  最近想做個簡單的extjs5的登入跳轉，之前做了一個，但是extjs又沒有跳轉連結，每次重新整理都需要重新登入，實現的不好，現在想實現登入使用者的認證，於是看到了shiro這個架構，看起來還是比較好用的，於是開始研究。

  剛開始搭建，發現官網給的hello world程式需要maven支援對pom檔案研究又不深入，只能拋棄這種方式了。自己安裝官方參考手冊，下載了quickstart檔案源碼，但是這是maven檔案，不會用，只能手動的建立了一個檔案這樣的，啟動並執行時候報了好多錯誤，跑了好久，終於把hello world給運行出來了，現在分享一下可以啟動並執行程式的建立的整個過程：

1.使用eclipse/myeclipse建立shirodemo工程

2.建立lib檔案夾，將shiro-all-1.1.0.jar、slf4j-api-1.7.7.jar、slf4j-log4j12-1.7.7.jar、log4j-1.2.16.jar這些jar包添加進來。

3.build path---config build path將這些jar包添加到libraries中

4.建立自己的程式包，例如我建立com.susheng包，將quickstart中Quickstart.java中代碼複製一份來。

5.添加shiro.ini和log4j.properties檔案到src目錄下。

6.運行程式：

程式正常運行。

之前遇到錯誤清單：

1.沒有添加shiro.ini檔案

錯誤資訊：Exception in thread "main" org.apache.shiro.config.ConfigurationException: java.io.IOException: Resource [classpath:shiro.ini] could not be found.

原因是沒有添加shiro.ini檔案，解決方案，將shiro.ini放在src目錄下即可解決。

2.沒有正確添加self4j-log4j12.jar包

錯誤資訊：SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

self4j的包沒有添加完成，這個問題真是弄得我好久都鬱悶著。看執行個體代碼，我引入slf4j-api-1.7.7.jar包之後，都可以正常些代碼，沒有錯誤提示了，但是居然這個jar包還依賴其他jar包才可以，這相當讓我不舒服啊。引入其他self4j的jar包（slf4j-log4j12-1.7.7.jar）即可解決。

3.沒有引入log4j的jar包

錯誤資訊： java.lang.NoClassDefFoundError: org/apache/log4j/Level

4.沒有log4j的設定檔

錯誤資訊：log4j:WARN No appenders could be found for logger (org.apache.shiro.io.ResourceUtils).

添加log4j.properties到src目錄下即可解決問題。

最終的程式目錄結構如下：

代碼都是shiro例子的，也粘貼一下吧。
