[springboot的注解配置：详见][springboot]

## 一、编写service ##

package org.yq.HelloWorld.service;
    //业务逻辑层
    public class StudentService {
    	//dao 
    //	private StudentDao studentDao  ;
    //	set
    }

## 二、编写spring.xml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="studentService" class="org.yq.HelloWorld.service.StudentService">
    	</bean>
    	
    
    </beans>

## 三、在主配置类HelloWorldApplication.java中添加注解@ImportResource(locations=\{"classpath:spring.xml"\}) ##

package org.yq.HelloWorld;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ImportResource;
    @ImportResource(locations={"classpath:spring.xml"})
    @SpringBootApplication
    public class HelloWorldApplication {
    	public static void main(String[] args) {
    		SpringApplication.run(HelloWorldApplication.class, args);
    	}
    }

## 四、调用service ##

@Autowired
    ApplicationContext context ;//spring ioc容器
    
    @Test
    public void test(){
        StudentService stuService = (StudentService)context.getBean("stuService") ;
        System.out.println(stuService+"=========");
    }

## 五、查看控制台是否有打印 ##
