jdbcTemplate 报空指针

@Autowired
protected JdbcTemplate jdbcTemplate;

public int getRecordCount(String sql, String... args) throws Exception {
    return jdbcTemplate.queryForObject(sql, args, Integer.class);
}

public int getRecordCount(String sql, Object[] args) throws Exception {
    return jdbcTemplate.queryForObject(sql, args, Integer.class);
}

jdbcTemplate自动注解，没注解成功
