题干

利用三大框架整合技术，向Student表的插入一条数据，具体要求完成如下操作
1.配置Spring MVC核心配置文件springmvc-config.xml,重点配置注解扫描包和视图解析器
2.参照下图Student表结构，完成数据层的Mapper接口及映射文件的编写
3.编写业务层的StudentService接口及其实现类
4.参照下图前台界面，编写信息录入页面login.jsp，并编写Controller接收请求数据，并进行处理。
5.若插入成功，将插入的信息在success.jsp页面中进行显示。

代码

1、配置Spring MVC核心配置文件springmvc-config.xml

<!-- 头文件 -->
<?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:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        ">
	<!-- 只扫描controller包 -->
	<context:component-scan base-package="com.haust.controller"></context:component-scan>
	<!-- 自定义视图解析器 -->
	<bean id="viemResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
</beans>

2、数据层的Mapper接口及映射文件

//StudentMapper接口
public interface StudentMapper 
		public Student insertStudent(Student student);



<!-- StudentMapper.xml文件 -->
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.haust.mapper.StudentMapper" >
	<insert id="insertStudent" parameterType="com.haust.Student">
	 	insert into student 
		values(#student_id,#sname,#password,#sex,#note)
	 </insert>
</mapper>

3、业务层的StudentService接口及其实现类

//StudentService接口
public interface StudentService 
	public Student insertByStudent(Student student);


//实现类
package com.haust.service.impl;
import javax.annotation.Resource;
import com.haust.mapper.StudentMapper;
import com.haust.pojo.Student;
import com.haust.service.StudentService;
public class StudentServiceImpl implements StudentService
	@Resource
	private StudentMapper  studentMapper;
	public Student insertByStudent(Student student)
		return studentMapper.insertStudent(student);

4、login.jsp，并编写Controller接收请求数据，并进行处理

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Insert title here</title>
</head>
<body>
	<!-- 只用记这部分 -->
	<form action="$pageContext.request.contextPath/doLogin" method="post">
	编号:<input type="text" name="student_id"></br>
	姓名:<input type="text" name="sname"></br>
	密码:<input type="text" name="password"></br>
	备注:<textarea rows="3" cols="" name="note"  ></textarea></br>
	性别:<input type="radio" name="sex" value="1">男
		<input type="radio" name="sex" value="0">女 </br>
	<input type="submit" value="提交">
	<input type="reset" value="重置">	
</form>
</body>
</html>

//StudentController类接收请求数据

@Controller
public class StudentController 
	@Autowired
	StudentService studentService;
	
	@RequestMapping("/login")
	public String tologin()
		return "login";
	
	
	@RequestMapping("/doLogin")
	public String insert(Student student, Model model) 
		studentService.insert(student);
		model.addAttribute("student", student);
		return "success";

5、success.jsp页面

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
$student.student_id
$student.sname

</body>
</html>
