这是我的`DAO

    import org.hibernate.transform.Transformers;

    import com.googlecode.s2hibernate.struts2.plugin.annotations.SessionTarget;
    import com.googlecode.s2hibernate.struts2.plugin.annotations.TransactionTarget;

    public class LeaveDAO {

        @SessionTarget

            } catch (Exception e) {
                e.printStackTrace();
            }

            return "SUCCESS";
        }

        public List<LeavePojo> retrieveData() {

        return"success";


        }*/}



service

    package com.sheeba;

import java.util.ArrayList;


import java.util.List;

import com.opensymphony.xwork2.ActionSupport;

import com.opensymphony.xwork2.ModelDriven;

import com.sheeba.*;

import org.apache.struts2.convention.annotation.InterceptorRef;
import org.apache.struts2.convention.annotation.ParentPackage;

@ParentPackage("hibernate-default")

public class LeaveService implements ModelDriven {
    LeavePojo modobj = new LeavePojo();
    LeaveDAO leaveDAO=new LeaveDAO();
    //private LeaveDAO leaveDAO;                                   // this is the dependency injection

    public LeaveDAO getLeaveDAO() {
        return leaveDAO;
    }

    public void setLeaveDAO(LeaveDAO leaveDAO) {
        this.leaveDAO = leaveDAO;
    }


    public List<LeavePojo> myList = new ArrayList<LeavePojo>();

    public List<LeavePojo> getMyList() {
        return myList;
    }

    public void setMyList(List<LeavePojo> myList) {
        this.myList = myList;
    }

    public List<LeavePojo> saveDetailsService(LeavePojo modobj) {

        System.out.println("inside savedetails service");
        leaveDAO.saveToDb(modobj);
        myList = leaveDAO.retrieveData();

        return myList;

    }



    @Override
    public Object getModel() {

        return modobj;
    }


}

这是行动

package com.sheeba;

import java.util.ArrayList;
import java.util.List;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.sun.org.apache.bcel.internal.generic.NEW;

public class LeaveAction extends ActionSupport implements ModelDriven<LeavePojo> {
    LeaveService ls=new LeaveService();
    LeavePojo pojo =new LeavePojo();
    public List<LeavePojo> myList = new ArrayList<LeavePojo>();

    public List<LeavePojo> getMyList() {
        return myList;
    }

    public void setMyList(List<LeavePojo> myList) {
        this.myList = myList;
    }
    private String bank_id;
    private String emp_name;
    private String leaves_applied;

    public String getBank_id() {
        return bank_id;
    }

    public void setBank_id(String bank_id) {
        this.bank_id = bank_id;
    }

    public String getEmp_name() {
        return emp_name;
    }

    public void setEmp_name(String emp_name) {
        this.emp_name = emp_name;
    }

    public String getLeaves_applied() {
        return leaves_applied;
    }

    public void setLeaves_applied(String leaves_applied) {
        this.leaves_applied = leaves_applied;
    }

    public String getServiceLasyer(){
        try{
        System.out.println(pojo.getBank_id()+"is bank id");
         myList=ls.saveDetailsService(pojo);
        }catch(Exception e){
            e.printStackTrace();
        }
        return SUCCESS;

    }

    @Override
    public LeavePojo getModel() {
        // TODO Auto-generated method stub
        return pojo;
    }



}

在这里使用过这些罐子/AAAAANEWPROJECT/WebContent/WEB-INF/lib/hibernate3.jar /AAAAANEWPROJECT/WebContent/WEB-INF/lib/hibernate-annotations-3.2.1.ga.jar /AAAAANEWPROJECT/WebContent/WEB-INF/lib/hibernate-core.jar /AAAAANEWPROJECT/WebContent/WEB-INF/lib/struts2-fullhibernatecore-plugin-2.2.2-GA.jar。对于休眠。

我无法获得输出。 404错误来了。罐子有问题吗？

Answer 1

我解决了！我从sourceforge DTD下载并将其添加到我的根目录，即SRC文件夹。并且，编辑了hibernate.cfg.xml，如下所示：

<!DOCTYPE hibernate-configuration SYSTEM  
"hibernate-configuration-3.0.dtd">

通过这种方式，应用程序不必点击URL，但它指向并在src文件夹中找到DTD。您可以在线使用系统时执行此操作。经过大量研究后，IT对我有用!!

使用Hibernate 3和Struts 2. cgf文件没有被读取。是因为JARS吗？
