Question

我正在尝试在我的spring应用程序中构建一个功能，该功能将本地语言更改为切换语言。我以为我的逻辑是对的，但我猜不是。当我点击设置区域设置按钮时，它提示我为404

用户将在JSP中选择一个按钮，如Allbeers.jsp

所示。

   <form action="setLocale">
        <select name="locale">
            <option value="en"><spring:message code="lang.english"/></option>
            <option value="es"><spring:message code="lang.spanish"/></option>

        </select>
        <input type="submit" value="<spring:message code="button.setLocale"/>"/>
    </form>

form行为会将您带到控制器beerController.java

@RequestMapping(value = "setLocale", method = RequestMethod.GET)
public ModelAndView SetLocale(@RequestParam("locale") String locale, HttpServletRequest request, HttpServletResponse response) 
{
    LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(request);
    localeResolver.setLocale(request, response, StringUtils.parseLocaleString(locale));
    return new ModelAndView("redirect:/beer");
}

我的config.xml中的我的bean localeResolver

 <bean id="localeResolver"
          class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
    <property name="defaultLocale" value="en_IE" />
</bean>

这是我所有的控制器代码，以防需要知道如何映射方法

@Controller
@RequestMapping("/beer")
@SessionAttributes("beer")
public class beerController {

      @Autowired
    beerService service;

    @RequestMapping("")
    public ModelAndView getBeers() {
        //int x = Integer.parseInt("abc");
        return new ModelAndView("/Allbeers", "beerList", service.getAllBeers());
    }
@RequestMapping(value = "setLocale", method = RequestMethod.GET)
    public ModelAndView SetLocale(@RequestParam("locale") String locale, HttpServletRequest request, HttpServletResponse response) 
    {
        LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(request);
        localeResolver.setLocale(request, response, StringUtils.parseLocaleString(locale));
        return new ModelAndView("redirect:/beer");
    }

jsp中的form操作没有正确的路径

 <form action="/Assignment3/beer/setLocale">
        <select name="locale">
            <option value="en"><spring:message code="lang.english"/></option>
            <option value="es"><spring:message code="lang.spanish"/></option>

        </select>
        <input type="submit" value="<spring:message code="button.setLocale"/>"/>
    </form>

更改语言环境操作导致404
