···2 项目初始IOC容器
```xml
<?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
https://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- more bean definitions go here -->
</beans>
···3 项目需要自动装配
```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
https://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<context:annotation-config/>
<bean id="dog" class="com.yang.pojo.Dog"></bean>
<bean id="cat" class="com.yang.pojo.Cat"></bean>
<bean id = "people" class="com.yang.pojo.People">
<property name="cat" ref="cat"/>
<property name="dog" ref="dog"/>
<property name="name" value="张3"/>
</bean>
</beans>增加的点：
1 xmlns:context="http://www.springframework.org/schema/context"等等头文件
2 context:annotation-config/
4 项目需要注解
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans
https://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
https://www.springframework.org/schema/aop/spring-aop.xsd">
<!-- 指定要扫描的包，包下面的注解才能够生效-->
<context:component-scan base-package="com.yang.pojo"/>
<!-- 注解驱动-->
<context:annotation-config/>
</beans>增加的点：
<context:component-scan base-package=“com.yang.pojo”/>https://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
