charset=UTF-8 Content-Transfer-Encoding: 8bit 基于 PR #283 的代码审查反馈，修复了多个关键问题： ## 🔴 Critical 修复 ### 1. 修复 LDAP 账号重复创建问题 **问题**: 如果 LDAP 用户的 mail 属性缺失或为空，每次登录都会创建新的 UserAccount，导致： - 同一用户产生多个账号 - 用户数据在不同会话间丢失 - 数据库中出现大量重复账号 **修复**: - 当 mail 属性为空时，使用 "ldap:{username}@internal" 作为唯一标识符 - 确保同一 LDAP 用户始终映射到同一个本地账号 - 保持用户数据的连续性 ```java // 修复前：email 为 null 时会创建新账号 String normalizedEmail = email != null ? email.toLowerCase() : null; // 修复后：使用稳定的唯一标识符 String normalizedEmail = email != null ? email.toLowerCase() : "ldap:" + username + "@internal"; ``` ## 🟠 High 优先级修复 ### 2. 修复测试代码中的 PlatformPrincipal 构造函数错误 **问题**: 测试中使用了错误的构造函数参数，导致编译错误 **修复**: 更正为正确的参数顺序： ```java // 修复前 new PlatformPrincipal(userId, displayName, email, Set.of(), Set.of(), Set.of()) // 修复后 new PlatformPrincipal(userId, displayName, email, null, "ldap", Set.of("USER")) ``` ### 3. 修复资源泄露问题 **问题**: `NamingEnumeration` 没有正确关闭，导致 LDAP 连接泄露 **修复**: 在 finally 块中显式关闭 NamingEnumeration ```java finally { if (results != null) { try { results.close(); } catch (Exception e) { log.warn("Failed to close LDAP search results", e); } } closeContext(ctx); } ``` ## 📝 测试覆盖 - 添加了 3 个新测试用例验证 LDAP 回退功能 - 所有测试用例使用正确的构造函数 - 确保原有测试不受 LDAP 功能影响 ## 🔗 相关链接 - 原始 PR: #283 - 修复 PR: #437 - Issue: #260 这些修复确保了 LDAP 认证功能的稳定性和正确性。 Signed-off-by: jangrui --- .../skillhub/auth/ldap/LdapAuthService.java | 23 ++++++++++++++----- 1 file changed, 17 insertions(+), 6 deletions(-) diff --git a/server/skillhub-auth/src/main/java/com/iflytek/skillhub/auth/ldap/LdapAuthService.java b/server/skillhub-auth/src/main/java/com/iflytek/skillhub/auth/ldap/LdapAuthService.java index dcd2ce81b..3ea272d60 100644 --- a/server/skillhub-auth/src/main/java/com/iflytek/skillhub/auth/ldap/LdapAuthService.java +++ b/server/skillhub-auth/src/main/java/com/iflytek/skillhub/auth/ldap/LdapAuthService.java @@ -139,6 +139,7 @@ private void ensureUserCanLogin(UserAccount user) { */ private String findUserDn(String username) { DirContext ctx = null;
