接口有多个参数，怎么拼接key呢？

[Apache001]

@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？

[JavayVeneno]

key="#request.userId+'-'+#request.name+'-'+#request.age "
