application.properties

server.name=Linux
server.host=192.168.0.1,172.16.0.1

         @Value("${server.name}")private String name;@Value("${server.name:Windows}") 如果application.properties没有配置server.name那么默认值将是 Windowsprivate String name;@Value("${app.name:@null}") // app.name = nullprivate String name;@Value("#{'${server.host}'.split(',')}") private List<String> host;

@PropertySource("classpath:/config.properties}") 忽略FileNotFoundException，当配置文件不存在系统抛出FileNotFoundException并终止程序运行，ignoreResourceNotFound=true 会跳过使程序能够正常运行
@PropertySource(value="classpath:config.properties", ignoreResourceNotFound=true)      

载入多个配置文件

@PropertySources({  @PropertySource("classpath:config.properties"),  @PropertySource("classpath:db.properties")
})
