CharacterEncodingFilter不能与Spring Security 3.2.0一起使用

Question

我是Spring MVC框架的新手,我遇到了一个我自己无法解决的问题.一切都是在我将spring security与我的应用程序集成后开始的,之后HTML表单中的所有unicode值都没有编码(spring security工作正常).我得出的结论是,这可能是因为我DelegatingFilterProxy被称为链中的第一个过滤器.

这是我认为可以使用的配置,但它没有:

1)我正在从javadoc扩展AbstractSecurityWebApplicationInitializer:

Registers the DelegatingFilterProxy to use the springSecurityFilterChain() before any
other registered Filter.

从那个类我也覆盖了关于javadoc的SpringSecurityFilterChain方法:

Invoked before the springSecurityFilterChain is added.

所以我认为这将是注册CharacterEncodingFilter的最佳位置:

public class MessageSecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
    @Override
    protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
        FilterRegistration.Dynamic characterEncodingFilter = servletContext.addFilter("encodingFilter", new CharacterEncodingFilter());
        characterEncodingFilter.setInitParameter("encoding", "UTF-8");
        characterEncodingFilter.setInitParameter("forceEncoding", "true");
        characterEncodingFilter.addMappingForUrlPatterns(null, true, "/*");
    }
}

但这不起作用.

我厌倦的另一个选择是通过覆盖getServletFilters()方法通过AbstractAnnotationConfigDispatcherServletInitializer类注册过滤器:

public class WebAppInitializer extends
        AbstractAnnotationConfigDispatcherServletInitializer {

    //{!begin addToRootContext}
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { SecurityConfig.class, DatabaseConfig.class, InternationalizationConfig.class };
    }
    //{!end addToRootContext}

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebAppConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

    @Override
    protected Filter[] getServletFilters() {

        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        return new Filter[] { characterEncodingFilter};
    }
}

但这也不起作用.有没有人遇到同样的问题或有一些想法如何解决这个问题？

这是我通过AbstractSecurityWebApplicationInitializer注册编码过滤器的第一个选项的完整配置:

@Order(1)
public class MessageSecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
    @Override
    protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
        FilterRegistration.Dynamic characterEncodingFilter = servletContext.addFilter("encodingFilter", new CharacterEncodingFilter());
        characterEncodingFilter.setInitParameter("encoding", "UTF-8");
        characterEncodingFilter.setInitParameter("forceEncoding", "true");
        characterEncodingFilter.addMappingForUrlPatterns(null, true, "/*");
    }
}

@Order(2)
public class WebAppInitializer extends
        AbstractAnnotationConfigDispatcherServletInitializer {

    //{!begin addToRootContext}
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class<?>[] { SecurityConfig.class, DatabaseConfig.class, InternationalizationConfig.class };
    }
    //{!end addToRootContext}

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[] { WebAppConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }
}

@EnableWebMvc
//@Import(value = {DatabaseConfig.class, InternationalizationConfig.class, SecurityConfig.class})
@ComponentScan(basePackages = {"com.ajurasz.controller", "com.ajurasz.service", "com.ajurasz.model"})
@Configuration
public class WebAppConfig extends WebMvcConfigurerAdapter {

    @Bean
    public UrlBasedViewResolver viewResolver() {
        UrlBasedViewResolver urlBasedViewResolver = new UrlBasedViewResolver();
        urlBasedViewResolver.setViewClass(TilesView.class);
        urlBasedViewResolver.setContentType("text/html;charset=UTF-8");
        return urlBasedViewResolver;
    }

    @Bean
    public TilesConfigurer tilesConfigurer() {
        TilesConfigurer tilesConfigurer = new TilesConfigurer();
        tilesConfigurer.setDefinitions(new String[] {"/WEB-INF/tiles.xml"});
        return tilesConfigurer;
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/**");
        registry.addResourceHandler("/documents/**").addResourceLocations("/WEB-INF/pdfs/documents/**");
    }

    @Override
    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
        PageableHandlerMethodArgumentResolver pageableHandlerMethodArgumentResolver =
                new PageableHandlerMethodArgumentResolver();
        pageableHandlerMethodArgumentResolver.setFallbackPageable(new PageRequest(0, 4, new Sort(Sort.Direction.DESC, "id")));

        argumentResolvers.add(pageableHandlerMethodArgumentResolver);
    }
}

我们需要在首次读取请求属性的过滤器之前添加CharacterEncodingFilter.有securityFilterChain(排在第二位.在公制过滤器之后),我们可以在其中添加我们的过滤器.读取属性的第一个过滤器(内部安全链)是CsrfFilter,因此我们将CharacterEncodingFilter放在它之前.

简短的解决方案是:

@Configuration
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        CharacterEncodingFilter filter = new CharacterEncodingFilter();
        filter.setEncoding("UTF-8");
        filter.setForceEncoding(true);
        http.addFilterBefore(filter,CsrfFilter.class);
        //rest of your code   
    }
//rest of your code
}

我最近遇到了同样的问题,你的第一次尝试实际上非常接近我最终使用的解决方案(这是你的代码,已修复):

public class MessageSecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
@Override
protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
    FilterRegistration.Dynamic characterEncodingFilter = servletContext.addFilter("encodingFilter", new CharacterEncodingFilter());
    characterEncodingFilter.setInitParameter("encoding", "UTF-8");
    characterEncodingFilter.setInitParameter("forceEncoding", "true");
    characterEncodingFilter.addMappingForUrlPatterns(null, false, "/*");
    }
}

唯一的区别是为url模式添加过滤器映射时的第二个参数.此参数的Javadoc指出:

isMatchAfter - 如果给定的过滤器映射应在任何声明的过滤器映射之后匹配,则为true;如果在获得此FilterRegistration的ServletContext的任何已声明过滤器映射之前应该匹配,则为false

因此将其设置为false应该干净地解决您的问题(不涉及任何XML).

我不知道究竟是什么问题,但我永远不会在Spring中配置这么简单的过滤器.而是做得恰到好处web.xml- 更容易开发,理解和调试.

  <!-- Hint: http://wiki.apache.org/tomcat/FAQ/CharacterEncoding#Q8 -->
  <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

重要说明:此配置过滤器的映射之前的春季安全过滤器链(过滤器映射之前即DelegatingFilterProxy).

Answer 4

有同样的问题.我的解决方案是使用原始servlet过滤器:

public void onStartup(ServletContext servletContext) throws ServletException {
      FilterRegistration.Dynamic encodingFilter = servletContext.addFilter("encoding-filter", new CharacterEncodingFilter());
      encodingFilter.setInitParameter("encoding", "UTF-8");
      encodingFilter.setInitParameter("forceEncoding", "true");
      encodingFilter.addMappingForUrlPatterns(null, true, "/*");
}

请注意,此问题仅在Tomcat中发生,而在Jetty中不发生.
