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());
        }
    }
