楔子

使用spring jdbcTemplate 查询数据 封装list报错

public List<SysRole> getUserByUserID(String uid) {
    if (StringUtils.isEmpty(uid)) {
        return null;
    }
    String sql = "SELECT  t.* from `sys_role` t ,`sys_role_user` ru WHERE ru.rid=t.id AND ru.uid=?";
    String[] param = { uid };
    List<SysRole> query = jdbcTemplate.query(sql, param, new BeanPropertyRowMapper(SysRole.class));
    // List<SysRole> query = jdbcTemplate.queryForList(sql, param, SysRole.class);
    return query;
}

参考于 博客
我是用的spring 版本是 4.3.10.RELEASE
博客中使用的类或许已经被替换了 ，固使用new BeanPropertyRowMapper(SysRole.class)
