当多个测试同时运行时，Redis连接关闭

我在一个类中有几个测试用例，只有一个会成功，但所有其他的都失败了，redis池异常。如何确保其他测试也可以从池中获取连接

这是我的控制器类，它将uuid令牌设置为play缓存，play缓存通过play redis插件设置为redis。播放缓存调用RedisPlugin，然后从绝地客户端获取一个池。此控制器类将在所有希望返回身份验证令牌的API中使用

trait Security { self: Controller =>

  implicit val app: play.api.Application = play.api.Play.current

  lazy val CacheExpirationShort =
    this.app.configuration.getInt("cache.expiration").getOrElse(8 * 60 * 60) // 8 hrs

  val AuthTokenCookieKey = "XSRF-TOKEN"

  /* additional methods to handle token passing */
  implicit class ResultWithToken(result: SimpleResult)(implicit req: RequestHeader) {
    def withTokenShort(token: (String, String)): SimpleResult = {
      Cache.set(token._1, token._2, CacheExpiration)
      MemberToken.add(token._2, token._1)
      val isSecure = req.headers.get("X-Scheme").collect {
        case "https" => true } getOrElse { false }
      result.withCookies(Cookie(AuthTokenCookieKey, token._1, Some(CacheExpirationShort), path="/", domain=Some(App.cookieDomainFromHost(req.host)), secure=isSecure , httpOnly=false))
    }
  }
object Security extends Controller with Security

编辑1：

因此，我认为在RedisPlugin，jedisPool应该改为def

 lazy val jedisPool = {
   val poolConfig = createPoolConfig(app)
   Logger.info(s"Redis Plugin enabled. Connecting to Redis on ${host}:${port} to ${database} with timeout ${timeout}.")
   Logger.info("Redis Plugin pool configuration: " + new ReflectionToStringBuilder(poolConfig).toString())
   new JedisPool(poolConfig, host, port, timeout, password, database)
 }

我也有同样的问题，看起来最好的解决方案（只要你不测试Redis本身）就是禁用Redis插件进行测试，让它使用默认缓存

val config = Map(
  "ehcacheplugin" -> "enabled",
  "redisplugin" -> "disabled")

"this test" should {
  "not die" in {
    running(FakeApplication(additionalConfiguration = config)) {
      ...
    }
  }
}

你能发布你在哪里以及如何使用它们吗？@LimbSoup我更新了我的帖子，介绍了我在哪里使用redis插件和绝地。@angelokh我想这是由于一些严重的内存使用。您可以尝试增加jvm的内存分配吗？编译/测试时，请尝试“-Xms512m”或更高版本，如1024/2048。在逃parameter@RGAT否，我尝试导出_JAVA_OPTIONS=“-Xms800m-Xmx1500m-XX:PermSize=64m-XX:MaxPermSize=256m”，然后运行“播放测试”。它不起作用。@angelokh我想你正在使用多线程？
