Spring 依赖注入配置

Spring把daobean注入到servicebean

生成DaoBean

public class TestDaoBean implements DuncanDao {
	/* (non-Javadoc)
	 * @see dun.dao.bean.updatebean#updatebean()
	 */
	public void updatebean() {
		System.out.println("DuncanDaoBean update");
	}
	
}

生成ServiceBean

public class TestServiceBean implements TestService {
	/* (non-Javadoc)
	 * @see dun.service.bean.DuncanService#save()
	 */
	public void save(){
		testDao.updatebean();
		System.out.println(name);
		System.out.println("duncan service bean save");
	};
	
	private TestDao testDao;

	public TestDao getTestDao() {
		return testDao;
	}

	public void setTestDao(TestDao testDao) {
		this.testDao = testDao;
	}
	private String name;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

beans.xml生成

<bean id="testDao" class="test.dao.bean.TestDaoBean"></bean>
	<bean id="testService" class="test.service.bean.TestServiceBean">
		<property name="testDao"  ref="testDao"></property>
		<property name="name"  value="I love you"></property>
	</bean>
	<bean id="testService1" class="test.service.bean.TestServiceBean">
		<property name="testDao">
			<bean id="testDao1" class="test.dao.bean.TestDaoBean"></bean>
		</property>
		<property name="name"  value="I hate you"></property>
	</bean>

测试文件

	@Test public void instanceSpring(){
		ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
		TestService duncanService = (TestService)ctx.getBean("testService1");
		duncanService.save();
	}
