Spring验证消息不插值

Question

我试图理解spring中的验证消息和国际化机制，并编写了以下代码：

public class Customer {

    @NotEmpty(message="{m1}")
    private String firstName;
    
    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

}

Bean配置：

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

<!--  Step 3: Add support for component scanning  -->
<context:component-scan base-package="com.example.demo"/>
<!--  Step 4: Add support for conversion, formatting and validation support  -->
<mvc:annotation-driven/>
<!--  Step 5: Define Spring MVC view resolver  -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/view/"/>
<property name="suffix" value=".jsp"/>
</bean>
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames" value="resources/messages"/>
</bean>
</beans>

资源文件系统结构：

-- resources
   messages.properties
   messages_it.properties

消息。属性：

m1=Not valid

messages\u it。属性：

m1=Non valido

当我提交表单时，得到的错误消息是：{m1}。我是否缺少一些代码？

Answer 1

缺少$是这里的问题@NotEmpty（message={m1}”）应该是@NotEmpty（message={m1}”）
