SpringBoot如何读取xml配置bean(@ImportResource)

这篇文章主要介绍了SpringBoot如何读取xml配置bean(@ImportResource)，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教

读取xml配置bean(@ImportResource)

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());
    } 
}
