Question

我正在通过书籍学习Spring MVC。所以当我输入此网址http://localhost:8080/webstore/market/products/add时。在浏览器上我收到一个错误。此外，我在此目录下有一个名为messages.properties的外部文件：/webstore/src/main/resources/messages.properties，其中包含以下内容：addProduct.form.productId.label =新产品ID。基本上，我正在尝试外化我的文件addProduct.jsp的标签。这是我的文件

@Configuration
@EnableWebMvc
@ComponentScan("com.packt.webstore")
public class WebApplicationContextConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Bean
    public InternalResourceViewResolver getInternalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setViewClass(JstlView.class);
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");

        return resolver;
    }

    @Override
    public void configurePathMatch(PathMatchConfigurer configurer) {
        UrlPathHelper urlPathHelper = new UrlPathHelper();
        urlPathHelper.setRemoveSemicolonContent(false);

        configurer.setUrlPathHelper(urlPathHelper);
    }

    // Added for -> Externalizing text messages
    @Bean
    public MessageSource messageResource() {
        ResourceBundleMessageSource resource = new ResourceBundleMessageSource();
        resource.setBasename("messages");
        resource.setDefaultEncoding("UTF-8");
        return resource;
    }
}

addProduct.jsp文件

浏览器出错：

message javax.servlet.ServletException：javax.servlet.jsp.JspTagException：在code＆＃39; addProduct.form.productId.label＆＃39;下找不到任何消息。对于语言环境＆＃39; ru_RU＆＃39;。

说明服务器遇到内部错误，导致无法完成此请求。
