我在使用 Spring LDAP 模板更改密碼時遇到問題。我不使用 Spring 安全性。我通過示例創建了應用程序，并嘗試編寫一個更改用戶密碼的新方法。我們吃：@Data@AllArgsConstructor@NoArgsConstructor@ToString(exclude = "uid")public class Person {    private String uid;    private String fullName;    private String lastName;    private String password;    public Person(String uid, String fullName, String lastName) {        super();        this.fullName = fullName;       this.lastName = lastName;    }}帶有方法的存儲庫：@Servicepublic class PersonRepository implements BaseLdapNameAware {    @Autowired    private LdapTemplate ldapTemplate;    private LdapName baseLdapPath;    public void setBaseLdapPath(LdapName baseLdapPath) {        this.baseLdapPath = baseLdapPath;    }    public Person findOne(String uid) {        Name dn = LdapNameBuilder.newInstance(baseLdapPath).add("ou", "people").add("uid", uid).build();        return ldapTemplate.lookup(dn, new PersonContextMapper());    }    public List<Person> findByName(String name) {        LdapQuery q = query().where("objectclass").is("person").and("cn").whitespaceWildcardsLike(name);        return ldapTemplate.search(q, new PersonContextMapper());    }    public void update(Person p) {        ldapTemplate.rebind(buildDn(p), null, buildAttributes(p));    }    public void updateLastName(Person p) {        Attribute attr = new BasicAttribute("sn", p.getLastName());        ModificationItem item = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, attr);        ldapTemplate.modifyAttributes(buildDn(p), new ModificationItem[] { item });    }    public void updatePassword(Person p) {        Attribute attr = new BasicAttribute("password", p.getPassword());        ModificationItem item = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, attr);        ldapTemplate.modifyAttributes(buildDn(p), new ModificationItem[] { item });    }    private Name buildDn(Person p) {        return LdapNameBuilder.newInstance(baseLdapPath).add("ou", "people").add("uid", p.getUid()).build();    }請幫我用這個方法。如何更新該密碼？
