Spring Boot(五)----profile文件路径设置

SpringBoot-profile解析

SpringBoot中使用配置文件application.properties和application.yml两种方式，在这两种方式下分别对应各自的profile配置方式。

一．Properties配置文件环境切换

1、application.properties

首先创建application.properties配置文件，配置文件中需要声明切换的环境名称：

1	`spring.profiles.active=prod`

接下来，需要创建两个profile环境，分别为application-dev.properties和application-prod.properties环境，在其中创建一个对应的person类对象。

application-dev.properties

1 2	`person.name=a` `person.age=10`

application-prod.properties

1 2	`person.name=b` `person.age=21`

运行结果如下：

1.当环境切换至dev开发环境下时：

2.当环境切换至prod环境下时：

二．yaml配置文件环境切换

1、application.yml

在yaml文件中，分为三个document，第一个document为默认的配置文件，第二个document为dev1的配置文件，第三部分为dev2的配置文件，在默认的document中使用spring.profile.active设置使用哪个document的配置。

spring:
  profiles:
    active: dev1
---
spring:
  profiles: dev1
person:
  age: 22
  name: zk
 
---
spring:
  profiles: dev2
person:
  age: 24
  name: zjn

设置profile为dev2时，启动运行结果如下：

设置profile为dev1时，启动运行结果如下：

项目的目录结构如下：

下面是一些公共文件

ConfigBean.java

package com.zk.myspringboot;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
public class ConfigBean {
    @Autowired
    Person person;
     
    @RequestMapping("/demo")
    public Person sayHello(){
        return person;
    }
}

MainApp.java

package com.zk.myspringboot;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
 
@SpringBootApplication
public class MainApp {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        SpringApplication.run(MainApp.class, args);
    }
 
}

Person.java

package com.zk.myspringboot;
 
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
 
@Component
@ConfigurationProperties(prefix = "person")
public class Person {
    private String name;
    private Integer age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    @Override
    public String toString() {
        return "Person [name=" + name + ", age=" + age + "]";
    }
     
}

　三、启动设置中切换spring.profiles.active

application.yml

server:
  port: 8080
spring:
  profiles:
    active: prod
---
server:
  port: 8081
spring:
  profiles: dev
 
 
---
server:
  port: 8082
spring:
  profiles: prod
