在这里，我将复制我拥有的类和 web.xml.

Here i will copy the classes and web.xml which i have.

@XmlAccessorType(XmlAccessType.NONE)

@XmlRootElement(name = "员工")公共类员工{

@XmlRootElement(name = "employee")public class Employee {

public String empId;
public String name;
public String email;

@javax.xml.bind.annotation.XmlElement(required = true)
public String getEmpId() {
    return empId;
}

public void setEmpId(String empId) {
    this.empId = empId;
}

@javax.xml.bind.annotation.XmlElement(required = true)
public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

@javax.xml.bind.annotation.XmlElement(required = true)
public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

}

@Path("/emp")公共类员工服务{

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

@GET
@Path("/get/{empId}")
public Employee getEmployee(@PathParam("empId") String empId) {
    Employee employee = new Employee();
    employee.setEmpId(empId);
    employee.setName("Nikola");
    employee.setEmpId("nikola@nikola.com");

    return employee;
}

@POST
@Path("/create")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_XML)
public Employee createEmployee(Employee employee) {
    // create logic goes here
    return employee;
}

@PUT
@Path("/update")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Employee updateEmployee(Employee employee) {
    // create logic goes here
    employee.setName(employee.getName() + "updated");
    return employee;
}

@DELETE
@Path("/delete/{empId}")
public javax.ws.rs.core.Response deleteEmployee(@PathParam("empId") int empId) throws URISyntaxException {
    return javax.ws.rs.core.Response.status(200).entity("Employee with " + empId + "is deleted successfully").build();
}
