我看到Vasily Komarov的答案。这里有一个类似的方法，但是使用抽象的HandlerInterceptorAdapter类而不是使用HandlerInterceptor。

这里有一个例子……

@Component
public class CustomInterceptor extends HandlerInterceptorAdapter {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
        throws Exception {
    }
}

@Configuration
public class InterceptorConfig extends WebMvcConfigurerAdapter {

    @Autowired
    private CustomInterceptor customInterceptor ;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(customInterceptor );
    }

}

用一个Spring原型(如@Component)注释你的过滤器。在Spring @Configuration中注册一个Filter类型的@Bean。在Spring @Configuration中用FilterRegistrationBean类型注册一个@Bean。

使用@WebFilter注释，可以这样做:

@WebFilter(urlPatterns = {"/*" })
public class AuthenticationFilter implements Filter{

    private static Logger logger = Logger.getLogger(AuthenticationFilter.class);

    @Override
    public void destroy() {
        // TODO Auto-generated method stub

    }

    @Override
    public void doFilter(ServletRequest arg0, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

         logger.info("checking client id in filter");
        HttpServletRequest request = (HttpServletRequest) arg0;
        String clientId = request.getHeader("clientId");
        if (StringUtils.isNotEmpty(clientId)) {
            chain.doFilter(request, response);
        } else {
            logger.error("client id missing.");
        }
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {
        // TODO Auto-generated method stub

    }

}

Use:

@WebFilter(urlPatterns="/*")
public class XSSFilter implements Filter {

    private static final org.apache.log4j.Logger LOGGER = LogManager.getLogger(XSSFilter.class);

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        LOGGER.info("Initiating XSSFilter... ");
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        HttpServletRequest req = (HttpServletRequest) request;
        HttpRequestWrapper requestWrapper = new HttpRequestWrapper(req);
        chain.doFilter(requestWrapper, response);
    }

    @Override
    public void destroy() {
        LOGGER.info("Destroying XSSFilter... ");
    }

}

你需要实现Filter，并且它需要用@WebFilter(urlPatterns="/*")进行注释。

在Application或Configuration类中，您需要添加@ServletComponentScan。通过此操作，您的筛选器将被注册。

我在这里看到了很多答案，但我没有尝试任何一个。我刚刚创建了如下代码所示的过滤器。

import org.springframework.context.annotation.Configuration;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import java.io.IOException;

@WebFilter(urlPatterns = "/Admin")
@Configuration
public class AdminFilter implements Filter{
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse  servletResponse, FilterChain filterChain) throws IOException, ServletException      {
    System.out.println("happened");

    }

    @Override
    public void destroy() {

    }
}

我让剩下的Spring Boot应用程序保持原样。

添加过滤器有三种方法，

用一个Spring原型(如@Component)注释你的过滤器 在Spring @Configuration中注册一个Filter类型的@Bean 在Spring @Configuration中用FilterRegistrationBean类型注册一个@Bean

Either #1 or #2 will do if you want your filter applies to all requests without customization, use #3 otherwise. You don't need to specify component scan for #1 to work as long as you place your filter class in the same or sub-package of your SpringApplication class. For #3, use along with #2 is only necessary when you want Spring to manage your filter class such as have it auto wired dependencies. It works just fine for me to new my filter which doesn't need any dependency autowiring/injection.

虽然结合#2和#3效果很好，但我很惊讶它最终没有应用两次两个过滤器。我的猜测是，当Spring调用相同的方法来创建这两个bean时，它将这两个bean合并为一个。如果您想单独使用#3和authwiring，您可以使用AutowireCapableBeanFactory。举例如下:

private @Autowired AutowireCapableBeanFactory beanFactory;

    @Bean
    public FilterRegistrationBean myFilter() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        Filter myFilter = new MyFilter();
        beanFactory.autowireBean(myFilter);
        registration.setFilter(myFilter);
        registration.addUrlPatterns("/myfilterpath/*");
        return registration;
    }
