[GitHub] [servicecomb-java-chassis] develpoerX opened a new issue #2349: 微服务配置文件microservice.yaml文件中配置项参数值中存在逗号时，解析成数组。

develpoerX opened a new issue #2349:
URL: https://github.com/apache/servicecomb-java-chassis/issues/2349


   问题描述：
      微服务配置文件microservice.yaml文件中配置项参数值中存在逗号时，解析成数组。eg:在配置文件中写：
   hello:
       sayHelloPrefix: "Hello, ft"
   使用DynamicPropertyFactory.getInstance().getStringproperty（“hello.sayHelloPrefix”, ""）时，获取到的结果为Hello,ft，中间空格被删除。通过定位发现，配置文件参数值，在传递过程中，会经过com.netflix.config包中的ConcurrentMapConfiguration.java文件中的addPropertyImpl（String key, Object value）解析时，默认将value中的逗号解析成数组的形式。

   可以用instanceof来判断是string还是list。参考#2288

   getProperty时，placeholder无法发挥作用  
   可以尝试一下直接使用spirng的enviorment读取

   可以用instanceof来判断是string还是list。
   
   ```java
   @SuppressWarnings("unchecked")
     public List<String> getFileSources() {
   	Object property = finalConfig.getProperty(FILE_SOURCE);
   	if (property instanceof String) {
   	  List<String> result = new ArrayList<>();
   	  result.add((String) property);
   	  return result;
   	} else if (property instanceof List) {
   	  return (List<String>) property;
   	}
   	return new ArrayList<>();
     }
   ```
