Question

我在我的网络应用程序中使用Spring MVC和Freemarker 2.3.27，当我尝试显示俄文时，我只有“?????”。我在utf-8中保存了我的ftl页面并添加了meta：

<!DOCTYPE html>
    <html >
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        <!-- Latest compiled and minified CSS -->
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"

        <title>Registration</title>
        <#assign contextPath = request.contextPath>
    </head>
    <body>

                <div class="panel-heading">
                    <h3 class="panel-title">Зарегистрируйтесь</h3>
                </div>
                <div class="panel-body">
                    <form method="post"  action="" name="saveUser">
                        <input name="${_csrf.parameterName}" value="${_csrf.token}" type="hidden">

                        <div class="form-group">
                            <@spring.bind "userForm.username"/>
                            <div class="alert-link">
                               <#if spring.status.error>
                                   <div class="alert alert-danger" role="alert">
                                      <#list spring.status.errorMessages as error>
                                         <li>${error}</li>
                                      </#list>
                                   </div>
                               </#if>
                            </div>
                            <label for="username">Username</label>
                            <input type="text" class="form-control" id="username" placeholder="Username" name="username">
                        </div>

                        ...
                    </form>
                </div>

<body/>
<html/>

这是我的WebConfig：

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "aquaplant")
public class WebConfig extends WebMvcConfigurerAdapter {
.....
    @Bean
    public FreeMarkerConfigurer getFreeMarkerConfigurer() {
        FreeMarkerConfigurer configurer = new DefaultFreeMarkerConfigurer();
        configurer.setDefaultEncoding("UTF-8");
        configurer.setTemplateLoaderPaths("/", "/WEB-INF/views");
        return configurer;
    }
    @Bean(name = "messageSource")
    public ReloadableResourceBundleMessageSource getMessageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasenames("classpath:validation");
        messageSource.setDefaultEncoding("UTF-8");
        //messageSource.setUseCodeAsDefaultMessage(true);
        return messageSource;
    }
}

在我的整个程序中，我使用utf-8。它应该工作，但事实并非如此。有人能帮助我吗？

通过创建这样的过滤器解决了这个问题：

public class CharsetFilter implements Filter {

    private String encoding;
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        encoding = filterConfig.getInitParameter("requestEncoding");
        if (encoding == null) encoding = "UTF-8";
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        if (request.getCharacterEncoding()==null) {
            request.setCharacterEncoding(encoding);
        }
        response.setContentType("text/html; charset=UTF-8");
        response.setCharacterEncoding("UTF-8");
        chain.doFilter(request, response);
    }

    @Override
    public void destroy() {

    }
}

必须将此过滤器添加到servletContext：

public class WebAppInitializer implements WebApplicationInitializer {
    public void onStartup(ServletContext servletContext) throws ServletException {
        CharsetFilter filter = new CharsetFilter();
        servletContext.addFilter("charsetFilter", filter).addMappingForUrlPatterns(null, false, "/*");
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.register(SpringConfig.class, WebConfig.class);
        context.setServletContext(servletContext);
        ServletRegistration.Dynamic dispatcher11 = servletContext.
                addServlet("dispatcher11", new DispatcherServlet(context));
        dispatcher11.setLoadOnStartup(1);
        dispatcher11.addMapping("/");
    }
}

俄文显示为???在我的FTL页面中
