spring基本配置
具体文件形式：
applicationContext.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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- 包含整体通用配置 -->
<!-- 包含其他文件的配置 -->
<!-- 导入helloworld.xml -->
<!--resource来源于classpath的根路径-->
<!--错误写法：<import resource="classpath:helloworld.xml"></import>
原因在于强调在编译后，classpath不存在该文件
-->
<import resource="classpath:springbean/helloworld.xml"></import>
</beans>
helloworld.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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd" >
<bean id="helloworld" class="springbean.helloworld">
<property name="username" value="洲洲"></property>
</bean>
</beans>
helloworld类
package springbean;
public class helloworld {
private String username;
public helloworld(){
System.out.println("所谓的焦虑就是书读得太少，而想得又太多");
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public void sqyhello(){
System.out.println("你好世界，我的名字是"+username);
}
}
test测试类
package springbean;
import org.junit.Test;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
public class test {
@Test
public void test(){
//从classpath获取路径
Resource resource= new ClassPathResource("applicationContext.xml");
//获取资源文件创建spring容器
BeanFactory factory=new XmlBeanFactory(resource);
//创建对象
helloworld world=(helloworld) factory.getBean("helloworld");
world.sqyhello();
}
}
结果为：
