接口有多个参数，怎么拼接key呢？

@Cached(name = "test", key = "#request.userId", expire = 6, timeUnit = TimeUnit.HOURS)
@CacheRefresh(refresh = 1, stopRefreshAfterLastAccess = 2, timeUnit = TimeUnit.HOURS)
@CachePenetrationProtect(timeout = 1)
public void test (Reques request);

如果 request里面有id ,name,age 缓存key怎么添加呢？

Start by reading the JetCache annotations shown in the example, especially @Cached and its key expression. Determine whether combining request.userId, id, name, and age is already supported or requires a defined API change; done means the expected multi-field key behavior and usage are documented or implemented, with any relevant validation covered.
