获取Spring当前配置的两种方式

package org.example.config;

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.EnvironmentAware;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;

@Configuration
@Slf4j
public class Config1 implements InitializingBean, EnvironmentAware {
    // 如果没有配置会报错，所以必须指定默认值
    @Value("${spring.profiles.active:''}")
    private String envName;
    @Value("${spring.application.name:''}")
    private String appName;
    private Environment environment;

    // 使用注入的方式也可以获取到 Environment 对象
    //@Resource
    //private Environment environment2;


    @Override
    public void afterPropertiesSet() throws Exception {
        log.info("[环境名称]通过Value注解获取 = {}", envName);
        log.info("[应用名称]通过Value注解获取 = {}", appName);
        String property = environment.getProperty("spring.application.name");
        log.info("[应用名称]通过environment获取 = {}", property);
        String[] activeProfiles = environment.getActiveProfiles();
        String[] defaultProfiles = environment.getDefaultProfiles();
        if (activeProfiles.length > 0) {
            log.info("[环境名称]通过environment获取 = {}", activeProfiles[0]);
        } else {
            log.info("[activeProfiles为空]");
        }
        if (defaultProfiles.length > 0) {
            log.info("[环境名称]通过environment获取 = {}", defaultProfiles[0]);
        } else {
            log.info("defaultProfiles为空");
        }
    }

    @Override
    public void setEnvironment(Environment environment) {
        this.environment = environment;
    }
}

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

@Profile({"default"})
