这是我的班级 EmployeeService

@Path("/emp")
public class EmployeeService {

    @GET
    @Path("/get{empID}")
    @Produces(MediaType.APPLICATION_XML)
    public Employee getEmployee(@PathParam("empID") String empID)
    {
        Employee employee= new com.rest.employee.model.Employee();
        employee.setEmpID(empID);
        employee.setName("Alvin");
        employee.setEmail("test@pmti.biz");
        return employee;
    }

    @POST
    @Path("/create")
    @Consumes(MediaType.APPLICATION_XML)
    @Produces(MediaType.APPLICATION_XML)
    public Employee CreateEmployee(Employee employee)
    {       
        //add logic
        return employee;
    }

    @PUT
    @Path("/update")
    @Consumes(MediaType.APPLICATION_XML)
    @Produces(MediaType.APPLICATION_XML)
    public Employee UpdateEmployee(Employee employee)
    {       
        employee.setName(employee.getName() + " Updated");
        return employee;
    }

    @DELETE
    @Path("/delete/{empID}")
    public Response deleteEmployee(@PathParam("empID") int empID) throws URISyntaxException
    {
        return Response.status(200).entity("Employee with" + empID + " is Deleted Successcully").build();

    }
}

员工类

@XmlAccessorType(XmlAccessType.NONE)
@XmlRootElement(name="employee")
public class Employee {
    public String empID;
    public String name;
    public String email;
    @XmlElement(required=true)
    public String getEmpID() {
        return empID;
    }
    public void setEmpID(String empID) {
        this.empID = empID;
    }

    @XmlElement(required=true)
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;

    @XmlElement(required=true)
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }

Jersey 使用类中的 @Provider 注释来识别 REST 资源（或服务）。也许您的 REST 服务类都没有此注释。
