东西没有被冲走。发生的情况的简化示例：

def testDemo() {
    def person = new Person(...)
    person.save(flush: true)

    println "Number of people after save: " + Person.all.size()

    def dummyList = [1, 2, 3, 4, 5]

    GParsPool.withPool { num ->
        println "Number of people after withPool: " + Person.all.size()
        dummyList.eachParallel {
            println "Number of people after eachParallel " + Person.all.size()
            Person.withTransaction {
            ...

输出：

Number of people after save: 1
Number of people after withPool: 1
Number of people after eachParallel: 0

我不知道是否必须对Session和Transaction进行某些操作才能使数据持久化，或者这是GPar中的错误。在底层的hibernate级别发生了什么？

我希望最近创建的Person在并行闭包中可见。
