Spring Boot 提供了多種在 Web 應用程式中註冊過濾器的方法。對於自訂過濾器,通常使用 FilterRegistrationBean bean。
要使用FilterRegistrationBean 新增自訂過濾器,請依照下列步驟操作:
建立@Configuration 類別中的新bean:
<code class="java">@Bean public FilterRegistrationBean filterRegistration() { FilterRegistrationBean registration = new FilterRegistrationBean(); registration.setFilter(customFilter()); registration.addUrlPatterns("/url/*"); registration.setName("customFilter"); registration.setOrder(1); return registration; }</code>
定義實際的過濾器實作:
<code class="java">public class CustomFilter implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { // Initialization logic here } @Override public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { // Filter logic here filterChain.doFilter(servletRequest, servletResponse); } @Override public void destroy() { // Destroy logic here } }</code>
將過濾器配置自訂為需要,例如:
