非spring boot项目整合SSO

[zhaojieip]

1.将XxlSsoWebFilter.java 放入项目中
`package com.xxl.sso.core.filter;

import com.xxl.sso.core.conf.Conf;
import com.xxl.sso.core.login.SsoWebLoginHelper;
import com.xxl.sso.core.path.impl.AntPathMatcher;
import com.xxl.sso.core.user.XxlSsoUser;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

2.web.xml加入配置

XxlSsoWebFilter
com.it.config.XxlSsoWebFilter

sso_server
http://你的IP:端口/xxl-sso-server


SSO_LOGOUT_PATH
/logout


SSO_EXCLUDED_PATHS




XxlSsoWebFilter
