Exception in thread "main" org.springframework.jdbc.BadSqlGrammarException:

Exception in thread "main" org.springframework.jdbc.BadSqlGrammarException:
PreparedStatementCallback; bad SQL grammar [update  person set name=? where age=?];
nested exception is java.sql.SQLException: ORA-00900: 无效 SQL 语句
错误原因：
用错方法：

int row=jt.queryForList(sql2,values2);

正确代码：

int row=jt.update(sql2,values2);

原代码：

package test;

import java.math.BigDecimal;
import java.util.Iterator;
import java.util.List;
import java.util.Map;

import javax.sql.DataSource;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;

import entity.Person;

public class TestJdbcTemplate {
public static void main(String[] args) {
	ApplicationContext context=new ClassPathXmlApplicationContext("applicationContext.xml");
	DataSource dataSource=(DataSource) context.getBean("dataSource");
	JdbcTemplate jt=new JdbcTemplate(dataSource);
	
	//查询sql语句
	String sql="select * from person where name=? and age=?";
	//执行带有参数的查询语句
	Object[] values={"张三",23};
	List result=jt.queryForList(sql,values);
	
	Iterator it=result.iterator();
	while(it.hasNext()){
		System.out.println((Map)it.next());
		
	}
	//更新语句：
	String sql2="update person set name= ? where age= ?";
	Object[] values2={"zhangxiaosan",30};
	//错误语句
        //int row=jt.queryForList(sql2,values2);
	int row=jt.update(sql2,values2);
	System.out.println("受影响的行数"+row);
	
	//执行DDL语句
	jt.execute("create table Test(test varchar(200))");
	System.out.println("建表完毕");
}
