Elb*_*bek 3 validation spring-mvc
我正在使用spring mvc 3.0.这是我的控制器类:
@Controller
@RequestMapping("/author")
public class AuthorController {
@Autowired
private IAuthorDao authorDao;
@InitBinder
public void initBinder(WebDataBinder binder) {
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
binder.registerCustomEditor(Date.class, new CustomDateEditor(
dateFormat, true));
}
@RequestMapping(method = RequestMethod.GET)
public String get(Model model) {
return "author-list";
}
@RequestMapping(value = "/new", method = RequestMethod.GET)
public String create(Model model) {
model.addAttribute("author", new Author());
return "author-form";
}
@RequestMapping(value = "/new", method = RequestMethod.POST)
public String createPost(@ModelAttribute("author") Author author,
BindingResult result) {
new AuthorValidator().validate(author, result);
if (result.hasErrors()) {
return "author-form";
} else {
authorDao.persist(author);
return "redirect:/author/" + author.getId();
}
}
@RequestMapping(value = "/{authorId}", method = RequestMethod.GET)
public String view(@PathVariable("authorId") int authorId) {
return "author-view";
}
}
我正在尝试验证作者对象.它有dob attr,类型是Date.
我正在使用以下类进行验证:
public class AuthorValidator {
public void validate(Author author, Errors errors) {
if(author.getfName()==null)
errors.rejectValue("fName", "required", "required");
else if (!StringUtils.hasLength(author.getfName())) {
errors.rejectValue("fName", "required", "required");
}
if(author.getfName()==null)
errors.rejectValue("lName", "required", "required");
else if (!StringUtils.hasLength(author.getlName())) {
errors.rejectValue("lName", "required", "required");
}
if(author.getDob()==null)
errors.rejectValue("dob", "required", "required");
else if (!StringUtils.hasLength(author.getDob().toString())) {
errors.rejectValue("dob", "required", "required");
}
}
}
当我没有在表单中输入任何内容时它会提供所需的消息,这是正确的,但是当我给出不正确的格式时,它会将写入Failed to convert property value of type java.lang.String to required type java.util.Date for property dob; nested exception is java.lang.IllegalArgumentException: Could not parse date: Unparseable date: "asdads"
required作为消息.如何使它像"无效的日期".
谢谢.
如果您使用标准的Spring设施,您需要做的就是:
添加messageSource:
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="com.example.messages" />
</bean>
添加com/example/messages.properties包含以下之一的属性文件:
typeMismatch.author.date = Invalid date
typeMismatch.date = Invalid date
typeMismatch.java.util.Date = Invalid date
typeMismatch = Invalid date
首先让你为特定的字段(date),特别是命令对象(author)配置错误消息,第二个 - date任何命令对象中的字段,第三个 - 用于绑定java.util.Date类字段的错误的消息,以及最后一个 - 错误的一般消息由任何转换产生.
这是我的JSP页面:
<%@ taglib uri="http://www.springframework.org/tags" prefix="s" %>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="sf" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
<sf:form commandName="author">
<sf:errors path="date" /><br />
<sf:input path="name"/><br />
<sf:input path="date"/><br />
<input type="submit" value="ok" />
</sf:form>
</body>
</html>
