oauth认证 - 润新知

oauth认证
spring-security-oauth2的项目地址为 https://github.com/spring-projects/spring-security-oauth/tree/master/spring-security-oauth2

spring-security-oauth2的demo 地址为 https://github.com/spring-projects/spring-security-oauth/tree/master/samples/oauth2

为什么要写

1. spring-security-oauth2的demo 不容易让开发者理解, 配置的内容很多, 没有分解的步骤; 我曾经试着按照文档(https://github.com/spring-projects/spring-security-oauth/blob/master/docs/oauth2.md) 配置了几次, 结果全失败, 无一成功(说实话, 这是第二次在实际项目中使用spring & oauth,但还是花了不少时间才完全弄清楚);甚至有时候找错误的原因都不好找.

2.Oauth应该属于security的一部分, 但demo并没有将二者分开, 混在一起

3.总结现在, 方便未来

相比于demo,作了哪些改进

1. 将Spring MVC配置与Oauth的配置分开, 互不影响

2.将用户信息存放数据库

3.将ClientDetails数据存放于数据库,并能对数据进行管理

4.扩展ClientDetails基本属性, 添加trusted属性,用于判断Client是否是可信任的

5.取消掉demo中一些不必要的配置

6.针对不同的资源配置不同的权限

7.token存入数据库而不是内存

开始

>>前提: 使用Maven来管理项目; spring-security-oauth的版本号为 1.0.5.RELEASE

1. 添加Maven dependencies; 以下只列出了主要的

```
2. web.xml配置; 这一步与只使用Spring Security的配置一样.
[html] view plain copy print ?
1. </pre><pre code_snippet_id="73897" snippet_file_name="blog_20131119_2_2257675" name="code" class="html"> <filter>

20. </listener>
22. 
23. <servlet>
24. <servlet-name>hy</servlet-name>
25. <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
26. <load-on-startup>2</load-on-startup>
27. </servlet>
28. <servlet-mapping>
29. <servlet-name>hy</servlet-name>
30. <url-pattern>/</url-pattern>
31. </servlet-mapping>
```
</pre><pre code_snippet_id="73897" snippet_file_name="blog_20131119_2_2257675" name="code" class="html">    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/*.xml</param-value>
    </context-param>

    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    
    <servlet>
        <servlet-name>hy</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>hy</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
```
对于Spring MVC, 需要配置文件hy-servlet.xml, 该文件不是这儿关注的(忽略);

在classpath创建spring目录, 在该目录里创建 security.xml 文件, 这是所有步骤配置的重点.

3.security.xml的配置; 重点开始.

3.1 起用注解; TokenEndpoint与AuthorizationEndpoint需要
[html] view plain copy print ?
1. <mvc:annotation-driven/>
2. <mvc:default-servlet-handler/>
```
    <mvc:annotation-driven/>
    <mvc:default-servlet-handler/>
```
3.2 TokenServices 配置

1). TokenStore, 使用JdbcTokenStore, 将token信息存放数据库, 需要提供一个dataSource对象; 也可使用InMemoryTokenStore存于内存中
[html] view plain copy print ?
1. 
2. <beans:bean id="tokenStore" class="org.springframework.security.oauth2.provider.token.JdbcTokenStore">
3. <beans:constructor-arg index="0" ref="dataSource"/>
4. </beans:bean>
```
    
    <beans:bean id="tokenStore" class="org.springframework.security.oauth2.provider.token.JdbcTokenStore">
        <beans:constructor-arg index="0" ref="dataSource"/>
    </beans:bean>
```
注: 可以在spring-security-oauth2中找到对应的SQL脚本, 地址为https://github.com/spring-projects/spring-security-oauth/tree/master/spring-security-oauth2/src/test/resources, 目录中的schema.sql 即是. (以下不再说明SQL脚本的问题)

2).TokenServices; 需要注入TokenStore
[html] view plain copy print ?
1. <beans:bean id="tokenServices" class="org.springframework.security.oauth2.provider.token.DefaultTokenServices">
2. <beans:property name="tokenStore" ref="tokenStore"/>
3. <beans:property name="supportRefreshToken" value="true"/>
4. </beans:bean>
```
    <beans:bean id="tokenServices" class="org.springframework.security.oauth2.provider.token.DefaultTokenServices">
        <beans:property name="tokenStore" ref="tokenStore"/>
        <beans:property name="supportRefreshToken" value="true"/>
    </beans:bean>
```
如果允许刷新token 请将supportRefreshToken 的值设置为true, 默认为不允许

3.3 ClientDetailsService 配置, 使用JdbcClientDetailsService, 也需要提供dataSource, 替换demo中直接配置在配置文件中
[html] view plain copy print ?
1. <beans:bean id="clientDetailsService" class="org.springframework.security.oauth2.provider.JdbcClientDetailsService">
2. <beans:constructor-arg index="0" ref="dataSource"/>
3. </beans:bean>
```
    <beans:bean id="clientDetailsService" class="org.springframework.security.oauth2.provider.JdbcClientDetailsService">
        <beans:constructor-arg index="0" ref="dataSource"/>
    </beans:bean>
```
3.4 ClientDetailsUserDetailsService配置, 该类实现了Spring security中 UserDetailsService 接口
[html] view plain copy print ?
1. <beans:bean id="oauth2ClientDetailsUserService"
2. class="org.springframework.security.oauth2.provider.client.ClientDetailsUserDetailsService">
3. <beans:constructor-arg ref="clientDetailsService"/>
4. </beans:bean>
```
    <beans:bean id="oauth2ClientDetailsUserService"
                class="org.springframework.security.oauth2.provider.client.ClientDetailsUserDetailsService">
        <beans:constructor-arg ref="clientDetailsService"/>
    </beans:bean>
```
3.5 OAuth2AuthenticationEntryPoint配置
[html] view plain copy print ?
1. <beans:bean id="oauth2AuthenticationEntryPoint"
2. class="org.springframework.security.oauth2.provider.error.OAuth2AuthenticationEntryPoint"/>
```
    <beans:bean id="oauth2AuthenticationEntryPoint"
                class="org.springframework.security.oauth2.provider.error.OAuth2AuthenticationEntryPoint"/>
```
3.6 oauth2 AuthenticationManager配置; 在整个配置中,有两个AuthenticationManager需要配置
[html] view plain copy print ?
1. <authentication-manager id="oauth2AuthenticationManager">
2. <authentication-provider user-service-ref="oauth2ClientDetailsUserService"/>
3. </authentication-manager>
```
    <authentication-manager id="oauth2AuthenticationManager">
        <authentication-provider user-service-ref="oauth2ClientDetailsUserService"/>
    </authentication-manager>
```
第二个AuthenticationManager用于向获取UserDetails信息,
[html] view plain copy print ?
1. <authentication-manager alias="authenticationManager">
2. <authentication-provider user-service-ref="userService">
3. <password-encoder hash="md5"/>
4. </authentication-provider>
5. </authentication-manager>
```
    <authentication-manager alias="authenticationManager">
        <authentication-provider user-service-ref="userService">
            <password-encoder hash="md5"/>
        </authentication-provider>
    </authentication-manager>
```
userService是一个实现UserDetailsService的Bean

3.7 OAuth2AccessDeniedHandler配置, 实现AccessDeniedHandler接口
[html] view plain copy print ?
1. <beans:bean id="oauth2AccessDeniedHandler"
2. class="org.springframework.security.oauth2.provider.error.OAuth2AccessDeniedHandler"/>
```
    <beans:bean id="oauth2AccessDeniedHandler"
                class="org.springframework.security.oauth2.provider.error.OAuth2AccessDeniedHandler"/>
```
3.8 UserApprovalHandler配置, 这儿使用DefaultUserApprovalHandler, 这里是实现client是否可信任的关键点,你可以扩展该接口来自定义approval行为
[html] view plain copy print ?
1. <beans:bean id="oauthUserApprovalHandler" class="org.springframework.security.oauth2.provider.approval.DefaultUserApprovalHandler">
2. </beans:bean>
```
    <beans:bean id="oauthUserApprovalHandler" class="org.springframework.security.oauth2.provider.approval.DefaultUserApprovalHandler">
    </beans:bean>
```
3.9 authorization-server配置, 核心
[html] view plain copy print ?
1. <oauth2:authorization-server client-details-service-ref="clientDetailsService" token-services-ref="tokenServices"
2. user-approval-handler-ref="oauthUserApprovalHandler">
3. <oauth2:authorization-code/>
4. <oauth2:implicit/>
5. <oauth2:refresh-token/>
6. <oauth2:client-credentials/>
7. <oauth2:password/>
8. </oauth2:authorization-server>
```
    <oauth2:authorization-server client-details-service-ref="clientDetailsService" token-services-ref="tokenServices"
                                 user-approval-handler-ref="oauthUserApprovalHandler">
        <oauth2:authorization-code/>
        <oauth2:implicit/>
        <oauth2:refresh-token/>
        <oauth2:client-credentials/>
        <oauth2:password/>
    </oauth2:authorization-server>
```
该元素里面的每个标签可设置每一种authorized-grant-type的行为. 如disable refresh-token的配置为
[html] view plain copy print ?
1. <oauth2:refresh-token disabled="true"/>
```
<oauth2:refresh-token disabled="true"/>
```
3.10 Oauth2 AccessDecisionManager配置, 这儿在默认的Spring Security AccessDecisionManager的基础上添加了ScopeVoter
[html] view plain copy print ?
1. <beans:bean id="oauth2AccessDecisionManager" class="org.springframework.security.access.vote.UnanimousBased">
2. <beans:constructor-arg>
3. <beans:list>
4. <beans:bean class="org.springframework.security.oauth2.provider.vote.ScopeVoter"/>
5. <beans:bean class="org.springframework.security.access.vote.RoleVoter"/>
6. <beans:bean class="org.springframework.security.access.vote.AuthenticatedVoter"/>
7. </beans:list>
8. </beans:constructor-arg>
9. </beans:bean>
```
    <beans:bean id="oauth2AccessDecisionManager" class="org.springframework.security.access.vote.UnanimousBased">
        <beans:constructor-arg>
            <beans:list>
                <beans:bean class="org.springframework.security.oauth2.provider.vote.ScopeVoter"/>
                <beans:bean class="org.springframework.security.access.vote.RoleVoter"/>
                <beans:bean class="org.springframework.security.access.vote.AuthenticatedVoter"/>
            </beans:list>
        </beans:constructor-arg>
    </beans:bean>
```
3.11 resource-server配置, 这儿定义两咱不同的resource
[html] view plain copy print ?
1. 
2. <oauth2:resource-server id="unityResourceServer" resource-id="unity-resource" token-services-ref="tokenServices"/>
4. 
5. <oauth2:resource-server id="mobileResourceServer" resource-id="mobile-resource" token-services-ref="tokenServices"/>
```
    
    <oauth2:resource-server id="unityResourceServer" resource-id="unity-resource" token-services-ref="tokenServices"/>

    
    <oauth2:resource-server id="mobileResourceServer" resource-id="mobile-resource" token-services-ref="tokenServices"/>
```
注意: 每个resource-id的值必须在对应的ClientDetails中resourceIds值中存在

3.12 ClientCredentialsTokenEndpointFilter配置, 该Filter将作用于Spring Security的chain 链条中
[html] view plain copy print ?
1. <beans:bean id="clientCredentialsTokenEndpointFilter"
2. class="org.springframework.security.oauth2.provider.client.ClientCredentialsTokenEndpointFilter">
3. <beans:property name="authenticationManager" ref="oauth2AuthenticationManager"/>
4. </beans:bean>
```
    <beans:bean id="clientCredentialsTokenEndpointFilter"
                class="org.springframework.security.oauth2.provider.client.ClientCredentialsTokenEndpointFilter">
        <beans:property name="authenticationManager" ref="oauth2AuthenticationManager"/>
    </beans:bean>
```
3.13 /oauth/token 的http 配置, 用于监听该URL的请求, 核心
[html] view plain copy print ?
1. <http pattern="/oauth/token" create-session="stateless" authentication-manager-ref="oauth2AuthenticationManager"
2. entry-point-ref="oauth2AuthenticationEntryPoint">
3. <intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_FULLY"/>
4. <anonymous enabled="false"/>
5. <http-basic entry-point-ref="oauth2AuthenticationEntryPoint"/>
7. <custom-filter ref="clientCredentialsTokenEndpointFilter" before="BASIC_AUTH_FILTER"/>
8. <access-denied-handler ref="oauth2AccessDeniedHandler"/>
9. </http>
```
    <http pattern="/oauth/token" create-session="stateless" authentication-manager-ref="oauth2AuthenticationManager"
          entry-point-ref="oauth2AuthenticationEntryPoint">
        <intercept-url pattern="/oauth/token" access="IS_AUTHENTICATED_FULLY"/>
        <anonymous enabled="false"/>
        <http-basic entry-point-ref="oauth2AuthenticationEntryPoint"/>

        <custom-filter ref="clientCredentialsTokenEndpointFilter" before="BASIC_AUTH_FILTER"/>
        <access-denied-handler ref="oauth2AccessDeniedHandler"/>
    </http>
```
3.14 针对不同resource的http配置, 由于上面配置了两个resource, 这儿也配置两个
[html] view plain copy print ?
1. 
2. <http pattern="/unity/**" create-session="never" entry-point-ref="oauth2AuthenticationEntryPoint"
3. access-decision-manager-ref="oauth2AccessDecisionManager">
4. <anonymous enabled="false"/>
6. <intercept-url pattern="/unity/**" access="ROLE_UNITY,SCOPE_READ"/>
8. <custom-filter ref="unityResourceServer" before="PRE_AUTH_FILTER"/>
9. <access-denied-handler ref="oauth2AccessDeniedHandler"/>
10. </http>
12. 
13. <http pattern="/m/**" create-session="never" entry-point-ref="oauth2AuthenticationEntryPoint"
14. access-decision-manager-ref="oauth2AccessDecisionManager">
15. <anonymous enabled="false"/>
17. <intercept-url pattern="/m/**" access="ROLE_MOBILE,SCOPE_READ"/>
19. <custom-filter ref="mobileResourceServer" before="PRE_AUTH_FILTER"/>
20. <access-denied-handler ref="oauth2AccessDeniedHandler"/>
21. </http>
```
    
    <http pattern="/unity/**" create-session="never" entry-point-ref="oauth2AuthenticationEntryPoint"
          access-decision-manager-ref="oauth2AccessDecisionManager">
        <anonymous enabled="false"/>

        <intercept-url pattern="/unity/**" access="ROLE_UNITY,SCOPE_READ"/>

        <custom-filter ref="unityResourceServer" before="PRE_AUTH_FILTER"/>
        <access-denied-handler ref="oauth2AccessDeniedHandler"/>
    </http>

    
    <http pattern="/m/**" create-session="never" entry-point-ref="oauth2AuthenticationEntryPoint"
          access-decision-manager-ref="oauth2AccessDecisionManager">
        <anonymous enabled="false"/>

        <intercept-url pattern="/m/**" access="ROLE_MOBILE,SCOPE_READ"/>

        <custom-filter ref="mobileResourceServer" before="PRE_AUTH_FILTER"/>
        <access-denied-handler ref="oauth2AccessDeniedHandler"/>
    </http>
```
注意每一个http对应不同的resourceServer. access-decison-manager-ref对应Oauth的AccessDecisionManager

3.15 默认的http配置,给/oauth/** 设置权限
[html] view plain copy print ?
1. <http access-denied-page="/login.jsp?authorization_error=2" disable-url-rewriting="true"
2. authentication-manager-ref="authenticationManager">
3. <intercept-url pattern="/oauth/**" access="ROLE_USER,ROLE_UNITY,ROLE_MOBILE"/>
4. <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
6. <form-login authentication-failure-url="/login.jsp?authentication_error=1" default-target-url="/index.jsp"
7. login-page="/login.jsp" login-processing-url="/login.do"/>
8. <logout logout-success-url="/index.jsp" logout-url="/logout.do"/>
9. <anonymous/>
10. </http>
```
    <http access-denied-page="/login.jsp?authorization_error=2" disable-url-rewriting="true"
          authentication-manager-ref="authenticationManager">
        <intercept-url pattern="/oauth/**" access="ROLE_USER,ROLE_UNITY,ROLE_MOBILE"/>
        <intercept-url pattern="/**" access="IS_AUTHENTICATED_ANONYMOUSLY"/>

        <form-login authentication-failure-url="/login.jsp?authentication_error=1" default-target-url="/index.jsp"
                    login-page="/login.jsp" login-processing-url="/login.do"/>
        <logout logout-success-url="/index.jsp" logout-url="/logout.do"/>
        <anonymous/>
    </http>
```
到此, securiy.xml 配置完毕.

当然,还有些额外的工作你需要做, 如配置dataSource, 创建数据库, 添加用户用户信息, 管理ClientDetails等等.

Oauth相关的数据都是存放在数据库, 我们就可以根据表结果创建domain来实现管理.

为了方便大家学习与讨论, 我现在把该项目放在了GIT OSC上, 访问地址: http://git.oschina.net/shengzhao/spring-oauth-server, 欢迎大家关注.
