关于Java调用Oracle出现乱码的问题.(字符集为AMEROCAN_AMERICA.US7ASCII)

[getdown]

我的Oracle服务器端字符集为AMEROCAN_AMERICA.US7ASCII,这个是已经存在的运行数据库,数据库的字符集已经不能改变.
请问JDBC连接这种字符集的情况下,Java调用端的JVM或者JDBC的链接怎么设置,才能保证存入的和取出的都不会乱码.

int oracleId = oracle.sql.CharacterSet.UTF8_CHARSET;
oracle.sql.CharacterSet mycharset = oracle.sql.CharacterSet.make(oracleId);

写全了
CREATE TYPE num_varray AS VARRAY(10) OF VARCHAR2(12)
/
CREATE TABLE varray_table (col1 num_varray);
INSERT INTO varray_table VALUES (num_varray('你好', 'abc'));

select * from varray_table;

import java.sql.*;
import java.math.*;
import oracle.jdbc.driver.*;
import oracle.sql.*;

class Array1
{

public static void main(String args[]) throws Exception
{
int oracleId = CharacterSet.ZHS16GBK_CHARSET;
CharacterSet dbCharset = CharacterSet.make(oracleId);

DriverManager.registerDriver
(new oracle.jdbc.driver.OracleDriver());

Connection conn =
DriverManager.getConnection
("jdbc:oracle:thin:@10.9.200.58:1521:db01",
"mytest",
"mytest");

Statement stmt = conn.createStatement();

ResultSet rs = stmt.executeQuery("SELECT * FROM varray_table");

while (rs.next()) {
ARRAY my_array = ((OracleResultSet)rs).getARRAY(1);

// return the SQL type names, integer codes,
// and lengths of the columns
System.out.println ("Array is of type " + my_array.getSQLTypeName());
System.out.println ("Array element is of typecode " + my_array.getBaseType());
System.out.println ("Array is of length " + my_array.length());

// get Array elements
String[] values = (String[]) my_array.getArray();
for (int i = 0; i < values.length; i++)
{
oracle.sql.CHAR out_value = new oracle.sql.CHAR(values[i], dbCharset);
System.out.println(">> index " + i + " = " + out_value);
}


}

rs.close();
stmt.close();
conn.close();
}
}

主要是这个包oracle.sql.*;oracle官方网站上有的下

我是用hibernate作为O/R mapping访问数据库,所以上述方式在hibernate访问数据库的情况下不大可行啊.有没有什么简便的方法在hibernate里面设置?

[cenlmmx]

<property name="hibernate.connection.url">
jdbc:oracle:thin:@10.110.1.12:1521:ORA9
</property>
<property name="hibernate.connection.driver_class">
oracle.jdbc.driver.OracleDriver
</property>
<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">UTF-8</property>
<!--<property name="hibernate.connection.defaultNChar">true</property>-->
<property name="hibernate.connection.username">user</property>
<property name="hibernate.connection.password">123456</property>
<!-- property name="hibernate.connection.pool_size"></property -->
<!-- dialect for Oracle 9 -->
<property name="dialect">
net.sf.hibernate.dialect.Oracle9Dialect
</property>

这样好像也不行啊....

[getdown]

cenlmmx(学海无涯苦作舟),你有试过酱紫可行吗
<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">UTF-8</property>
针对Oracle好像不起作用..

可以考虑在get set 方法里面加进去装码的代码, 而实体的get set方法可以用代码生成器自动生成.
