Class StandardBeanInfoFactory

java.lang.Object

org.springframework.beans.StandardBeanInfoFactory

All Implemented Interfaces:

BeanInfoFactory, Ordered

Direct Known Subclasses:

ExtendedBeanInfoFactory

public class StandardBeanInfoFactory
extends Object
implements BeanInfoFactory, Ordered

BeanInfoFactory implementation that performs standard 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.

Since:

6.0

Fields

Modifier and Type	Field	Description
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).

Field Details

IGNORE_BEANINFO_PROPERTY_NAME

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 IntrospectorCleanupListener in web.xml in case of a multi-ClassLoader layout, which will allow for effective caching as well.

Method Details

getBeanInfo

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

Description copied from interface: BeanInfoFactory

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

Specified by:

getBeanInfo in interface BeanInfoFactory

Parameters:

beanClass - the bean class

Returns:

the BeanInfo, or null if the given class is not supported

Throws:

IntrospectionException - in case of exceptions

getOrder

public int getOrder()

Description copied from interface: Ordered

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.

Specified by:

getOrder in interface Ordered

Returns:

the order value
