1장 ioc 정리

1. 빈 팩토리 등록 방법

오브젝트를 생성하고 초기화해준다 => @bean
@configuration으로 등록한

/**
 * 팩토리 클래스 UserDao을 생성 책임을 맡았다.
 */
@Configuration // p 96 빈 팩토리를 위한 오브젝트 설정을 담당하는 클래스라고 인식.
public class DaoFactory {
    @Bean
    public DataSource dataSource() {
        SimpleDriverDataSource dataSource = new SimpleDriverDataSource();

        dataSource.setDriverClass(com.mysql.jdbc.Driver.class);
        dataSource.setUrl(DbConstant.JDBC_URL.getStr());
        dataSource.setUsername(DbConstant.ID.getStr());
        dataSource.setPassword(DbConstant.PASSWORD.getStr());

        return dataSource;
    }

    @Bean
    public UserDao userDao() {
        UserDao userDao = new UserDao();
        userDao.setDataSource(dataSource());
        return userDao;
    }
}

2. xml 설정방법

   <bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost/springbook?characterEncoding=UTF-8"/>
        <property name="username" value="root"/>
        <property name="password" value="qkrtmdcks1!"/>
    </bean>
    <bean id="userDao" class="springbook.user.dao.UserDao">
        <property name="dataSource" ref="dataSource"/>
    </bean>

 

GenericXmlApplicationContext context =
new GenericXmlApplicationContext("xml/applicationContext.xml");

UserDao dao = context.getBean("userDao", UserDao.class);
User user = new User("dmdrk1414", "박승찬", "1234");
