This part of the reference documentation covers topics that apply to multiple modules within the core Spring Framework.

1. Spring Properties

SpringProperties is a static holder for properties that control certain low-level aspects of the Spring Framework. Users can configure these properties via JVM system properties or programmatically via the SpringProperties.setProperty(String key, String value) method. The latter may be necessary if the deployment environment disallows custom JVM system properties. As an alternative, these properties may be configured in a file in the root of the classpath — for example, deployed within the application’s JAR file.

The following table lists all currently supported Spring properties.

Table 1. Supported Spring Properties
Name Description


Instructs Spring to use the Introspector.IGNORE_ALL_BEANINFO mode when calling the JavaBeans Introspector. See CachedIntrospectionResults for details.


The mode to use when compiling expressions for the Spring Expression Language.


Instructs Spring to ignore operating system environment variables if a Spring Environment property — for example, a placeholder in a configuration String — isn’t resolvable otherwise. See AbstractEnvironment for details.


Instructs Spring to ignore the components index located in META-INF/spring.components. See Generating an Index of Candidate Components.


Instructs Spring to ignore java.sql.ParameterMetaData.getParameterType completely. See the note in Batch Operations with a List of Objects.


Instructs Spring to ignore a default JNDI environment, as an optimization for scenarios where nothing is ever to be found for such JNDI fallback searches to begin with, avoiding the repeated JNDI lookup overhead. See JndiLocatorDelegate for details.


Instructs Spring to ignore Objenesis, not even attempting to use it. See SpringObjenesis for details.


The default test constructor autowire mode to use if @TestConstructor is not present on a test class. See Changing the default test constructor autowire mode.


The maximum size of the context cache in the Spring TestContext Framework. See Context Caching.


The default enclosing configuration inheritance mode to use if @NestedTestConfiguration is not present on a test class. See Changing the default enclosing configuration inheritance mode.
