Spring CookieLocalerResolver：设置cookiePath

是否可以使用应用程序名称的值（自动）设置

cookiePath

？ 例如，我有一个test.war，因此它将在bla.com/test/上可用，因此我希望我的cookie的路径是

/test/

，而不是

/

，这是默认值。

谢谢

当您创建

CookieLocalerResolver

时，您可以设置

路径

，但它将是硬编码的

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

@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;
    }

}

这就是为什么我会问（是否可以自动执行此操作）

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;
    }
}

@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;
    }

}
