• Spring Properties

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

Spring Properties

{api-spring-framework}/core/SpringProperties.html[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 spring.properties 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
spring.beaninfo.ignore	Instructs Spring to use the Introspector.IGNORE_ALL_BEANINFO mode when calling the JavaBeans Introspector. See {api-spring-framework}/beans/CachedIntrospectionResults.html#IGNORE_BEANINFO_PROPERTY_NAME[CachedIntrospectionResults] for details.
spring.expression.compiler.mode	The mode to use when compiling expressions for the Spring Expression Language.
spring.getenv.ignore	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 {api-spring-framework}/core/env/AbstractEnvironment.html#IGNORE_GETENV_PROPERTY_NAME[AbstractEnvironment] for details.
spring.index.ignore	Instructs Spring to ignore the components index located in META-INF/spring.components. See Generating an Index of Candidate Components.
spring.jdbc.getParameterType.ignore	Instructs Spring to ignore java.sql.ParameterMetaData.getParameterType completely. See the note in Batch Operations with a List of Objects.
spring.jndi.ignore	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 {api-spring-framework}/jndi/JndiLocatorDelegate.html#IGNORE_JNDI_PROPERTY_NAME[JndiLocatorDelegate] for details.
spring.objenesis.ignore	Instructs Spring to ignore Objenesis, not even attempting to use it. See {api-spring-framework}/objenesis/SpringObjenesis.html#IGNORE_OBJENESIS_PROPERTY_NAME[SpringObjenesis] for details.
spring.test.constructor.autowire.mode	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.
spring.test.context.cache.maxSize	The maximum size of the context cache in the Spring TestContext Framework. See Context Caching.
spring.test.enclosing.configuration	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.
