在将实体从服务实现类添加到Repository接口时，它显示成功消息但数据未插入数据库我从JpaRepository接口调用save（entity）方法。它没有显示任何错误消息，而是显示记录插入成功消息。
控制器---＆gt;＆gt;。
@Controller
@RequestMapping("/cart")
public class CartController {
@Autowired
CartService cartServices;
/**
* Get All records in Cart
*
* @return All Cart List
*/
@RequestMapping(value = "/list", method = RequestMethod.GET)
public @ResponseBody List<Cart> getCart() {
List<Cart> cartList = null;
try {
cartList = cartServices.getCartList();
if(cartList.isEmpty())
{
System.out.println("List is empty ");
}
} catch (Exception e) {
e.printStackTrace();
}
return cartList;
}
/**

*/
@RequestMapping(value = "/create", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody Status addCart(@RequestBody Cart cart) {
System.out.println("i m from jpa controller");
try {
cartServices.save(cart);
return new Status(1, "Cart added Successfully !");
} catch (Exception e) {

return new Status(0, e.toString());
}

答案 0 :(得分：0)
您是否在rest.xml中添加了以下行
<repositories base-package="com.acme.repositories" />
如果没有尝试添加以上行。它将设置Spring为这些接口创建代理实例。
答案 1 :(得分：0)
您已在rest.xml中定义了Hibernate Session工厂和JPA实体管理器。只使用一个。请参阅以下答案。
