java 通过jdbc得到sql结果集

  try {

           //
            DriverManagerDataSource dataSource=new DriverManagerDataSource();
            dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");
            dataSource.setUrl("jdbc:mysql://localhost:3306/job?characterEncoding=UTF-8&serverTimezone=Asia/Shanghai");
            dataSource.setUsername("root");
            dataSource.setPassword("root");

            JdbcTemplate jdbcTemplate=new JdbcTemplate(dataSource);
            List<Map<String,Object>> list = jdbcTemplate.queryForList(jobInfo.getCheckText());
            return list;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
