// 方式一： 將配置檔案封裝為一個bean
@Autowired
private ConfigProps configProps;

// 方式二： 通過 Spring 提供的類獲取配置檔案
@Autowired
private Environment environment;

// 方式三： 通過 @Value 註解獲取配置檔案
@Value("${cyf.version}")
private String version;

示例：
--------------------------------------------------------------------------------------------------------------

// 測試一 測試通過封裝的配置Bean 的 toString 方法列印獲取的配置檔案
@Test
public void testProps(){
    System.out.println(configProps);
}

// 測試二 通過 Spring 提供的類獲取配置檔案
@Test
public void testEnvironment(){
    log.info("get version by environment is {}",environment.getProperty(VERSION));
    log.info("get date by environment is {}",environment.getProperty(DATE));
    log.info("get author by environment is {}",environment.getProperty(AUTHOR));
}

// 測試三 通過 @Value 註解獲取配置檔案
@Test
public void testValue(){
    log.info("get version by value is {}",version);
    log.info("get date by value is {}",date);
    log.info("get author by value is {}",author);
}
