我创建了一个 portlet，生成了.jarof 服务并将其移动到/tomcat/lib/ext. 然后我创建了一个使用相同 BD 的钩子。但是当我尝试在钩子中执行“DynamicQuery”时它不起作用，然后我尝试在 中创建一个新函数RuleLocalServiceImpl.java，再次生成.jar并将其移动到/tomcat/lib/ext. 但它不起作用，当我尝试执行时出现此错误：
java.lang.NoSuchMethodError: com.segmentationPortlet.service.RuleLocalServiceUtil.getActiveRule(Ljava/util/Date;)Ljava/util/List;
这是函数的解码代码：
public class RuleLocalServiceImpl extends RuleLocalServiceBaseImpl {
/*
* NOTE FOR DEVELOPERS:
*
* Never reference this interface directly. Always use {@link com.segmentationPortlet.service.RuleLocalServiceUtil} to access the rule local service.
*/
public List<Rule> getActiveRule(Date lastLogin) throws SystemException {
DynamicQuery dq_rules = DynamicQueryFactoryUtil.forClass(Rule.class, PortalClassLoaderUtil.getClassLoader())
.add(PropertyFactoryUtil.forName("modifiedDate").ge(lastLogin))
.add(PropertyFactoryUtil.forName("status").eq(true));
List<Rule> listRules = RuleLocalServiceUtil.dynamicQuery(dq_rules);
return listRules;
}
}
我尝试停止 tomcat，删除 .jar 并再次创建，但不起作用。
这是钩子的代码：

System.out.println("Login");
User user;
try {
user = PortalUtil.getUser(req);
Date lastLogin = user.getLastLoginDate();
List<Rule> listRule = RuleLocalServiceUtil.getActiveRule(lastLogin);
System.out.println("Size " + listRule.size());
} catch (PortalException e) {
