NumberFormatException尝试在grails中进行日期搜索时的输入字符串

Question

我从gsp视图中获取了一个包含日期和时间的字符串：

def name = params.name
def time = params.minutes
def date = params.datapicker

现在，我希望按日期和名称在我的域中进行搜索。所以，我加入日期和时间进行搜索：

def dataSearch = date + " " + time
MyDomain result= MyDomain.findByNameAndDateCreatedGreaterThan(name, dataSearch)

但是，我收到了这个错误：

2016-05-26 09:56:44,488 [http-bio-8090-exec-3] ERROR errors.GrailsExceptionResolver  - NumberFormatException occurred when processing request: [POST] /myClass/search- parameters:

minutes: 18:17:42
button: search
datapicker: 2016-04-28
For input string: "2016-04-28 18:17:42". Stacktrace follows:

Answer 1

将String转换为Date，然后再将其传递给findByNameAndDateCreatedGreaterThan，例如

def dataSearch = date + " " + time
Date date = Date.parse('yyyy-MM-dd HH:mm:ss', dataSearch)
MyDomain result = MyDomain.findByNameAndDateCreatedGreaterThan(name, date)
