SpringMVC's HelloWord, springmvchelloword
SpringMVC (helloWord)1. Import jar package 2. Create xml files for spring and springMVC 3. configure the listener and core servlet and location of spring in xml. The following describes in detail each step 1. Create a web project demoapp2, import spring jar 3 under web-INF/lib, and spring xml, you only need to write a helloword, you only need to configure a scan package (spring-config.xml?
