Question

我对UTF-8字符有疑问。我尝试了许多解决方案，但没有任何工作对我有用。我现在所拥有的：

Tomcat（server.xml）：

<Connector URIEncoding="UTF-8" useBodyEncodingForURI="true" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

基本配置类：

public class HomeInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
    return new Class[] { WebSecurityConfig.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
    return new Class[] { WebMvcConfiguration.class };
}
@Override
protected String[] getServletMappings() {
    return new String[] { "/" };
}
@Override
protected Filter[] getServletFilters() {
    CharacterEncodingFilter filter = new CharacterEncodingFilter();
    filter.setEncoding("UTF-8"); // forcing UTF-8
    filter.setForceEncoding(true);
    return new Filter[] { filter };
}
}

包含Thymeleaf配置的WebMvcConfiguration类：

@Bean
public ThymeleafViewResolver viewResolver() {
    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(templateEngine());
    viewResolver.setCharacterEncoding("UTF-8"); // forcing UTF-8
    viewResolver.setContentType("text/html; charset=UTF-8");
    viewResolver.setOrder(1);
    viewResolver.setViewNames(new String[] { ".html", ".xhtml" });
    return viewResolver;
}
@Bean
public SpringResourceTemplateResolver templateResolver() {
    SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
    templateResolver.setCharacterEncoding("UTF-8"); // forcing UTF-8
    templateResolver.setApplicationContext(applicationContext);
    templateResolver.setPrefix("/WEB-INF/views/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode(TemplateMode.HTML);
    templateResolver.setCacheable(true);
    return templateResolver;
}
@Bean
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(templateResolver());
    templateEngine.setEnableSpringELCompiler(true);
    return templateEngine;
}
@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    registry.viewResolver(resolver);
}

WebSecurityConfig，其中包含其余配置：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests().anyRequest().anonymous().antMatchers("/login**", "/*.js", "/*.css", "/*.svg").permitAll().anyRequest().authenticated()
                    .antMatchers("/login**").permitAll().and().formLogin().loginPage("/login").loginProcessingUrl("/login").usernameParameter("username")
                    .passwordParameter("password").defaultSuccessUrl("/", true).permitAll().and().logout()
                    .logoutRequestMatcher(new AntPathRequestMatcher("/logout")).logoutSuccessUrl("/login?logout").deleteCookies("JSESSIONID")
                    .invalidateHttpSession(true).permitAll();
    CharacterEncodingFilter filter = new CharacterEncodingFilter();
    filter.setEncoding("UTF-8"); // another forcing UTF-8
    filter.setForceEncoding(true);
    http.addFilterBefore(filter, CsrfFilter.class);
}

所有html页面均包含：

<meta http-equiv='Content-Type' content='text/html; charset=UTF-8' />

在我添加Thymeleaf并使用jsp之前，我已经能够显示特殊字符
还检查了所有文件（.html）是否都使用UTF-8编码
更改了Eclipse设置以将所有内容保留在UTF-8中
检查了可能与此问题有关的堆栈溢出问题的所有答案，并验证了排名较高的所有答案（包括this，this和that）
已检查的Thymeleaf消息传递解决方案（some stack question for that）
转义字符\u0119按原样显示-\u0119
使用相同的pom.xml，Spring / Thymeleaf配置创建了新项目

然后静止，而不是波兰语 ąęłźżńłó 我有 ???????ó 显示在页面上。有什么想法吗？

不幸的是我没有 web.xml 整个配置使用注释。 ~~我无法控制 Filter 课程顺序~~-参见can use @Order annotation

使用的技术：Spring Framework 5.1.6，Spring Security 5.1.5，Thymeleaf 3.0.11，Thymeleaf Spring security4 3.0.4，Maven 4，Tomcat 9。

很遗憾，我必须回答自己的问题。

要从属性文件读取UTF-8数据，只需使用编码属性

@Component
@PropertySource(value = "classpath:config/data.properties", encoding = "UTF-8")

基本上，是在configureViewResolvers方法中添加了一些其他方法调用的原因：

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        ThymeleafViewResolver resolver = new ThymeleafViewResolver();
        resolver.setTemplateEngine(templateEngine());
        resolver.setCharacterEncoding("UTF-8"); // <- this was added
        resolver.setForceContentType(true); // <- this was added
        resolver.setContentType("text/html; charset=UTF-8"); // <- this was added
        registry.viewResolver(resolver);
    }

和configure(HttpSecurity http)方法中的其他方法，我更改了添加过滤器的方式：

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        CharacterEncodingFilter filter = new CharacterEncodingFilter();
        filter.setEncoding("UTF-8");
        filter.setForceEncoding(true);

        http.authorizeRequests().anyRequest().anonymous()
        .antMatchers("/login**", "/*.js", "/*.css", "/*.svg" ).permitAll()
        // ... some other config
        .invalidateHttpSession(true)
        .permitAll()
        .and()
        .addFilterBefore(filter, CsrfFilter.class); // <- this was added
    }

Answer 2

因此，这似乎很有用，但是您是否导航到目录结构，右键单击包含页面的文件夹，然后选择“刷新”？

我不知道您使用的是什么IDE，但是在过去，我不得不手动进入Eclipse并刷新包含静态内容的软件包。

如果不执行此操作，则不会接受更改。
