org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization
提问by
I'm developing spring boot microservicesexample from the link: https://dzone.com/articles/spring-boot-creating. In this project I simply updated the parent dependency to its latest version and other code files are unchanged. I faced the following error when I click http://localhost:8080/order?idCustomer=2&idProduct=3&amount=4
我正在从以下链接开发spring boot 微服务示例：https: //dzone.com/articles/spring-boot-creating。在这个项目中，我只是将父依赖更新为最新版本，其他代码文件不变。单击http://localhost:8080/order?idCustomer=2&idProduct=3&amount=4时遇到以下错误

org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.
[[FATAL] A resource model has ambiguous (sub-)resource method for HTTP method GET and input mime-types as defined by"@Consumes" and "@Produces" annotations at Java methods public java.util.List br.com.alexandreesl.handson.rest.ProductRest.getProducts() and public java.util.List br.com.alexandreesl.handson.rest.CustomerRest.getCustomers() at matching regular expression /. These two methods produces and consumes exactly the same mime-types and therefore their invocation as a resource methods will always fail.; source='org.glassfish.jersey.server.model.RuntimeResource@14c14bf']

Please guide on this issue.
请指导这个问题。

I was able to solve this issue. you need to make some changes in mapping request URL. I wonder how code in the block is working without error.
我能够解决这个问题。您需要对映射请求 URL 进行一些更改。我想知道块中的代码是如何正常工作的。
As per my understanding one possible cause is that you have two or more applicable mappings for that URL call. CustomerRest.javaand ProductRest.javaboth were mapped to /.
根据我的理解，一个可能的原因是您有两个或多个适用于该 URL 调用的映射。CustomerRest.java并且ProductRest.java两者都映射到/.
@Path("/")
And
和
@Path("/")
The Jerseyhave no way of telling what method is actually supposed to be called and gives this error.
在Jersey没有告诉什么方法实际上应该被称为并给出了此错误的方式。
You need to correct following files: OrderRest.java
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;
}
}
In CustomerRest.java- use this
在CustomerRest.java- 使用这个
@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;
}
In ProductRest- use this
在ProductRest 中- 使用这个
@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;
}
Here is the output:
这是输出：
