[프로젝트명]우클릭 - [Properties] - [Project Facets]

  - java 1.8로 변경 

 

 

Step4 : src/main/webapp/WEB-INF/spring/appServlet/servlet-context.mxl 설정 

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

	<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
	
	<!-- Enables the Spring MVC @Controller programming model -->
	<annotation-driven />

<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
	<resources mapping="/resources/**" location="/resources/" />
	
	<!-- 추가 -->
	<beans:bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
		<beans:property name="driverClassName" value="com.mysql.jdbc.Driver"/>
		 <beans:property name="url" value="jdbc:mysql://localhost:3306/kwanghyup?characterEncoding=UTF-8&amp;serverTimezone=UTC"/>
		 <beans:property name="username" value="root"/>
		 <beans:property name="password" value="1234"/>	
	</beans:bean>
	
	<!-- 추가  -->
	<beans:bean id="sqlSession"
		class="org.mybatis.spring.SqlSessionTemplate">
		<beans:constructor-arg ref="sqlSessionFactory" />
	</beans:bean>
	
	<!-- 추가  -->
	<beans:bean id="sqlSessionFactory"
		class="org.mybatis.spring.SqlSessionFactoryBean">
		<beans:property name="dataSource" ref="dataSource" />
		<beans:property name="mapperLocations" value="classpath*:mappers/*Mapper.xml" />
	</beans:bean>
	
	<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
	<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<beans:property name="prefix" value="/WEB-INF/views/" />
		<beans:property name="suffix" value=".jsp" />
	</beans:bean>
	
	<context:component-scan base-package="com.kb.mybatis" />
	
</beans:beans>

 

Step5 : Mapper.xml 생성 및 설정 

src/main/resources 아래 mappers 폴더 생성

src/main/resources/mappers 아래 Mapper.xml 파일 생성 

 

Mapper.xml 설정 

<?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="test">
  <insert id="testinsert">
  	insert into test (id,pw) 
  	values ('aaa','bbb') 
  </insert>
</mapper>

 

Step6 : HomeController.java 수정 

package com.kb.mybatis;

import org.apache.ibatis.session.SqlSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class HomeController {
		
	@Autowired
	SqlSession sqlSession; 
	
	@RequestMapping(value = "/", method = RequestMethod.GET)
	public String home(Model model) {
		sqlSession.insert("test.testinsert"); 
		return "home";
	}
}

 

출력화면 : home.jsp    

 

DB에 입력한 데이터가 들어갔는지 확인한다.
