對JdbcTemplate再次簡單的一個封裝工具類

@Repository
public class JdbcTemplateRepository {

    private static final Logger logger = LoggerFactory.getLogger(JdbcTemplateRepository.class);

    @Autowired
    public JdbcTemplate jdbcTemplate;

    public <T> List<T> queryForList(String sql, Class<T> mappedClass){
        logger.info("sql: " + sql);
        List<T> resultList = jdbcTemplate.query(sql, new BeanPropertyRowMapper<>(mappedClass));
        logger.info("resultList: " + resultList);
        return resultList;
    }




}

 

測試如下：

        String sql = "SELECT " +
                "t1.id id, " +
                "t1.pid pid, " +
                "t1.menu_name menuName, " +
                "t2.menu_name parentName, " +
                "t1.menu_code menuCode, " +
                "t1.menu_type menuType, " +
                "t1.url url, " +
                "t1.icon icon, " +
                "t1.outside outside, " +
                "t1.create_time createTime, " +
                "t1.create_by createBy, " +
                "t1.update_time updateTime, " +
                "t1.update_by updateBy, " +
                "CASE WHEN t3.id IS NULL THEN 'false' ELSE 'true' END checked " +
                "FROM sys_menu t1 " +
                "LEFT JOIN sys_menu t2 ON t1.pid = t2.id " +
                "LEFT JOIN sys_role_menu t3 ON t1.id = t3. menu_id AND t3.role_id = 3 " +
                "ORDER BY id ";

        logger.info("sql: " + sql);
        List<SysMenu> sysMenuList = jdbcTemplateRepository.queryForList(sql, SysMenu.class);
        logger.info("sysMenuList: " + sysMenuList);
