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。文章来源地址https://www.toymoban.com/news/detail-687156.html

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;

/**

 **/
@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);
    }
}

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;

/**
 * 请求日志
 *
 * @author francis
 * @create: 2023-08-31 10:15
 **/
@Component
@Slf4j
public class OperationLogFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        log.info("OperationLogFilter ...");
        /**
         * 操作日志记录 ...
         */
        // 放行
        filterChain.doFilter(request, response);
    }

}

SecurityConfiguration 配置

import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

/**

@Configuration

public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    private JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter;

    @Autowired
    private OperationLogFilter operationLogFilter;


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                // 关闭csrf
                .csrf().disable()
                // 不通过 Session 获取 SecurityContext
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                    .authorizeRequests()
                        // 对于登录接口 允许匿名访问
                        .antMatchers("/login")
                            .permitAll()
                        // 除上面外的所有请求全部需要鉴权认证
                        .anyRequest()
                            .authenticated();

        // 在 UsernamePasswordAuthenticationFilter（验证用户） 之前执行
        // TODO 需要注意的是下面过滤器的顺序就是执行的顺序，使用 @Order 也没办法改变
        http
        		// 登录是否过期
                .addFilterBefore(jwtAuthenticationTokenFilter, UsernamePasswordAuthenticationFilter.class)
                // 请求日志
                .addFilterBefore(operationLogFilter, UsernamePasswordAuthenticationFilter.class);
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
