if (typeof metadata.cacheKey === 'function') {

由于直接修改了 metadata.cacheKey, 所以导致 cacheKey 只能生效一次,

建议修改为

                    let cacheKey = metadata.cacheKey; // 添加局部变量
                    const cachingInstance = this.cacheService.get(metadata.cacheInstanceName);
                    if (typeof cacheKey === 'function') {
                        cacheKey = await cacheKey({
                            methodArgs: joinPoint.args,
                            ctx: joinPoint.target[core_1.REQUEST_OBJ_CTX_KEY],
                            target: joinPoint.target,
                        });
                        // metadata.cacheKey = await metadata.cacheKey({
                        //     methodArgs: joinPoint.args,
                        //     ctx: joinPoint.target[core_1.REQUEST_OBJ_CTX_KEY],
                        //     target: joinPoint.target,
                        // });
                    }
                    if (typeof cacheKey === 'string') {
                        return cachingInstance.methodWrap(cacheKey, joinPoint.proceed, joinPoint.args, metadata.ttl);
                        // return cachingInstance.methodWrap(metadata.cacheKey, joinPoint.proceed, joinPoint.args, metadata.ttl);
                    }
                    else {
                        return joinPoint.proceed(...joinPoint.args);
                    }
