我正在尝试执行一个 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。但点击其他语言时，它也仅显示英语内容。请帮我找出我在这个程序中犯了什么错误。

public class InternationalizationDemoController {
@RequestMapping(value="/login.html")

ModelAndView modelView = new ModelAndView("Login");
modelView.addObject("headerMsg", "Please enter below details to login");
System.out.println("Inside InternationalizationDemoController..");
return modelView;

登录.jsp:

<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。
最佳答案
您需要更改<mvc:mapping path="/init" />至<mvc:mapping path="/**" /> .
