스프링 어노테이션을 사용하기 위한 xml설정

자동으로 어노테이션방식으로 하는법

<!-- 컴포넌트 자동 탐생 등록 -->
<context:component-scan base-package="kr.co.jhta.web.*"></context:component-scan>
<!-- mvc 컴포넌트 활성화 -->
<mvc:annotation-driven></mvc:annotation-driven>

<!-- view resolver -->
<mvc:view-resolvers>
	<mvc:jsp prefix="/views/" suffix=".jsp"/>
</mvc:view-resolvers>

<!-- 기본 서블릿 핸들러 -->
<mvc:default-servlet-handler/>

<!-- myBaits : dataSource -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
	<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
	<property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"/>
	<property name="username" value="scott"/>
	<property name="password" value="tiger"/>
</bean>

<bean id="factory" class="org.mybatis.spring.SqlSessionFactoryBean">
	<property name="dataSource" ref="dataSource"></property>
	<property name="configLocation" value="/WEB-INF/sqlMapConfig.xml"/>
	<property name="mapperLocations" value="/WEB-INF/boardMapper.xml"/>
</bean>

<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
	<constructor-arg ref="factory"></constructor-arg>
</bean>

</beans>

<mvc:annotation-driven></mvc:annotation-driven>방식과

<context:annotation-config></context:annotation-config> 방식 2가지가 있는데

mvc방식을 사용하면 된다 내부적으로 context방식을 포함하고 있다

 

수동으로 구현하는 방법

 

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

<!-- 스프링 컨테이너에게 위임할 빈을 등록 : app.xml -->
<!-- Handler Mapping -->
<bean id="beanNameUrlHandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>

<!-- 등록할 컨트롤러 -->
<bean id="/hello.do" class="spring_web01.HelloController"></bean>
<bean id="/welcom.do" class="spring_web01.WelcomController"></bean>

<!-- view Resolver -->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/"></property>
	<property name="suffix" value=".jsp"></property>
</bean>
</beans>

컨트롤러를 구현하는 방식으로 처리

package spring_web01;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

// Controller : 비지니스 로직이 담겨있는 클래스
// Controller 인터페이스를 구현한 클래스
public class HelloController implements Controller{

	@Override
	public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
		//전달할 데이터 : req.setAttribute()
		
		//전달할 데이터 : Model
		//찾아갈 뷰 객체 : View
		ModelAndView mav = new ModelAndView();
		//req.setAttribute("data","안녕하세요");
		mav.addObject("data","안녕하세요");
		mav.setViewName("hello");
		
		return mav;
	}

}

 

프로퍼티를 따로 두고 커넥션풀도 설정할때 방식

<!-- db 설정파일을 읽는 객체 -->
<bean id="property" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
	<property name="location" value="/WEB-INF/db.properties"/>
</bean>

<!-- dbcp : DataBase Connection Pooling -->

<bean id="dataSource" class="org.apache.tomcat.dbcp.dbcp2.BasicDataSource">
	<property name="driverClassName" value="${driver}"></property>
	<property name="url" value="${url}"></property>
	<property name="username" value="${username}"></property>
	<property name="password" value="${password}"></property>
</bean>

<!-- 공장 객체 -->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
	<property name="dataSource" ref="dataSource"></property>
	<property name="configLocation" value="/WEB-INF/sqlMapConfig.xml"></property>
</bean>

 

 

이름 : db.properties

driver=oracle.jdbc.driver.OracleDriver
url=jdbc:oracle:thin:@localhost:1521:orcl
username=scott
password=tiger

 

 

이름 : sqlMapConfig.xml
