我有一个类 NotifyBuilderUtil，我试图在其中创建另一个类 CustomEmailNotification 的对象。但是，在创建对象时，出现错误：
java.lang.NoSuchMethodError: net.mail.CustomEmailNotification: method <init>()V not found
package org.module.definition.notify;
...
import net.mail.CustomEmailNotification;
...
public class NotifyBuilderUtil implements InitializingBean {
private static NotifyBuilderUtil instance;
public NotifyBuilderUtil() {
if(instance != null) throw new SingletonViolationException(NotifyBuilderUtil.class);
instance = this;
}
...
...
public static void buildElements(DefinableEntity entity, Element item, Notify notifyDef, Writer writer, NotifyVisitor.WriterType writerType, Map params, boolean processItem) {
...
String flagElementPath = "./notify";
Element flagElem = (Element) nextItem.selectSingleNode(flagElementPath);
Map oArgs = DefinitionUtils.getOptionalArgs(flagElem);
NotifyVisitor visitor = new NotifyVisitor(entity, notifyDef, customItem, writer, writerType, params);
CustomEmailNotification cen = new CustomEmailNotification();
cen.constructInternalWriter(entity, visitor, flagElem, oArgs);
...
}
}
CustomEmailNotification ：
public class CustomEmailNotification {
private static Map timeFieldMap = null;
public static Writer internalWriter = null;
public static Writer externalWriter = null;
Writer writer;
public CustomEmailNotification() {
timeFieldMap = new HashMap();
}
...
public static void constructInternalWriter(DefinableEntity entity, NotifyVisitor visitor, Element flagElement, Map oArgs) {
...
...
}
}
错误信息是：
