运行Grails应用程序时出错.

我的应用程序在Grails 2.1.4中工作.

我在用

Groovy 2.1.*
Java 1.7
Tomcat 7.0.37

我将我的应用程序从Grails 2.1.4升级到2.3.0.M1.我收到这样的错误之后:

| Loading Grails 2.3.0.M1

我正在将我的应用程序从Grails 2.1迁移到2.3.迁移后我遇到了很多错误 - 我想要一些带有Grails 2.3和Spring集成的示例应用程序.

我做了一些HelloWorld示例应用程序,这些都运行正常.但即使我在我的应用程序中应用相同的东西,甚至在它给出错误的地方.因为我的应用程序非常大(100mb)并且我使用了很多与Spring,Hibernate和许多Grails插件的集成.

我没有找到任何类似于"从Grails 2.1迁移到Grails 2.3"的代码级文档.我无法从Grails或在线找到任何示例应用程序.

Grails官方文档,所有关于提供Grails META信息.

在我的main.gsp 229行:

<g:include controller="filter" action="tree"/>

我从https://github.com/grails-plugins/grails-spring-security-core获得了grails Spring安全示例应用程序

我没有改变任何东西,我得到以下错误:

我有一些像这样的javascript函数

function onSelectRow_${itemid}(){
   something;
}

这在firebug脚本选项卡中显示如下

function onSelectRow_87878(){
     something;
}

我在firebug-> script选项卡中放了多个断点(它有超过20行,我把一个ine.).

但问题是,firebug无法调试这些方法,即.它并没有停止执行它像往常一样执行.我多次尝试过.

这是我的实际代码和用法:

function onSelectRow_${escapedId }(rowId){
}


<jqgrid:grid onSelectRow="onSelectDeviceRow_${escapedId }"

你有任何解决方案吗？

我正在尝试连接到我的 docker mongo 映像，我在本地安装了 mongodb，并将 mongodb bin 路径添加到 windows 路径环境变量中。我正在做以下步骤

cd <docker-location>

docker login

docker ps

-- 检查已经运行的 mongo

docker pull myrepo/mymongo-image:1.0
docker run -p 27017:27017 -d --net=host --name=mytestDB myrepo/mymongo-image:1.0

docker logs mytestDB 

输出：MongoDB 开始：pid=6 port=27017 dbpath=/data/db 64-bit host=moby docker ps 输出：

我正在分析我现有的项目,我发现了一些这样的(概念上):

case class AA private(id: String) {}

case class BB(id: String) {}

在我创建了这两个类来观察差异之后.我使用java反编译器分析了他们的java源代码.我没有发现任何不同.

在那里私人的需要是什么.

这有什么重要性.

我有一个json文件看起来像这样:

{
  "employeeDetails":{
    "name": "xxxx",
    "num":"415"
  },
  "work":[
    {
      "monthYear":"01/2007",
      "workdate":"1|2|3|....|31",
      "workhours":"8|8|8....|8"
    },
    {
      "monthYear":"02/2007",
      "workdate":"1|2|3|....|31",
      "workhours":"8|8|8....|8"
    }
  ]
}

我必须从这个json数据中获得工作日期和工作时间.

我试过这样的:

import org.apache.spark.{SparkConf, SparkContext}

object JSON2 {
  def main (args: Array[String]) {
    val spark =
      SparkSession.builder()
        .appName("SQL-JSON")
        .master("local[4]")
        .getOrCreate()

    import spark.implicits._

    val employees = spark.read.json("sample.json")
    employees.printSchema()
    employees.select("employeeDetails").show()
  }
}

我这样得到例外:

Exception in thread "main" org.apache.spark.sql.AnalysisException: cannot resolve '`employeeDetails`' given input columns: [_corrupt_record];;
'Project ['employeeDetails]
+- Relation[_corrupt_record#0] json

我是Spark的新手.

我突然在Jenkins中遇到这个错误:

我了解我现有的项目，有几件事我无法理解：

trait PeriodA {
  def start: Long
  def stop: Long
  def description: String
  def manageTo: String
}

case class PeriodEntity(
  start: Long,
  stop: Long,
  description: String,
  manageTo: String)
  extends PeriodA

你能解释一下这里发生了什么吗？

我正在学习Scala和Akka,我基本上是Java程序员.我看到各种语法,但很少我无法理解.

case class ProcessStringMsg(string: String)
case class StringProcessedMsg(words: Integer)

class StringCounterActor extends Actor {
  def receive = {
    case ProcessStringMsg(string) => {
      val wordsInLine = string.split(" ").length
      sender ! StringProcessedMsg(wordsInLine)
    }
    case _ => println("Error: message not recognized")
  }
}

在这里,是什么意思sender ! StringProcessedMsg(wordsInLine)？
