我有一个grails 3.1.12应用程序，使用Oracle DB。当运行以下代码片段1和代码片段2时，我收到 "PooledConnection has already been closed "异常。代码snippet1和代码snippet2工作，并间歇性地给出PooledConnection已关闭异常。一些stackoverflow的链接建议将数据源类型改为c3P0解决了这个问题，但这对我来说并不奏效。我试图了解是什么原因导致这个问题，任何建议如何解决这个问题？
Snippet1 :
class HistoryService {
static transactional = false
def manualHistoryLog(def originalObject, def newObject, def mode, def simpleName, def objectId, def refObject){
//.............//
addObject(newObject, false)
}
@Transactional(propagation=Propagation.REQUIRES_NEW, rollbackFor=Exception.class)
public addObject(def newObject, def booleanVal)
{
try {
log.info("Start of solrIndexService.addObject")
solrIndexService.addObject(newObject, booleanVal)
log.info("End of solrIndexService.addObject")
}
catch(e) {
log.error("error adding object", e)
}
}
}
请注意，我最近添加了@Transactional(propagation=Propagation.REQUIRES_NEW)在上面的方法addObject()，但仍然没有运气，并得到Pooled closed connection异常。
Snippet 2 :
class ActionLogService {
def saveActionLog(def actionLog,def eventName,def saveToSolr) {
try{
log.debug( "Solr Indexing :::: START")
solrIndexService.addObjectFetch(actionLog, false)
log.debug( "Solr Indexing :::: END")
}catch (IOException e) {
log.error ("IO error thrown while indexing", e)
}catch(Exception e){
log.error ("error thrown while indexing", e)
}
}
}
###环境信息
在application.groovy中配置了DataSource。
dataSource {
dbCreate = 'None'
pooled = true
dialect = org.hibernate.dialect.Oracle10gDialect
type = "javax.sql.DataSource" //required
auth = "Container" // optional
description = xxxxxxxxxxxxxxxxxxx
driverClassName = "oracle.jdbc.OracleDriver"
url = xxxxxxxxxxxxxxxxxxxxxxxx
username = xxxxxxxxxxxxxxxxx
password = xxxxxxxxxxxxxxxxxx
properties
{
maxActive = "25"
maxIdle = "25"
maxWait: "3000"
minEvictableIdleTimeMillis = "60000"
timeBetweenEvictionRunsMillis = "60000"
}
}
Pooled连接关闭异常的完整栈跟踪。

当把连接作为参数传递给一个函数时，我得到了这个异常。另起炉灶.我的解决方案是传递dataSource并在函数中实例化一个新的连接。
