Grails - java.sql.Date的非法参数 [英] Grails - illegal arguments for java.sql.Date

问题描述

我试图通过在当前日期创建一个Calendar对象来创建一个sql.Date。这使我疯狂，如果我将日期硬编码为一个字符串，那么每件事情都很好：

  def dat = java.sql。 Date.valueOf（ 2011-01-31）; 
  

但是，如果我在代码中创建相同的字符串，我会收到非法的参数错误。 p>

  def currentDay = {
 
 def today = Calendar.getInstance（）; 
 
 def dateYear = today.get（Calendar.YEAR）; 
 def dateMonth = today.get（Calendar.MONTH）+ 1; 
 def dateDay = today.get（Calendar.DATE）; 
 
 def todayDate =（dateYear + - + dateMonth + - + dateDay）; 
 def todayDateString = todayDate.toString（）; 
 def todayDate2 = java.sql.Date.valueOf（todayDateString）; 
 
 [today：todayDate2] 
} 
  

产生这个stacktrace：

  java.lang.IllegalArgumentException $ b $ java.sql.Date.valueOf（Date.java： 138）在java_sql_Date 
 $ valueOf.call（未知源）
 at samma.TapesController $ _closure7.doCall（TapesController.groovy：178）
 at samma.TapesController $ _closure7.doCall（TapesController。 groovy）
在java.lang.Thread.run（Thread.java:619）
  

我知道我在做一些完全愚蠢的事情，但我无法弄清楚什么，也没有什么解决办法。

谢谢

用

替换上面的所有代码

  def currentDay = {
 
 def todayDate = new java.sql.Date（new Date（）。time）
 todayDate.clearTime（）
 
 [today：todayDate] 
} 
  




I'm trying to create an sql.Date by creating a Calendar object on the current date. This is driving me crazy, if i hardcode the date as a string every thing is fine:

def dat = java.sql.Date.valueOf("2011-01-31");

But, if I create the same string in code I'm getting an illegal argument error.

def currentDay  = {

    def today = Calendar.getInstance();

    def dateYear = today.get(Calendar.YEAR);
    def dateMonth = today.get(Calendar.MONTH) + 1;
    def dateDay =today.get(Calendar.DATE);

    def todayDate = (dateYear + "-" + dateMonth + "-" + dateDay);
    def todayDateString = todayDate.toString();
    def todayDate2 = java.sql.Date.valueOf(todayDateString);

    [ today : todayDate2 ]
}

Running this is yielding this stacktrace:

java.lang.IllegalArgumentException
    at java.sql.Date.valueOf(Date.java:138)
    at java_sql_Date$valueOf.call(Unknown Source)
    at samma.TapesController$_closure7.doCall(TapesController.groovy:178)
    at samma.TapesController$_closure7.doCall(TapesController.groovy)
    at java.lang.Thread.run(Thread.java:619)

I know I'm doing something completely stupid, but I cannot figure out what, nor what a workaround could be.

Thanks

Donald.

解决方案

Replace all the code above with

def currentDay  = {

    def todayDate = new java.sql.Date(new Date().time)
    todayDate.clearTime()

    [today: todayDate]
}
