java - Spring -OAUTH2.0 : No resource available error on calling/oauth/token

Question

我们有一组需要使用 OAUTH2.0 保护的 ReST 网络服务。我正在尝试通过引用以下资源来实现 OAUTH2.0:

• > Spring-security context setup for 2-legged (client credentials) OAuth2 server
• > http://www.e-zest.net/blog/rest-authentication-using-oauth-2-0-resource-owner-password-flow-protocol/

但是，在完成所需配置后，我尝试访问 URL
http://localhost:8080/{project-name}/oauth/token?grant_type=password&client_id=client1&client_secret=client1&username =admin&password=admin

Tomcat 抛出错误 - 请求的资源不可用。

当我尝试在 ClientDetailsS​​erviceImpl.java 中放置一个调试点时，流程以正确的细节到达那里。无法理解我在这里做错了什么。任何建议表示赞赏。 TIA。

Answer 1

在您的 web.xml 中，您需要一个带有指向/oauth/token 的 url-pattern 属性的 servlet-mapping 标记

类似于:

<servlet-mapping>
    <servlet-name>spring <!-- Or whatever your dispatch servlet is called --></servlet-name>
    <url-pattern>/oauth/token</url-pattern>
</servlet-mapping>
