【Spring Security】使用 OncePerRequestFilter 过滤器校验登录过期、请求日志等操作

前言

OncePerRequestFilter 是一个过滤器，每个请求都会执行一次；一般开发中主要是做检查是否已登录、Token是否过期和授权等操作，而每个操作都是一个过滤器，下面演示一下。

OncePerRequestFilter 使用

检查是否登录过期过滤器

import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**
 * 检查是否登录过期

 **/
@Component
@Slf4j
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        log.info("进入 JwtAuthenticationTokenFilter ...");
        /**
         * 从 request 的 header 中拿出来 token
         */

        String token = request.getHeader("token");
        if (token == null || token.isEmpty()) {
            // 没有携带 token 则 放行
            filterChain.doFilter(request, response);
            return;
        }

        /**
         * 检查 token 是否过期逻辑 .....
         */
        // 放行
        filterChain.doFilter(request, response);
    }
}
