Répétez cette opération pour créer un autre Bean nommé Customers à l'aide du code suivant :
package beans; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; /** * <p>Java class for anonymous complex type. * * <p>The following schema fragment specifies the expected content contained within this class. * * <pre> * <complexType> * <complexContent> * <restriction base="{http://www.w3.org/2001/XMLSchema}anyType"> * <sequence> * <element name="customer" type="{http://talend.org//services/esb/registry/soap/2012/09}customer" maxOccurs="unbounded" minOccurs="0"/> * </sequence> * </restriction> * </complexContent> * </complexType> * </pre> * * */ @XmlAccessorType(XmlAccessType.PROPERTY) @XmlRootElement(name = "customers") public class Customers { private Map<Long, Customer> customers = new HashMap<Long, Customer>(); private long currentId = 1; public static class Entry extends Customer { public Long id; } public Customers() { }; /** * Gets the value of the customer property. * * <p> * This accessor method returns a reference to the live list, * not a snapshot.
