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

@AliasFor(annotation=ResourcePropertySource.class)
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

@AliasFor(annotation=ResourcePropertySource.class)

value

@AliasFor(annotation=ResourcePropertySource.class)
java.lang.String[] value

Indicate the resource location(s) of the JSON file to be loaded.

For example, "classpath:/com/myco/app.json"

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

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

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

默认值:

{}

resourceComparator

@AliasFor(annotation=ResourcePropertySource.class)
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

For example, "classpath:/com/myco/*.json", suppose there are two resources named "a.json" and "b.json" 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.
