springMvc 之 【javaBean读取属性配置文件中的值】---注解方式

如果在javaBean中读取属性配置文件中的值呢？方法如下：

1、属性配置文件【application.properties】中的部分键值对如下：

# qidao FTP configqidaoFTPHost=10.10.6.12qidaoFTPPort=21qidaoFTPDir=/qidaoFTPUsername=qi2daoqidaoFTPPwd=qi2daoshejiFTPUsername=she2jishejiFTPPwd=she2jiftpDownloadStorePath=D:/新建文件夹

2、在JavaBean里面获取属性配置文件中的值，需注意满足以下条件：

• 必须是在自动依赖注入的类中， 比如@Service注解标识的类；
• 获取的方式：@Value("${键}")，比如@Value("${qidaoFTPUsername}")，将值赋值给@Value注解下面对应的属性。
