org.glassfish.jersey.server.model.ModelValidationException：应用程序初始化期间应用程序资源模型的validation失败
我正在从链接开发spring boot微服务示例： https ： //dzone.com/articles/spring-boot-creating 。 在这个项目中，我只是将父依赖项更新为其最新版本，其他代码文件保持不变。 当我点击http：// localhost：8080 / order？idCustomer = 2＆idProduct = 3＆amount = 4时遇到以下错误

请指导这个问题。
我能够解决这个问题。 您需要在映射请求URL中进行一些更改。 我想知道块中的代码是如何正常工作的。
根据我的理解，一个可能的原因是您有两个或更多适用于该URL调用的映射。 CustomerRest.java和ProductRest.java都映射到/ 。
@Path("/")
和
@Path("/")
Jersey无法告诉实际应该调用哪种方法并给出了这个错误。
您需要更正以下文件： OrderRest.java
@Named @Path("/") public class OrderRest { private long id = 1; @Inject private RestTemplate restTemplate; @GET @Path("order") @Produces(MediaType.APPLICATION_JSON) public Order submitOrder(@QueryParam("idCustomer") long idCustomer, @QueryParam("idProduct") long idProduct, @QueryParam("amount") long amount) { Customer customer = restTemplate.getForObject("http://localhost:8080/customer/getCustomer?id={id}", Customer.class, idCustomer); Product product = restTemplate.getForObject("http://localhost:8080/product/getProduct?id={id}", Product.class,idProduct); Order order = new Order(); order.setCustomer(customer); order.setProduct(product); order.setId(id); order.setAmount(amount); order.setOrderDate(new Date()); id++; return order; } }
在CustomerRest.java中 – 使用它
@GET @Path("/getCustomer") @Produces(MediaType.APPLICATION_JSON) public Customer getCustomer(@QueryParam("id") long id) { Customer cli = null; for (Customer c : customers) { if (c.getId() == id) cli = c; } return cli; }
在ProductRest中 – 使用它
@GET @Path("/getProduct") @Produces(MediaType.APPLICATION_JSON) public Product getProduct(@QueryParam("id") long id) { Product prod = null; for (Product p : products) { if (p.getId() == id) prod = p; } return prod; }
这是输出：
