AOP and permission control implementation Banqiao Renren http://www.jdon.com In the past, in the J2EE system, there were two main implementation methods: application implementation and J2EE container implementation. Traditional application implementation This is the most direct and traditional solution. Generally, a permission judgment statement is added before a specific method, as shown below: Public class forumfactoryproxy extends forumfactory {......Public Forum createforum (string

Discountprice (), actually composite uses iterator to traverse the entire tree structure, looking for objects that also contain this method and implementing the call execution.Composite is a clever model of wisdom, and in practice, if you encounter a tree structure, we can try to use this pattern.Take the forum as an example, there are many posts in a version (message), these posts have the original paste, there is a response to the original sticker, is a typical tree structure, then of course

open source program is jive and Petstore. Jive is a very well-known foreign BBS program, completely open source. The forum is designed using a lot of advanced technology, such as cache, user authentication, Filter, XML and so on, and the forum completely blocked access to the database, can easily be ported in different databases. Forum also has a convenient installation and management procedures, which is

Proxy is a more useful mode, and there are many variants, shouldProxy is the meaning of proxy. We may have the concepts of proxy servers. The concept of proxy can be interpreted as: there is an intermediate layer between the starting point and the destination,Proxy.

question I can solve, is not become a master of it? Of course it's not that simple, it's just the first step Long march. Don't believe me? Do you know how to do it, do you know how to design it, do you know how to organize people to develop it? You may have nothing else in mind now, except for some messy code! What you lack right now is the actual work experience, not the programs that come out of the book. So you have to find a Java programming work to do it (if students can go to do part-time

Manager protocol is being developed through the open XEP process. We hope to work with other servers vendors so, the entire Xmpp/jabber community supports the protocol. We also expect there would be the other implementations of the connection managers that'll be compatible with OpenFire. For example, a connection manager written with native code is able to achieve very high scalability on a specific plat Form. Can connection management be used on other servers? Of course (theoretically). The

LOG4J is currently the industry standard for log records, and its powerful, well-developed features can meet most of our needs. Provide the perfect log processing method for our application system. As we know, the log levels in log4j are divided into six levels such as log, DEBUG, INFO, WARN, ERROR, and fatal. Its flexible configuration mechanism is also a major reason why log4j is good enough to use class inheritance to package, class, and root-level configurations. In my study of the process
