架构师之路-如何构建rest接口的安全性访问（dubbox+oatuh2+rest）

建立oauth2认证需要的数据库及数据表结构

>>前提:  使用Maven来管理项目; spring-security-oauth的版本号为 2.0.10.RELEASE

1. 添加Maven dependencies; 以下只列出了主要的

<dependency>  

    <groupId>org.springframework.securitygroupId>  

    <artifactId>spring-security-coreartifactId>  

    <version>${spring.security.version}version>  

dependency>

    <artifactId>spring-security-taglibsartifactId>  

    <artifactId>spring-security-aclartifactId>  

    <artifactId>spring-security-cryptoartifactId>  

    <artifactId>spring-security-configartifactId>  

    <groupId>org.springframework.security.oauthgroupId>  

    <artifactId>spring-security-oauth2artifactId>  

    <version>1.0.5.RELEASEversion>  

2. web.xml配置; 这一步与只使用Spring Security的配置一样.

    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.JdbcTokenStore">  

    <beans:constructor-arg index="0" ref="dataSource"/>  

beans:bean>  

  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"/>  

      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">  

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"/>  

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>  

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">  

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>  

3.11 resource-server配置, 这儿定义两咱不同的resource

<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

<beans:bean id="clientCredentialsTokenEndpointFilter"  

            class="org.springframework.security.oauth2.provider.client.ClientCredentialsTokenEndpointFilter">  

    <beans:property name="authenticationManager" ref="oauth2AuthenticationManager"/>  

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

<http pattern="/unity/**" create-session="never" entry-point-ref="oauth2AuthenticationEntryPoint"  

      access-decision-manager-ref="oauth2AccessDecisionManager">  

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

    <custom-filter ref="unityResourceServer" before="PRE_AUTH_FILTER"/>  

<http pattern="/m/**" create-session="never" entry-point-ref="oauth2AuthenticationEntryPoint"  

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

    <custom-filter ref="mobileResourceServer" before="PRE_AUTH_FILTER"/>  

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/>  

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.
