Therefore , i had a team test the performance and found to my happy surprise that there is no appreciable difference between the " client " calling a local get attribute method through the local interface and having the entity bean implementation call its own abstract get attribute method - as long as the client and entity are both within a global transaction scope 因此，我让一个团队进行了性能测试，结果我很惊喜地发现，只要客户机和实体均位于同一个全局事务范围内， “客户机”通过本地接口调用本地get < attribute > ( )方法和让实体bean实现调用自身抽象的get < attribute > ( )方法，这两种方式之间并没有明显的区别。
