To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

这是userDaoImpl：

public class UserDaoImpl   implements UserDao {
	public DataSource dataSource;
	public  JdbcTemplate jdbcTemplate;
	public void setJdbcTemplate(DataSource dataSource) {
		this.jdbcTemplate = new JdbcTemplate(dataSource);
	}
	/**
	 * 根据用户名查询用户
	 * @param uname
	 * @return
	 */
	public User  getUserByUserName(String uname){
		String sql="select * from user where username=?";
		SqlParameter []param={
				new SqlParameter(uname,java.sql.Types.VARCHAR)
		};
		User user=jdbcTemplate.queryForObject(sql, param, new UserRowMapper());
		return user;
	}
