Oracle Access Manager(OAM)是oracle公司開發的身份認證和資源管理解決方案。結合WebGate
和OHS
可實現系統間單點登陸集成。html
oracle中間件產品能夠很是方便的與OAM進行集成,經過配置weblogic
安全域(Security Realms),應用幾乎不用作任何改動便可實現單點登陸。java
後臺接口開發中獲取當前登陸用戶是不可避免的一個步驟,spring boot也是如此,本文介紹spring boot與OAM集成的一個可行而且認爲是簡單的方案。git
要實現二者之間的集成須要解決兩個問題:github
只要實現以上兩點就能實現spring boot 在脫離weblogic的狀況下也能獲取用戶信息,若是可行,該方案適用於任何後端程序。web
在這裏能夠下載sdk,下載時請選擇對應的OAM版本,本文使用11.1.1.5.0
版本。spring
爲了使用方便,能夠將jar包安裝到本地maven倉庫segmentfault
mvn install:install-file -Dfile="/Users/asan/workspace/mpaas/lib/oamasdk-api.jar" -DgroupId=com.oracle -DartifactId=oamasdk-api -Dversion=11.1.1.5.0 -Dpackaging=jar
這樣能夠經過如下方式在pom中引用後端
<dependency> <groupId>com.oracle</groupId> <artifactId>oamasdk-api</artifactId> <version>11.1.1.5.0</version> </dependency>
登陸oamconsole(通常是http://host:7001/oamconsole),在歡迎界面建立一個新的OAM 11g Webgate
輸入Name
和Host Identifier
,這兩個默認同樣,必定要將Access Client Password
設置爲空,由於在實踐中,sdk沒法解析密碼,報錯信息以下api
2018-10-10 22:46:18 oracle.security.am.asdk.AccessClient initialize 嚴重: Oracle Access SDK 初始化失敗。 oracle.security.am.asdk.AccessException: OAMAGENT-02072: 沒法執行encrypt password操做。 at oracle.security.am.asdk.impl.Configuration.setEncryptedPassword(Configuration.java:321) at oracle.security.am.asdk.impl.ConfigXMLHandler.processConfig(ConfigXMLHandler.java:580) at oracle.security.am.asdk.impl.ConfigXMLHandler.readConfigurationFromFile(ConfigXMLHandler.java:126) at oracle.security.am.asdk.AccessClient.initialize(AccessClient.java:634) at oracle.security.am.asdk.AccessClient.<init>(AccessClient.java:553) at oracle.security.am.asdk.AccessClient.createDefaultInstance(AccessClient.java:242) ...
官方說是sdk版本問題,但筆者試過全部的sdk版本仍是沒法解決。瀏覽器
點擊右上角Apply
後能夠有系統提示,在提示路徑下能夠找到ObAccessClient.xml
文件,這個就是webgate的配置文件,在實際環境配置中,須要將該文件放到$OHS_HOME/config/webgate/config
目錄下,才能實現ohs資源攔截認證。
將ObAccessClient.xml
文件複製到本地,如放到目錄/you/path/config/ObAccessClient.xml
下。
直接上代碼
import oracle.security.am.asdk.AccessClient; import oracle.security.am.asdk.AccessException; import oracle.security.am.asdk.UserSession; public class OAM { //保存ObAccessClient.xml文件目錄 public static final String OAM_CONFIG_PATH = "/you/path/config/"; public static void main(String[] args) throws AccessException { String cookie = "Ad/NbCxwjXyRvO15xxJiueMY/utzybeifo6bIhhKOcsvQqQM73fIoE/fKm7zdUeo7FqbDYhP6ncFC/Ntq4yeSAXQeIum9EcaCqAXrUVyvO99ACxDv/2OdX5D/R10a7nuc6nlE54zPVbpm5xkp5H8TjlaM0oeqjDZXOalLcAsV9RnQjLrd9rW3cQi05PVuPalf0jRj+pqCILCHf+sO+cCdcYE2jEybbX3oXVwVGYJQSDDIEm/ne56gZlBKOg56zne2zEp60TkyXgkBG8vL0mNqVGdxd9DmNDeGaAYDoif5EzKfXp7K9QtWbGOjwRSGcTZcLvWcBPJjBhTOBGCLJ3yEg=="; AccessClient client = null; client = AccessClient.createDefaultInstance(OAM_CONFIG_PATH, AccessClient.CompatibilityMode.OAM_10G); UserSession session = new UserSession(cookie); String userName = session.getUserIdentity(); if (userName != null) { userName = userName.substring(userName.indexOf("uid=") + 4, userName.indexOf(",")); } System.out.println("current user==>" + userName); } }
cookie
能夠在瀏覽器上登陸系統,F12進入開發者面板,在網絡請求裏找到cookie,OAM cookie名稱爲OAMAuthnCookie
上面代碼只是一個demo,跟spring boot也沒什麼關係,在開發中,咱們通常都有個最佳實踐,下面介紹一個我認爲是較佳的實踐方案。在開始以前,建議你閱讀下這篇文章,瞭解一些規範,固然,你也能夠跳過,這個不是核心內容。
在demo裏有個稍微比較複雜的操做,就是從服務器下載ObAccessClient.xml
文件,而且保存到本地路徑,在代碼裏引用,並且查看ObAccessClient.xml
文件能夠知道里面的內容大部分能夠寫死,只有在建立webgate那個界面填的內容是動態的。所以能夠考慮將配置文件放入到spring boot的application.properties
中,而後在程序裏動態生成配置文件,避免引入新的配置文件。
application.properties
mpaas.sso.oam.host=xxxx.example.com mpaas.sso.oam.port=5575 mpaas.sso.oam.hostId=my_webgate_11g mpaas.sso.oam.id=my_webgate_11g mpaas.sso.oam.cookieName=OAMAuthnCookie

代碼能夠在github上下載查看
須要配置ohs反向代理,在ohs配置文件mod_wl_ohs.conf
最後添加如下配置項,並重啓ohs
... ProxyPass /test http://ip:8080/test
ip指向運行spring boot的機器ip
經過單點登陸地址訪問,會先跳轉到登陸頁面,登陸完後可訪問接口而且返回當前用戶信息
更好的作法是在filter中攔截請求作登陸認證,未經過認證的返回401
經過認證的將用戶信息保存在ThreadLocal
裏,這樣能夠在任意位置獲取用戶信息。這個就留給讀者自行實現。
