Spring容器

示例 代码

public class TestBean {
	private String testStr = "1024";
	public String getTestStr() {
		return testStr;
	}
	public void setTestStr(String testStr) {
		this.testStr = testStr;
	}
}

class Test1 {
	public static void main(String[] args) {
		BeanFactory bf = new XmlBeanFactory(new ClassPathResource("org/springframework/beans/demo/TestBeanEntity.xml"));
		TestBean bean1 = (TestBean) bf.getBean("bean1");
		System.out.println(bean1.getTestStr());
	}
}

<?xml version="1.0" encoding="ISO-8859-1"?>
<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-3.0.xsd">

	<bean id="bean1" class="org.springframework.tests.demo.TestBean"/>

</beans>

功能分析

1. 读取配置文件TestBeanEntity.xml
2. 根据文件中的配置，找到对应的类配置，并实例化
3. 调用实例化的实例
