SpringBoot获取当前运行环境三种方式

综合现有方案，有三种：

注解直接获取
配置Configuration
实现ApplicationContextAware
1、注解直接获取

@Value("${spring.profiles.active}")
private String env;

2、配置Configuration

@Configuration
public class ProfileConfig {

@Autowired
private ApplicationContext context;

public String getActiveProfile() {
return context.getEnvironment().getActiveProfiles()[0];
}
}

3、实现ApplicationContextAware

@Component
public class SpringUtils implements ApplicationContextAware {
private static ApplicationContext applicationContext;

@Override
public void setApplicationContext(ApplicationContext applicationContext)
throws BeansException {
if (SpringUtils.applicationContext == null) {
SpringUtils.applicationContext = applicationContext;
}
}

public static ApplicationContext getApplicationContext() {
return applicationContext;
}


public static Object getBean(String name) {
return getApplicationContext().getBean(name);
}


public static <T> T getBean(Class<T> clazz) {
return getApplicationContext().getBean(clazz);
}

public static <T> T getBean(String name, Class<T> clazz) {
return getApplicationContext().getBean(name, clazz);
}

/**
* 获取当前环境
*/
public static String getActiveProfile() {
return context.getEnvironment().getActiveProfiles()[0];
}
}
