请就这个问题提供指导。

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工作而没有错误的

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("/")

及

Jersey

无法判断实际应该调用什么方法，并给出了此错误

您需要更正以下文件： OrderRest.java

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

在CustomerRest.java中使用

@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;
    }

@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;
    }

在ProductRest中-使用此

@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;
    }

@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;
    }
