java - 使用 Java 和 XML 数据库的 CRUD

Question

我正在寻找使用 java 添加、编辑、删除和删除 XML 数据库中的条目。下面的代码包含我的 XML 数据库中条目的所有 getter 和 setter。如何从我的 XML 中获取值到适当的对象中？

public class contact implements Serializable{

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column
private int Id;
@Column
private String firstname;
@Column
private String lastname;
@Column
private String email;

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 getEmail() {
    return email;
}

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

public contact(int Id, String firstname, String lastname, String email) {
    this.Id = Id;
    this.firstname = firstname;
    this.lastname = lastname;
    this.email = email;
}
