這篇文章主要介紹了SpringBoot如何讀取xml配置bean(@ImportResource)，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

讀取xml配置bean(@ImportResource)

1、應用場景

舊框架SSM項目移行到SpringBoot中，xml配置文件很齊全，就可以省去配置的麻煩，直接讀取舊xml文件

2、spring-common.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"
? ? xmlns:p="http://www.springframework.org/schema/p"
? ? xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">? ??
? ? <bean id="msgService" class="com.zemel.micorboot.service.impl.MessageServiceImpl"></bean>? ??
? ? </beans>

3、SpringBoot讀取xml

package com.zemel.micorboot;?
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
?
/**
?* Hello world!
?*
?*/
@SpringBootApplication
@ImportResource(locations={"classpath:xml/spring-common.xml"})
public class App?
{
? ? public static void main( String[] args )
? ? {
? ? ? ? SpringApplication.run(App.class, args);
? ? }
}

4、應用xml中的bean對象

package com.zemel.micorboot.controller;?
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;?
import com.zemel.micorboot.base.AbstractBaseController;
import com.zemel.micorboot.service.MessageService;
?
@RestController
public class MessageController extends AbstractBaseController {
?? ?
?? ?@Autowired
?? ?private MessageService messageService;?? ?
?
?? ?@GetMapping("/echo")
?? ?public String echo(String mid){
?? ??? ?System.out.println("[***訪問地址***]"+super.getMessage("member.add.action"));
?? ??? ?return super.getMessage("welcome.msg", mid);
?? ?}
?? ?
?? ?public String msg(){
?? ??? ?return (messageService.getMessage());
?? ?}?? ?
}

5、Service類

package com.zemel.micorboot.service; 
public interface MessageService { 
	String getMessage();	
}

package com.zemel.micorboot.service.impl; 
import com.zemel.micorboot.service.MessageService; 
public class MessageServiceImpl implements MessageService{ 
	@Override
	public String getMessage() {
		return "my message...";
	}
}

6、測試

package com.zemel.micorboot.controller;?
import javax.annotation.Resource;?
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;?
import com.zemel.micorboot.App;
?
@SpringBootTest(classes=App.class)
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class MessageControllerTest {?
?? ?@Resource
?? ?private MessageController mc;
?? ?
?? ?@Test
?? ?public void testEcho() {?? ??? ?
?? ??? ?System.out.println(this.mc.echo("mldnjava"));?? ??? ?
?? ?}
?? ?
?? ?@Test
?? ?public void testMsg(){
?? ??? ?System.out.println(this.mc.msg());
?? ?}?
}
