Spring Cloud微服务实战打造企业级优惠券系统 3-4 SpringBoot配置文件加载顺序

0　　　　课程地址

https://coding.imooc.com/lesson/380.html#mid=28272

1　　　　浓缩精华

1.1　　3.1,3.2

2　　　　个人关注

2.1　　3.3

3　　　　课程内容

3.1　　同一目录下的application和bootstrap

bootstrap优先级高于application，优先被加载
bootstrap 用于应用程序上下文的引导阶段，由父ApplicationContext加载bootstrap是系统级别的配置（不变的参数），
application是应用级别的配置

3.2　　不同位置的配置文件加载顺序（优先级）

sfile:/config/-优先级最高（项目根路径下的config）
file:./-优先级第二（项目根路径下）
classpath:/config/-优先级第三（项目resources/config下）
classpath/-优先级第四（项目resources目录下）高优先级覆盖低优先级相同配置多个配置文件互补

3.3　　注意事项

跟路径下的配置文件不会被打包
不同位置的配置文件优先级顺序最好将配置spring.profiles.active 排除在外

4　　　　代码演练

4.1　　配置application.xml demo

application.yml配置

spring:
  application:
    name: imooc_springboot_study

server:
#端口号
  port: 8081
  servlet:
  #前缀
    context-path: /imooc

启动类

package com.imooc.springboot.application;

import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.WebApplicationType;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;

/**

@SpringBootApplication
public class SpringBootStudyApplication {
    public static void main(String [] args){
        //第一种方式启动
        SpringApplication.run(SpringBootStudyApplication.class,args);

        //第二种方式启动
        /*SpringApplication springApplication = new SpringApplication(SpringBootStudyApplication.class);
        //关掉打印logo相关日志
        springApplication.setBannerMode(Banner.Mode.OFF);
        //非wub启动，控制台启动后会关闭，不会一直保持开启状态
        springApplication.setWebApplicationType(WebApplicationType.NONE);
        springApplication.run(args);*/

        //第三种方式启动 链式调用
       /* new SpringApplicationBuilder(SpringBootStudyApplication.class)
                //.bannerMode(Banner.Mode.OFF)
                .web(WebApplicationType.NONE).run(args);*/
    }

}

4.2　　多个配置文件选择

application.yml

spring:
  profiles:
 #  active: prod 生效的配置文件
    active: dev
  application:
    name: imooc_springboot_study

server:
#端口号
#  port: 8081
#  servlet:
#    context-path: /imooc

application-dev.yml

server:
#端口号
  port: 8082
  servlet:
    context-path: /imooc-dev

启动类

package com.imooc.springboot.application;

4.3　　不同路径下优先级顺序测试

根路径 config文件夹下:application.xml

server:
#端口号
  port: 8085
#  servlet:
#    context-path: /imooc

常规resource路径下:application.xml

spring:
 # profiles:
 #  active: prod
 #注意：这里不能有profiles active: dev，否则 按application-dev配置文件的端口号
 #   active: dev
  application:
    name: imooc_springboot_study
