMapping("/shop")
    public class ProductController {
    @Autowired
    ProductRepository productRepository;

    @GetMapping("/all")
    public List<Product> index(){
        return productRepository.findAll();
    }

    @GetMapping("/product/{id_product}")
    public Optional<Product> showByProductId(@PathVariable String id_product){
        return productRepository.findById(id_product);
    }

    @GetMapping("/products/{category}")
    public List<Product> showByCategoryName(@PathVariable String category){
        return productRepository.findByCategory(category);
    }

    }

So when I try to make link this: http://localhost:8082/catalog/electronics , I get error, Please help me.

Answer 1

you lost the character "/" in the class ProductCatalogApi:

restTemplate.getForObject(" http://shop-product-service/shop/products " + category, UserProduct.class);

http://shop-product-service/shop/products => http://shop-product-service/shop/products/
