Question

我开发了一个完全在localhost上运行的grails 2.3.5应用程序，但在部署到我的Tomcat 7服务器时，出现以下错误：

Error 500: Internal Server Error

  URI
/schedulingAPI-0.1/tests
  Class
org.codehaus.groovy.runtime.typehandling.GroovyCastException
  Message
Cannot cast object 'org.hibernate.impl.SessionFactoryImpl@5ac08512' with class 'org.hibernate.impl.SessionFactoryImpl' to class 'org.codehaus.groovy.grails.orm.hibernate.SessionFactoryProxy'

跟踪：

我唯一的线索是这与springsecurity插件有关。

修改这是我的mp.ra.SchedulingService中发生错误的代码fragemtn：

def parseXML() {
    LessonParser par = new LessonParser(sessionFactory:sessionFactory)
    //par.parse(["src/data/tweede/"])
    par.parse(["src/data/access/","src/data/tweede/"])
}

这是我的LessonParser类：

package mp.data.parser


import javax.xml.parsers.SAXParser
import groovy.io.FileType
import javax.xml.parsers.SAXParserFactory
import mp.ra.*
import org.codehaus.groovy.grails.orm.hibernate.SessionFactoryProxy
import org.xml.sax.InputSource

class LessonParser {

    SessionFactoryProxy sessionFactory

    public void parse(baseFileLocations){

        SAXParserFactory factory = SAXParserFactory.newInstance();
        SAXParser saxParser = factory.newSAXParser();

        //alle directories overlopen
        baseFileLocations.each(){ location ->
            def dir = new File(location)

            //alle bestanden van directory inlezen
            dir.eachFile(){ file ->

                if (file.name.endsWith(".xml")) {
//                  print file.name
                    //alle bestanden parsen
                    InputStream inputStream = new FileInputStream(file);
                    Reader reader = new InputStreamReader(inputStream, "UTF-8");
                    InputSource is = new InputSource(reader);
                    is.setEncoding("UTF-8")

                    LessonHandler handler = new LessonHandler(sessionFactory)

                    saxParser.parse(is, handler);
                }

            }
        }
    }
}

我使用SesionFactory的原因是为了减少读取XML文件的时间。如果不使用SessionFactory，这需要大约20分钟，而使用SessionFactory需要几分钟。

仅在Tomcat 7服务器上部署grails应用程序时出现Hibernate错误
