[ Spring ] 스프링 설정파일 (XML 파일을 JAVA 파일로 변경하기)

1.  XML 파일을 JAVA 파일로 변경하기 위해, JAVA 파일에서는 메서드를 생성한다.

 1) XML 파일   →  JAVA 파일  ①

< XML >

<bean id="studentDao" class="ems.member.dao.StudentDao" ></bean>

<bean id="registerService" class="ems.member.service.StudentRegisterService">
<constructor-arg ref="studentDao" ></constructor-arg>
</bean>

< JAVA >

@Configuration
public class MemberConfig {

	@Bean
	public StudentDao studentDao() {
		return new StudentDao();
	}

	@Bean
	public StudentRegisterService registerService() {
		return new StudentRegisterService(studentDao());
	}
}

 

 2) XML 파일   →  JAVA 파일  ②

< XML >

<bean id="dataBaseConnectionInfoDev" class="ems.member.DataBaseConnectionInfo">
		<property name="jdbcUrl" value="jdbc:oracle:thin:@localhost:1521:xe" />
		<property name="userId" value="scott" />
		<property name="userPw" value="tiger" />
	</bean>

< JAVA >

	@Bean
	public DataBaseConnectionInfo dataBaseConnectionInfoDev() {
		DataBaseConnectionInfo infoDev = new DataBaseConnectionInfo();
		infoDev.setJdbcUrl("jdbc:oracle:thin:@localhost:1521:xe");
		infoDev.setUserId("scott");
		infoDev.setUserPw("tiger");
		
		return infoDev;
	}

 

 3) XML 파일   →  JAVA 파일 ③

< XML >

<bean id="informationService" class="ems.member.service.EMSInformationService">
		<property name="info">
			<value>Education Management System program was developed in 2015.</value>
		</property>
		<property name="copyRight">
			<value>COPYRIGHT(C) 2015 EMS CO., LTD. ALL RIGHT RESERVED. CONTACT MASTER FOR MORE INFORMATION.</value>
		</property>
		<property name="ver">
			<value>The version is 1.0</value>
		</property>
		<property name="sYear">
			<value>2015</value>
		</property>
		<property name="sMonth">
			<value>1</value>
		</property>
		<property name="sDay">
			<value>1</value>
		</property>
		<property name="eYear" value="2015" />
		<property name="eMonth" value="2" />
		<property name="eDay" value="28" />
		<property name="developers">
			<list>
				<value>Cheney.</value>
				<value>Eloy.</value>
				<value>Jasper.</value>
				<value>Dillon.</value>
				<value>Kian.</value>
			</list>
		</property>
		<property name="administrators">
			<map>
				<entry>
					<key>
						<value>Cheney</value>
					</key>
					<value>cheney@springPjt.org</value>
				</entry>
				<entry>
					<key>
						<value>Jasper</value>
					</key>
					<value>jasper@springPjt.org</value>
				</entry>
			</map>
		</property>
		<property name="dbInfos">
			<map>
				<entry>
					<key>
						<value>dev</value>
					</key>
					<ref bean="dataBaseConnectionInfoDev"/>
				</entry>
				<entry>
					<key>
						<value>real</value>
					</key>
					<ref bean="dataBaseConnectionInfoReal"/>
				</entry>
			</map>
		</property>
	</bean>

< JAVA >

@Bean
	public EMSInformationService informationService() {
		EMSInformationService info = new EMSInformationService();
		info.setInfo("Education Management System program was developed in 2015.");
		info.setCopyRight("COPYRIGHT(C) 2015 EMS CO., LTD. ALL RIGHT RESERVED. CONTACT MASTER FOR MORE INFORMATION.");
		info.setVer("The version is 1.0");
		info.setsYear(2015);
		info.setsMonth(1);
		info.setsDay(1);
		info.seteYear(2015);
		info.seteMonth(2);
		info.seteDay(28);
		
		ArrayList<String> developers = new ArrayList<String>();
		developers.add("Cheney.");
		developers.add("Eloy.");
		developers.add("Jasper.");
		developers.add("Dillon.");
		developers.add("Kian.");
		info.setDevelopers(developers);
		
		Map<String, String> administrators = new HashMap<String, String>();
		administrators.put("Cheney", "cheney@springPjt.org");
		administrators.put("Jasper", "jasper@springPjt.org");
		info.setAdministrators(administrators);
		
		Map<String, DataBaseConnectionInfo> dbInfos = new HashMap<String, DataBaseConnectionInfo>();
		dbInfos.put("dev", dataBaseConnectionInfoDev());
		dbInfos.put("real", dataBaseConnectionInfoReal());
		info.setDbInfos(dbInfos);
		
		return info;
	}

 

2. 스프링 컨테이너 변경

< XML >

GenericXmlApplicationContext ctx = new GenericXmlApplicationContext("classpath:applicationContext.xml");

< JAVA >

AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(MemberConfig.class);
