spring boot 實戰 / mvn spring-boot:run 參數詳解

spring spring boot maven 實戰

概述

  Spring boot項目通常情況下有如下幾種啟動方式:

  • 通過主類啟動。
  • 通過spring-boot的maven插件spring-boot-maven-plugin方式啟動。
  • 通過可執行jar/war包方式啟動。
  • 通過Servlet容器啟動,如Tomcat、Jetty等。

  今天我們來聊一下spring boot的maven插件spring-boot-maven-plugin啟動過程中的profiles問題。首先,我們前往網站SPRING INITIALIZR,參照下圖創建一個名稱為demo的spring boot項目。

技術分享圖片

  點擊按鈕"Generate Poject alt + Enter",將得到一個名稱為demo.zip的文件,解壓該文件,將得到一個名為demo的目錄。

  我們接下來,將以這個demo項目為例展開講解。

項目結構

  為了演示我們後面的實驗,我們對項目demo做一些調整,調整後的目錄結構如下如示。

  這裏簡單說一下,我的電腦上安裝的是Linux mint 18.3系統,所以在目錄展示上可能與大家使用的Windows 7/8/10等風格上不一致,這個沒有關系的,希望大家不要感覺到奇怪。

  這裏我們將環境粗略劃分為開發環境(dev)、測試環境(test)、生產環境(prod),主要是為了演示spring boot的spring-boot maven插件的profiles與spring boot中spring.profiles的用對應關系及相關用法。

  接下來我們先簡要瀏覽一下上述目錄中的幾個關鍵文件的內容。

pom.xml內容如下:

項目啟動主類DemoApplication.java內容如下:

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

application.yml內容如下:

spring:
  profiles:
    active: dev

開發環境配置文件application-dev.yml內容如下:

server:
  port: 8080

生產環境配置文件application-prod.yml內容如下:

server:
  port: 9999

測試環境配置文件application-test.yml內容如下:

server:
  port: 7829

測試主類DemoApplicationTests.java內容如下:

package com.example.demo;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {

    @Test
    public void contextLoads() {
    }

}

啟動參數

默認啟動參數

  結合上面的文件內容,我們可以看出,整個系統已經將開發環境設置為了默認開發環境,所以,默認啟動參數是針對開發環境的。

  那麽在如何命令行添加諸如test、prod之類的profiles參數呢,為此,我試了好久,後來終於在Spring Boot Maven Plugin找到了想要的答案,具體如下圖所示。

至此任務完成。

總結

  從上面的實例我們可以看到,如果在項目中通過spring.profiles定義了多個環境:

application-xxx.yml

用maven插件spring-boot啟動時,可以用

mvn spring-boot:run -Dspring-boot.run.profiles=xxx

來啟動。
