我快疯了..几个小时以来我一直在寻找我的错误。
我的表单没有进入操作。但我检查了1000遍。一切都拼写正确。 我不知道... 请大家帮忙!
我心爱的错误消息:
HTTP Status 404 - No result defined for action de.nordakademie.librarymgmt.action.CreatePubAction and result input

这就是jsp。在名为 createPublication.jsp 的文件夹 jsp

最后但并非最不重要的行动:
package de.nordakademie.librarymgmt.action;
import com.opensymphony.xwork2.ActionSupport;
import de.nordakademie.librarymgmt.model.Publication;
import de.nordakademie.librarymgmt.service.IPublicationService;
public class CreatePubAction extends ActionSupport {
private static final long serialVersionUID = 1L;
private Publication publication;
private IPublicationService publicationService;
@Override
public String execute() throws Exception {
try{
publicationService.savePublication(publication);
return SUCCESS;
} catch(Exception e){
e.printStackTrace();
return ERROR;
}
}
public Publication getPublication() {
return publication;
}
public void setPublication(Publication publication) {
this.publication = publication;
}
public IPublicationService getPublicationService() {
return publicationService;
}
public void setPublicationService(IPublicationService publicationService) {
this.publicationService = publicationService;
}
}
最佳答案
您在日志中看到过堆栈跟踪吗？
我大胆猜测您的错误响应正在被调用，而您没有映射它。您可以尝试在图 block 配置中显式定义错误结果吗？
我最初的直觉(来自处理过一个非常相似的问题)是您的一个 JSP 文件要么在tiles配置中拼写错误，要么没有包含在Web应用程序中。我会仔细检查一下。
