|
## 说明
|
|||
|
|
|
|||
|
|
1. 使用spring版本5.3.5
|
|||
|
|
2. 起始类ClassPathXmlApplicationContext，可以使用org.springframework.context.support.GenericApplicationContext自定义读取配置
|
|||
|
|
|
|||
|
|
```java
|
|||
|
|
GenericApplicationContext ctx = new GenericApplicationContext();
|
|||
|
|
XmlBeanDefinitionReader xmlReader = new XmlBeanDefinitionReader(ctx);
|
|||
|
|
xmlReader.loadBeanDefinitions(new ClassPathResource("applicationContext.xml"));
|
|||
|
|
PropertiesBeanDefinitionReader propReader = new PropertiesBeanDefinitionReader(ctx);
|
|||
|
|
propReader.loadBeanDefinitions(new ClassPathResource("otherBeans.properties"));
|
|||
|
|
ctx.refresh();
|
|||
|
|
MyBean myBean = (MyBean) ctx.getBean("myBean");
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 解读ClassPathXmlApplicationContext
|
|||
|
|
|
|||
|
|
1. 从构造函数中，点击追踪父类默认加载：org.springframework.context.support.AbstractApplicationContext
|
|||
|
|
2. 加载构造函数中传入的参数（String... locations），循环处理路径locations
|
|||
|
|
3. 是否刷新加载到的内容
