原因：

CM元数据库 字符集不兼容 字段 VALUE  MESSAGE  无法写入对应的值。

解决办法：

修改元数据库。

use  cm_db;

alter table CONFIGS         modify `VALUE` longtext character set utf8 collate utf8_general_ci;
alter table CONFIGS_AUD     modify `VALUE` longtext character set utf8 collate utf8_general_ci;
alter table GLOBAL_SETTINGS modify `VALUE` longtext character set utf8 collate utf8_general_ci;
alter table USER_SETTINGS   modify `VALUE` longtext character set utf8 collate utf8_general_ci;


alter table AUDITS modify `MESSAGE` longtext character set utf8 collate utf8_general_ci;
alter table REVISIONS modify `MESSAGE` longtext character set utf8 collate utf8_general_ci;
