我已经花了一个月的时间来运行这个程序，但没有找到任何解决方案。 这是一个复制的程序。我只是想在任何方面运行它。 我想把它当作休息服务。它有什么错误吗？

请帮忙。 这就是我项目中的全部内容。

提前谢谢!!

这是我的计划：

Coustomer.java 

package com.abhi.shek.idea.book;

public class Customer {
private int id;
private String firstName;
private String lastName;
private String street;
private String city;
private String state;
private String zip;
private String country;

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public String getStreet() {
    return street;
}

public void setStreet(String street) {
    this.street = street;
}

public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
}

public String getState() {
    return state;
}

public void setState(String state) {
    this.state = state;
}

public String getZip() {
    return zip;
}

public void setZip(String zip) {
    this.zip = zip;
}

public String getCountry() {
    return country;
}

public void setCountry(String country) {
    this.country = country;
  }
}

这是我的另一个课程：

CustomerResource.java

    private AtomicInteger idCounter = new AtomicInteger();

    @POST
    @Path("/create")
    @Consumes("application/xml")
    public Response createCustomer(InputStream is) {
        Customer customer = readCustomer(is);
        customer.setId(idCounter.incrementAndGet());

    @GET

    public StreamingOutput getCustomer(@PathParam("name")String name) {

        if (customer == null) {
            throw new WebApplicationException(Response.Status.NOT_FOUND);
        }
        return new StreamingOutput() {
            public void write(OutputStream outputStream)
                    throws IOException, WebApplicationException {
                outputCustomer(outputStream, customer);
            }
        };
    }

    @PUT

    @Consumes("application/xml")
    public void updateCustomer(@PathParam("id") int id, InputStream is) {
        Customer update = readCustomer(is);
        Customer current = customerDB.get(id);
        if (current == null)
            throw new WebApplicationException(Response.Status.NOT_FOUND);
        current.setFirstName(update.getFirstName());
        current.setLastName(update.getLastName());
        current.setStreet(update.getStreet());
        current.setState(update.getState());
    }

    protected void outputCustomer(OutputStream os, Customer cust)
        throws IOException {
        PrintStream writer = new PrintStream(os);
        writer.println("<customer id=\"" + cust.getId() + "\">");
        writer.println("<first-name>" + cust.getFirstName()

        writer.println("<country>" + cust.getCountry() + "</country>");
        writer.println("</customer>");
        }

    protected Customer readCustomer(InputStream is) {
        try {
            DocumentBuilder builder = DocumentBuilderFactory.newInstance()
                    .newDocumentBuilder();
            Document doc = builder.parse(is);
            Element root = doc.getDocumentElement();
            Customer cust = new Customer();
            if (root.getAttribute("id") != null
            && !root.getAttribute("id").trim().equals("")) {
            cust.setId(Integer.valueOf(root.getAttribute("id")));
            }
            NodeList nodes = root.getChildNodes();
            for (int i = 0; i < nodes.getLength(); i++) {
            Element element = (Element) nodes.item(i);
            if (element.getTagName().equals("first-name")) {
            cust.setFirstName(element.getTextContent());
            }
            else if (element.getTagName().equals("last-name")) {
            cust.setLastName(element.getTextContent());
            }
            else if (element.getTagName().equals("street")) {
            cust.setStreet(element.getTextContent());
            }
            else if (element.getTagName().equals("city")) {
            cust.setCity(element.getTextContent());
            }
            else if (element.getTagName().equals("state")) {

            }
            else if (element.getTagName().equals("zip")) {

            }
            }
            return cust;

        } catch (Exception e) {
            throw new WebApplicationException(e,
                    Response.Status.BAD_REQUEST);
        }
    }
}

这是我的第三个项目：

ShoppingApplication.java 

package com.abhi.shek.idea.book;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
import java.util.HashSet;
import java.util.Set;

@ApplicationPath("/services")
public class ShoppingApplication extends Application {
private Set<Object> singletons = new HashSet<Object>();
private Set<Class<?>> empty = new HashSet<Class<?>>();

public ShoppingApplication() {
    singletons.add(new CustomerResource());
}

@Override
public Set<Class<?>> getClasses() {
    return empty;
}

@Override
    public Set<Object> getSingletons() {
        return singletons;
    }
}

这是我的pom.xml文件：

错误：在控制台上：

SEVERE: Servlet [RestClient] in web application [/JAXRS-RestClient] threw  load() exception
java.lang.ClassNotFoundException:     com.sun.jersey.spi.container.servlet.ServletContainer
at         org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1720)

另一个错误是：

 com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.
at com.sun.jersey.server.impl.application.RootResourceUriRules.<init>    (RootResourceUriRules.java:99)
