dom解析器中的java.lang.StackOverflowError

以下是將由我的應用程序中的許多線程訪問的方法。dom解析器中的java.lang.StackOverflowError

public static String getXMLAsString(org.dom4j.Document dom4jDocument) 
    { 

     String strXML=""; 
     try { 
      strXML = dom4jDocument.asXML();    

      } 
      catch(Exception e){ 
      e.printStackTrace(); 
      System.out.println("XMLUtility : General Exception :- "+e.getMessage()); 
     }  

     return strXML; 
    }

成功執行某個線程後，會出現以下錯誤。

java.lang.StackOverflowError 
    at java.lang.String.indexOf(String.java:1352) 
    at org.apache.xerces.dom.ElementNSImpl.getPrefix(Unknown Source) 
    at org.dom4j.io.DOMReader.readElement(DOMReader.java:169) 
    ......................................................... 
    .........................................................

以下是上定義的方法的成功執行線程結果

你的數據看起來像什麼？它是乾淨的和有效的XML？ – 2012-01-17 16:02:25

看起來像一個無限遞歸循環，不知道是什麼原因... – esaj 2012-01-17 16:05:26

添加到邁克爾的評論，嘗試發佈樣品xml作爲這個代碼的輸入，如果可能的話在這裏發佈。 – kosa 2012-01-17 16:06:24

這可能只是你的XML文檔是如此之大，試圖讓這一切變成一個字符串使得chanined很多方法調用和堆棧內存變滿。嘗試通過分配更多的堆棧內存：

-Xss10m

JVM參數

（如果從Eclipse中執行：右鍵單擊項目 - >運行方式 - >運行配置 - >參數選項卡 - > VM參數 - > -Xss1m）

只要記住，它是每個線程10兆... – 2012-01-17 17:58:37

Myjbosss不與堆棧大小10米工作，所以我已經設置6米，但仍然面臨同樣的錯誤。 – chetan 2012-01-19 10:01:58
