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
<!--spring security-->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-core</artifactId>
<version>${spring.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>${spring.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-taglibs</artifactId>
<version>${spring.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-acl</artifactId>
<version>${spring.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-crypto</artifactId>
<version>${spring.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>${spring.security.version}</version>
</dependency>
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>1.0.5.RELEASE</version>
</dependency>
2. web.xml配置; 这一步与只使用Spring Security的配置一样.
</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>
<!--contextConfigLocation -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/*.xml</param-value>
</context-param>
<!-- Spring context listener -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--hy mvc-->
<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
<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
<!--<beans:bean id="tokenStore" class="org.springframework.security.oauth2.provider.token.InMemoryTokenStore"/>-->
<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
<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
<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
<beans:bean id="oauth2ClientDetailsUserService"
class="org.springframework.security.oauth2.provider.client.ClientDetailsUserDetailsService">
<beans:constructor-arg ref="clientDetailsService"/>
</beans:bean>
3.5 OAuth2AuthenticationEntryPoint配置
<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
<authentication-manager id="oauth2AuthenticationManager">
<authentication-provider user-service-ref="oauth2ClientDetailsUserService"/>
</authentication-manager>
第二个AuthenticationManager用于向获取UserDetails信息,
<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
<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
<beans:bean id="oauthUserApprovalHandler" class="org.springframework.security.oauth2.provider.approval.DefaultUserApprovalHandler">
</beans:bean>
3.9 authorization-server配置, 核心
<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
<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
<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
<!--unity resource server filter-->
<oauth2:resource-server id="unityResourceServer" resource-id="unity-resource" token-services-ref="tokenServices"/>
<!--mobile resource server filter-->
<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
<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
<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
<!--unity http configuration-->
<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>
<!--mobile http configuration-->
<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
<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.
