Always use the MVC framework. 2. apply automatic unit testing and test management at each layer. 3. develop according to the specifications, rather than the application server. 4. Plan to use J

Java Application Performance optimization is a commonplace topic, the author based on personal experience, the Java performance optimization is divided into 4 levels: Application layer, database layer, framework layer, JVM layer. Through the introduction of Java performance diagnostic tools and ideas, to give the Sogou business Platform Performance optimization c

the parent delegation model, where a classloader receives a request for class loading, is first delegated to the parent ClassLoader to complete, all load requests are routed to the top-level startup ClassLoader, and if the parent ClassLoader feedback fails to complete the load request, it continues to be loaded by the subclass.The benefit of this load is that the Java class has a hierarchical relationship with precedence over its classloader, avoidin

Introduction: Traditional Java EE applications typically use some kind of MVC framework (for example, Struts) as a front-end user interface, with the advent of Flex, RIA-based clients can bring users cooler interfaces, shorter response times, and closer to the experience of desktop applications. This article will describe how to integrate Flex into an existing Java EE application, and how to apply best

PHP core technology and best practices PHP uses PHPRPC protocol to call JAVA class SOAP (Simple Object Access Protocol, Simple Object Access Protocol) with the continuous competition and design of manufacturers, and because the transfer of objects cannot achieve interoperability, SOAP gradually changes to the transfer of strings, and is finally designed as the XML-based WebService. PHPRPC protocol: it

Java Web concurrency: for update practices, monitoring and solving ., Javawebupdate Writer: BYSocket) Weibo: BYSocket Douban: BYSocket I. Preface We have been talking about concurrency. At present, there are two common practices: Lock Mechanism: 1. pessimistic lock; 2. Optimistic lock. However, this article is mainly used to record my processing experience. In ad

form of synchronization that contains only the visibility, the volatile keyword, and in some cases we only need to focus on the visibility of the code, rather than the mutex, when using synchronizedIt does not seem necessary that we should consider using volatile, a volatile tagged property, when the thread accesses him without reading the cached variable's data, but instead reads it from main memory. It is also worth noting that the use of volatileWhen modifying a double and a long type, you s
