Spring MVC and Error 400: SRVE0295E
提问by opad
I have problem with simple MVC application.
我对简单的 MVC 应用程序有问题。
dayoff.html
<div id="dayoff_operations" class="big_box_1">
<form:form modelAttribute="dayOff" enctype="multipart/form-data" action="/dayoff.html" >
<div style="width: 50%; float: left; margin-top: 0px ">
<form:label path="forDate" ><spring:message code="dayoff.fordate.label"/></form:label>
<form:input path="ax_forDate" id="datepicker" style="width:65px" readonly="readonly"/>
</div>
<div style="width: 50%; float: right; margin-top: 0px ">
<form:label path="toDate" ><spring:message code="dayoff.todate.label"/></form:label>
<form:input path="ax_toDate" id="datepicker2" style="width:65px" readonly="readonly" />
</div>
<div style="float: left">
<form:select cssClass="more" path="dayofftype" items="${dayoffTypes.list}" itemLabel="label" itemValue="value" htmlEscape="false" cssErrorClass="errorsField"/>
<form:errors path="dayofftype" cssClass="errors"/>
</div>
<input type="submit" name="add" value="Add"/>
</form:form>
Here is my controller:
这是我的控制器：
@Controller
@RequestMapping("/dayoff")
@SessionAttributes(types = {DayOff.class})
public class DaysOffController {
private Validator validator;
@Autowired
private ReloadableResourceBundleMessageSource messages;
@ModelAttribute("dayoffTypes")
public Map<String, Object> populateDayoffTypes(Locale locale) {
return Utils.createComboMap(DayoffType.values(), messages, locale);
}
@RequestMapping(method = RequestMethod.GET)
public String setupForm(Model model) {
model.addAttribute("dayOff", new DayOff());
model.addAttribute("cur_period",SessionManager.getCurrentPeriod());
return "dayoff";
}
@RequestMapping(method = RequestMethod.POST, params = "add")
public String addNewHoliday(@ModelAttribute DayOff dayOff, BindingResult result, ModelMap model) {
System.out.println("AAA");
return "/dayoff";
}
When I click Add button Error 400: SRVE0295E: Error reported: 400 appears, there is no information at server console. I assume it is realted to the setupForm() method which is displaying the form and crushing it to future submits. Can you please guide me with this?
当我单击添加按钮错误 400：SRVE0295E：错误报告：出现 400 时，服务器控制台上没有信息。我认为它与 setupForm() 方法有关，该方法显示表单并将其粉碎以供将来提交。你能指导我吗？

Error 400: SRVE0295E occurs also when MVC cannot fill @ModelAttribute Formwith values from HTML form.
错误 400：SRVE0295E 也会在 MVC 无法填充@ModelAttribute FormHTML 表单中的值时发生。
For example:
例如：
- class
Formhas primitive attributeint someCount - your HTML form has
<input>to assign value to this primitive attribute - user entered empty value (
null) to this<input>
- 类
Form具有原始属性int someCount - 你的 HTML 表单必须
<input>为这个原始属性赋值 - 用户
null为此输入了空值 ( )<input>
You should not use primitive types such as int, boolean, floatand so on.
你不应该使用原始的类型，例如int，boolean，float等等。

The return statements from setupForm and addNewHoliday are different. I presume you want to return the same view name from both. As you can see the form in order to submit it, I assume that the addNewHoliday return value of "/dayoff" should in fact be "dayoff"
setupForm 和 addNewHoliday 的返回语句是不同的。我想您想从两者中返回相同的视图名称。如您所见，为了提交表单，我假设“/dayoff”的 addNewHoliday 返回值实际上应该是“dayoff”
