I have encountered these problems during development. If you have different opinions, please note that you can exchange and learn. 1. When writing struts2, in return, remember that success and so on are defined in action. It is a constant. If it is written as the string literal value "success. If you have written a string literal value, you must go to Note: This is case sensitive. 2. In web. XML, the standard filter statement in the latest version (Struts-2.2.3.1 as of now) is as follows: (the

1. Task is a stack that contains a series of activity, followed by the advanced post-out principle.2. Task default behavior:(1) Premise: Activity A and Activity B are in the same application.Action: Activity A starts the secluded task stack (stack state: A), starts activity B (stack State: AB) in activity A, and presses the back return key (stack state: a).(2) Premise: Activity A and Activity B in the same

platform, the Android Framework SDK provides the MEDIACODEC encoder on different chip platforms, the difference is very large, different manufacturers use different chips, while the different chip platforms on Android MEDIACODEC performance slightly The cost of achieving full platform compatibility is often not low.The other is the Android mediacodec hard-coded level of the encoding quality parameters are fixed baseline, so the quality is usually also general. Therefore, under the Android platf

this test toolDuring the creation of a connection between the test script and the Appium server, the original test application is re-signed, a seledroid_xxx.apk is generated, and the APK is installed into the testOn the test device, with this apk to operate the APK, then the server and Seledroid communication is based on an HTTP interface service, this port is 80803. Mixed application WebView part with ChromedriverThe premise is that WebView debug mo

processing is based on two prerequisites. The first premise is to support concurrency, which is, of course, the basic premise. Concurrency here does not have to be parallel, that is, to allow the logical asynchronous, implementation on the serial, the second premise is to support callbacks (callback), because the concurrent, asynchronous processing does not bloc

　　　　In all of the Web site SEO skills, for the page title optimization, the webmaster is easier to control and operate. If we compare a Web site to a book, the theme of the site is the title of the book, and the title of the page is the title of each chapter in the book. The text of the book is always tightly centered around the center of the headline. This can be linked to the content of the page page, it should be around the page title to carry out. For search engines, the first

Method:Overloading and rewritingOverloading: The same argument list with a different method name note: Overloading of methods is independent of the return value of a methodThe > constructor can be overloadedRewrite: (premise: On the basis of inheritance, subclasses can "refactor" a method with the same name in the parent class after acquiring the structure of the parent class)Method override: Format: Modifier return value type method name (parameter

precondition of polymorphism, which makes the relationship between class and class.Iv. polymorphic1. Polymorphism Overview: Polymorphism refers to allowing objects of different classes to respond to the same message. That is, the same message can be used in a variety of different ways depending on the sending object (sending a message refers to a method call).2. Multi-State premise(1) must have an inheritance relationship;(2) There must be a method o

If you are sure to follow the tutorial step by step configuration ADSL No line by the Internet, and secure ADSL no line from the Internet to save the restart equipment, ADSL lights are often bright, but still not dial up, then this article may be helpful to you. Do not panic, or arbitrarily suspected equipment hardware problems, in fact, to do a few simple tests, 95% of the problem can be solved. This article is based on six months to the technical support of various problems, summed up how to

tree. A binary search tree Ideally, the time complexity of the search and other element operations is O (LOGN). However, this is based on the premise that the binary search tree itself constructs the tree is balanced. If we put an element in the normal way by inserting a binary tree, we will lose balance in some extreme cases. For example, by inserting a group of elements that are ascending or descending in order, the final structure is equivalent to

look at this. When this value is set to 0 o'clock, a table with a self-increasing field inserts the behavior of a row of data: 1) Apply for Auto_inc lock 2) Get the current AUTO_INCREMNT value N, give auto_increment plus 1 3) Perform the insert operation and fill n into the new row corresponding field 4) Release Auto_inc lock We see this process, although innodb in order to reduce the size of the lock, the execution of the statement is released immediately, but the lock is still too large-
