Spring Framework 6.1.4 · org.springframework.beans.StandardBeanInfoFactory

BeanInfoFactory implementation that performs standard java.beans.Introspector inspection.

To be configured via a META-INF/spring.factories file with the following content: org.springframework.beans.BeanInfoFactory=org.springframework.beans.StandardBeanInfoFactory

Ordered at Ordered#LOWEST_PRECEDENCE to allow other user-defined BeanInfoFactory types to take precedence.

Field Summary

Modifier and Type	Field and Description
public static final String	IGNORE_BEANINFO_PROPERTY_NAME System property that instructs Spring to use the `Introspector#IGNORE_ALL_BEANINFO` mode when calling the JavaBeans `Introspector`: "spring.beaninfo.ignore", with a value of "true" skipping the search for `BeanInfo` classes (typically for scenarios where no such classes are being defined for beans in the application in the first place).
private static final boolean	shouldIntrospectorIgnoreBeaninfoClasses

Constructor Summary

Access	Constructor and Description

Method Summary

public BeanInfo	getBeanInfo(Class<?> the bean class beanClass) Implements org.springframework.beans.BeanInfoFactory.getBeanInfo. Return the bean info for the given class, if supported.
public int	getOrder() Implements org.springframework.core.Ordered.getOrder. Get the order value of this object.

IGNORE_BEANINFO_PROPERTY_NAME	back to summary
public static final String IGNORE_BEANINFO_PROPERTY_NAME System property that instructs Spring to use the `Introspector#IGNORE_ALL_BEANINFO` mode when calling the JavaBeans `Introspector`: "spring.beaninfo.ignore", with a value of "true" skipping the search for `BeanInfo` classes (typically for scenarios where no such classes are being defined for beans in the application in the first place). The default is "false", considering all `BeanInfo` metadata classes, like for standard `Introspector#getBeanInfo(Class)` calls. Consider switching this flag to "true" if you experience repeated ClassLoader access for non-existing `BeanInfo` classes, in case such access is expensive on startup or on lazy loading. Note that such an effect may also indicate a scenario where caching doesn't work effectively: Prefer an arrangement where the Spring jars live in the same ClassLoader as the application classes, which allows for clean caching along with the application's lifecycle in any case. For a web application, consider declaring a local `org.springframework.web.util.IntrospectorCleanupListener` in `web.xml` in case of a multi-ClassLoader layout, which will allow for effective caching as well. See Also `Introspector#getBeanInfo(Class, int)`

public BeanInfo getBeanInfo(Class<?> beanClass) throws IntrospectionException

Implements org.springframework.beans.BeanInfoFactory.getBeanInfo.

Doc from org.springframework.beans.BeanInfoFactory.getBeanInfo.

Return the bean info for the given class, if supported.

getOrder back to summary

getOrder	back to summary
public int getOrder() Implements org.springframework.core.Ordered.getOrder. Doc from org.springframework.core.Ordered.getOrder. Get the order value of this object. Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet `load-on-startup` values). Same order values will result in arbitrary sort positions for the affected objects. Returns:int the order value Annotations @Override

public int getOrder()

Implements org.springframework.core.Ordered.getOrder.

Doc from org.springframework.core.Ordered.getOrder.

Get the order value of this object.

Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).

Same order values will result in arbitrary sort positions for the affected objects.

Returns:int

the order value
