Question

我正在学习Spring 3并尝试使用课程org.hibernate.validator.constraints.NotEmpty验证表单。

例如，我可以覆盖@Size消息（javax.validation.constraints.Size）和@Email消息（org.hibernate.validator.constraints.Email）从.properties文件中检索消息。

但我无法覆盖org.hibernate.validator.constraints.NotEmpty默认消息。我总是得到默认消息＆＃34;可能不是空的＆＃34;

这是我的XXXX-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

        </bean>
    </mvc:interceptors> 

    <context:component-scan base-package="com.springgestioneerrori.controller" />     

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

    <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">

    <bean id="localeChangeInterceptor"
        class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName" value="lang" />
    </bean>

    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" >

    </bean>

    <bean id="handlerMapping"
        class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
        <property name="interceptors">
            <ref bean="localeChangeInterceptor" />
        </property>
    </bean>

</beans>

这是我的用户类

package com.springgestioneerrori.model;    


import javax.validation.constraints.Size;   
import org.hibernate.validator.constraints.NotEmpty;

public class Utente {


    @NotEmpty 
    @Size(min=3,max=20)
    private String nome;            

    public String getNome() {
        return nome;
    }
    public void setNome(String nome) {
        this.nome = nome;
    }   

}

这是我的表格

.......
<form:form action="formSent" method="post" commandName="utente">
<form:errors path="*" cssClass="errorblock" element="div" /><br/><br/>
<spring:message code="form.label.utente.nome"/><form:input path="nome"/><form:errors path="nome" cssClass="error" /><br>  
<input type="submit">
</form:form>
 ......

这是我的控制者

........
    @RequestMapping("/formSent")
    public String formSent(Model model, @Valid Utente utente, BindingResult result){    

        if(result.hasErrors()){
            model.addAttribute("utente", utente);   
            return "form";
        }
        else{
            model.addAttribute("msg", "inserimento effettuato con successo");
            return "formSent";
        }       
    }
.........

这是我的属性文件

    NotEmpy.utente.nome = il campo nome non può essere vuoto //Im NOT able to get this message
    Size.utente.nome = Il nome deve contenere tra 2 e 30 lettere //Im able to get this message

Answer 1

您必须创建一个文件ValidationMessages.properties并将其放在应用程序的类路径中。 Hibernate验证器使用org.hibernate.validator.constraints.NotEmpty.message密钥来翻译消息

org.hibernate.validator.constraints.NotEmpty.message=il campo nome non può essere vuoto

<强>更新

要自定义单个邮件，请使用以下内容：

@NotEmpty( message = "{NotEmpy.utente.nome}" )
@Size(min=3,max=20, message = "{Size.utente.nome}")
private String nome;

Answer 2

试试这个 -

@NotEmpty（message =＆＃34; {NotEmpy.utente.nome}＆＃34;） private String nome;

Answer 3

感谢您的帮助。我犯了一个非常愚蠢的错误。在属性文件中，我写了NotEmpy而不是NotEmpty。对不起，给你留个时间:)）

我不能用.properties“覆盖”@NotEmpty消息
