java - Spring + hibernate : manually commit the transaction at end

Question

我正在使用 spring mvc 和 hibernate

@Controller
public class COACategoriesController {

protected static Logger log = Logger.getLogger(COACategoriesController.class);


@Resource(name="COACategoriesService")
private COACategoriesService obj_coacs;
@Resource(name="COAMaintenanceService")
private COAMaintenanceService obj_coams;

 @RequestMapping(value = "/addCoaCategory", method = RequestMethod.POST)
 public String addCoaCategory(@RequestParam("conCatName") String coaCatName, Model model) {

     Date sysdate = null;
     String Message="";
     try{

     sysdate = new Date();


     COACategoriesModel model1 = new COACategoriesModel( coaCatName, 1, "", sysdate , 0);

     COAMaintenanceModel account =  new COAMaintenanceModel();
        account.setDiscription("Test Description");
        account.setCategoryId(model1);

        Message="Fail-First";
        obj_coacs.AddCOACategories(model1);


        Message="Fail-Second";
        obj_coams.AddCOAMaintenance (account);


        Message="Add Successfully";
     }catch(Exception ex){
         log.error("Exception.."+ex);
         model.addAttribute("success", Message);
     }



        return "fin/category";
    }



}

当所有事务保存成功时，我如何手动提交事务，如果任何事务插入失败，则回滚catch block 中的所有事务。 ？

Answer 1

我更愿意在某些服务中创建一个单独的方法(结合您的 2 个方法)来处理那里的所有必要事务。
