我快疯了。我从几个小时开始就在寻找我的错误。
我的表单不会进入操作。但我检查了 1000 次。一切都拼写正确。我不知道。。。请帮忙！
我心爱的错误消息：
HTTP 状态 404 - 没有为操作定义结果 de.nordakademie.librarymgmt.action.CreatePubAction and result input
类型 状态报告
消息 未为操作定义结果 de.nordakademie.librarymgmt.action.CreatePubAction and result input
说明 请求的资源不可用。

这就是文件夹 jsp 中的 jsp，称为 createPublication.jsp

最后但并非最不重要的一点是动作：
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;
}
}
您是否在日志中看到堆栈跟踪？
我冒昧地猜测您的 ERROR 响应正在被调用，而您没有映射它。 您可以尝试在磁贴配置中显式定义错误结果吗？
我最初的直觉（从处理一个非常相似的问题开始）是你的一个JSP文件要么在瓷砖配置中拼写错误，要么没有包含在Web应用程序中。 我会仔细检查一下。
<action name="createPubAction"
class="de.nordakademie.librarymgmt.action.CreatePubAction">
<result type="tiles" name="success">catalog</result>
</action>
您只定义了success。错误说，操作正在返回input结果，正如您在上面看到的，如果遇到结果input没有定义该怎么做。
快速修复可以是：
<action name="createPubAction"
class="de.nordakademie.librarymgmt.action.CreatePubAction">
<result type="tiles" name="success">catalog</result>
<result type="tiles" name="input">catalog</result>
</action>
