春天多语言

我刚接触Spring MVC,我在应用程序中添加多语言时遇到了一些问题。

我不'使用xml配置。我有一个@Configuration类

import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.HandlerMapping;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.handler.SimpleUrlHandlerMapping;
import org.springframework.web.servlet.i18n.CookieLocaleResolver;
import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;
import org.springframework.web.servlet.i18n.SessionLocaleResolver;
import org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages="com.springexamples.basic.controller")
public class BasicServletConfig extends BaseConfig {

    @Bean
    ViewResolver viewResolver() {
        return getViewResolver("views/basic/", ".jsp");
    }

    @Bean
    MessageSource messageSource() {
        return getMessageSource("/messages/messages");
}

@Bean
LocaleChangeInterceptor localeChangeInterceptor() {
    LocaleChangeInterceptor interceptor = new LocaleChangeInterceptor();
    interceptor.setParamName("lang");
    return interceptor;
}

@Bean
LocaleResolver localeResolver() {
    return new SessionLocaleResolver();
}

@Bean
HandlerMapping handlerMapping() {
    SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping();
    mapping.setInterceptors(new HandlerInterceptor[] { localeChangeInterceptor() });
    return mapping;
}
}

当我测试de应用程序总是看到默认语言(西班牙语)。我使用参数'lang = en'或'lang = EN'发送请求,但我仍然以默认语言看到它。

¿任何人都知道解决方案吗?。

谢谢,

我不确定HandlerMapping如何宣布这种方式会与@EnableWebMvc一起发挥作用。使用@EnableWebMvc配置拦截器的更惯用的方法是使用WebMvcConfigurer

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages="com.springexamples.basic.controller") 
public class BasicServletConfig extends BaseConfig implements WebMvcConfigurer {
    ...
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localeChangeInterceptor());
    }
    ...
}
