我的Spring控制器和html有问题：单击提交按钮时没有绑定。
这是表格：
<form class="form-horizontal" role = "form" id="searchtodayeventsform">
<div class = "form-group">
<label for = "note" class = "col-sm-3 control-label">Date</label>
<div class = "col-sm-8">
<input type = "date" class = "form-control" id = "todaydatevalue" placeholder = "MM/DD/AAAA">
</div>
</div>
<div class = "form-group">
<label for = "type" class = "col-sm-3 control-label">OS</label>
<div class = "col-sm-8">
<select class = "form-control" id = "osnamevalue" name="todayostypeoptions">
<option value="Linux">Linux</option>
<option value="Windows">Windows</option>
</select>
</div>
</div>
<div class = "form-group">
<div class = "col-sm-offset-2 col-sm-10" id="submit">
<button type = "submit" class = "btn btn-default">Cerca</button>
</div>
</div>
这是用于控制日期参数并将所有内容发送到控制器的函数：
DTevents = $('#eventsosdatedata').DataTable(
{
"serverSide": true,
"ajax":{
url: "../geteventsosdate.json",
type: "post",
"data": function (d)
{
var param = {osnamevalue : $('#osnamevalue').val()};
if(moment($('#todaydatevalue').val()).isValid())
param = $.extend(param, {datevalue : moment($('#todaydatevalue').val()).toDate().getTime()});
console.log(param);
return $.extend(d, param);
}
},
这是控制器：
/**
* This method is used when a list of events of speficic day and os are requested
*
* @param model the model data
* @param request the http request
* @param os the os choosed
* @param date the date desired
* @return the updated model
* @throws IOException
*/
@PostMapping(value="/geteventsosdate.json")
@ResponseBody
public ModelAndView showEventsOsDate(ModelAndView model, HttpServletRequest request,
@RequestParam(name="osnamevalue", required=false) String os,
@RequestParam(name="todaydatevalue", required=false) Long date) throws IOException
{
Timestamp date_value;
Date effective_date = null;
if(date != null)
{
date_value = new Timestamp(date);
effective_date = new Date(date_value.getTime());
}
//First, we must populate the list of Events
List<Events> listEvents = networks.getEventsWithDateAndOs(os, effective_date);
//Second, we put this list in the model and set properties for jquery datatables
model.addObject("recordsTotal", listEvents.size());
model.addObject("recordsFiltered", listEvents.size());
model.addObject("data", listEvents);
//Finally, we return the model
return model;
}
在控制器内执行的查询是在这个DAO类方法中完成的：
/**
* Return the events with same format of the current day table,
* where users can choose day and os.
*
* @return a list with join query results
*/
public List<Events> getEventsWithDateAndOs(String os, Date date)
{
/**
* This is the string that contain the query to obtain the data from join of
* hosts and events with aggregator operations.
*/
String SQL = "SELECT hosts.name, hosts.os,"
+ " MAX(case when events.type = 'Applications' then events.status end) as Applications,"
+ " MAX(case when events.type = 'OS' then events.status end) as OS_Type,"
+ " MAX(case when events.type = 'Running Services' then events.status end) as Running_Services,"
+ " MAX(case when events.type = 'TCP Services' then events.status end) as TCP_Services,"
+ " MAX(case when events.type = 'File Integrity' then events.status end) as File_Integrity,"
+ " MAX(case when events.type = 'Services' then events.status end) as Services"
+ " FROM hosts JOIN events ON hosts.id = events.host_id"
+ " WHERE events.date = ? AND (? is null or hosts.os = ?)"
+ " GROUP BY hosts.name";
/**
* The list containing the results is obtained using the method query on jdcbtemplate, giving in in input to it the query string, the array of object
* containing the input variabile of the method and the rowmapper implemented.
*/
List<Events> theEvents = jdbcTemplate.query(SQL, new Object[]{os, os, date}, new EventTypeCountMapper());
return theEvents;
}
使用此rowmapper：
import java.sql.ResultSet;
import java.sql.SQLException;
import org.consorziotriveneto.networks.entity.Events;
import org.springframework.jdbc.core.RowMapper;
public class EventTypeCountMapper implements RowMapper<Events>
{
//This method must be implemented when we use a row mapper
public Events mapRow(ResultSet rs, int rowNum) throws SQLException
{
Events events = new Events();
//mapping of hosts attributes
events.setName(rs.getString("hosts.name"));
events.setOs(rs.getString("hosts.os"));
//mapping od count query
events.setApplications(rs.getString("Applications"));
events.setOs_type(rs.getString("OS_Type"));
events.setServices(rs.getString("Services"));
events.setRunning_services(rs.getString("Running_Services"));
events.setTcp_services(rs.getString("TCP_Services"));
events.setFile_integrity(rs.getString("File_Integrity"));
return events;
}
}
在控制台中执行应用程序我有：
Object { osnamevalue: undefined, datevalue: 1503646503530 }
未设置操作系统名称和当前日期的时间戳，而不是所选时间戳。
这不是我应用中的第一个表单绑定;我跟其他人一样遵循相同的架构，没有问题。我的印象是，我忘记了某些事情，某些特定的步骤，或者我做了一些错误的设置，但我无法理解。
答案 0 :(得分：0)
它没有进行绑定，因为未指定name参数。
请尝试这样：
<input type = "date" class = "form-control" id = "todaydatevalue" name"todaydatevalue" placeholder = "MM/DD/AAAA">
