JAVA Oauth 认证服务器的搭建

http://blog.csdn.net/binyao02123202/article/details/12204411

1、软件下载

Oauth服务端： http://code.google.com/p/oauth/ 
通过SVN，下载源码。

或者下载站长整合好的示例源码：http://115.com/file/aqvpzqhz

客户端下载：http://code.google.com/p/oauth-signpost/  oauth-signpost

或者下载站长整合好的示例源码：http://115.com/file/bhy1d2ce

2、服务端源码下载后，把相关代码整合在一起（或直接下载站长整合好的代码），修改net.oauth.provider.core.SampleOAuthProvider  类，把从 provider.properties 读取的信息改为从数据库中读取，如APP_KEY、APP_SCERET、描述、回调地址。

3、net.oauth.example.provider.servlets下面的四个类，这里对应着oauth3个请求url，跟一个用于测试的链接，可以根据需求修改，如将调用Oauth的用户信息记录下来。

4、修改web.xml 增加三个请求url

01

<servlet>

02	<servlet-name>request_token</servlet-name>

03	<servlet-class>net.oauth.provider.servlets.RequestTokenServlet</servlet-class>

04	</servlet>

05	<servlet-mapping>

06	<servlet-name>request_token</servlet-name>

07	<url-pattern>/oauth/request_token</url-pattern>

08	</servlet-mapping>

09

10

<servlet>

11	<servlet-name>access_token</servlet-name>

12	<servlet-class>net.oauth.provider.servlets.AccessTokenServlet</servlet-class>

13	</servlet>

14	<servlet-mapping>

15	<servlet-name>access_token</servlet-name>

16	<url-pattern>/oauth/access_token</url-pattern>

17	</servlet-mapping>

18

19

<servlet>

20	<servlet-name>authorize</servlet-name>

21	<servlet-class>net.oauth.provider.servlets.AuthorizationServlet</servlet-class>

22	</servlet>

23	<servlet-mapping>

24	<servlet-name>authorize</servlet-name>

25	<url-pattern>/oauth/authorize</url-pattern>

26	</servlet-mapping>

5、做个拦截器，只要通过某url访问的都需要进行Oauth认证：

web.xml

1

<filter>

2	<filter-name>OauthFilter</filter-name>

3	<filter-class>web.school.phone.OauthFilter</filter-class>

4

</filter>

5	<filter-mapping>

6	<filter-name>OauthFilter</filter-name>

7	<url-pattern>/phone/*</url-pattern>

8	</filter-mapping>

web.school.phone.OauthFilter

01	package web.school.phone;

02	import java.io.IOException;

03

04	import javax.servlet.Filter;

05	import javax.servlet.FilterChain;

06	import javax.servlet.FilterConfig;

07	import javax.servlet.ServletException;

08	import javax.servlet.ServletRequest;

09	import javax.servlet.ServletResponse;

10	import javax.servlet.http.HttpServletRequest;

11	import javax.servlet.http.HttpServletResponse;

12

13	import net.oauth.OAuthAccessor;

14	import net.oauth.OAuthMessage;

15	import net.oauth.provider.core.SampleOAuthProvider;

16	import net.oauth.server.OAuthServlet;

17

18	public class OauthFilter implements Filter {

19

20	public void destroy() {

21

}

22

23	public void init(FilterConfig fConfig) throws ServletException {

24

}

25

26	public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)

27	throws IOException, ServletException {

28	HttpServletRequest req=(HttpServletRequest)request;

29	HttpServletResponse res=(HttpServletResponse)response;

30

31

try{

32	OAuthMessage requestMessage = OAuthServlet.getMessage(req, null);

33	OAuthAccessor accessor = SampleOAuthProvider.getAccessor(requestMessage);

34	SampleOAuthProvider.VALIDATOR.validateMessage(requestMessage, accessor);

35

36	System.out.println("[OauthFilter:passed]:"+req.getRequestURI());

37	chain.doFilter(request, response);//验证通过则转向

38

39	} catch (Exception e){

40

//验证不通过

41	SampleOAuthProvider.handleException(e, req, res, false);

42

}

43

44

}

45

46

}

6、执行客户端代码，提示输入验证码时，把控制台打印的URL放到浏览器里打开，输入授权码：

（服务端AuthorizationServlet 里面修改验证不通过要跳转的页面，页面上会打印一些参数）
