Question

我正在玩Play！框架版本2.1.5，在QBox.io上使用Jest 0.0.4和ElasticSearch 0.90.5。

我有以下代码：

try {
    SearchConfig config = new SearchConfig(); 
    JestClient client = config.jestClient();
    Logger.debug("client exists");
    Index index = new Index.Builder(post).index("ads").type("ad").build();
    Logger.debug("index exists");

    client.execute(index);
    Logger.debug("post client.execute()");
} catch (IOException e) {
    e.printStackTrace();
} catch (Exception e) {
    e.printStackTrace();
}

运行时出现以下错误：

[debug] application - client exists
[debug] application - index exists
[debug] application - index: io.searchbox.core.Index@2ddf188f
[error] application -

我是Play和ElasticSearch（和Jest）的新手，我不知道如何解决这个SOError问题。任何帮助表示赞赏！提前谢谢！

Answer 1

增加应用的堆栈大小无济于事？

可以使用jvm选项-Xss4m来完成，其中4m大于os上的默认值。
