Question

我正在玩一些日期并使用jdbctemplate查询，我收到以下错误。

// creating a LocalDate object with specific date & time   

LocalDate date = LocalDate.of(LocalDate.now().getYear(), LocalDate.now().getMonth(), LocalDate.now().getDayOfMonth());

System.out.println("date $$$$$$$$$$$" +date);

LocalDateTime datetime = date.atTime(LocalTime.MAX);
System.out.println("datetime " +datetime);

// is not required since above steps is the same. 
datetime.withHour(23).withMinute(59).withSecond(59);

System.out.println("datetime with " +datetime);
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd hh24:mm:ss");
System.out.println("formatter" +datetime.format(formatter));


 return jdbcTemplate.queryForObject("SELECT COUNT(*) FROM test where status in ('ACTIVE','ACTIVE_P') AND CREATED<TO_dATE('"+datetime.format(formatter)+"','yyyy-MM-dd hh24:mm:ss')",Integer.class);

这是输出

date $$$$$$$$$$$2017-08-20
datetime 2017-08-20T23:59:59.999999999
datetime with 2017-08-20T23:59:59.999999999

有人能让我知道我哪里错了。我在日志中看到查询打印为

AND CREATED<TO_dATE('2017-08-20 1124:59:59','yyyy-MM-dd hh24:mm:ss')

1124，我认为这是问题，但无论我做什么，我都无法删除那个。

Answer 1

1）您必须更改：mm：to：mi：格式为掩码：

SELECT TO_DATE('2017-08-20 23:59:59','yyyy-MM-dd hh24:mi:ss') FROM DUAL

2）之后你必须编辑你的小时部分。

Answer 2

使用HH在Java中格式化24小时，使用：

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

ORA-01810：格式代码出现两次：jdbctemplate
