Question

以下是 iam 用于将 Java 对象作为 XML 返回的代码片段：

@Path("employeeinfo")
@Produces(MediaType.APPLICATION_XML)
public class MyResource {
    
    @GET    
    public Employee getEmployee(@Context Request r) {
        Employee emp = new Employee();
        emp.setName("Name");
        emp.setAge(30);
        emp.setPlace("place");
        
        return emp;
    }

员工类是：

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name= "emp")
public class Employee {
    public Employee() {}    
    private String name;
    private int age;
    private String place;
}

POM xml 是

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

就设置而言，一切都很好，但是当我评估邮递员的服务时，我得到了错误

"SEVERE: MessageBodyWriter not found for media type=application/xml, type=class rest.learning.Employee, genericType=class rest.learning.Employee."

我无法在这里检测到错误。我搜索了所有互联网但没有找到任何答案
