SpringBoot-----读取xml配置bean(@ImportResource)_springboot service impl xml bean interface-优快云博客

本文介绍如何在SpringBoot项目中整合旧的XML配置文件，通过示例展示了如何使用@ImportResource注解导入XML配置，以及如何在控制器中注入并使用XML配置的Bean对象。

1、应用场景

旧框架SSM项目移行到SpringBoot中，xml配置文件很齐全，就可以省去配置的麻烦，直接读取旧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读取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、应用xml中的bean对象

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("[***访问地址***]"+super.getMessage("member.add.action"));
		return super.getMessage("welcome.msg", mid);
	}
	
	public String msg(){
		return (messageService.getMessage());
	}
	
}

5、Service类

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、测试

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());
	}

}
