2.MVC页面跳转配置类，如果请求直接跳转页面，采用该配置可以减少controller中代码的编写
package com.xicheng.ssodemo.common;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
/**
* @author xichengxml
* @date 2019/2/13 16:56
*/
@Configuration
public class SpringMvcConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("login").setViewName("login");
registry.addViewController("success").setViewName("success");
registry.addViewController("error").setViewName("error");
}
}3.核心校验类编写
package com.xicheng.ssodemo.common;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
/**
* @author xichengxml
* @date 2019/2/13 16:19
* 登录校验工具类
*/
public class LoginCheck {
/** 用户名 */
private static final String USERNAME = "uname";
/** 密码 */
private static final String PASSWORD = "pwd";
/** cookie键 */
public static final String COOKIE_KEY = "sso";
/** cookie值 */
public static final String COOKIE_VAL = "ssocookie";
/**
* 校验用户名和密码
* @param userName 登录用户名
* @param password 登录密码
* @return 成功返回true; 失败返回false
*/
public static boolean checkLogin(String userName, String password) {
return USERNAME.equals(userName) && PASSWORD.equals(password);
}
/**
* 校验cookie
* @param request
* @return
*/
public static boolean checkCookie(HttpServletRequest request) {
Cookie[] cookies = request.getCookies();
if (cookies != null && cookies.length != 0) {
for (Cookie cookie : cookies) {
if (COOKIE_KEY.equals(cookie.getName()) && COOKIE_VAL.equals(cookie.getValue())) {
return true;
}
}
}
return false;
}
}4.核心登录controller编写
package com.xicheng.ssodemo.controller;
import com.xicheng.ssodemo.common.LoginCheck;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletResponse;
/**
* @author xichengxml
* @date 2019/2/13 16:31
*/
@Controller
public class LoginController {
/**
* 登录成功后保存cookie在域下，返回登录成功页
* @param uname
* @param pwd
* @param response
* @return
*/
@RequestMapping("/do-login")
public String doLogin(String uname, String pwd, HttpServletResponse response) {
if (LoginCheck.checkLogin(uname, pwd)) {
Cookie cookie = new Cookie(LoginCheck.COOKIE_KEY, LoginCheck.COOKIE_VAL);
cookie.setPath("/");
response.addCookie(cookie);
return "success";
}
return "error";
}
}5.登录controller编写
package com.xicheng.ssodemo.controller;
import com.xicheng.ssodemo.common.LoginCheck;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
/**
* @author xichengxml
* @date 2019/2/13 17:53
*/
@Controller
public class SameOriginController {
/**
* cookie存在，登录成功；否则返回登录页
* @param request
* @return
*/
@RequestMapping("/login01")
public String demo01(HttpServletRequest request) {
return LoginCheck.checkCookie(request) ? "success" : "login";
}
@RequestMapping("/login02")
public String demo02(HttpServletRequest request) {
return LoginCheck.checkCookie(request) ? "success" : "login";
}
}6.登录页面及成功失败页面编写
