@Configuration
public class ScheduleConfig {
@Value("${mes.home}")
public String cbs;
@Bean()
// /@Scope(value = "prototype") 多例bean，修改yml，会立即生效
public Properties loadProperties() throws IOException {
File file = new File(cbs + File.separator + "schedule.properties");
if(!file.exists()){
file.createNewFile();
// Properties格式文件的写入 file
try (BufferedInputStream bis = new BufferedInputStream( getClass().getClassLoader()
.getResourceAsStream("schedule.properties"));BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file))) {
Properties props = new Properties();
props.load(bis); // 将“输入流”加载至Properties集合对象中
props.store(bos, "定时任务");
} catch (IOException e) {
e.printStackTrace();
}
}
Properties props = new Properties();
try (BufferedInputStream bis = new BufferedInputStream( new FileInputStream(file))) {
props.load(bis);
} catch (IOException e) {
e.printStackTrace();
}
return props;
}
}
其中 @Value("${mes.home}") 中 mes,home 为属性文件中配置本地路径
schedule.properties 为resource下配置文件，也是读取文件，本文主要目的将resource 下的schdule.properties 属性写到到外部配置 ${mes.home}/schedule.properties
