spring注入IOC

注入复杂的类属性

	private String name;
	private int age;
	private List course;
	private Map<String,String> map;

beans.xml配置

	<bean id="student" class="com.model.Student">
		<property name="name" value="liuhao"></property>
		<property name="age" value="18"></property>
		
		<!-- <property name="object" ref="属性类的bean的id"></property> -->
		
		<property name="course" >
			<list>
			<value>100</value>
			<value>99</value>
			<value>66</value>
			</list>
		</property>
		
		<property name="map">
			<map>
				<entry>
					<key><value>home</value></key>
					<value>henan</value>
				</entry>
				<entry>
					<key><value>aihao</value></key>
					<value>nv</value>
				</entry>
			</map>
		</property>
	</bean>

加载beans配置的类

ApplicationContext path = new ClassPathXmlApplicationContext("beans.xml");
Student student = path.getBean("student", Student.class);//(bean的id,Student.class)
System.out.println(student);

自动装配方式

<bean id="dog" class="com.hdu.autowire.Dog"></bean>
<bean id="cat" class="com.hdu.autowire.Cat"></bean>

<bean id="user" class="com.hdu.autowire.User" autowire="byName" scope="prototype">
	<property name="str" value="liuhao"></property>
</bean>
