我在 Windows 7 64 位上使用 Grails 2.5.1，在使用 Grails 命令生成控制器和视图之后

generate-all "*"

当我在控制器中添加任何新行时，出现以下错误：

编译错误：启动失败：E:\Development\eclipse\TekDays\grails- app\controllers\com\tekdays\TekEventController.groovy:47：不明确的表达式可能是一个无参数的闭包表达式，一个孤立的开放代码块，或者它可能会继续前一条语句；解决方案：添加一个显式参数列表，例如 {it -> ...}，或者通过给它一个标签来强制它被视为一个开放块，例如 L:{...}，或者删除前一个换行符，或添加显式分号 ';' @ 第 47 行，第 4 列。{ ^ 1 错误

这是我的控制器：

package com.tekdays

import static org.springframework.http.HttpStatus.*

@Transactional(readOnly = true)
class TekEventController
{
def taskService // this what i added
static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]

def index(Integer max)
{
    params.max = Math.min(max ?: 10, 100)
    respond TekEvent.list(params), model:[tekEventInstanceCount: TekEvent.count()]
}

def show(TekEvent tekEventInstance)
{
    respond tekEventInstance
}

def create()
{
    respond new TekEvent(params)
}

@Transactional
def save(TekEvent tekEventInstance)
{
    if (tekEventInstance == null)
    {
        notFound()
        return
    }

    if (tekEventInstance.hasErrors())
    {
        respond tekEventInstance.errors, view:'create'
        return
    }

    tekEventInstance.save flush:true
    taskService.addDefaultTasks(tekEventInstance) // this what i added
    request.withFormat
    {
        form multipartForm
        {
            flash.message = message(code: 'default.created.message', args: [message(code: 'tekEvent.label', default: 'TekEvent'), tekEventInstance.id])
            redirect tekEventInstance
        }
        '*' { respond tekEventInstance, [status: CREATED] }
    }
}

def edit(TekEvent tekEventInstance)
{
    respond tekEventInstance
}

@Transactional
def update(TekEvent tekEventInstance)
{
    if (tekEventInstance == null)
    {
        notFound()
        return
    }

    if (tekEventInstance.hasErrors())
    {
        respond tekEventInstance.errors, view:'edit'
        return
    }

    tekEventInstance.save flush:true

    request.withFormat
    {
        form multipartForm
        {
            flash.message = message(code: 'default.updated.message', args: [message(code: 'TekEvent.label', default: 'TekEvent'), tekEventInstance.id])
            redirect tekEventInstance
        }
        '*'
        {
            respond tekEventInstance, [status: OK]
        }
    }
}

@Transactional
def delete(TekEvent tekEventInstance)
{

    if (tekEventInstance == null)
    {
        notFound()
        return
    }

    tekEventInstance.delete flush:true

    request.withFormat
    {
        form multipartForm
        {
            flash.message = message(code: 'default.deleted.message', args: [message(code: 'TekEvent.label', default: 'TekEvent'), tekEventInstance.id])
            redirect action:"index", method:"GET"
        }
        '*'
        {
            render status: NO_CONTENT
        }
    }
}

protected void notFound()
{
    request.withFormat
    {
        form multipartForm
        {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'tekEvent.label', default: 'TekEvent'), params.id])
            redirect action: "index", method: "GET"
        }
        '*'
        {
            render status: NOT_FOUND
        }
    }
}
}

有什么建议可以解决这个错误吗？谢谢
