我必須從 LDAP 服務(wù)器讀取操作屬性（createTimeStamp、entryUUID 等）。我試圖實(shí)現(xiàn)自己的 UserDetailContextMapper 但沒有成功。目前我的代碼看起來像這樣Overridepublic void configure(AuthenticationManagerBuilder auth) throws Exception {    auth            .ldapAuthentication()            .userSearchFilter("uid={0}")            .groupSearchBase("ou=users")            .userDetailsContextMapper(userContextMapper())            .contextSource(contextSource());}@Beanpublic LdapContextSource contextSource() {    LdapContextSource contextSource = new LdapContextSource();    contextSource.setUrl("ldap://ldap.company.pl:389");    contextSource.setBase("dc=company,dc=com");    contextSource.afterPropertiesSet();    return contextSource;}@Beanpublic UserDetailsContextMapper userContextMapper() {    return new CustomUserDetailContextMapper();}我的 UserDetailContextMapper 實(shí)現(xiàn)：public class CustomUserDetailContextMapper implements UserDetailsContextMapper {@Overridepublic UserDetails mapUserFromContext(DirContextOperations ctx, String username, Collection<?        extends GrantedAuthority> authorities) {    AutoUser user = new AutoUser();    user.setCreateTimeStamp(ctx.getStringAttribute("createTimestamp"));    user.setUUID(ctx.getStringAttribute("entryUUID"));    user.setEmail(ctx.getStringAttribute("mail"));    return user;}@Overridepublic void mapUserToContext(UserDetails user, DirContextAdapter ctx) {    //default impl}}我試過了Attributes attributes = ctx.getAttributes(username, new String[] {"*", "+"});在方法中，但如果我通過了mapUserFromContext()，我就會(huì)收到。NamingExceptionusername我正在考慮實(shí)現(xiàn) ldapTemplate.lookup()，但我不確定在哪里實(shí)現(xiàn)它，我嘗試用 ldapTemplate 做 userRepo 類，但我得到NameNotFoundException了我通過的任何 DN。
