and exception every time try run client

org.springframework.beans.factory.beancreationexception: error creating bean     name 'org.springframework.beans.factory.config.customeditorconfigurer#0' defined in class path resource [beans.xml]:  initialization of bean failed; nested exception org.springframework.beans.typemismatchexception: failed convert property value of type 'java.util.linkedhashmap' required type 'java.util.map' property 'customeditors'; nested exception java.lang.illegalargumentexception: cannot convert value of type [org.springframework.beans.propertyeditors.customdateeditor] required type [java.lang.class] property 'customeditors[java.util.date]': propertyeditor [org.springframework.beans.propertyeditors.classeditor] returned inappropriate value of type [org.springframework.beans.propertyeditors.customdateeditor] 

note propertyeditor stateful, should not register instances directly.

• register property editor classes via customeditor property
• add propertyeditorregistrars via propertyeditorregistrars property in customeditorconfigurer

as want configure property editor instance, use property editor registrar instead.
