Error message

请确保微信视频号配置 appId 的唯一性

What it means

Thrown by the Spring Boot multi-account Channel (视频号) starter when two tenant entries resolve to the same appId, to prevent Redis-based token/ticket cache key collisions (see WxChannelRedisConfigImpl#setAppid). It is a RuntimeException that aborts bean creation at startup.

Solutions

1. List all `wx.channel.apps.*.appId` values and deduplicate.
2. Make each tenant's appId unique; remove blanks.
3. Restart; the check only passes when no grouping key has count > 1.

Example fix

# before
wx.channel.apps:
  tenant-a: { appId: wxch001 }
  tenant-b: { appId: wxch001 }
# after
wx.channel.apps:
  tenant-a: { appId: wxch001 }
  tenant-b: { appId: wxch002 }

// Spring Boot Channel multi: pre-flight appId uniqueness
Set<String> seen = new HashSet<>();
for (WxChannelSingleProperties p : appsMap.values()) {
    if (p.getAppId() == null || !seen.add(p.getAppId())) {
        throw new IllegalStateException("Duplicate/null channel appId");
    }
}

When it happens

Trigger: Two entries under `wx.channel.apps` (or `wxjava.channel.apps`) with the same `appId`; two entries with null appId (both collapse to grouping key `0`).

Common situations: Duplicated tenant YAML blocks; one appId shared by mistake; migrating from single- to multi-account and leaving the same appId on two keys.
