ibatis操作oracle的clob字段和blob字段

下载ibatis(2.16)以前的版本不行下载驱动(oracle10g)以前的版本好象也不行所用oracle版本9i创建表create table clobtable(id int,content clob);TestClob.java源码
import java.io.Reader;
import java.util.List;
import com.ibatis.common.resources.Resources;
import com.ibatis.sqlmap.client.SqlMapClient;
import com.ibatis.sqlmap.client.SqlMapClientBuilder;public class TestClob {

public static void main(String [] args) throws Exception
{

String resource="sql-map-config.xml";
Reader reader;
reader=Resources.getResourceAsReader(resource);
SqlMapClient sqlmap = SqlMapClientBuilder.buildSqlMapClient(reader);
Clobtable clob=new Clobtable();
StringBuffer value=new StringBuffer("");
for(int i=0;i<20000;i++)
{
value.append("bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb");
}
value.append("");
clob.setContent(value.toString());
clob.setId(2);
sqlmap.insert("insertClobtable",clob);
sqlmap.update("updateClobtable",clob);
Clobtable clob1=new Clobtable();
List list=sqlmap.queryForList("selectClobtable",clob1);
for(int i=0;i<list.size();i++)
{
clob1=(Clobtable)list.get(i);
System.out.println(new String(clob1.getContent()).length());
}
}}
Clobtable.java
public class Clobtable {
private int id;
private String content;

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}

public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}

blob操作只须把content的类型从String改成byte[ ]
