dom解析器中的java.lang.StackOverflower错误

dom解析器中的java.lang.StackOverflower错误,java,stack-overflow,dom4j,Java,Stack Overflow,Dom4j,下面是我的应用程序中许多线程将访问的方法 public static String getXMLAsString(org.dom4j.Document dom4jDocument) { String strXML=""; try { strXML = dom4jDocument.asXML(); } catch(Exception e){

下面是我的应用程序中许多线程将访问的方法

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;
    }
在成功执行某个线程后,它将给出以下错误

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)

以下是成功执行的线程的上限定义方法的结果

可能只是因为您的XML文档太大,试图将其全部放在一个字符串中会导致大量的更改方法调用,堆栈内存也会满。尝试通过以下方式分配更多堆栈内存:

-Xss10m
JVM参数


(如果从Eclipse执行:右键单击项目->运行方式…->运行配置->参数选项卡->虚拟机参数->-Xss1m)

您的数据是什么样子的?它是干净且有效的xml吗?看起来像一个无限递归循环,但不知道是什么导致它…添加到Michael comment中,尝试发布您获得的示例xml作为此代码的输入,如果可能的话,发布在这里。如果dom4j允许,我会感到惊讶,但是,当元素是它自己的祖先时,您还没有创建XML文档吗?您应该尝试调试代码,以查看异常发生时堆栈跟踪的外观。如果有相同的方法调用序列重复的模式,那么看看XML解析器库正在尝试做什么可能会有所帮助。MyJBoss无法使用10m大小的堆栈,因此我设置了6m,但仍然面临相同的错误。
