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">

<body>
<div class="panel-heading">

<div class="panel-body">

这是我的Web配置：
@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。有谁能够帮我？
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("/");
}
}
