SpringBoot加载XML文件，通过IOC示例_springboot 加载springxml-优快云博客

该文章展示了如何在SpringBoot应用中通过XML文件定义Bean，并使用@ImportResource注解加载XML配置。在bean.xml中定义了一个名为testBeanLoad的Bean，其类为com.book.springtest.service.LoadBeanFromXMLBySpringBoot。主应用类SpringTestApplication导入了XML配置，并通过@SpringBootTest注解的测试类验证Bean是否成功加载。

SpringBoot的XML规范要求。

定义Bean 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="testBeanLoad" class="com.book.springtest.service.
    LoadBeanFromXMLBySpringBoot"></bean>
    
</beans>

定义被加载的Bean

package com.book.springtest.service;
import lombok.extern.slf4j.Slf4j;

@Slf4j
public class LoadBeanFromXMLBySpringBoot {

	public LoadBeanFromXMLBySpringBoot(){
		log.info("running the contruct of LoadBeanFromXMLBySpringBoot");
	}
}

@ImportResource(locations = {“classpath:bean.xml”})

@SpringBootApplication
@ImportResource(locations = {"classpath:bean.xml"})
public class SpringTestApplication {
	public static void main(String[] args) {
		SpringApplication app = new SpringApplication(SpringTestApplication.class);
		//app.setDefaultProperties(Collections.singletonMap("server.port", "8085"));
		//SpringApplication.run(SpringTestApplication.class, args);
		app.run(args);
	}
}

测试Case

@SpringBootTest
@Slf4j
class LoadBeanFromXMLBySpringBootTest {

	@Resource
	private ConfigurableApplicationContext ioc;
	
	@Test
	void test() {
		if(ioc.containsBean("testBeanLoad")) {
			log.info("this class testBeanLoad has been loadding");
		}else {
			log.info("this class testBeanLoad hasn't been loadded");
		}
	}
}
