maven assembly打包生成Java应用启动脚本bat和sh

## 1. maven插件介绍 ##

springboot应用通过maven插件appassembler-maven-plugi生成启动脚本bat和sh。根据官网介绍，这个插件主要用于生成启动 java应用程序的脚本，能将项目依赖jar能够打包目录中，并且它们加入启动脚本类路径中。

主要命令  
appassembler:assemble 打包项目并且配置bin 启动脚本，可以理解为使用类似spring-boot-maven-plugin打包出来项目，可以通过java -jar 方式启动项目，但是不支持stop、satus、restart这些操作，比较原始。  
appassembler:create-repository 创建一个 appassembler 存储库，就是将工程打成jar  
appassembler:generate-daemons 生成基于 JSW 的守护进程包装器,大多数人都是使用这个。

参考文档

## 2. 生成启动脚本 ##

### 2.1 创建springboot应用 ###

### 2.2 创建启动测试类 ###

MavenAssemblyDemoApplication

package com.zrj.maven.assembly.demo;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * MavenAssemblyDemoApplication
     *
     * @author zrj
     * @since 20221117
     */
    @RestController
    @SpringBootApplication
    public class MavenAssemblyDemoApplication {
        
    
        public static void main(String[] args) {
        
            SpringApplication.run(MavenAssemblyDemoApplication.class, args);
        }
    
        /**
         * Hello World!
         * If you open a web browser to localhost:8080, you should see the following output:
         *
         * @see 1 https://docs.spring.io/spring-boot/docs/2.7.5/reference/htmlsingle/
         */
        @RequestMapping("/")
        String home() {
        
            long currentTime = System.currentTimeMillis();
            String helloTime = currentTime + "：Hello World!";
            System.out.println(helloTime);
            return helloTime;
        }
    }

### 2.3 maven依赖配置 ###

## 3. 测试验证 ##

### 3.1 执行命令 ###

执行命令或者使用idea  
执行命令：maven install  
idea：maven-lifecycle依次执行clean，install

### 3.2 生成脚本 ###

![在这里插入图片描述][4b8cd779befe486da9dd66b244a424df.png]

### 3.3 启动脚本验证 ###

./start.bat 或者./start.sh
