1、HelloController.java
通过model.addAttribute(key,value)进行传值
package zttc.itat.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloController{
//RequestMapping表示用哪个URL来对应
@RequestMapping{{"/hello","/"}}
public String hello(String username, Model model){
System.out.println("hello");
model.addAttribute("username", username);
model.addAttribute(username);//默认使用对象的类型作为key,即model.addAttribute("string",username)，注意string开头是小写
System.out.println(username);
return "hello";
}
@RequestMapping{{"/welcome"}}
public String welcome(){
System.out.println("welcome");
return "welcome";
}
}
