spring - Spring CookieLocaleResolver：设置 cookiePath

Question

是否可以设置cookiePath应用程序名称的值（自动）？例如，我有一个 test.war，所以它可以在 bla.com/test/ 上使用，所以我希望我的 cookie 的路径是/test/而不是/默认值。谢谢

Answer 1

创建时，CookieLocaleResolver您可以设置path，但它将被硬编码。

前任

<bean id="localeResolver" class="CookieLocaleResolver">
    <property name="cookiePath" value="test" />
</bean>

另一种可能的解决方案是覆盖 LocaleResolver

public class MyCookieLocaleResolver extends CookieLocaleResolver {

    @Override
    public void setLocale(HttpServletRequest request,
            HttpServletResponse response, Locale locale) {
        if (locale != null) {
            // Set request attribute and add cookie.
            request.setAttribute(LOCALE_REQUEST_ATTRIBUTE_NAME, locale);
            addCookie(response, locale.toString());
        } else {
            // Set request attribute to fallback locale and remove cookie.
            request.setAttribute(LOCALE_REQUEST_ATTRIBUTE_NAME,
                    determineDefaultLocale(request));
            removeCookie(response);
        }
    }

    public void addCookie(HttpServletRequest request,
            HttpServletResponse response, String cookieValue) {
        Cookie cookie = createCookie(request, cookieValue);
        Integer maxAge = getCookieMaxAge();
        if (maxAge != null) {
            cookie.setMaxAge(maxAge);
        }
        if (isCookieSecure()) {
            cookie.setSecure(true);
        }
        response.addCookie(cookie);
        if (logger.isDebugEnabled()) {
            logger.debug("Added cookie with name [" + getCookieName()
                    + "] and value [" + cookieValue + "]");
        }
    }

    protected Cookie createCookie(HttpServletRequest request, String cookieValue) {
        Cookie cookie = new Cookie(getCookieName(), cookieValue);
        if (getCookieDomain() != null) {
            cookie.setDomain(getCookieDomain());
        }
        cookie.setPath(request.getContextPath());
        return cookie;
    }
}

如果使用 ServletContainer >= 2.5 和 spring 注解，则可以使用以下代码获取 ContextPath，因此您不必硬编码：

@EnableWebMvc
@Configuration
@ComponentScan("com.controller")
public class WebConfig extends WebMvcConfigurerAdapter {

    @Autowired
    private ServletContext servletContext;

    @Bean
    public LocaleResolver localeResolver(){
        CookieLocaleResolver resolver = new CookieLocaleResolver();
        resolver.setDefaultLocale(new Locale("en"));
        resolver.setCookieName("locale");
        resolver.setCookiePath(servletContext.getContextPath());
        resolver.setCookieMaxAge(31536000);
        return resolver;
    }

}
