Question

嗨，我是cxf soap Web服务的新手，我在测试此api时创建了一个crud应用程序，但在SOAPUI中收到以下错误消息

<faultstring>object is not an instance of declaring class while invoking public abstract soap.product.pojo.Product soap.product.service.ProductService.getProductById(int) with params [1]</faultstring>

Product.java

        package soap.product.pojo;

    public class Product 
    {   
        private int id;

        private String name;

        private String description;

        private float price;

        public Product(int id, String name, String description, float price) 
        {
            super();
            this.id = id;
            this.name = name;
            this.description = description;
            this.price = price;
        }
