单点登录流程-2

编写一个隐藏的input框，用于存储调回的url

cfmall-test-sso-server/src/main/java/com/gyz/cfmall/controller/LoginController.java

package com.gyz.cfmall.controller;

import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;

import javax.annotation.Resource;
import java.util.UUID;

@Controller
public class LoginController {

    @GetMapping("/login.html")
    public String login(@RequestParam("redirect_url") String url, Model model) {

        model.addAttribute("url", url);
        return "login";
    }
 
    //代码省略...
}

cfmall-test-sso-server/src/main/resources/templates/login.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>欢迎登录</title>
</head>
<body>
<form action="/doLogin" method="post">
    用户名 <input type="text" name="username"/><br/>
    密 码 <input name="password" type="passWord"/><br/>
    <input type="hidden" name="redirect_url" th:value="${url}"/>
    <input type="submit" value="登录"/>
</form>
</body>
</html>

导入redis依赖

cfmall-test-sso-server/pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

配置redis信息

cfmall-test-sso-server/src/main/resources/application.properties

spring.redis.host=192.168.17.130
spring.redis.port=6379

登录成功保存用户信息并传递token

cfmall-test-sso-server/src/main/java/com/gyz/cfmall/controller/LoginController.java

package com.gyz.cfmall.controller;

import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;

import javax.annotation.Resource;
import java.util.UUID;

@Controller
public class LoginController {

    @Autowired
    private StringRedisTemplate redisTemplate;

	//代码省略...
	
    /**
     * 处理登录请求
     *
     * @return
     */
    @GetMapping("/doLogin")
    public String doLogin(@RequestParam("username") String username,
                          @RequestParam("password") String password,
                          @RequestParam("redirect_url") String url) {

        if (!StringUtils.isEmpty(username) && !StringUtils.isEmpty(password)) {
            String uuid = UUID.randomUUID().toString().replace("-", "");
            redisTemplate.opsForValue().set(uuid, username);
            return "redirect:" + url + "?token=" + uuid;
        }
        return "login";
    }
}

拿到令牌需要去认证中心查询用户的信息，这里只是简单保存了以下并没有模拟

cfmall-test-sso-client/src/main/java/com/gyz/cfmall/controller/HelloController.java

@GetMapping("/employees")
public String employees(Model model, HttpSession session, @RequestParam(value = "token", required = false) String token) {
    if (!StringUtils.isEmpty(token)) {
        //TODO：去认证中心查询用户信息
        model.addAttribute("loginUser", "zhangsan");
    }

    Object loginUser = session.getAttribute("loginUser");
    if (loginUser == null) {
        return "redirect:" + SSOServerUrl + "?redirect_url=http://client1.com:8083/employees";
    } else {
        List<Object> emps = new ArrayList<>();
        emps.add("zhangsan");
        emps.add("lisi");
        model.addAttribute("emps", emps);
        return "employees";
    }
}
