Spring EnumerablePropertySource

  • Author: HuiFer

  • 源码阅读仓库: SourceHot-spring

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

  • 在这个类中定义了一个抽象方法getPropertyNames 用来获取所有的 property 的名称
  1.     public abstract String[] getPropertyNames();
  • 整体代码如下
  1. public abstract class EnumerablePropertySource<T> extends PropertySource<T> {
  3.     public EnumerablePropertySource(String name, T source) {
  4.         super(name, source);
  5.     }
  7.     protected EnumerablePropertySource(String name) {
  8.         super(name);
  9.     }
  12.     /**
  13.      * Return whether this {@code PropertySource} contains a property with the given name.
  14.      * <p>This implementation checks for the presence of the given name within the
  15.      * {@link #getPropertyNames()} array.
  16.      *
  17.      * 在属性列表中是否存在 properties
  18.      * @param name the name of the property to find
  19.      */
  20.     @Override
  21.     public boolean containsProperty(String name) {
  22.         return ObjectUtils.containsElement(getPropertyNames(), name);
  23.     }
  25.     /**
  26.      * Return the names of all properties contained by the
  27.      * 获取所有的 properties 名称
  28.      * {@linkplain #getSource() source} object (never {@code null}).
  29.      */
  30.     public abstract String[] getPropertyNames();
  32. }
