一 配置xml方式：扫描com包下的bean
<?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
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com"/>
</beans>
com包下一个类：
@Component
@PropertySource("p.properties")
public class Person {
@Value("${name}")
public String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
resource下 p.properties中的文件内容：
name=hahadaxiao
main函数：
public static void main(String[] args){
ApplicationContext context = new ClassPathXmlApplicationContext("a.xml");
Person p = context.getBean("person",Person.class);
System.out.println(p.name);
}
打印：
hahadaxiao
二 注解方式
com包下存在下面这个类，默认扫描Config1所在的包下的Bean
@Configuration
@ComponentScan
public class Config1 {
}
@Component
@PropertySource("p.properties")
public class Person {
@Value("${name}")
public String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public static void main(String[] args){
ApplicationContext context = new AnnotationConfigApplicationContext(Config1.class);
Person p = context.getBean("person",Person.class);
System.out.println(p.name);
}
打印：
hahadaxiao
