This part of the reference documentation covers topics that apply to multiple modules |
|
within the core Spring Framework. |
|
|
|
|
|
[[appendix-spring-properties]] |
|
== 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. |

.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 |
|
<<core.adoc#expressions-compiler-configuration, 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 <<core.adoc#beans-scanning-index, Generating an Index |
|
of Candidate Components>>. |
|
|
|
| `spring.jdbc.getParameterType.ignore` |
|
| Instructs Spring to ignore `java.sql.ParameterMetaData.getParameterType` completely. |
|
See the note in <<data-access.adoc#jdbc-batch-list, 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 <<testing.adoc#integration-testing-annotations-testconstructor, |
|
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 |
|
<<testing.adoc#testcontext-ctx-management-caching, Context Caching>>. |
|
|
|
| `spring.test.enclosing.configuration` |
|
| The default _enclosing configuration inheritance mode_ to use if |
|
`@NestedTestConfiguration` is not present on a test class. See |
|
<<testing.adoc#integration-testing-annotations-nestedtestconfiguration, Changing the |
|
default enclosing configuration inheritance mode>>. |
