hibernate 表字段大小写问题

初学hibernate，改写老的项目，由于老的项目表，字段都是大小写，网上看了别人一个贴继承改写ImprovedNamingStrategy
public class MPSNameingStrategy extends ImprovedNamingStrategy {
private static final long serialVersionUID = 1L;

@Override
public String classToTableName(String className) {
return className;
}

@Override
public String columnName(String columnName) {
return columnName;
}

@Override
public String tableName(String tableName) {
return tableName;
}

@Override
public String propertyToColumnName(String propertyName) {
return propertyName;
}

}
实体类
@Entity(name=Base_Product.TABLE_NAME)
//@Table(name=Base_Product.TABLE_NAME)
//@org.hibernate.annotations.Table(appliesTo = Base_Product.TABLE_NAME,comment="流程活动定义表")

public class Base_Product implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1774573695378068468L;
public static final String TABLE_NAME="\"Base_Product\"";
protected Long Product_Id;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE)//hibernate主键策略,使用hibernate，其他数据库大家参考hibernate参考
@Column(name="\"Product_Id\"")
public Long getProduct_Id() {
return Product_Id;
}
public void setProduct_Id(Long product_Id) {
Product_Id = product_Id;
}
@Column(name="\"Product_Code\"")
public String getProduct_Code() {
return Product_Code;
}
public void setProduct_Code(String product_Code) {
Product_Code = product_Code;
}
private String Product_Code;

}
修改hibernate配置文件<property name="namingStrategy">
<bean class="a.b.MPSNameingStrategy" />
</property
运行测试用例
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;

@ContextConfiguration(locations = { "classpath*:/applicationContext-test.xml" })
public class ProductTest  extends AbstractTransactionalJUnit4SpringContextTests {
@Autowired
private JdbcTemplate jdbcTemplate;
public NamedParameterJdbcTemplate getNPJdbc(){
return new NamedParameterJdbcTemplate(jdbcTemplate);
}
@Test
public void checkProduct()
{
HashMap<String,List> paramMap = new HashMap<String,List>();
List<String> list=new ArrayList<String>();
list.add("1");
list.add("2");
paramMap.put("list",list);
String sql = "select * from \"Base_Product\" t where t.\"Product_Code\" in (:list)";
List<Base_Product> mrs =this.getNPJdbc().query(sql,paramMap,BeanPropertyRowMapper.newInstance(Base_Product.class));
for(Base_Product bp:mrs){
System.out.println(bp.getProduct_Id());
}
}
}

生成表：
CREATE TABLE "Base_Product"
(
  "Product_Id"    NUMBER(19)                    NOT NULL,
  "Product_Code"  VARCHAR2(255 CHAR)
)
