通过spring-context创建可执行jar

1、新建一个maven工程；

 

 2、pom.xml中引入spring-context dependency

	<dependencies>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context</artifactId>
			<version>${spring.version}</version>
		</dependency>		
	</dependencies>

 

 3、添加maven的compiler 和 jar plugin

<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>3.1</version>
				<configuration>
					<encoding>${project.build.sourceEncoding}</encoding>
					<source>${java.version}</source>
					<target>${java.version}</target>
					 <compilerArgs>
                      </compilerArgs>
				</configuration>
			</plugin>
			
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-jar-plugin</artifactId>
				<configuration>
					<archive>
						<manifest>
							<!-- 指定入口函数 -->
							<mainClass>com.huatech.core.Bootstrap</mainClass>
							<!-- 是否添加依赖的jar路径配置 -->
							<addClasspath>true</addClasspath>
							<!-- 依赖的jar包存放位置，和生成的jar放在同一级目录下 -->
							<classpathPrefix>lib</classpathPrefix>
						</manifest>
					</archive>
				</configuration>
			</plugin>
			
		</plugins>
	</build>

 

4、启动类添加main方法

package com.huatech.core;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.scheduling.annotation.EnableScheduling;


@ComponentScan(basePackages="com.huatech.core")
@EnableScheduling
public class Bootstrap {
	
	@SuppressWarnings("resource")
	public static void main(String[] args) {
		System.out.println("starting jar-demo ...");
		AnnotationConfigApplicationContext context = 
				new AnnotationConfigApplicationContext(Bootstrap.class);
//		//1. 初始化bean读取器和扫描器
//		AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();
//		//2.注册bean配置类
//		context.register(Bootstrap.class);
//		context.register(ScheduleConfig.class);
//		//3.刷新上下文
//		context.refresh();
		// 优雅停机
		context.registerShutdownHook();
	}

}

 

5、添加一个测试类

package com.huatech.core.service;

import java.util.Date;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class TestSchedule {
	
	
	@Scheduled(fixedDelay = 2000)
	public void log(){
		System.out.println("["+new Date() +"]--");
	}
	

}
