SpringMVC_@Scope注解与RequestParam注解

package cn.java.controller.front;

import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import cn.java.entity.User;

@Controller
@Scope("prototype") //设置为多例，Scope只能修饰类，如果设置为单例，只能等张三用完，李四才能用，多例的话张三创建一个，李四创建一个，互不干扰
public class HomeController {
    @RequestMapping(value="test1.htm")
    public String test1(User user) {
        System.out.println(user);
        return "success.jsp";
    }
}

    @RequestMapping(value="test1.htm")
    public String test1(@RequestParam(name="username",defaultValue="james",required=true) String un,@RequestParam(name="password")String pwd,@RequestParam(name="age")Integer a) {
        System.out.println("username="+un);
        System.out.println("password="+pwd);
        System.out.println("age="+a);
        return "success.jsp";
    }
