【application.properties】

spring.application.name=myBeanMain

management.server.port=7001
management.endpoints.web.exposure.include=*

【my_beans.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/beans
                           http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="mainBean2" class="com.chz.myBeanMain.bean.MainBean2"></bean>

</beans>

注意xml里面定义了一个【mainBean2】

【MainBean1.java】

package com.chz.myBeanMain.bean;

@Slf4j
@Getter
@Setter
@Component
public class MainBean1 {

    public MainBean1()
    {
        log.info("chz >>> MainBean1.<init>()");
    }

    private String name = "MainBean1";

}

【MainBean2.java】

package com.chz.myBeanMain.bean;

@Slf4j
@Getter
@Setter
//@Component   // 注意MainBean2是没有【@Component】注解的
public class MainBean2 {

    public MainBean2()
    {
        log.info("chz >>> MainBean1.<init>()");
    }

    private String name = "MainBean2";

}

【MainController.java】

package com.chz.myBeanMain.controller;

@Slf4j
@RestController
@RequestMapping("/main")
public class MainController {

    @Autowired(required = false)
    private MainBean1 mainBean1;

    @Autowired(required = false)
    private MainBean2 mainBean2;        // 这里注入【MainBean2】

    @GetMapping("/mainBean1")
    public String mainBean1() {
        return "mainBean1: " + mainBean1.getName();
    }

    @GetMapping("/mainBean2")
    public String mainBean2() {
        return "mainBean2: " + mainBean2.getName();
    }
}

【MyBeanMainTest.java】

package com.chz.myBeanMain;

@ImportResource(locations = {"classpath:my_beans.xml"})        // 这里导入【MainBean2】的xml
@SpringBootApplication
public class MyBeanMainTest {

    public static void main(String[] args) {
        SpringApplication.run(MyBeanMainTest.class, args);
    }
}
