Java 为什么可以'；spring boot是否找到消息包？,java,spring,spring-boot,resourcebundle,Java,Spring,Spring Boot,Resourcebundle,我有一个非常简单的Spring启动应用程序，它似乎找不到消息包，它位于src/main/resources/i18n/messages\u pt\BR.properties 我的主要配置类是： @Configuration @EnableWebMvc @ComponentScan(basePackages = "b.c.g.application-name") public class ApplicationNameConfiguration { private static fina

我有一个非常简单的Spring启动应用程序，它似乎找不到消息包，它位于
src/main/resources/i18n/messages\u pt\BR.properties

我的主要配置类是：

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "b.c.g.application-name")
public class ApplicationNameConfiguration {

    private static final String MESSAGE_SOURCE = "/i18n/messages";
    private static final String HTML_VIEWS = "/WEB-INF/html/";

    private static final String RESOURCES_HANDLER = "/assets/";
    private static final String RESOURCES_LOCATION = RESOURCES_HANDLER + "**";

    @Bean
    @Description("Thymeleaf template resolver serving HTML 5")
    public ServletContextTemplateResolver templateResolver() {
        ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
        templateResolver.setCacheable(false);
        templateResolver.setTemplateMode("HTML5");
        templateResolver.setCharacterEncoding("UTF-8");
        templateResolver.setPrefix(HTML_VIEWS);
        templateResolver.setSuffix(".html");

        return templateResolver;
    }

    @Bean
    @Description("Thymeleaf template engine with Spring integration")
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.addDialect(new SpringSecurityDialect());
        templateEngine.addDialect(new LayoutDialect(new GroupingStrategy()));
        templateEngine.setTemplateResolver(templateResolver());

        return templateEngine;
    }

    @Bean
    @Description("Thymeleaf view resolver")
    public ViewResolver viewResolver() {

        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(templateEngine());
        viewResolver.setCharacterEncoding("UTF-8");
        viewResolver.setCache(false);
        viewResolver.setOrder(1);

        return viewResolver;
    }

    @Bean(name = "messageSource")
    @Description("Spring message resolver")
    public MessageSource messageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setBasename(MESSAGE_SOURCE);
        messageSource.setFallbackToSystemLocale(false);
        messageSource.setCacheSeconds(0);
        messageSource.setDefaultEncoding("utf-8");
        return messageSource;
    }

    @Bean(name = "localeResolver")
    @Description("Spring locale resolver")
    public LocaleResolver localeResolver() {
        SessionLocaleResolver resolver = new SessionLocaleResolver();
        resolver.setDefaultLocale(new Locale("pt", "BR"));
        return resolver;
    }

    @Bean(name = "multipartResolver")
    public StandardServletMultipartResolver resolver() {
        return new StandardServletMultipartResolver();
    }

    @Bean
    public UrlTemplateResolver urlTemplateResolver() {
        return new UrlTemplateResolver();
    }

    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler(RESOURCES_LOCATION).addResourceLocations(RESOURCES_HANDLER);
    }
}
尽管我主动声明locale为
pt\BR
，因此Spring应该在上述位置查找现有文件
messages\u pt\BR.properties
，但它失败并抛出：

在目前唯一的模板上，
login.html
，捆绑包的典型用法如下：

<div class="loginbox-textbox">
    <input type="text" id="ssoId" name="ssoId" class="form-control" th:placeholder="#{gen.username}" />
</div>
这里发生了什么？我该如何解决它？

您需要更改addResourceHandler和addResourceLocations，如下面和下面所示

            @Override  
            public void addResourceHandlers(ResourceHandlerRegistry registry) {  
                    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");  

            }
如果不起作用，还可以更改
messageSource.setBasename（“i18n/messages”）
您需要更改addResourceHandler和addResourceLocations，如下和


            @Override  
            public void addResourceHandlers(ResourceHandlerRegistry registry) {  
                    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");  

            }



如果不起作用，还可以更改
messageSource.setBasename（“i18n/messages”）
能否显示您如何在控制器或模板中使用区域设置？@ShawnClark，问题已更新以显示消息包。请在同一文件中创建名为messages.properties的空文件folder@Georgesvanhoutte,我仍然得到相同的错误…基于此示例：您不想在basename前面加上
/
，因此它应该是
i18n/messages
