More and more modern large-scale web applications are applied in multithreading and multi-core processor model system.Up to now Java language mechanism has already improved a lot for parallel and concurrency. From architecture view, the design patterns for java should be updated as well. From this article, it will introduce several typical design patters which improve performance and are applied for module development and refactor. At the same time that JDK is improved for design patter would be expected in future.%现代大型系统中多核多线程下的应用越来越多，java语言发展至今对于并行机制有了很大改善，架构中的设计模式从性能的角度也在发生着变化，文章着重介绍几个典型设计模式进行探讨，以便在系统重构或开发中得到性能改进。以及JDK在设计模式上改进的期待。
