Spring PropertiesPropertySource

• Author: HuiFer

• 源码阅读仓库: SourceHot-spring

• 全路径: org.springframework.core.env.PropertiesPropertySource

• Properties 是 map 结构。可以做类型转换.

• getPropertyNames 就转换成了父类 MapPropertySource 的方法了
  • map.keySet()

public class PropertiesPropertySource extends MapPropertySource {
   @SuppressWarnings({"rawtypes", "unchecked"})
   public PropertiesPropertySource(String name, Properties source) {
      super(name, (Map) source);
   }
   protected PropertiesPropertySource(String name, Map<String, Object> source) {
      super(name, source);
   }
   @Override
   public String[] getPropertyNames() {
      synchronized (this.source) {
         return super.getPropertyNames();
      }
   }
}
