我正在使用 spring 3.2.3、servlet 3 和 maven 3.1，所以我正在尝试使用 i18n，但由于某些黑暗的原因，我无法启动我的应用程序说：
javax.servlet.ServletException: javax.servlet.jsp.JspTagException: No message found under code 'login.button.signin' for locale 'pt_BR'.
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:912)
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:841)
但我的默认语言是“EN”，我有这两个属性的消息。
代码：
WebConfig.java
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "com.codesenior.oaon.controller" })
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
localeChangeInterceptor.setParamName("lang");
registry.addInterceptor(localeChangeInterceptor);
}
@Bean
public LocaleResolver localeResolver() {
CookieLocaleResolver cookieLocaleResolver = new CookieLocaleResolver();
cookieLocaleResolver.setDefaultLocale(StringUtils.parseLocaleString("en"));
return cookieLocaleResolver;
}
@Bean
public MessageSource messageSource() {
ReloadableResourceBundleMessageSource source = new ReloadableResourceBundleMessageSource();
source.setBasename("classpath:messages");
source.setDefaultEncoding("UTF-8");
return source;
}
@Bean
public InternalResourceViewResolver templateResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/pages/");
resolver.setSuffix(".jsp");
resolver.setCache(false);
return resolver;
}
索引.jsp

消息（当前路径：src/main/resources）
messages_en.properties
login.label.username=Username
login.label.password=Password
login.button.signin=Signin
messages_pt.properties
login.label.username=Usuário
login.label.password=Senha
login.button.signin=Entrar
由于我的默认语言是 EN，我不知道它为什么要求 PT，尽管即使我忽略了这一点，我也有包含正确消息的 messages_pt.properties。
