I cannot get the right UTF-8 encoding in Spring MVC - spring

Question

I have a problem with UTF-8 character (for example ěčžýáí). I find some solutions on Stack Overflow but it doesn't work for me. Here is my Conf class. I'm not using web.xml, everything is via annotation.
#Configuration
#EnableWebMvc
#Import({ SecurityConfig.class })
#ComponentScan(basePackages = "cz.prosvaly")
public class AppConfig {
#Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
#Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
}
#Bean(name="multipartResolver")
public CommonsMultipartResolver multipartResolver(){
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
multipartResolver.setMaxUploadSize(10000000);
return multipartResolver;
}
}
Here is my filter for encoding:
public class AppInitializer implements WebApplicationInitializer {
public void onStartup(ServletContext container) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(AppConfig.class);
ctx.setServletContext(container);
container.addListener(new ContextLoaderListener(ctx));
FilterRegistration.Dynamic fr = container.addFilter("encodingFilter",
new CharacterEncodingFilter());
fr.setInitParameter("encoding", "UTF-8");
fr.setInitParameter("forceEncoding", "true");
fr.addMappingForUrlPatterns(null, true, "/*");
ServletRegistration.Dynamic servlet = container.addServlet(
"dispatcher", new DispatcherServlet(ctx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
}
}
Dispatcher config:
#Configuration
public class DispatcherConfig extends WebMvcConfigurerAdapter {
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
// registry.addResourceHandler("/css/**").addResourceLocations("/resources/css/");
// registry.addResourceHandler("/html/**").addResourceLocations("/html/");
// registry.addResourceHandler("/images/**").addResourceLocations("/images/");
}
}
Spring security
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
DataSource dataSource;
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.jdbcAuthentication().dataSource(dataSource).
usersByUsernameQuery("select username,password, enabled from admin where username=?").
authoritiesByUsernameQuery("select username, role from user_roles where username =? ")
.passwordEncoder(new Md5PasswordEncoder());
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")
.and().formLogin()
.loginPage("/login").defaultSuccessUrl("/admin/goods").failureUrl("/login?error")
.usernameParameter("username").passwordParameter("password")
.and().logout().logoutUrl("/logout").logoutSuccessUrl("/login?logout")
.and().csrf();
}
}
public class SpringSecurityInitializer extends AbstractSecurityWebApplicationInitializer {
//do nothing
}
In form that I'm sending on server I have this taglib:
<%# page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
I tried update in Tomcat this row:
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>
But when I submit the form I see this in the log
....type for žÄáížíé

(Posted on behalf of the OP:)
I have to deleted SpringSecurityInitializer and create filter via the following code in in AppInitializer:
fr = container.addFilter("springSecurityFilterChain",
new DelegatingFilterProxy());
fr.addMappingForUrlPatterns(null, true, "/*");
