MySQL中TIMESTAMP类型返回日期时间数据中带有T的解决

@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
private Date updateTime;

@Configuration
public class WEBmvcConfig {
    @Bean
    MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        ObjectMapper mapper = new ObjectMapper();
        mapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
        converter.setObjectMapper(mapper);
        return converter;
    }
}

CREATE TABLE t (d date , t  time , dt datetime);

desc t

insert INTO t VALUES(NOW(),NOW(),NOW())

select * from t

CREATE TABLE ttt (t timestamp);

INSERT INTO ttt VALUES(NULL)

select * from ttt

alter TABLE ttt add t2 timestamp;

SHOW CREATE TABLE ttt;

CREATE TABLE `ttt` (
  `t` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `t2` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00'
) ENGINE=MyISAM DEFAULT CHARSET=utf8

INSERT INTO ttt VALUES(null,null)

update ttt set t2 = '2015-11-28 03:00:40' where t='2015-11-27 03:00:40'

alter TABLE ttt   change `t` `t` timestamp default '0000-00-00 00:00:00' NOT NULL ;
desc ttt

update ttt set t2 = '2015-11-28 04:00:40' where t='2015-11-27 03:02:50'
