Spring MVC @ModelAttribute 参数乱码

issue
Spring MVC提交form表单后台通过@ModelAttribute获取参数为乱码
Spring MVC submit form and get random code parameters through `@ModelAttribute

Java Config WebInitializer

傻了，将CharacterEncodingFilter部分放到DispatcherServlet部分前面就可以了

public class WebInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(javax.servlet.ServletContext sc) throws ServletException {
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(ApplicationConfig.class);
        sc.addListener(new ContextLoaderListener(rootContext));

        //CharacterEncodingFilter
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        FilterRegistration filterRegistration =
                sc.addFilter("characterEncodingFilter", characterEncodingFilter);
        filterRegistration.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), false, "/*");//注意这里匹配 "/*"

        //follow can be deleted
        //sc.addFilter("hibernateFilter", OpenSessionInViewFilter.class).addMappingForUrlPatterns(null, false, "/*");

        //maybe follow will be use
        // sc.addFilter("OpenEntityManagerInViewFilter", org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter.class).addMappingForUrlPatterns(null, false, "/*");

        //springmvc上下文
        AnnotationConfigWebApplicationContext springMvcContext = new AnnotationConfigWebApplicationContext();
        springMvcContext.register(MvcConfig.class);

        //DispatcherServlet
        DispatcherServlet dispatcherServlet = new DispatcherServlet(springMvcContext);
        dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
        ServletRegistration.Dynamic dynamic = sc.addServlet("dispatcherServlet", dispatcherServlet);
        dynamic.setLoadOnStartup(1);
        dynamic.addMapping("/");


    }
}
