 com.zzxt.spring.mvc.restful.service包下的

StuService.java接口

package com.zzxt.spring.mvc.restful.service;

import java.util.List;

	public List getStuInfo();
	public Student updateStuInfo(String stuNo);
	public void delStuInfo(String stuNo);
	public void doUpdateStuInfo(Student stu,String stuNo);
}

StuServiceImpl.java上面接口的实现

package com.zzxt.spring.mvc.restful.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.zzxt.spring.mvc.restful.dao.StuInfoDao;

@Service
public class StuServiceImpl implements StuService{
	/*
	 * 
	 * servic层我认为起到了信息转换的作用
	 * 
	 * */
	
	@Autowired
	private StuInfoDao stuInfoDao;
	//添加学生信息
	public void addStuInfo(Student ci) {
		// TODO Auto-generated method stub
		stuInfoDao.insertStuInfo(ci);
		
	}
	//查询所有学生信息
	public List getStuInfo() {
		return stuInfoDao.getStuInfo();
	}
	
	//修改学生信息初始化页面
	public Student updateStuInfo(String stuNo) {

	}	
	//删除学生信息
	public void delStuInfo(String stuNo) {

	}
	//修改学生信息
	public void doUpdateStuInfo(Student stu,String stuNo) {
		// TODO Auto-generated method stub
		stuInfoDao.updateInfo(stu,stuNo);
		
	}
}

com.zzxt.spring.mvc.restful.entity包下

Student.java

package com.zzxt.spring.mvc.restful.entity;

import org.springframework.stereotype.Component;

@Component
public class Student {
	private String stuNo;

	}

	public void setAge(int age) {

}

 com.zzxt.spring.mvc.restful.action包下

stuController.java

package com.zzxt.spring.mvc.restful.action;

	//显示学生信息

		map.put("student", stuServices.getStuInfo());

	}	
	
	
	//增加学生信息
	@RequestMapping(value="/manager",method=RequestMethod.POST)
	public String addStuInfo(Student ci) {		
		//System.out.println("我运行到了页面转接处");
		stuServices.addStuInfo(ci);
		return "redirect:list";			
	}
	
	
	//更新页面初始化；    这段代码要熟记。
	@RequestMapping(value="/updateInit/{stuNo}",method=RequestMethod.GET)
	public String updateInit(@PathVariable("stuNo") String stuNo,Map map) {

	// 更新后跳转

	//删除学生信息

以下是我eclipse下的文件分布， 哈哈，

比较乱

 

web.xml文件

  Archetype Created Web Application
  
  
  
  	contextConfigLocation
  	classpath:applicationContext.xml
  
  
  
  
  	org.springframework.web.context.ContextLoaderListener
