这是我的 struts 文件，其中映射了所有操作文件 struts.xml
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="default" extends="struts-default">
<action name="AddTaskAction" class="actions.AddTaskAction" method="post">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
<action name="UpdateTaskAction"
class="actions.UpdateTaskAction" method="post">

这是 Action 类文件，我在这里写了关于使用 hibernates 事务、会话将数据插入数据库的内容 AddTaskAction.java
package actions;
import org.hibernate.Session;
import org.hibernate.Transaction;
import com.opensymphony.xwork2.ActionSupport;
import helper.FactoryProvider;
import model.Task;
public class AddTaskAction extends ActionSupport {
private Task t = new Task();
public String post() {
Session session = FactoryProvider.getFactory().openSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
session.persist(t);
tx.commit();
addActionMessage("Task added successfully!");
return SUCCESS;
} catch (Exception e) {
if (tx != null && tx.isActive()) {
tx.rollback();
}
addActionError("Error adding task: " + e.getMessage());
return ERROR;
} finally {
session.close();
}
}
public Task getT() {
return t;
}
public void setT(Task t) {
this.t = t;
}
}
In this below jsp page i written a code to take the data from the user and it will redirect the data into my action file to insert into databse
addTask.jsp

我正在尝试使用 struts2 将数据插入数据库，但结果我经常遇到上述错误
应该配置
input<action name="AddTaskAction" class="actions.AddTaskAction" method="post">
<result name="success">/success.jsp</result>
<result name="input">/addTask.jsp</result>
<result name="error">/error.jsp</result>
</action>
