嚴重: Error filterStart

這個錯誤時在解決ssh框架，在斷網的情況下不能夠正常啟動的問題。之前用的struct2-2.1.6版本。啟動的時候老是報錯，錯誤內容如下方所示：

最後通過google和百度，發現導致該問題的主要可能有兩種原因：

1、struct2-2.1.6的bug;

2、struct2自身的相關jar的版本不一致（或者spring的jar不一致）；

對於網上的解決方案，是不可取

解決方法1，

這是由於struts-config.xml中的dtd校驗中的地址為 http://struts.apache.org/dtds/struts-config_1_2.dtd，按照這個地址將struts-config_1_2.dtd下載後放到和struts-config.xml同一資料夾下，然後將struts-config.xml中替換為struts-config_1_2.dtd就可以了

解決方法2，

struts-config.xml如下配置

<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">
.

ERROR [ActionServlet] Parsing error processing resource path
java.net.UnknownHostException: struts.apache.org

換了個頭

就好了

追問：

換這個標頭檔案的方式(另一種方法待試),不支援action呢.

最終的解決步驟：

1、將struct2的所引用的版本統一升級成struts-2.3.15.1。通過官網下載struts-2.3.15.1-all後，解壓開，將apps下的struts2-blank.war解壓出來拷貝struts2-blank\WEB-INF\lib所有檔案到專案的lib資料夾下；

2、統一調整spring到統一的版本2.5.3。注意要jar包包含的類要唯一，在很多情況下，有一個spring.jar包包含了所有spring的所需要的類庫。如果是從spring官網上下載的版本很可能是分散的。這是需要確保spring相關的jar要拷全。

3、對於標題上顯示的錯誤是由於沒有新增struts2-spring-plugin-2.3.15.1.jar所致。

4、如果專案中採用使用json格式返回資料，這需要新增struts2-json-plugin-2.3.15.1.jar、struts2-junit-plugin-2.3.15.1.jar兩個jar包。

這時斷網重啟tomcat系統已經能夠正常啟動了。

5、如果出現java.lang.NoSuchMethodError: antlr.collections.AST.getLine()錯誤，則可能是由於是用myeclipse自己導的包，出現了包版本衝突問題，問題出在struts包裡面有也有個antlr_XXX.jar,與hibernate包裡面的衝突了，hibernate的版本高 。因為Struts自帶的antlr-2.7.2.jar,比Hibernate3.3自帶的antlr-2.7.6.jar的版本要低，故要刪除前一個低版本的，struts1.3 和2.1都帶有antlr-2.7.2.jar，要把版本低的清除掉。 問題得到解決

上述的問題解決方案主要是針對我那個專案而言的，並非所有專案的解決方案。僅供大家參考。有問題可以直接在下面留言。
