java工程快速打成可执行jar包的方案

 

经常需要快速打包一个jar，用来在各种环境进行某种测试，怎么快速打包呢？

下面的方法可以1分钟搞定

第一步：添加好配置文件

application.properties

server.port=10000
server.servlet.context-path=/api

 

第二部：配置好pom依赖

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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
    </parent>
    <groupId>com.geektcp.app</groupId>
    <artifactId>thy-app</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>com.geektcp.common</groupId>
            <artifactId>thy-core</artifactId>
            <version>1.0.4</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.1.3.RELEASE</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.0</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <fork>true</fork>
                    <verbose>true</verbose>
                    <encoding>UTF-8</encoding>
                    <showWarnings>false</showWarnings>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>

    </build>
</project>

 

第三步：写两简单的类

package com.geektcp.app;

import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;

/**
 * site: https://github.com/geektcp
 * @author geektcp@163.com on 2023/3/14 15:44.
 */
@Slf4j
@EnableScheduling
@EnableAsync
@ComponentScan(lazyInit = true)
@SpringBootApplication
@ComponentScan({"com.*"})
public class ThyApp {
    public static void main(String[] args) {
        SpringApplication.run(ThyApp.class, args);
    }
}

 

package com.geektcp.app.controller;

import com.geektcp.common.core.generator.IdGenerator;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * site: https://github.com/geektcp
 * @author geektcp@163.com on 2023/3/15 10:00.
 */
@Slf4j
@RestController
@RequestMapping(value = "/test")
public class ApiController {

    @GetMapping(path = "/id")
    public String getId() {
        String id = IdGenerator.getId("id_");
        log.info("generator id: {}", id);
        return id;
    }

}

 

第四步：直接打包

mvn clean package 

 

第五步：运行测试

这是最后一步。

执行启动命令：

java -jar target/thy-app-1.0-SNAPSHOT.jar

 

测试方法（两种环境任选一种）：

linux环境： 

curl http://localhost:10000/api/test/id

每次返回的结果是不一样的。

 

windows环境：

直接在浏览器打开地址：

http://localhost:10000/api/test/id

然后刷新即可

 

日志如下：

$ java -jar target/thy-app-1.0-SNAPSHOT.jar
