这是我的班级:

@PersistenceCapable
public class Employee
{

    }

    @PersistenceCapable
    @EmbeddedOnly
    public static class ContactInfo
    {
        @Persistent
        private String streetAddress;

        @Persistent
        private String city;

        public ContactInfo(String streetAddress, String city)
        {
            this.streetAddress = streetAddress;
            this.city = city;
        }

        public String getStreetAddress()
        {
            return this.streetAddress;
        }

        public String getCity() …
