使用thymeleaf的html表单验证无法在Spring Boot
我无法使用thymleaf模板以html形式捕获任何验证。
表单对象-
public class TestForm {....
@Pattern(regexp = "[a-zA-Z]*", message = "Only characters")
private String field1;
....
getter/setters
}
html代码-
<div id="main"> <form action="#" th:action="@{/create}" th:object="${testForm}" method="post" >
<div>
<label> Field1:</label>
<input type="text" th:field="${testForm.field1}" name="field1" />
<div th:if="${#fields.hasErrors('field1')}" th:errors="*{field1}">errors</div>
</div>
<input type="submit" value="Submit" />
</form>
</div>
控制器-
@RequestMapping(method= RequestMethod.POST, value = "/create")public String createTest(@Valid @ModelAttribute("testForm") TestForm testForm, MultipartHttpServletRequest request, BindingResult bindingResult) throws IOException {
if (bindingResult.hasErrors())
return "createtestform";
不会引发任何错误,并且表单已成功提交。
回答:
我觉得很麻烦,因为您放置BindingResult不正确。用MultipartHttpServletRequest替换它,它必须 验证参数之后:
@RequestMapping(method= RequestMethod.POST, value = "/create")public String createTest(@Valid @ModelAttribute("testForm") TestForm testForm, BindingResult bindingResult, MultipartHttpServletRequest request) throws IOException {
if (bindingResult.hasErrors())
return "createtestform";
