在Spring Boot中集成Okta的OAuth2授權碼授權流程,你需要遵循以下步驟:
創建Okta開發者帳戶并創建應用程序 首先,你需要在Okta開發者帳戶中創建一個應用程序。創建應用程序后,你將獲得Client ID和Client Secret,這些值將用于配置Spring Boot應用程序。
添加依賴 在你的Spring Boot項目中,添加以下依賴:
<dependency>
<groupId>com.okta.springboot</groupId>
<artifactId>okta-spring-boot-starter</artifactId>
<version>2.1.3</version>
</dependency>
application.properties
或application.yml
文件中,添加以下配置:# application.properties
okta.oauth2.client.client-id=your_client_id
okta.oauth2.client.client-secret=your_client_secret
okta.oauth2.client.redirect-uri=http://localhost:8080/login/callback
okta.oauth2.client.scope=openid,profile,email
okta.oauth2.issuer=https://your_okta_domain/oauth2/default
或者
# application.yml
okta:
oauth2:
client:
client-id: your_client_id
client-secret: your_client_secret
redirect-uri: http://localhost:8080/login/callback
scope: openid,profile,email
issuer: https://your_okta_domain/oauth2/default
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import javax.servlet.http.HttpServletResponse;
@Controller
public class AuthorizationController {
@Autowired
private OktaAuthorizationCodeFlowConfiguration config;
@GetMapping("/login")
public String login() {
return config.getAuthorizationServer().getAuthorizationUrl();
}
@GetMapping("/callback")
public String callback(@RequestParam("code") String code, HttpServletResponse response) {
try {
Authentication authentication = config.getAuthorizationServer().authorizeCodeFlow()
.setAuthorizationRequestBaseUri(config.getAuthorizationServer().getAuthorizationRequestBaseUri())
.setClientCredentials(config.getAuthorizationServer().getClientCredentials())
.setScope(config.getScope())
.setClientId(config.getClientId())
.setClientSecret(config.getClientSecret())
.setRedirectUri(config.getRedirectUri())
.setAuthorizationCode(code)
.execute();
SecurityContextHolder.getContext().setAuthentication(authentication);
return "redirect:/home";
} catch (Exception e) {
response.sendRedirect("/error");
return null;
}
}
}
import org.springframework.security.core.Authentication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class HomeController {
@GetMapping("/home")
public String home(Authentication authentication) {
return "home";
}
}
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class ErrorController {
@GetMapping("/error")
public String error() {
return "error";
}
}
home.html
)中,添加以下內容以顯示用戶的姓名:<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Home</title>
</head>
<body>
<h1>Welcome, <span th:text="${#authentication.name}"></span>!</h1>
</body>
</html>
現在,你已經成功地在Spring Boot應用程序中集成了Okta的OAuth2授權碼授權流程。用戶可以通過訪問/login
URL來登錄并獲取授權碼,然后通過訪問/callback
URL來完成授權過程。成功授權后,用戶將被重定向到主頁,并在頁面上顯示其姓名。
