@ImportResource

1、

@ImportResource(locations = {"classpath:beantest.xml"})标注到启动类上，从类路径下加载xml文件，通过Application.getbean获取xml配置对象

一开始写错了// @PropertySource(value = { "class:beantest.xml" })

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
import org.springframework.context.annotation.PropertySource;
@ImportResource(locations = {"classpath:beantest.xml"})
@SpringBootApplication
public class Demo2Application {
//	@PropertySource(value = { "class:beantest.xml" })
	public static void main(String[] args) {
		SpringApplication.run(Demo2Application.class, args);
	}

}

　　bean文件

<?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/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

   <bean id="mao" class="com.example.demo.Maomao">
   <property name="name" value="maomaomiaomiao"></property>
   </bean>

</beans>
