注意配置文件头加了两条：spring-tx-3.0.xsd和xmlns:tx

package service;

import com.NiutDAO;
import service.interfac.ILoginService;

public class LoginServiceImpl implements ILoginService {
    @Resource
    private JdbcTemplate jt;
  
    NiutDAO niutDAO;
    public void setNiutDAO(NiutDAO niutDAO) {
        this.niutDAO = niutDAO;
    }
    public void login() {
        updateRegister(15,1);
        System.out.println("successfully update 1");
        updateRegisterWrong(19,2);
        System.out.println("successfully update 2");

    }  
    public void updateRegister(int age,int id) {
        String sql = "UPDATE register SET age=? WHERE id=?";
        Object params[] = new Object[] { new Integer(age),
                 new Integer(id) };
        int type[] = new int[] { Types.INTEGER , Types.INTEGER };
        jt.update(sql, params, type);
    }
    public void updateRegisterWrong(int age,int id) {
        String sql = "UPDATE register SET age=? WWWWWWW id=?";
        Object params[] = new Object[] { new Integer(age),
                new Integer(id) };
        int type[] = new int[] { Types.INTEGER , Types.INTEGER };
        jt.update(sql, params, type);
    }
}


即使updateRegister(15,1);成功执行，但数据库中结果并没有被更新，因为updateRegisterWrong(19,2);的错误致使updateRegister(15,1);的结果发生了回滚。

输出结果：
successfully update 1
严重: Servlet.service() for servlet spring threw exception
java.sql.SQLException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WWWWWWW id=2' at line 1
