基于 Spring MVC LocaleChangeInterceptor 注释不起作用

问题描述

import java.util.Locale;

import 免费vpn org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;
import org.springframework.web.servlet.HandlerMapping;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.i18n.CookieLocaleResolver;
import free vpn org.springframework.web.servlet.i18n.LocaleChangeInterceptor;
import org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping;

@Configuration
public class Config {
    @Bean
   免费vpn  vpn下载 public LocaleResolver localeResolver() {
        final CookieLocaleResolver ret = new CookieLocaleResolver();
        ret.setDefaultLocale(new Locale("en_US"));
        return ret;
    }

    @Bean
  vpn下载   public MessageSource messageSource() {
   免费vpn      final ReloadableResourceBundleMessageSource ret = new vpn下载 ReloadableResourceBundleMessageSource();
  免费vpn       ret.setBasename("classpath:lang");
        ret.setDefaultEncoding("UTF-8");
     免费vpn    return ret;
    }

    @Bean
    public HandlerMapping 免费vpn handlerMapping() free vpn {
   vpn下载      final LocaleChangeInterceptor interceptor = new LocaleChangeInterceptor();
     vpn下载    interceptor.setParamName("language");

     vpn free   vpn下载  final DefaultAnnotationHandlerMapping ret = new DefaultAnnotationHandlerMapping();
        ret.setInterceptors(new Object[] { interceptor });
      vpn下载   return ret;
    }
}

以上是我的注解配置.我基本上已经翻译了 this 教程的 免费vpn下载 XML.

The above is my annotation vpn free configuration. I've basically translated this tutorial's XML.

奇怪的是，当我转到 ...?language=fr 时它不起作用.

Strangely it doesn't work when I go to ...?language=fr.

但是，以下确实有效(在 vpn下载 app-servlet.xml 中)(注意这里使用的是 locale):

However, the following does work (in app-servlet.xml) (notice here it's using locale):

<mvc:interceptors>
  free vpn  免费vpn  <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
  vpn free 免费vpn下载       free vpn <property name="paramName" value="locale" />
    </bean>
</mvc:interceptors>

另一个需要注意的重要事情是，当我在上述方法上设置断点时，所有这三个方法，每个断点都会中断，这意味着某人"正在读取这些值.

Another important thing to note is that when 免费vpn I put breakpoints on the above methods, all of the three of them, every breakpoint does break, which implies that "someone" is reading the values.

那么，为什么我的基于注释的拦截器不起作用?

So, why wouldn't my annotation based interceptor doesn't work?

推荐答案

通过 WebMvcConfigurerAdapter 扩展配置类可能会有所帮助.添加拦截器条目覆盖

Extending config class by WebMvcConfigurerAdapter may help. to add interceptor 免费vpn entry override

public void addInterceptors(InterceptorRegistry registry) {
   registry.addInterceptor(localeChangeInterceptor());
} 

方法.还为 LocaleChangeInterceptor

@Bean 
public LocaleChangeInterceptor localeChangeInterceptor(){
    LocaleChangeInterceptor localeChangeInterceptor=new LocaleChangeInterceptor();
 免费vpn下载    localeChangeInterceptor.setParamName("language");
    return localeChangeInterceptor;
}
