spring项目run起来的最小依赖

spring项目跑起来，只需要spring-context这1个依赖项就行，参考下面：

 一、pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.cnblogs.yjmyzz</groupId>
    <artifactId>spring-boot-demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.2.4.RELEASE</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

二、示例代码：

package com.cnblogs.yjmyzz.springbootdemo;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Service;

/**
 * @author 菩提树下的杨过
 */
@ComponentScan("com.cnblogs.yjmyzz")
@Configuration
public class SampleApplication {

    interface SampleService {
        void helloWorld();
    }

    @Service
    class SampleServiceImpl implements SampleService {

        @Override
        public void helloWorld() {
            System.out.println("hello spring");
        }
    }

    public static void main(String[] args) {
        AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(SampleApplication.class);
        SampleService service = context.getBean(SampleService.class);
        service.helloWorld();
    }
}

项目结构：

spring-context的依赖关系如下：
