如何在SpringBoot中配置CharacterEncodingFilter？

上面的注释中建议的Application.java类的示例代码：

@Beanpublic FilterRegistrationBean filterRegistrationBean() {    FilterRegistrationBean registrationBean = new FilterRegistrationBean();    CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();    characterEncodingFilter.setForceEncoding(true);    characterEncodingFilter.setEncoding("UTF-8");    registrationBean.setFilter(characterEncodingFilter);    return registrationBean;}
