Question

我已经尝试了很多但是@Transactional仍然没有用。我已经审阅了很多，但我仍然没有找到任何正确的答案

我想在两个不同的表中插入相同的记录，并且无所不能。意味着如果在一个表中插入数据时出现问题，则它必须从已插入的表中回滚。因此，对于任何问题，必须在两个表中插入或回滚数据。

请有人帮助我......

package com.cds.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;

import com.cds.service.SaveEmployeeService;
import com.cds.vo.EmployeeVo;


@Controller
public class SpringHibernateController {

    @Autowired
    SaveEmployeeService saveEmployeeService;

    @RequestMapping("home")
    public String showHomePage(){
        return "home";
    }

    @RequestMapping("form")
    public String showFormPage(){
        return "form";
    }

    @RequestMapping("submit")
    public String saveEmployeeFromData(@ModelAttribute("employee") EmployeeVo employeeVo,RedirectAttributes redirectAttributes){
        try{    
            saveEmployeeService.saveEmployeeAndCustomer(employeeVo);
            redirectAttributes.addFlashAttribute("success","Saved In Both Tables Successfully");
        }catch(Exception e){
            e.printStackTrace();
            redirectAttributes.addFlashAttribute("unsuccess","Unable To Save In Both Tables.. Please Try Again");
        }
        return "redirect:form";
    }

}

这是我的服务类，其中包含使用@Transactional在两个表中插入相同记录但不起作用的方法

@Service
public class SaveEmployeeServiceImpl implements SaveEmployeeService{

    @Autowired
    SaveEmployeeDAO saveEmployeeDAO;

    @Transactional(propagation=Propagation.REQUIRED)
    public void saveEmployeeAndCustomer(EmployeeVo employeeVo){
        int saveEmployee = saveEmployee(employeeVo);
        int saveCustomer = saveCustomer(employeeVo);
        if(saveEmployee==1 && saveCustomer==1){
            System.out.println("saved In both table successfully");
        }else{
            throw new RuntimeException();
        }
    }



    public int saveEmployee(EmployeeVo employeeVo) {
        Employee employee=null;
        try {
            employee=new Employee();
            employee.setName(employeeVo.getName());
            employee.setJobtitle(employeeVo.getJobtitle());
            employee.setSalary(Integer.parseInt(employeeVo.getSalary()));
            employee.setPassword(Integer.parseInt(employeeVo.getPassword()));
            employee.setPhoto(employeeVo.getPhoto().getBytes());
        } catch (IOException e) {
            e.printStackTrace();
        }
        return saveEmployeeDAO.saveEmployee(employee);
    }

    public int saveCustomer(EmployeeVo employeeVo) {
        int a=10/0;
        Customer cutomer=null;
        try {
            cutomer=new Customer();
            cutomer.setName(employeeVo.getName());
            cutomer.setJobtitle(employeeVo.getJobtitle());
            cutomer.setSalary(Integer.parseInt(employeeVo.getSalary()));
            cutomer.setPassword(Integer.parseInt(employeeVo.getPassword()));
            cutomer.setPhoto(employeeVo.getPhoto().getBytes());
        } catch (IOException e) {
            e.printStackTrace();
        }
        return saveEmployeeDAO.saveCustomer(cutomer);
    }
