안녕하세요, 저는 Spring에 매우 익숙하며 Spring RESTApi를 사용하여 웹 서비스를 작성하고 있습니다. 모델을 제품 및 컨트롤러로 Main으로 작성했으며 주 컨트롤러에서 Product 참조를 선언했습니다. 예외를 따르는 이유는 무엇입니까? 이 문제를 해결하기 위해 제발 도와주세요 ..스프링 컨트롤러가 작동하지 않습니다.
@Controller
public class Main {
@Autowired
private Product product;
@RequestMapping(method = RequestMethod.GET, value = "/product/{id}")
public @ResponseBody
Product getProoduct(@PathVariable long id) {
//Product product = new Product();
product.setId(id);
product.setOwnerName("Android");
product.setProductName("Gah");
return product;
}
}
public class Product {
private long id;
private String productName;
private String ownerName;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getProductName() {
return productName;
}
public void setProductName(String productName) {
this.productName = productName;
}
public String getOwnerName() {
return ownerName;
}
public void setOwnerName(String ownerName) {
this.ownerName = ownerName;
}
}

구조가 약간 이상합니다. 제품은 엔티티 개체와 비슷하지만 원할 경우 싱글 톤 Bean이됩니다. 즉, 모든 요청이 동일한 Product 인스턴스에 액세스합니다. – Taylor
나는 product product = new Product()에 댓글을 달았습니다. 주석을 제거하면 매우 잘 작동 할 것이고, 제품 객체를 싱글 톤으로 만들고 싶지는 않지만 의도적으로 Autowired를하고 있습니다. – Ani
