类 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 throughsetProperty(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 aSystem.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 (e.g. WebSphere). See
setFlag(java.lang.String)
for a convenient way to locally set such flags to "true".
