package com.m;

import java.io.Writer;

import com.m.model.po.ACREPLY;

public class TestClob {

 public boolean insertClob() {
  ACREPLY ac = new ACREPLY();
  try {
   ac.setActiv_id(new Long(12));
   ac.setAreply_id(new Long(23));
   ac.setReply_content(Hibernate.createClob(" "));

   DbUtils.getDao().insert(ac);

   String content = "aaaaaaaaaaaaaaa";

   SerializableClob sclob = (SerializableClob) ac.getReply_content();

   java.sql.Clob jclob = sclob.getWrappedClob();

   oracle.sql.CLOB clob = (oracle.sql.CLOB) jclob;

   Writer out = clob.getCharacterOutputStream();

   out.write(content);

   out.close();

  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  return false;
 }

 public static void main(String[] agrs) {
  TestClob tc = new TestClob();
  tc.insertClob();
 }

}

到oracle.sql.CLOB clob = (oracle.sql.CLOB) jclob;步的时候出现了

org.hibernate.lob.ClobImpl cannot be cast to oracle.sql.CLOB
 at com.mender.TestClob.insertClob(TestClob.java:28)
 at com.mender.TestClob.main(TestClob.java:45)错误
