SpringBoot读取多环境配置文件的几种方式

//applicaiton.properties配置
spring.redis.host: 127.0.0.1
spring.redis.port: 3306
spring.redis.password :123456

@Component
@PropertySources(value = "classpath:application.properties")
public class RedisProperties {
    @Value("${spring.redis.host}")
    private String host;
    @Value("${spring.redis.port}")
    private String port;
    @Value("${spring.redis.password}")
    private int password;
}

//需要我们在applicaiton.properties设置环境变量
spring.profiles.actives = dev

//application.yml
spring:
  redis:
    host: 127.0.0.1
    port: 6379
    password: password
