java - 我不能使用 .properties "override"@NotEmpty 消息

Question

我正在学习 Spring 3，我正在尝试使用 org.hibernate.validator.constraints.NotEmpty 类来验证表单。

例如，我能够覆盖 @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。我总是收到默认消息“可能不为空”

这是我的 XXXX-servlet.xml

        </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 Controller

........
    @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 validator 使用 org.hibernate.validator.constraints.NotEmpty.message 键来翻译消息

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

在这里查看更多信息:

http://docs.jboss.org/hibernate/validator/4.3/reference/en-US/html/validator-usingvalidator.html#section-message-interpolation

更新

要自定义单个消息，请使用如下内容:

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