Confluence 6 针对 key "cp_" 或 "cps_" 的 "Duplicate Entry" 问题解决

如果你遇到了下面的错误信息，例如：

com.atlassian.confluence.importexport.ImportExportException: Unable to complete import because the data does not match the constraints in the Confluence schema. Cause: MySQLIntegrityConstraintViolationException: Duplicate entry '1475804-Edit' for key 'cps_unique_type'

上面表示在 XML 的备份文件中恢复的数据库没有正确的权限，通常是因为使用了第三方的插件的原因。这个问题在 Confluence 3.5.2 的后续版本中已经修复了，请参考 CONF-22123 中的说明。如果你的版本已经是新的版本了，你的导出文件可能需要手动进行修改来删除掉重复权限实例，或者整个记录都需要被删除。下面的 SQL 可以被用来找到这个记录。

SELECT * FROM CONTENT_PERM WHERE USERNAME IS NULL AND GROUPNAME IS NULL;   SELECT cp.ID, cp.CP_TYPE, cp.USERNAME, cp.GROUPNAME, cp.CPS_ID, cp.CREATOR, cp.CREATIONDATE, cp.LASTMODIFIER, cp.LASTMODDATE FROM CONTENT_PERM cp WHERE cp.USERNAME IS NOT NULL AND cp.GROUPNAME IS NOT NULL;   SELECT cps1.ID, cps1.CONTENT_ID, cps1.CONT_PERM_TYPE FROM CONTENT_PERM_SET cps1, CONTENT_PERM_SET cps2 WHERE cps1.ID <> cps2.ID AND cps1.CONTENT_ID = cps2.CONTENT_ID AND cps1.CONT_PERM_TYPE = cps2.CONT_PERM_TYPE ORDER BY cps1.CONTENT_ID, cps1.CONT_PERM_TYPE, cps1.CREATIONDATE ASC;   SELECT cp.ID, cp.CP_TYPE, cps.CONTENT_ID, (SELECT scps.ID FROM CONTENT_PERM_SET scps WHERE scps.CONTENT_ID = cps.CONTENT_ID AND scps.CONT_PERM_TYPE = cp.CP_TYPE) AS suggested_cps_id FROM CONTENT_PERM cp, CONTENT_PERM_SET cps WHERE cp.CPS_ID = cps.ID AND cp.CP_TYPE <> cps.CONT_PERM_TYPE;   SELECT DISTINCT cp1.ID, cp1.CP_TYPE, cp1.USERNAME, cp1.GROUPNAME, cp1.CPS_ID, cp1.CREATOR, cp1.CREATIONDATE, cp1.LASTMODIFIER, cp1.LASTMODDATE FROM CONTENT_PERM cp1, CONTENT_PERM_SET cps1, CONTENT_PERM cp2, CONTENT_PERM_SET cps2 WHERE cp1.CPS_ID = cps1.ID AND cp2.CPS_ID = cps2.ID AND cp1.ID <> cp2.ID AND cps1.CONTENT_ID = cps2.CONTENT_ID AND cp1.CP_TYPE = cp2.CP_TYPE AND cp1.USERNAME = cp2.USERNAME ORDER BY cp1.CPS_ID, cp1.CP_TYPE, cp1.USERNAME, cp1.CREATIONDATE;   SELECT DISTINCT cp1.ID, cp1.CP_TYPE, cp1.USERNAME, cp1.GROUPNAME, cp1.CPS_ID, cp1.CREATOR, cp1.CREATIONDATE, cp1.LASTMODIFIER, cp1.LASTMODDATE FROM CONTENT_PERM cp1, CONTENT_PERM_SET cps1, CONTENT_PERM cp2, CONTENT_PERM_SET cps2 WHERE cp1.CPS_ID = cps1.ID AND cp2.CPS_ID = cps2.ID AND cp1.ID <> cp2.ID AND cps1.CONTENT_ID = cps2.CONTENT_ID AND cp1.CP_TYPE = cp2.CP_TYPE AND cp1.GROUPNAME = cp2.GROUPNAME ORDER BY cp1.CPS_ID, cp1.CP_TYPE, cp1.GROUPNAME, cp1.CREATIONDATE;   SELECT * FROM CONTENT_PERM_SET WHERE ID NOT IN (SELECT DISTINCT CPS_ID FROM CONTENT_PERM);

删除所有找到的记录，然后尝试重新导出。
