Question

我是春季验证的新手。我有一个带有4个文本字段的 loginform.html ，我试图验证它们但验证无法正常工作形成。但它接受我输入的每一个值。

例如：如果我输入了不正确的电子邮件，它应该会给我一个验证错误，例如“输入正确的电子邮件ID ”

loginform.java

public class loginform {
    @NotEmpty
    private String user;

    @NotEmpty
    @Email
    private String email;        

    @NotEmpty(message = "Phone should not be blank.")
    @Size(min = 10,max = 10)
    private String phone;

    @NotEmpty(message = "Enter your blog URL")
    @URL
    private String blog;
    // Get and set methods}

的login.html

<form:form action="login.html" commandName="userDetails">
<table>
<tr>
    <td><font face="verdana" size="2px">User</font></td>
    <td>:</td>
    <td>
    <font face="verdana" size="2">
    <form:input path="user" /> <form:errors path="user"></form:errors>
    </font>
    </td>
</tr>
<tr>
    <td><font face="verdana" size="2px">Email</font></td>
    <td>:</td>
    <td>
    <font face="verdana" size="2">
    <form:input path="email" /> <form:errors path="email"></form:errors>
    </font>
    </td>
</tr>
<tr>
    <td><font face="verdana" size="2px">Phone</font></td>
    <td>:</td>
    <td>
    <font face="verdana" size="2">
    <form:input path="phone" /> <form:errors path="phone"></form:errors>
    </font>
    </td>
</tr>
<tr>
    <td><font face="verdana" size="2px">Blog</font></td>
    <td>:</td>
    <td>
    <font face="verdana" size="2">
    <form:input path="blog" /> <form:errors path="blog"></form:errors>
    </font>
    </td>
</tr>
<tr>
    <td>
    <input type="submit" value="Submit" />
    </td>
</tr>
</table>
</form:form>

ContactController.java

@Controller
public class ContactController {

@RequestMapping(value = "/get", method = RequestMethod.GET)
public String get(ModelMap model) {
    loginform ud = new loginform();
     ud.setUser("prem");
     ud.setEmail("@gmail.com");
    model.addAttribute("userDetails",ud);
    return "login"; 
}

@RequestMapping("/login")
public String loginCheck(@Valid loginform userDetails, BindingResult result, ModelMap model) {

    if (result.hasErrors()) {
        return "login";
    } else {
        model.addAttribute("lfobj", userDetails);
        return "success";
    }
}

弹簧servlet.xml中

<context:annotation-config />
<context:component-scan base-package="net.viralpatel.spring3.controller" /> 

<bean id="jspViewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/jsp/" />
    <property name="suffix" value=".jsp" />
</bean>

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
   <property name="basename" value="props" />
</bean>

success.html

<body>
<font face="verdana" size="2">Welcome Mr. <b>${lfobj.user}</b>,<br>
Validations Success..!<br><br>
<u>You Entered</u><br>
</font>

<table>
    <tr><td>Email</td><td>${lfobj.email}</td></tr>
    <tr><td>Phone</td><td>${lfobj.phone}</td></tr>
    <tr><td>Website</td><td>${lfobj.blog}</td></tr>
</table>
</body>

props.properties

NotEmpty.userDetails.user = User Name is required
NotEmpty.userDetails.email = Email is required

Email.userDetails.email = Enter valid email Id
URL.userDetails.email = Enter valid URL

输出：运行时:( loginform.html - 获取输入）

*User :  sriprem 
Email :  sri 
Phone :  1323sri 
Blog :   nice*

它向我展示了我的“props.properties”文件中的错误，但它并没有直接显示我的所有输入!!

Success.html

Welcome Mr. sriprem,
Validations Success..!

You Entered
Email   prem 
Phone   1234sri 
Website nice

在上面的场景中，一切都是错误的格式，但它接受了数据！任何人都可以告诉我我的验证有什么问题。

按照弹簧文档：

http://docs.spring.io/spring/docs/3.0.0.RC3/reference/html/ch05s07.html

您是否配置了Bean验证实施？看一下 5.7.3配置DataBinder

Spring MVC验证不起作用
