project, so this is also an implicit risk.We can generally conclude that some projects or products that do not work very well are not suitable for use with the IOC framework products. In addition, if the team members of the lack of knowledge, the IOC framework products do not have a deep understanding, do not introduce. Finally, special emphasis is placed on the

version queryMethod One:uname-aMethod Two:cat/proc/versionThe Linux kernel version number consists of the major version number, the minor version number, the revision number, the fine tuning version number, and the special tuning description for the specific Linux system. Linux divides memory and peripherals into three main categories, character devices, block devices, and network devices. The communication between the Linux kernel and the network device is completely different from that of t
Deep understandingJavaVirtual machines:JVMAdvanced Features and best practicesRead notes (Memory principle, exception handling):1. JVM Runtime, Memory partitioning: 2. Program Counter: The JVM considers this count as the number of rows that the current thread executes for a byte code, and selects the action statement to be executed based on the value of the counter. This is a thread-private, non-shareable, and cannot be accurately executed by the curr
Recently, I wanted to learn more about Java threads, and I wanted to know how to implement them, such as thread sharing, thread-private space, and thread-direct synchronization control. If you can understand its implementation, it will be of great help to learn the thread deeply. I'm looking at a piece of information about the deep Java memory model. This is the
Sen Wang's "Deep Adventures in Java" and discuss these two issues in depth.The second step is to learn the Java syntax. Java syntax is Class C + +, basically the mainstream programming language is not Class C, is the class C + +, there is nothing new, so the grammar of learning
eliminates all interfaces required for Object Persistence and enhances the query language of EJB.
What are the disadvantages of entity EJB?
Learning and using the EJB architecture is not simple. You should prepare to learn some terms, suchRemote Interface),Home interface (home interface),Activation),Passivation (passivation)And so on. Most of them are only applicable to the EJB world.
The EJB architecture does not provide persistence independence.

The mention of Java internal class (Inner Class) may be unfamiliar to many people, in fact, similar concepts in C + +, that is, nested class (Nested Class), about the difference between the two and the connection, in the following will be compared. The inner class looks at the surface, is to define a class in the class (see below, the inner class can be defined in many places), but it is not so simple, at first glance the inner class seems superfluous
Now many beginners and programmers are flocking to learn the book-level framework of Web development: STRUTS2,Spring,hibernate. It seems that these frameworks become a person who is proficient in Java and whether it will write the only factual criteria for the EE program and the necessary foundation for job hunting.However, if you ask these programmers during an interview, why do you study these frameworks?

the Linux kernel. I think there must be someone who wants to ask if aio sounds bigger than nio, why not use AIO? AIO actually has applications, but one problem is that Linux does not support AIO, so the AIO-based program runs on Linux less efficiently than NIO. While Linux is the most important server OS, NIO is now more widely used than AIO.Speaking of which, you may already understand that Epoll must have a deep cause with NIO. Yes, if you look clo
Note, I believe everyone will know, like @requestmapping, @Resource, @Controller and so on some of the annotations, we have used, then, his tool class you used it? Let's share the annotation tool class with you.The role of annotations:1. Generate the document. This is the most common, and also the earliest annotations that Java provides. Commonly used @see @param @return, etc.2, tracking code dependencies, to implement the alternative configuration fi
