Class SpringProperties

java.lang.Object

org.springframework.core.SpringProperties

public final class SpringProperties
extends Object

Static holder for local Spring properties, i.e. defined at the Spring library level.

Reads a spring.properties file from the root of the Spring library classpath, and also allows for programmatically setting properties through setProperty(java.lang.String, java.lang.String). When checking a property, local entries are being checked first, then falling back to JVM-level system properties through a System.getProperty(java.lang.String) check.

This is an alternative way to set Spring-related system properties such as "spring.getenv.ignore" and "spring.beaninfo.ignore", in particular for scenarios where JVM system properties are locked on the target platform (for example, WebSphere). See setFlag(java.lang.String) for a convenient way to locally set such flags to "true".

3.2.7
