Question

我正在学习春天和百里香，并参与一个计时项目。为此，我需要验证员工在一天内计时的小时数。

我使用了tutorial in the spring documentation但是我一直收到以下错误

  @RequestMapping(value="Timetable/AddToTimetable", method = RequestMethod.GET)
public String newUser(Model md) {
    md.addAttribute("assignments", serv.findAll());
    return "AddToTimetable";
}

@RequestMapping(value = "/createEntry", method = RequestMethod.POST)
public String create(@RequestParam("assignmentId") int assignmentId,
                     @RequestParam("date") @DateTimeFormat(pattern = "yyyy-MM-dd") Date date,
                     @RequestParam("hoursWorked") int hoursWorked,
                     @Valid Timetable timetable, BindingResult bindingResult,
                     Model md) {
    timetable = new Timetable();
    timetable.setAssignmentId(assignmentId);
    timetable.setDate(date);
    timetable.setHoursWorked(hoursWorked);
    md.addAttribute("timetables", service.timetableAdd(timetable));
 if (bindingResult.hasErrors()) {
        return "AddToTimetable";
    }
    return "redirect:/Timetable";
}

任何想法我可能做错了什么？

控制器类

public BigInteger timetableAdd(Timetable timetable){
    KeyHolder keyHolder = new GeneratedKeyHolder();
    String sql = "INSERT INTO timetables ( assignmentId, date, hoursWorked) VALUES ( ?, ?, ?)";
    template.update(new PreparedStatementCreator() {
        public PreparedStatement createPreparedStatement(Connection con) throws SQLException {
            PreparedStatement pst = con.prepareStatement(sql, new String[] {"id"});

            pst.setInt(1, timetable.getAssignmentId());
            pst.setDate(2, new java.sql.Date(timetable.getDate().getTime()));
            pst.setInt(3, timetable.getHoursWorked());
            return pst;
        }
    }, keyHolder);
    return (BigInteger) keyHolder.getKey();
}
}

更新：

时间表（跳过bootstrap div）

    @Autowired
JdbcTemplate template;

public List<Timetable> findAll(String loginname) {
    String sql = "  SELECT timetables.timetableId, timetables.assignmentId, timetables.date, " +
            "timetables.hoursWorked, users.username, projects.projectName AS project " +
            "FROM timetables INNER join assignments on timetables.assignmentId = assignments.assignmentId " +
            "INNER JOIN projects on assignments.projectId = projects.projectId " +
            "INNER JOIN users on users.userId = assignments.userId where username= ?";

    RowMapper<Timetable> rm = new RowMapper<Timetable>() {
        @Override
        public Timetable mapRow(ResultSet resultSet, int i) throws SQLException {
            Timetable timetable = new Timetable(resultSet.getInt("timetableId"),
                    resultSet.getString("project"),
                    resultSet.getDate("date"),
                    resultSet.getInt("hoursWorked"));

            return timetable;
        }
    };

    return template.query(sql, rm, loginname);
}

时间表的服务方法

    @RequestMapping(value = {"/Timetable"}, method = RequestMethod.GET)
public String index(Model md){
    org.springframework.security.core.Authentication auth = SecurityContextHolder.getContext().getAuthentication();
    String loginname = auth.getName();
    md.addAttribute("timetables", service.findAll(loginname));
    return "Timetable";
}

时间表的控制器方法

for file in `ls img*.nc` ; do 
  ncks -d lat,17.52,30.98 -d lon,-98.52,-78.02 ${file} -O ${file%???}_cut.nc
done

Answer 1

如果我理解正确，你有两个html页面，一个显示所有的分配，一个你输入新的条目。我认为在新的输入页面中出现验证错误时会出现错误。

替换这些行

const handleResponse = (response) => {
  const { person: { user } = {} } = response || {};

  // since user is the value to be used you don't need to set a default unless you need it
  if (user) // do your stuff here
}

有这些

if (bindingResult.hasErrors()) {
   return "AddToTimetable";
}

如果出现错误，您应该转到您尝试输入新条目的页面，而不是转到包含所有作业的页面。
