我是Spring的新手
我也在stackoverflow中搜索过web和相关帖子.我找不到我真正需要的那个.
我的目标是在重定向期间将模型属性从控制器传递到jsp页面,并避免在URL中显示属性.
以下是使用jdo验证从数据存储区登录.

我的控制器:

@Controller
public class LoginController {
    int count;
    PersistenceManager pm = PMF.get().getPersistenceManager();

    //Instance of data class
        User user;
    ModelAndView modelAndView=new ModelAndView();

    @RequestMapping(value="/Login",method = RequestMethod.POST)
    public ModelAndView loginValidate(HttpServletRequest req){

        //Getting login values
        String uname=req.getParameter("nameLogin");
        String pswd1=req.getParameter("pswdLogin");
        count=0;


        user=new User();

        //Generating Query
        Query q = pm.newQuery(User.class);
        q.setFilter("userName == userNameParam");
        q.declareParameters("String userNameParam");

        try{
            List<User> results = (List<User>) q.execute(uname);  
            for (User u: results) {

                String userName=u.getUserName();

                if(userName.equals(uname)){

                    System.out.println(u.getPassword());

                    if(u.getPassword().equals(pswd1)){
                        count=count+1;
                        modelAndView.setViewName("redirect:welcome");
                        modelAndView.addObject("USERNAME",uname);
                        return modelAndView;

                    }
         //rest of the logic 
    } …

通过login.jsp我需要一些值,所以我转发请求到控制器后我想j_spring_security_check从控制器调度默认值.

我怎么做 ？

我在这个仓库中操纵一个开源项目.该文件bank.sql是mysql中数据库的模式.这是pom.xml:
