Java中的过滤器和拦截器有什么区别么？

public interface Filter {
    //用于执行过滤器的初始化工作，web容器会在web项目启动时自动调用该方法
    default void init(FilterConfig filterConfig) throws ServletException {
    }
 
    //当请求和响应被过滤器拦截后，都会交给doFilter来处理:其中两个参数分别是被拦截request和response对象，可以使用chain的doFliter方法来放行
    void doFilter(ServletRequest var1, ServletResponse var2, FilterChain var3) throws IOException, ServletException;
    //用于释放关闭Filter对象打开的资源，在web项目关闭时，由web容器自动调用该方法
    default void destroy() {
    }
}

@Component
@Slf4j
public class MyFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        log.info("初始化过滤器：" + filterConfig.getFilterName());
    }

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

        HttpServletRequest httpRequest = (HttpServletRequest) request;
        HttpServletResponse httpResponse = (HttpServletResponse) response;

        // 对请求进行过滤操作处理
        log.info("MyFilter 开始对请求进去过滤操作！");
        String requestURI = httpRequest.getRequestURI();
        log.info("请求地址：" + requestURI);

        // 继续执行下一个 Filter，如果没有其他 Filter 的话就执行 Controller 层代码
        long startTime = System.currentTimeMillis();
        chain.doFilter(request, response);

        // 执行完用户请求后，回到这里对 response 响应内容做一些处理
        long endTime = System.currentTimeMillis();
        log.info("请求处理完毕，所花费时间为：" + (endTime - startTime) + "ms");
    }
