Java 使用SpringMVC的缺陷跟踪WebApp

这是我的spring mvc web应用程序的登录屏幕。我需要捕捉每一个可能的错误条件，并存储到数据库中。比如bug检测系统

例如，如果用户单击“登录”按钮而不填写表单，则错误条件不应保存在错误表中

如果不提供密码，则应保存未提供的密码

@RequestMapping(value = { "/do-login" }, method = RequestMethod.POST)
    public String login(@ModelAttribute(value = "user") User user) {
        process(user);
        return "success";
    }

    public void process(User user) {

        List<User> users = userService.findAll();
        for (User u : users) {
            if (!u.getUserName().equals(user.getUserName())) {
                IssueDetail detail = new IssueDetail();
                detail.setSummary("user name");
                detail.setDescription("wrong user name entered");
                issueDetailService.save(detail);
            } else if (!u.getPassword().equals(user.getPassword())) {
                IssueDetail detail = new IssueDetail();
                detail.setSummary("password");
                detail.setDescription("wrong password entered");
                issueDetailService.save(detail);
            } else if (!u.getUserType().equalsIgnoreCase(user.getUserType())) {
                IssueDetail detail = new IssueDetail();
                detail.setSummary("user type");
                detail.setDescription("wrong user type entered");
                issueDetailService.save(detail);
            }
        }

    }

请尝试在代码行下面的流程方法内部代替for循环

                            List<User> users = userService.findAll();
            boolean isUserNameExist = false;
            boolean isPasswordExist = false;
            boolean isUserTypeExist = false;
            for (User u : users) {
                if (u.getUserName().equals(user.getUserName())) {
                    isUserNameExist = true;
                    break;
                } 
            }

            for (User u : users) {
               if (u.getPassword().equals(user.getPassword())) {
                    isPasswordExist =true;
                    break;
               } 
            }
            for (User u : users) {
                if (u.getUserType().equalsIgnoreCase(user.getUserType())) {
                    isUserTypeExist = true;
                    break;
                }
            }
            IssueDetail detail = new IssueDetail();
            if(!isUserNameExist){
                detail.setSummary("user name");
                detail.setDescription("wrong user name entered");
            }
            if(!isPasswordExist){
                detail.setSummary(detail.getSummary()+" password");
                detail.setDescription(detail.getDescription()+" wrong password entered");
            }
            if(!isUserTypeExist){
                detail.setSummary(detail.getSummary() +" user type");
                detail.setDescription(detail.getDescription() +" wrong user type entered");
            }
            issueDetailService.save(detail);

List users=userService.findAll（）；
布尔值isUserNameExist=false；
布尔值isPasswordExist=false；
布尔值isUserTypeExist=false；
for（用户u:用户）{
如果（u.getUserName（）.equals（user.getUserName（）））{
isUserNameExist=true；
打破
} 
}
for（用户u:用户）{
如果（u.getPassword（）.equals（user.getPassword（）））{
isPasswordExist=true；
打破
} 
}
for（用户u:用户）{
if（u.getUserType（）.equalsIgnoreCase（user.getUserType（）））{
isUserTypeExist=true；
打破
}
}
IssueDetail=新的IssueDetail（）；
如果（！isUserName存在）{
详细信息。设置摘要（“用户名”）；
detail.setDescription（“输入的用户名错误”）；
}
如果（！isPasswordExist）{
detail.setSummary（detail.getSummary（）+“密码”）；
detail.setDescription（detail.getDescription（）+“输入了错误的密码”）；
}
如果（！isUserTypeExist）{
detail.setSummary（detail.getSummary（）+“用户类型”）；
detail.setDescription（detail.getDescription（）+“输入了错误的用户类型”）；
}
IssuedDetailService.save（详细信息）；

那么你面临什么问题呢？代码有问题，它总是保存“输入的用户名错误”条件。升级后，条件添加不正确。你能提供你的测试用例吗？我是指你想要实现的输入和期望输出？更新了问题。让我们来看看。

                            List<User> users = userService.findAll();
            boolean isUserNameExist = false;
            boolean isPasswordExist = false;
            boolean isUserTypeExist = false;
            for (User u : users) {
                if (u.getUserName().equals(user.getUserName())) {
                    isUserNameExist = true;
                    break;
                } 
            }

            for (User u : users) {
               if (u.getPassword().equals(user.getPassword())) {
                    isPasswordExist =true;
                    break;
               } 
            }
            for (User u : users) {
                if (u.getUserType().equalsIgnoreCase(user.getUserType())) {
                    isUserTypeExist = true;
                    break;
                }
            }
            IssueDetail detail = new IssueDetail();
            if(!isUserNameExist){
                detail.setSummary("user name");
                detail.setDescription("wrong user name entered");
            }
            if(!isPasswordExist){
                detail.setSummary(detail.getSummary()+" password");
                detail.setDescription(detail.getDescription()+" wrong password entered");
            }
            if(!isUserTypeExist){
                detail.setSummary(detail.getSummary() +" user type");
                detail.setDescription(detail.getDescription() +" wrong user type entered");
            }
            issueDetailService.save(detail);
