刚学spring mvc，就出现了许多错误；

1.测试类：StudentController，位于包：com.spring；

package com.spring;

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

@Controller
public class StudentController {

	@RequestMapping("/list")
	public String list() {
		System.out.println("list() method");
		return "";
	}
}
