我在学习Spring Boot时遇到了一些编码问题；我想添加一个像Spring 3.x一样的CharacterEncodingFilter。像这样：

<filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

回答：

上面的注释中建议的Application.java类的示例代码：

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