Wildfly正常运行，直到在某个时候停止处理请求并显示以下异常：

如果wildfly不处理请求，然后关闭wildfly或尝试测试数据源连接，则还将显示上述有关SQL资源的异常。

下图显示了此数据源连接的统计信息。还可以看到池连接已最大化，并且所有连接都处于活动状态。

Pool connections are maxed out and all of them are active too

当我尝试从wildfly管理员控制台测试数据源连接时，它给了我这个错误： 

Unexpected HTTP response: 500

Request
{
    "address" => [
        ("subsystem" => "datasources"),
        ("data-source" => "betadata")
    ],
    "operation" => "test-connection-in-pool"
}

Response

Internal Server Error
{
    "outcome" => "failed",
    "failure-description" => "WFLYJCA0040: failed to invoke operation: WFLYJCA0047: Connection is not valid",
    "rolled-back" => true
}


我不明白是什么导致了Wildfly中此类行为。

我发现只有在关闭并重新启动Wildfly或仅从Wildfly的管理控制台中刷新所有连接（没有其他刷新策略可用）后，该问题才能解决。

注意：默认情况下，My Wildfly使用standalone.xml作为配置。

最佳答案

我确定问题出在您的代码中。首先检查您的代码是否存在连接泄漏。

关于java - WildFly 10.0.0 Final正在接受请求，但将其放入队列中而不进行处理，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49892634/
