采用得是Oracle9i数据库，Jboss或Weblogic。
JDBC采用ORACLE9i自带的Class12.jar
－－－－－－－－－－－－－
数据库结构：
代码:
CREATE TABLE SNCPARAMETERS
(
ID NUMBER(19) NOT NULL,
SNCID NUMBER(19),
NAME VARCHAR2(255),
VALUE CLOB
)
－－－－－－－－－－－－－－
BO采用xdoclet建立的：
代码:
public class SNCParameters extends BaseObject
{
/**
* Returns the id.
*
* @return long
* @hibernate.id
* column = "id"
* type = "long"
* generator-class = "native"
* unsaved-value = "null"
*/
public Long getId()
{
return id;
}
/**
* Sets the Id attribute of the SNCParameters object
*
* @param id The new Id value
*/
public void setId(Long id)
{
this.id = id;
}
/**
* Returns the name.
*
* @return String
*
* @hibernate.property
* column = "name"
* type = "string"
* not-null = "true"
* unique = "false"
*/
public String getName()
{
return name;
}
/**
* Sets the Name attribute of the SNCParameters object
*
* @param name The new Name value
*/
public void setName(String name)
{
this.name = name;
}
/**
* Returns the sncId.
*
* @return Long
*
* @hibernate.property
* column = "sncId"
* type = "long"
* not-null = "true"
* unique = "false"
*/
public Long getSncId()
{
return sncId;
}
/**
* Sets the SncId attribute of the SNCParameters object
*
* @param sncId The new SncId value
*/
public void setSncId(Long sncId)
{
this.sncId = sncId;
}
/**
* Returns the values.
*
* @return Clob
*
* @hibernate.property
* column = "value"
* type = "clob"
* not-null = "true"
* unique = "false"
*/
public Clob getValue()
{
return value;
}
/**
* Sets the Values attribute of the SNCParameters object
*
* @param values The new Values value
*/
public void setValue(Clob value)
{
this.value = value;
}
private Long id;
private Long sncId;
private String name;
private Clob value;
private String valueString;
public String getValueString()
{
return valueString;
}
public void setValueString(String valueString)
{
this.valueString = valueString;
}
}
注：valueString并不映射到数据库的CLOB字段，只是方便需要使用这个BO的人用GET、SET 处理这个巨长的CLOB字段

xdocLet生成的XML文件：
代码:
<?xml version="1.0"?>

insert的代码：
代码:
public List batchAddSncParameters(List sncParametersList, Long sncId) throws DbAccessException
{
logger.enterMethod();
List ret = new ArrayList();
try
