Struts1 is a singleton service, request data binding in the Actionform, form as a parameter into the calling method, without the instance variable will not have concurrency problems.Spring MVC's Contrller is also the same patternStruts2 is every time a new instance is created, its request variable is bound to the action's instance variable, and spring manages the S2 action, because spring's bean defaults to creating only one instance, so the scope must be set to prototype.Analysis of Springmvc,

days, you can add a new site, continue to follow the previous operation, found that the Web page is not open, or continue to open the inter-domain policy, you can access. It seems to be the destination address of the inter-domain policy. Here is a key point, and now a lot of sites are no longer purely their own production of all the content, will be called from other places, so you open a Web page, actually this page will tell you from which IP to download something. Understand the above situat

The physical separation between the data layer and the business layer is done, and Windows is made a database server and Linux as a Web server;3. An error occurred: encoding UTF8 of the non-mapped characters, because the Java program is stored in the Chinese characters, so compiled pass, the method can be "javac-e

When we write a single py test file when run directly on OK, but when we have a lot of a lot of such py, does it have to be one click to run it, of course not.

　 Test case writing is not easy, write a professional test case, is the content that all testers consider, in fact the writing of use cases can be done by some ideas, many mature companies in order to enhance the professional use case, there will be their own use case library, including processes, concerns, as well as their own definition of templates. Today as a Test veteran of me after years of experience precipitation summed up a set of test case w

cases. Such a code would be difficult to understand. Specifically create an object to hold such orphan attributes, and move only the behavior associated with him to that class. The most common is that a particular algorithm requires certain variables that only the algorithm is useful for. 　Message Chain A message chain occurs when a client requests another object to an object, and then the customer asks another object to the other object, and then re
