Question

我正在尝试执行Spring MVC国际化演示程序，该程序将以三种不同的语言（即英语，意大利语和德语）在“登录”页面上显示用户名和密码。但是也单击其他语言，它仅以英语显示内容。请帮助我找出我在此程序中犯了什么错误。

        <url-pattern>/</url-pattern>
    </servlet-mapping>  

</web-app>

spring-dispatcher-servlet.xml：

    </bean>
</beans>

InternationalizationDemoController.java：

package com.demo.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class InternationalizationDemoController {

    @RequestMapping(value="/login.html")
    public ModelAndView getAdmissionForm(){
        ModelAndView modelView = new ModelAndView("Login");
        modelView.addObject("headerMsg", "Please enter below details to login");
        System.out.println("Inside InternationalizationDemoController..");
        return modelView;
    }

}

Login.jsp：

<!DOCTYPE html>
<html>
<head>
</head>
<body>

<%@ page contentType="text/html;charset=UTF-8"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

Select Language : <a href="?lang=en">English</a> | <a href="?lang=de">German</a> | <a href="?lang=it">Italian</a>

<form action="/FirstSpringMVCAnnotations/login.html">
  <div class="container">

    <h1 align="center">Login Page</h1>
    <p>${headerMsg}</p>
    <hr>

    <spring:message code="spring.username.label" />
    <input type="text" name="username"><br><br>

    <spring:message code="spring.password.label" />
    <input type="password" name="password"><br><br>

    <button type="submit" class="submitbtn">Submit</button>
    <button type="reset" class="resetbtn">Reset</button>
  </div>

</form>

</body>
</html>

我在/ Web-Inf文件夹中有message_en.properties，message_it.properties和message_de.properties文件。

message_en.properties

spring.username.label=User name
spring.password.label=Password

message_de.properties

spring.username.label=Nutzername
spring.password.label=Passwort

message_it.properties

spring.username.label=Nome utente
spring.password.label=Parola d'ordine

如下图所示，单击德语也会显示英语的用户名和密码标签。

Answer 1

You need to change <mvc:mapping path="/init" /> to <mvc:mapping path="/**" />.
