In the past few years, JSP + servlet was a common technology for web development using Java, but later struts gradually became popular, and then spring became the dominant, while hibernate became the representative of the persistent layer processing technology.

I want to do a login registration function under the SSH framework. Although there are many similar tutorials on the internet, I read a circle, either a version issue or missing many key steps. After several hours of hard work, we finally completed the so-called simple SSH integration to implement the registration function. Next we will share all the steps and hope to help our friends in need. The following uses a simple registration module as an example to describe the integration steps and con

The system of Struts 2 differs greatly from that of Struts 1 because Struts2 uses the design core of WebWork, rather than Struts1. Struts2 uses a large number of interceptors to process user requests, allowing the user's business logic controller to be separated from the Servlet API. The general process of Struts

For most common types, developers do not need to care about type conversion. Struts 2 can complete most common type conversion tasks. These common types are converted using the built-in type converter of Struts 2. Struts 2 has bui
