spring源码分析1

强烈推介IDEA2020.2破解激活，IntelliJ IDEA 注册码，2020.2 IDEA 激活码

1，学习spring源码笔记

下面是各个类的作用

容器的基础是xmlBeanFactory

XmlBeanFactory bf = new XmlBeanFactory (new ClassPathResource(“beanFactoryTest.xml”))

classPathResource是一个资源统一解析器

@Override

	public InputStream getInputStream() throws IOException {

		InputStream is;

		if (this.clazz != null) {

			is = this.clazz.getResourceAsStream(this.path);

		}

		else if (this.classLoader != null) {

			is = this.classLoader.getResourceAsStream(this.path);

		}

		else {

			is = ClassLoader.getSystemResourceAsStream(this.path);

		}

		if (is == null) {

			throw new FileNotFoundException(getDescription() + " cannot be opened because it does not exist");

		}

		return is;

	}

通过classLoader进行加载配置文件资源。

super（parentBeanFactory）调用 AbstractAutowireCapableBeanFactory

	/**

	 * Create a new AbstractAutowireCapableBeanFactory.

	 */

	public AbstractAutowireCapableBeanFactory() {

		super();

		ignoreDependencyInterface(BeanNameAware.class);

		ignoreDependencyInterface(BeanFactoryAware.class);

		ignoreDependencyInterface(BeanClassLoaderAware.class);

	}

加载Bean
