public @interface PropertySourceExtension
    A meta-annotation extension for the Spring @PropertySource that has some limitations:
    • The @PropertySource annotation can't auto-refresh the property sources
    • The @PropertySource annotation can't control the order of PropertySource
    • The @PropertySource annotation can't be inherited
    • The PropertySource#value() attribute does not support the resource location wildcards
    • The PropertySource#encoding() attribute does not specify the default encoding for the resource
    从以下版本开始:
    1.0.0

      java.lang.String before
      The relative order before specified PropertySource
      java.lang.String encoding
      A specific character encoding for the given resources.
      java.lang.Class<? extends org.springframework.core.io.support.PropertySourceFactory> factory

      • name

        java.lang.String name
        Indicate the name of this property source.

      • autoRefreshed

        boolean autoRefreshed
        It indicates the property source is auto-refreshed when the configuration is changed.
        返回:
        default value is false
        默认值:
        false

      • first

        boolean first
        Indicates current PropertySource is first order or not If specified , before() and after() will be ignored, or last order.
        返回:
        default value is false
        默认值:
        false

      • before

        java.lang.String before
        The relative order before specified PropertySource

        If not specified , current PropertySource will be added last.

        If first() specified , current attribute will be ignored.

        返回:
        the name of PropertySource, default value is the empty string
        默认值:
        ""

      • after

        java.lang.String after
        The relative order after specified PropertySource

        If not specified , current PropertySource will be added last.

        If first() specified , current attribute will be ignored.

        返回:
        the name of PropertySource, default value is the empty string
        默认值:
        ""

      • value

        java.lang.String[] value
        Indicate the resource(s) of the property source to be loaded.

        For example, "classpath:/com/myco/app.properties" or "file:/path/to/file.xml".

        Resource wildcards (e.g. **/*.properties) also are permitted;

        ${...} placeholders will be resolved against any/all property sources already registered with the Environment.

        Each value will be added to the enclosing Environment as its own property source, and in the order declared.

        默认值:
        {}

      • resourceComparator

        java.lang.Class<? extends java.util.Comparator<org.springframework.core.io.Resource>> resourceComparator
        Indicate the resources to be sorted when value() specifies the resource location wildcards or the same resource names with the different absolute paths.

        For example, "classpath:/com/myco/*.properties", suppose there are two resources named "a.properties" and "b.properties" where two instances of Resource will be resolved, they are the sources of PropertySource, thus it has to sort them to indicate the order of PropertySource that will be added to the enclosing Environment.

        Default is DefaultResourceComparator
