## org.springframework.beans.factory.config
Class CustomEditorConfigurer

    java.lang.Object
      org.springframework.beans.factory.config.CustomEditorConfigurer

All Implemented Interfaces:
  BeanClassLoaderAware, BeanFactoryPostProcessor, Ordered

    public class CustomEditorConfigurer

extends Object
implements BeanFactoryPostProcessor, BeanClassLoaderAware, Ordered

`BeanFactoryPostProcessor` implementation that allows for convenient registration of custom `property editors`.

In case you want to register `PropertyEditor` instances, the recommended usage as of Spring 2.0 is to use custom `PropertyEditorRegistrar` implementations that in turn register any desired editor instances on a given `registry`. Each PropertyEditorRegistrar can register any number of custom editors.

     <bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
       <property name="propertyEditorRegistrars">
         <list>
           <bean class="mypackage.MyCustomDateEditorRegistrar"/>
           <bean class="mypackage.MyObjectEditorRegistrar"/>
         </list>
       </property>
     </bean>

It's perfectly fine to register `PropertyEditor` classes via the `customEditors` property. Spring will create fresh instances of them for each editing attempt then:

     <bean id="customEditorConfigurer" class="org.springframework.beans.factory.config.CustomEditorConfigurer">
       <property name="customEditors">
         <map>
           <entry key="java.util.Date" value="mypackage.MyCustomDateEditor"/>
           <entry key="mypackage.MyObject" value="mypackage.MyObjectEditor"/>
         </map>
       </property>
     </bean>

Note, that you shouldn't register `PropertyEditor` bean instances via the `customEditors` property as `PropertyEditor`s are stateful and the instances will then have to be synchronized for every editing attempt. In case you need control over the instantiation process of `PropertyEditor`s, use a `PropertyEditorRegistrar` to register them.

Also supports "java.lang.String[]"-style array class names and primitive class names (e.g. "boolean"). Delegates to `ClassUtils` for actual class name resolution.

NOTE: Custom property editors registered with this configurer do not apply to data binding. Custom editors for data binding need to be registered on the `DataBinder`: Use a common base class or delegate to common PropertyEditorRegistrar implementations to reuse editor registration there.

Field Detail

### logger

    protected final Log logger

Constructor Detail

### CustomEditorConfigurer

    public CustomEditorConfigurer()

Method Detail

### setOrder

    public void setOrder(int order)

### getOrder

    public int getOrder()

  Description copied from interface: `Ordered`
  Return the order value of this object, with a higher value meaning greater in terms of sorting.

  Normally starting with 0, with `Integer.MAX_VALUE` indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

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

  Specified by:
    `getOrder` in interface `Ordered`
  Returns:
    the order value

### setPropertyEditorRegistrars

    public void setPropertyEditorRegistrars(PropertyEditorRegistrar[] propertyEditorRegistrars)

  Specify the `PropertyEditorRegistrars` to apply to beans defined within the current application context.

  This allows for sharing `PropertyEditorRegistrars` with `DataBinders`, etc. Furthermore, it avoids the need for synchronization on custom editors: A `PropertyEditorRegistrar` will always create fresh editor instances for each bean creation attempt.

  See Also:
    `ConfigurableBeanFactory.addPropertyEditorRegistrar(org.springframework.beans.PropertyEditorRegistrar)`

### setCustomEditors

    public void setCustomEditors(Map<String,?> customEditors)

  Specify the custom editors to register via a `Map`, using the class name of the required type as the key and the class name of the associated `PropertyEditor` as value.

  Also supports `PropertyEditor` instances as values; however, this is deprecated since Spring 2.0.7!

  See Also:
    `ConfigurableBeanFactory.registerCustomEditor(java.lang.Class<?>, java.lang.Class<? extends java.beans.PropertyEditor>)`

### setIgnoreUnresolvableEditors

    public void setIgnoreUnresolvableEditors(boolean ignoreUnresolvableEditors)

  Set whether unresolvable editors should simply be skipped. Default is to raise an exception in such a case.

  This typically applies to either the editor class or the required type class not being found in the classpath. If you expect this to happen in some deployments and prefer to simply ignore the affected editors, then switch this flag to "true".

### setBeanClassLoader

    public void setBeanClassLoader(ClassLoader beanClassLoader)

  Description copied from interface: `BeanClassLoaderAware`
  Callback that supplies the bean `class loader` to a bean instance.

  Invoked after the population of normal bean properties but before an initialization callback such as `InitializingBean's` `InitializingBean.afterPropertiesSet()` method or a custom init-method.

  Specified by:
    `setBeanClassLoader` in interface `BeanClassLoaderAware`
  Parameters:
    `beanClassLoader` - the owning class loader; may be `null` in which case a default `ClassLoader` must be used, for example the `ClassLoader` obtained via `ClassUtils.getDefaultClassLoader()`

### postProcessBeanFactory

    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory)
                                throws BeansException

  Description copied from interface: `BeanFactoryPostProcessor`
  Modify the application context's internal bean factory after its standard initialization. All bean definitions will have been loaded, but no beans will have been instantiated yet. This allows for overriding or adding properties even to eager-initializing beans.

  Specified by:
    `postProcessBeanFactory` in interface `BeanFactoryPostProcessor`
  Parameters:
    `beanFactory` - the bean factory used by the application context
  Throws:
    `BeansException` - in case of errors
