spring管理的ehcache缓存没有起做用的原因

Dao代码如下：

@Repository @EnableCaching class UserDao(jdbcTemplate: JdbcTemplate) {

@Cacheable(keyGenerator = "cacheKeyGenerator", cacheNames = Array("merInfo")) private def findByName(name: String): Option[User] = {

			val sql = ""        //此处为sql
				val rs = jdbcTemplate.queryForRowSet(sql, name)
				if (rs.next()) {
					Some(User(
						rs.getString("name"),
						rs.getString("age")
					))
				} else None
			}


	def findUser(name: String):     Option[User] =  {
		findByName(name)
	}

}

未完，周末再写
