我正在将grails应用程序从2.1.1升级到2.4.3,并且在升级过程中解决错误是一个永无止境的故事.

现在我陷入了困境.

任何想法如何解决这个问题？

谢谢!

为什么这个bat文件中的SET JAVA_HOME没有覆盖环境变量JAVA_HOME？

someFile.bat

@ECHO OFF
SET JAVA_HOME = Progra~2\Java\jdk1.6.0_23
echo JAVA_HOME: %JAVA_HOME%

OUTPUT

JAVA_HOME: C:\Program Files (x86)\Java\jdk1.7.0_21

这两个文件之间的实际区别是什么,groovy-all-2.2.1.jar并且groovy-all-2.2.1-indy.jar在GROOVY_HOME\embeddable目录中可用？

到目前为止我还没有使用过indy文件,我很想知道它的用途.

谢谢!

this query will retrieve all records during last 7 days.

SELECT * FROM STATISTICS WHERE TIMESTAMP > DATEADD('DAY',-7, NOW())

How can I change the query to include the records from midnight 7 days ago?

ex.

SELECT DATEADD('DAY',-7, NOW())

Gives: 2013-09-25 13:46:54.372

But I would like to have: 2013-09-25 00:00:00.000

我不明白为什么这段代码无法从xml字符串中获取特定节点。下面的代码将引发此错误：groovy.util.slurpersupport.NodeChildren.attributes（）适用于参数类型：（）值：[]

感谢您提供任何解决方法的解释！

def xml ='''<ProcessDefinition>
    <activity name="MergeLogData">
        <inputBindings>
            <SubmitLogMsgRequest>
                <MsgLevel>
                    <value-of select="$Start/SubmitLogMsgRequest/MsgLevel"/>
                </MsgLevel>
                <for-each select="SubmitLogMsgRequest/LogMsg">

            </SubmitLogMsgRequest>
        </inputBindings>
    </activity>

groovy.util.slurpersupport.GPathResult Process  = new XmlSlurper().parseText(xml) 

Process.depthFirst().grep { it.name()=="activity" && it.@name=="MergeLogData"}.each{activity->
   traverse(activity.inputBindings) // why is it not possible to point to the sub node "inputBindings" here ??
   //traverse(activity) this would work, but its pointing to the wrong node, I want it to be "inputBindings"
}

public void traverse(node) { …

这段代码有什么问题,它应该信任所有主机,但它不会...

它适用于例如google.com,但没有在我的机器上本地运行的API网关服务,为什么？

由于某些未知原因,此代码会抛出Unparseable日期异常

任何想法如何解决这个问题？

谢谢!

Date result =  df.parse(dateString);
System.out.println(result);

如何查看编译的jar文件将使用哪些java版本？

谢谢

我想将在当前时间列中存储为纳秒的日期进行比较，以仅获取不到 60 分钟的记录。

任何想法如何做到这一点？

也许它可能以某种方式使用 now() 函数。

谢谢！
