概述

  Spring boot項目一般狀況下有以下幾種啓動方式：html

  • 經過主類啓動。
  • 經過spring-boot的maven插件spring-boot-maven-plugin方式啓動。
  • 經過可執行jar/war包方式啓動。
  • 經過Servlet容器啓動，如Tomcat、Jetty等。

  今天咱們來聊一下spring boot的maven插件spring-boot-maven-plugin啓動過程當中的profiles問題。首先，咱們前往網站SPRING INITIALIZR，參照下圖建立一個名稱爲demo的spring boot項目。java

SPRING INITIALIZR

  點擊按鈕"Generate Poject alt + Enter"，將獲得一個名稱爲demo.zip的文件，解壓該文件，將獲得一個名爲demo的目錄。git

  咱們接下來，將以這個demo項目爲例展開講解。web

項目結構

  爲了演示咱們後面的實驗，咱們對項目demo作一些調整，調整後的目錄結構以下如示。spring

  這裏簡單說一下，個人電腦上安裝的是Linux mint 18.3系統，因此在目錄展現上可能與你們使用的Windows 7/8/10等風格上不一致，這個沒有關係的，但願你們不要感受到奇怪。apache

  這裏咱們將環境粗略劃分爲開發環境(dev)、測試環境(test)、生產環境(prod)，主要是爲了演示spring boot的spring-boot maven插件的profiles與spring boot中spring.profiles的用對應關係及相關用法。tomcat

  接下來咱們先簡要瀏覽一下上述目錄中的幾個關鍵文件的內容。app

項目啓動主類DemoApplication.java內容以下：ide

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內容以下：

spring:
  profiles:
    active: dev

server:
  port: 8080

生產環境配置文件application-prod.yml內容以下：

server:
  port: 9999

測試環境配置文件application-test.yml內容以下：

server:
  port: 7829

測試主類DemoApplicationTests.java內容以下：

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() {
    }

}

啓動參數

默認啓動參數

  結合上面的文件內容，咱們能夠看出，整個系統已經將開發環境設置爲了默認開發環境，因此，默認啓動參數是針對開發環境的。

  那麼在如何命令行添加諸如test、prod之類的profiles參數呢，爲此，我試了很久，後來終於在Spring Boot Maven Plugin找到了想要的答案，具體以下圖所示。

  通過測試，發現徹底知足要求，具體介紹以下：

至此任務完成。

總結

  從上面的實例咱們能夠看到，若是在項目中經過spring.profiles定義了多個環境：

application-xxx.yml

用maven插件spring-boot啓動時，能夠用

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

來啓動。
