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，这可能是因为我的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（）方法在AbstractAnnotationConfigDispatcherServletInitializer类中注册过滤器：

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};
    }
}

但这不起作用。有没有人遇到过同样的问题，或者有一些想法如何解决这个问题？

以下是我通过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);
    }
}

依赖关系：

spring-mvc 3.2.5.RELEASE

spring-security-config，spring-security-web，spring-security-core 3.2.0.RELEASE

Answer 1

我们需要在第一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
}

Answer 2

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（这里是你的代码，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表示：

isMatchAfter - 如果给定的过滤器映射应该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的任何已声明的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。而是在web.xml中正确地做 - 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：在 Spring Security过滤器链之前（即DelegatingFilterProxy的过滤器映射之前）配置此过滤器的映射。

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，此问题仅适用于Tomcat，但不适用于Jetty。

Answer 5

我用过

@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
}

Answer 6

我不喜欢到目前为止发布的答案，因为要么使用模糊的Spring类，要么依赖于实现细节。

在我看来，事情应该只需定义一个标准@Bean高@Order，所以这是Boot的错 - 但幸运的是，如果我们使用的话，一切都按预期工作（？） FilterRegistrationBean代替普通Filter（我使用Boot 1.1.5）：

@Bean
public FilterRegistrationBean filterRegistrationBean() {
    FilterRegistrationBean registrationBean = new FilterRegistrationBean();
    CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
    registrationBean.setFilter(characterEncodingFilter);
    characterEncodingFilter.setEncoding("UTF-8");
    characterEncodingFilter.setForceEncoding(true);
    registrationBean.setOrder(Integer.MIN_VALUE);
    registrationBean.addUrlPatterns("/*");
    return registrationBean;
}

CharacterEncodingFilter不能与Spring Security 3.2.0一起使用
