spring-mvc - CharacterEncodingFilter不能与Spring Security 3.2.0一起使用

Question

我是Spring MVC框架的新手，但遇到一个我自己无法解决的问题。当我将Spring Security与我的应用程序集成后，一切都开始了，之后HTML表单中的所有unicode值都未编码(Spring Security正常工作)。我得出结论，这可能是因为我的DelegatingFilterProxy被称为链中的第一个过滤器而发生的。

这是我认为可以使用的配置，但无效:

1)我正在从Javadoc扩展AbstractSecurityWebApplicationInitializer-

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

从该类中，我还重写了有关javadoc的beforeSpringSecurityFilterChain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。

我烦的另一个选择是通过重写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};
    }
}

但是，这也不起作用。是否有人遇到相同的问题或有解决此问题的想法？

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);
    }
}

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。
