the perspective of APP app1, we regard integration with external app app3 based on the requirement-response mode as a "synchronous service" activity, the notification is regarded as an "Asynchronous receipt" activity. That is to say, in request-response and notification, our reference point application app1 becomes a service provider (service endpoint) and receives messages from the client. In this article, you will learn how to implement these two modes in such applications (assuming that they

listen to the three main framework, about the three framework, do the following understanding : Three main frames:struts+hibernate+spring Java The three frameworks are mainly used to make WEN application. Struts mainly responsible for the display of the presentation layerSpring take advantage of its IOC and the AOP to handle the control business (responsible for the operation of the database)Hibernate mos

We have made many introductions to the Java EE Framework. This article will give a systematic summary of the four frameworks commonly used in Java EE. Struts Struts is an MVC framework based on the Sun Java EE platform, mainly implemented using Servlet and JSP technologies. The Struts framework can be divided into t

: When growth is needed, vectors grow by default to the original, while ArrayList is half the original.HashMap and Hashtable are mainly from three aspects. I. Historical reasons: Hashtable is based on the old dictionary class, HashMap is an implementation of the map interface introduced by Java 1.2 two. Synchronization: Hashtable is thread-safe, that is, it is synchronous, and HashMap is unsafe for the line program. , not synchronous three. Value: Onl

For some sensitive systems such as payments, transactions need to be reinforced, it is necessary to take into account possible attack situations to prevent, so there is such a simple security framework. In the code of the predecessor (see: http://blog.csdn.net/zhongweijian/article/details/8680737) I greatly refactor to better understand Java Web security implementation measures.Source code: Http://git.oschina.net/sp42/ajaxjs/tree/master/ajaxjs-securit

EE container, and of course it can run independently. 　　 The Jbosscache consists of two modules: Treecache and TREECACHEAOP. 　　 treecache– is a tree-structured transactional cache of replication. 　　 treecacheaop– is an object-oriented cache that uses AOP to dynamically manage Pojo (Plain old Java Objects) 　　 Note: AOP is the continuation of OOP and is the abbreviation for Aspect oriented programming, meaning aspect-oriented programming. 　　 Official w

search is high; but adding or removing elements involves moving a large number of elements, which is inefficient.2) ArrayList provides three different construction methods, the parameterless construction method defaults to generating an array of type object of length 10, and when the number of elements added in the collection is greater than 10, the array is automatically expanded, i.e. a new array is generated and the elements of the original array are placed in the new array.3) Ensurecapacity

. The greatest feature of the vector class is thread safety, which is uncommon throughout the set framework. It is because of thread safety that execution is inefficient and is now almost obsolete. Even though it is not used in multithreaded programming, it is replaced with a ArrayList lock. The inside of the vector is an array structure and is extensible, with a step size of 100%. Vector additions and deletions are very slow.6.2ArrayList class.The ArrayList class is intended to replace the vect

1. Jdk5.0-jdk. JDK5 annotation, generics, variable parameters and autoboxing, it is difficult to give up after. and annotation more and more applications, if Springside still cling to JDK1.4, will be more and more limitations. If the user's application server only supports JDK1.4, you can use the Retrotranslator compatibility scheme. 2. Spring 2-j2ee Framework. The Java EE full-stack Framework for the temporary lack of strong competitors. 3. Hiber

statements. )。 However, it is important to note that the session object is non-thread-safe. At the same time, Hibernate's session differs from the HttpSession in JSP applications. When the term "session" is used, it is actually referring to the session in Hibernate, and later the HttpSession object is called the user session.2. Sessionfactory interface: Responsible for initializing hibernate. It acts as a proxy for the data storage source and is responsible for creating session objects. The fac

Common java testing frameworks1. Common Unit testing frameworks junit4 and TestNG You can use the annotation @ Before @ After @ BeforeClass @ AfterClass to initialize and end methods and classes respectively.TestNG example: public class TestngAnnotation { // test case 1 @Test public void testCase1() { System.out.println("in test case 1"); } // test case 2 @Test public void testCase2() { Sys

need to do some special processing. Set because it is a hash to achieve, so there is no guarantee to add into the set order, this time you can consider using the Linkedhashset class to handle, Linkedhashset class when the Add method is added, When printing can guarantee that the order of printing and the order of the original added is the same, HashSet is not guaranteed. There is also a class is TreeSet, tree set, this in some of the above interface and abstract class to do bedding, there are s

Currently, the declared restful Java frameworks include the following:Restlet (http://www.restlet.org /)Cetia4 (https://cetia4.dev.java.net /)Apache axis2 (http: // http://ws.apache.org/axis2)Sqlrest (http://sqlrest.sourceforge.net /)Rest-art (http://rest-art.sourceforge.net /) The following provides a comprehensive analysis of these frameworks.

Collection of Java Collection frameworks and javacollectionThis figure is a class diagram of the relationship between Collection-related interfaces and classes in java. Among them, the class is only part of the set framework, a more common part. It was really hard to draw a class chart for the first time, but the harvest was not small. The following describes the

Summary: Hibernate's role is to allow entity classes to map with databases, to persist data, to replace JDBC, so that we do not write as many SQL statement code.1. First on the official website www.hibernate.org download Hibernate package, about how to download the online also has a detailed tutorial. After the download, the required inside the jar package is all necessary, can be placed in a library, and then add MySQL (or other database) of the driver package, is all the class library we need.

manipulated, for example:while (It.hasnext ()) {Note that you cannot use List.add ("demo")!!!!!!It.add ("demo");}3.
