认证失败处理类

自定义退出处理类

自定义token认证过滤器

package ***.***.framework.security.filter;

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

import org.springframework.beans.factory.annotation.Autowired;

@Component
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter {
    @Autowired
    private TokenService tokenService;

            throws ServletException, IOException {
        //放行websocket相关请求
        if (request.getRequestURI().contains("/webSocket")) {
            chain.doFilter(request, response);
            return;
        }

            SecurityContextHolder.getContext().setAuthentication(authenticationToken);
        }
        chain.doFilter(request, response);

自定义跨域配置

/**

     */
    @Bean
    public CorsFilter corsFilter()
    {
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        // 设置访问源地址
        config.addAllowedOriginPattern("*");
        // 设置访问源请求头
        config.addAllowedHeader("*");
        // 设置访问源请求方法
        config.addAllowedMethod("*");
        // 有效期 1800秒
        config.setMaxAge(1800L);
        // 添加映射路径，拦截一切请求
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", config);
        // 返回新的CorsFilter
        return new CorsFilter(source);
    }

工具类获取每次客户端请求用户信息

/**
     * 获取Authentication
     */
    public static Authentication getAuthentication() {
    //此处设置的值见 token过滤器 验证token有效性处代码 SecurityContextHolder.getContext().setAuthentication(authenticationToken);
        return SecurityContextHolder.getContext().getAuthentication();
    }
