that the existence of Jsp,servlet can help users solve most problems, but because of their coding on the development of the project has brought a lot of inconvenience, reusability is also poor, So struts came into being to help users solve these problems in the shortest possible time. The Struts framework provides the following services:(1) as a servlet for the

Everything has certain routines and rules, and Struts 2 + hibernate 3 + spring is also the same. struts2 is much better than struts1, but currently the only thing that is uncomfortable Struts2 does not have any good ide tools to support design, such as dw8, and hopes to improve it in the future. Here, we use a simple user registration and login to describe the simple combination between the three. The other

configure a struts application in three steps. 1. register the tag library in the deployment descriptor (Web. xml file): The above code tells the servlet container about the struts HTML Tag library and where to find the TLD file of the tag library. 2. Be sure to copy the struts-html.tld file to the WEB-INF directory.

illustrate this process. In this example, an interceptor is implemented, and the function of the interceptor is to map the Key-value in a property file to the value of the corresponding property. As the following is the contents of a property file: name = 超人 price = 10000 We can define the name and price attributes in the action class, and when this interceptor is referenced in the action, the property is automatically assigned a value. The following rules are used for using the Interceptor:

One of the most common applications for JSP/servlet development is to display a list of entries (such as the user list,ArticleList, item list, and so on), and then the user selects to operate a certain entry based on browsing. Now let's talk about how to use struts to implement this function. In general, applications developed with Struts should not directly access the. jsp file, but forward requests by a

Struts 1.x principlesStruts When I got started with this framework, I was wondering why it was struts, not CraigFramework. Structure and support. Why does struts work? In the struts in action book, struts developers also tal

first, the concept The application may have many action declarations that simplify multiple similar mapping relationships into a mechanism for mapping relationships (multiple action classes----an action tag)Wildcard mapping Rules: Typically, "*" matches 0 or more characters, and the substring of the URI string to which the wildcard is matched can be referenced by {1}, {2}. {1} matches the first substring,

Document directory Common configurations: Struts is an open-source framework developed by the Jakarta project team of Apache and an implementation of the MVC design pattern. Struts2.x is based on webwork, so struts1.x and struts2.x are very different. 1. Relationship between struts and traditional MVC Ii. Struts

Action Action is the basic component in struts. After learning the struts execution process, the processing is eventually transferred to an action class. We obtain form data in the action, perform business logic processing, and forward and transmit pages. 1. Configuration File Ii.
