Spring项目运行依赖spring-contex解析

作者:菩提树下的杨过

这篇文章主要介绍了Spring项目运行依赖spring-contex解析,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

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:
