springboot 下使用Filter

添加一个filter配置类，每一个bean配置一个filter属性，然后就可以在HtmlFilter里写过滤逻辑了

@Componentpublic class FilterConfig {    @Bean    public FilterRegistrationBean htmlFilterRegistrationBean() {        FilterRegistrationBean registrationBean = new FilterRegistrationBean();        registrationBean.setName("html filter");        HtmlFilter htmlFilter = new HtmlFilter();        registrationBean.setFilter(htmlFilter);        registrationBean.setOrder(1);        List<String> urlList = new ArrayList<String>();        urlList.add("/admin/*");        registrationBean.setUrlPatterns(urlList);        return registrationBean;    }}
