我开始学习 spring，当我想向我的项目添加国际化时，我得到了这个错误。

我使用什么:

 1. Netbeans
 2. Maven 
 3. Spring 4.2.1
 4. Tomcat 8

这是我的项目结构: /image/jZ9xq.png

Servlet配置类

public class WebXmlConfiguration extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>[] getRootConfigClasses() {
    return new Class[]{};
}

@Override
protected Class<?>[] getServletConfigClasses() {
    return new Class[]{ApplicationConfiguration.class};
}

@Override
protected String[] getServletMappings() {
    return new String[]{"/"};
}
}

这是我的 spring 配置类

@Configuration
@ComponentScan("com.exercises.spring.springproject03")
@EnableWebMvc
public class ApplicationConfiguration extends WebMvcConfigurerAdapter {

@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 configureViewResolvers(ViewResolverRegistry registry) {
    registry.viewResolver(getInternalResourceViewResolver());
}


@Bean
public MessageSource getMessageSource() {
    ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    messageSource.setBasename("classpath:messages");
    return messageSource;
}

@Bean
public LocaleResolver getLocaleResolver() {
    SessionLocaleResolver resolver = new SessionLocaleResolver();
    resolver.setDefaultLocale(Locale.ENGLISH);
    return resolver;
}

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

}

@Override
public void addInterceptors(InterceptorRegistry registry) {
    LocaleChangeInterceptor interceptor = new LocaleChangeInterceptor();
    interceptor.setParamName("locale");
    registry.addInterceptor(interceptor);
}
}

它应该可以工作，但没有。有人可以帮助我吗？

最佳答案

解决方案

我花了很长时间才发现我的错误，但解决方案很简单。唯一要做的就是在消息源 bean 上添加 bean 名称。 

@Bean(name ="messageSource")
public MessageSource getMessageSource() {
    ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    messageSource.setBasename("classpath:messages");
    return messageSource;
}
