【application.properties】

server.port=8080
spring.application.name=myBeanMainmanagement.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/beanshttp://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);}
}
