Element Detail

value

java.lang.String[] value

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

Both traditional and XML-based properties file formats are supported — for example, "classpath:/com/myco/app.properties" or "file:/path/to/file.xml".

Resource location wildcards (e.g. **/*.properties) 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.

Default:

{}

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

ignoreResourceNotFound

boolean ignoreResourceNotFound

Indicate if a failure to find a property resource should be ignored.

true is appropriate if the properties file is completely optional.

Default is false.

Default:

false

encoding

java.lang.String encoding

factory

java.lang.Class<? extends org.springframework.core.io.support.PropertySourceFactory> factory

Specify a custom PropertySourceFactory, if any.

By default, a default factory for standard resource files will be used.

Default is DefaultPropertySourceFactory
