註解開發SPringMVC

1.導入jar包和配置web.xml文件（配置文件詳情內容見SPringMVC的web.xml配置）

2.配置在classpath目錄下的SPringMVC.xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 
		http://www.springframework.org/schema/mvc 
		http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd 
		http://www.springframework.org/schema/context 
		http://www.springframework.org/schema/context/spring-context-3.2.xsd 
		http://www.springframework.org/schema/aop 
		http://www.springframework.org/schema/aop/spring-aop-3.2.xsd 
		http://www.springframework.org/schema/tx 
		http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

		<!-- 掃描註解 -->
		<context:component-scan base-package="com.mingde"></context:component-scan>
		<!-- 配置映射器 -->
		<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>
		<!-- 配置適配器 -->
		<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"></bean>
		
		<!-- 配置響應跳轉 -->
		<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			<property name="prefix" value="/WEB-INF/student/"></property>
			<property name="suffix" value=".jsp"></property>
		</bean>
		
</beans>

3.配置controller（控制層）的StudentController.java文件（名字隨便取）

package com.mingde.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.mingde.dao.StudentDao;
import com.mingde.po.Student;

@Controller
@RequestMapping("stu")		//在驅動服務器後，在地址欄加上/stu，然後根據下方要調用那個方法就再加上方法上面的註解裏的路徑+action，如stu/list.action,即可調用該方法
public class StudentController  {
	@Resource(name="sd")
	private StudentDao sd;
	
	@RequestMapping("/list")
	public ModelAndView seeAll()throws Exception{
		List seeAll = sd.SeeAll();
		ModelAndView mv=new ModelAndView("list", "students", seeAll); //參數一：要跳轉的頁面，參數二和三是要傳到頁面上的數據，參數二爲數據名，參數三爲數據
		return mv;
	}
	
	@RequestMapping("/toAdd")
	public String toAdd(Model model) throws Exception{
		List seeClasses = sd.SeeClasses();
		model.addAttribute("cls", seeClasses);
		return "toAdd"; 	//要跳轉的頁面
	}
	
	@RequestMapping("/add")
	public String add(Student st)throws Exception{
		sd.add(st);
		return "redirect:list.action"; 	//重定向
	}
	
	@RequestMapping("toUpdate")
	public ModelAndView update(int sid)throws Exception{
		Student find = sd.find(sid);
		List seeClasses = sd.SeeClasses();
		ModelAndView mv = new ModelAndView("update"); //要跳轉的頁面
		mv.addObject("cls",seeClasses);
		mv.addObject("st", find);
		return mv;
	}
	
	@RequestMapping("update")
	public String update(Student st)throws Exception{
		sd.update(st);
		return "redirect:list.action";  //重定向
	}
	
	@RequestMapping("delete")
	public String delete(int sid) throws Exception{
		sd.delete(sid);
		return "redirect:list.action";	//重定向
	}
	
}

在驅動服務器後，在地址欄加上/stu，然後根據下方要調用那個方法就再加上方法上面的註解裏的路徑+action，如stu/list.action,即可調用該方法

Dao層

package com.mingde.dao.impl;

import java.util.List;

import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.handlers.BeanHandler;
import org.apache.commons.dbutils.handlers.BeanListHandler;
import org.springframework.stereotype.Repository;

import com.mingde.dao.StudentDao;
import com.mingde.po.Classes;
import com.mingde.po.Student;
import com.mingde.utils.JdbcUtils;

@Repository("sd")
public class StudentDaoImpl implements StudentDao {

	QueryRunner qr;
	public StudentDaoImpl() {
		qr=new QueryRunner(JdbcUtils.getDataSource());
	}
	
	@Override
	public List SeeAll() throws Exception {
		return qr.query("select * from student", new BeanListHandler<>(Student.class));
	}

	@Override
	public List SeeClasses() throws Exception {
		return qr.query("select * from classes", new BeanListHandler<>(Classes.class));
	}

	@Override
	public void add(Student st) throws Exception {
		qr.update("insert into student values(seqstudent.nextval,?,?,?,?,to_date(?,'yyyy-MM-dd'),?)",st.getSname(),
				st.getSex(),st.getAge(),st.getAddr(),st.getBirth(),st.getCid());
	}

	@Override
	public Student find(int sid) throws Exception {
		return qr.query("select * from student where sid=?", new BeanHandler<>(Student.class),sid);
	}

	@Override
	public void update(Student st) throws Exception {
		qr.update("update student set sname=?,sex=?,age=?,addr=?,birth=to_date(?,'yyyy-MM-dd'),cid=? where sid=?",
				st.getSname(),st.getSex(),st.getAge(),st.getAddr(),st.getBirth(),st.getCid(),st.getSid());
	}

	@Override
	public void delete(int sid) throws Exception {
		qr.update("delete from student where sid=?",sid);
	}

}
