Spring Security i18n:错误的错误消息已解决

我正在开发使用Spring(MVC),Hibernate,Spring Security和ZK作为前端的Web应用程序。我正在使用所有库的最新版本(3.1.2 Spring,3.1.3 Spring Security,4.1.7 Hibernate),我遇到了国际化问题(i18n)。我将在配置后进入细节(仅限相关部分):

servlet的上下文

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

<interceptors>
    <beans:bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <beans:property name="paramName" value="lang" />
    </beans:bean>
</interceptors>

<beans:bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <beans:property name="basename" value="classpath:message" />
</beans:bean>

弹簧security.xml文件:

<http pattern="/resources/**" security="none" />

<http auto-config="true">
    <intercept-url pattern="/login*" access="IS_AUTHENTICATED_ANONYMOUSLY" />
    <intercept-url pattern="/**" access="ROLE_USER" />
    <form-login login-page="/login" default-target-url="/" authentication-failure-url="/loginfailed" />
</http>

根context.xml中:

这里没有任何问题,只有数据源定义,sessionfactory和bean声明。

现在解决问题:

我有两个文件:message_en.properties和message_hr.properties,它们都位于src / main / resources目录中。我使用“Spring模板项目”创建了这个项目,然后选择了“Spring MVC项目”(使用STS 2.9.2)。我已经阅读了有关如何自定义Spring Security消息的信息,而那些需要被覆盖的消息放在message.properties文件中,并附带自定义消息。我用来测试的是:

spring-security-core.jar中的原始消息 AbstractUserDetailsAuthenticationProvider.badCredentials =错误凭据

在message_en.properties中重写:

AbstractUserDetailsAuthenticationProvider.badCredentials =无效的用户名或密码

在message_hr.properties中重写:

AbstractUserDetailsAuthenticationProvider.badCredentials = Bla Bla Bla

情景1:

如果我将上述所有内容保留在配置文件中,在url栏中更改lang参数,或者只需单击登录页面中的链接,就可以正确读取自定义message_xx.properties中的所有消息,但SS的除外。因此,我没有给我“无效的用户名或密码”或“Bla Bla Bla”,而是获得了“不良凭证”。

情景2:

如果我将messageSource bean从servlet-context.xml移动到spring-security.xml,它会加载正确的错误消息,但无论设置什么语言环境,它总是读取“Bla Bla Bla”。即使我更改了localeChangeInterceptor bean的lang参数,也会发生这种情况。

我想在这里做些什么来使这项工作正常进行?

忘记提及: 为了获得Spring Security消息,我在jsp页面中使用它

$ {sessionScope [ “SPRING_SECURITY_LAST_EXCEPTION”]。消息}

遇到同样的问题。阅读this from Spring Security i18n后,我创建了一个过滤器:

  1. 从cookie中检索语言环境(我正在使用CookieLocaleResolver但这可以使用其他类型的localeResolver来完成,例如SessionLocaleResolver)
  2. 并调用LocaleContextHolder.setLocale(locale,true)
  3. 在chain.doFilter之前。
  4. 此过滤器必须出现在spring.xml中的springSecurityFilterChain的过滤映射之前。这样,当spring-security调用LocaleContextHolder.getLocale()时,它会检索正确的。在您的情况下,您可以从会话中检索语言环境,因为您使用的是org.springframework.web.servlet.i18n.SessionLocaleResolver。

    在spring context xml文件中(你仍然可以使用SessionLocaleResolver):

        <!-- Saves a locale change using a cookie -->
    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" />
    

    Java过滤器代码(重要的一行是LocaleContextHolder.setLocale,因为spring-security使用了LocaleContextHolder.getLocale):

    package com.xyz;
    
    import java.io.IOException;
    import java.util.Locale;
    
    import javax.servlet.Filter;
    import javax.servlet.FilterChain;
    import javax.servlet.FilterConfig;
    import javax.servlet.ServletException;
    import javax.servlet.ServletRequest;
    import javax.servlet.ServletResponse;
    import javax.servlet.http.Cookie;
    import javax.servlet.http.HttpServletRequest;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.context.i18n.LocaleContextHolder;
    import org.springframework.web.servlet.i18n.CookieLocaleResolver;
    import org.springframework.web.util.WebUtils;
    
    /**
     * Transfert the value of user Locale into LocaleContextHolder which is used by spring-security
     */
    public class FilterI18nCookie implements Filter {
        private static final Logger LOG = LoggerFactory.getLogger(FiltreI18nCookie.class);
    
        /**
         * @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest,
         *      javax.servlet.ServletResponse, javax.servlet.FilterChain)
         */
        public void doFilter(ServletRequest pRequest, ServletResponse pResponse, FilterChain pFilterChain) throws IOException, ServletException {
            if (!(pRequest instanceof HttpServletRequest)) {
                pFilterChain.doFilter(pRequest, pResponse);
                return;
            }
    
            HttpServletRequest request = (HttpServletRequest) pRequest;
    
            Cookie cookie = WebUtils.getCookie(request, CookieLocaleResolver.LOCALE_REQUEST_ATTRIBUTE_NAME);
            if (cookie != null) {
                Locale locale = org.springframework.util.StringUtils.parseLocaleString(cookie.getValue());
                if (locale != null) {
                    LOG.info("Locale cookie: [" + cookie.getValue() + "] == '" + locale + "'");
                    request.setAttribute(CookieLocaleResolver.LOCALE_REQUEST_ATTRIBUTE_NAME, locale);
                    LocaleContextHolder.setLocale(locale, true);
                }
            }
    
            pFilterChain.doFilter(pRequest, pResponse);
        }
    
        /**
         * @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
         */
        public void init(FilterConfig filterConfig) throws ServletException {
        }
    
        /**
         * @see javax.servlet.Filter#destroy()
         */
        public void destroy() {
        }
    
    }
    

    在web.xml文件中(springSecurityFilterChain之前的自定义过滤器FilterI18nCookie appreas的过滤器映射定义):

    <filter>
        <filter-name>FilterI18nCookie</filter-name>
        <filter-class>com.xyz.FilterI18nCookie</filter-class>
    </filter>
        <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <filter-mapping>
        <filter-name>FilterI18nCookie</filter-name>
        <url-pattern>/ *</url-pattern>
    </filter-mapping>
    <filter-mapping>
            <filter-name>springSecurityFilterChain</filter-name>
            <url-pattern>/ *</url-pattern>
    </filter-mapping>
    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

根据A.Masson的建议,我做了一些更改,以支持任何类型的LocalResolver实现。

/**
 * Transfert the value of user Locale into LocaleContextHolder which is used by spring-security
 */
public class FilterI18nSpringSecurity implements Filter {
    private static final Logger LOG = LoggerFactory.getLogger(FilterI18nSpringSecurity.class);

    private WebApplicationContext springContext;

    /**
     * @see javax.servlet.Filter#doFilter(javax.servlet.ServletRequest,
     *      javax.servlet.ServletResponse, javax.servlet.FilterChain)
     */
    public void doFilter(ServletRequest pRequest, ServletResponse pResponse, FilterChain pFilterChain) throws IOException, ServletException {
        if (!(pRequest instanceof HttpServletRequest)) {
            pFilterChain.doFilter(pRequest, pResponse);
            return;
        }

        LocaleResolver bean = springContext.getBean(LocaleResolver.class);
        Locale locale = bean.resolveLocale((HttpServletRequest) pRequest);
        LOG.info("Locale -> " + locale);
        LocaleContextHolder.setLocale(locale, true);

        pFilterChain.doFilter(pRequest, pResponse);
    }

    /**
     * @see javax.servlet.Filter#init(javax.servlet.FilterConfig)
     */
    public void init(FilterConfig filterConfig) throws ServletException {
        springContext = WebApplicationContextUtils.getWebApplicationContext(filterConfig.getServletContext());
    }

    /**
     * @see javax.servlet.Filter#destroy()
     */
    public void destroy() {
    }

}

修改: 以前的方法在某些情况下不起作用。我改变了这个,改善了行为。 我使用Spring异常类名作为消息键,因此我可以在当前属性文件中映射这些消息。 (我的模板引擎是百里香)

在页面中:

<th:block th:if="${session.SPRING_SECURITY_LAST_EXCEPTION != null &amp;&amp; param.error != null}">
    <div th:replace="fragments/alert :: alert (type='danger', message=#{${session.SPRING_SECURITY_LAST_EXCEPTION.class.name}})">Alert</div>
</th:block>

messages.properties:

org.springframework.security.authentication.BadCredentialsException=Usuario o contraseña... org.springframework.security.authentication.LockedException=Usuario bloqueado org.springframework.security.authentication.DisabledException=El usuario está deshabilitado
