play2弹性搜索示例不适用于play2.1.3 [英] play2-elasticsearch example is not working with play2.1.3

问题描述

我正在尝试使用play2-popsearch plugin for playframework2 2.1.3
我刚刚完成了github的例子说，唯一的修改是改变这一行来使用本地ip地址上的服务器。

  elasticsearch.client =127.0.0.1:9300
  

但是当我尝试运行这个例子，我得到以下异常，任何想法？
我正在使用play框架2.1.3在mac上与jdk1.7

解决方案

跟踪，似乎你使用 0.5.4 版本与播放2.1.3不兼容（仅播放2.1.0）。

如果你看README文件中的版本表，您将看到 0.7-SNAPSHOT 版本是必需的，如果您使用播放2.1.3。尝试使用这个。

I'm trying to use play2-elasticsearch plugin for playframework2 version 2.1.3 I have just done exactly the github example says, the only modification was to change this line to use the server on the local ip address.

elasticsearch.client="127.0.0.1:9300"

but when i try to run the example i get the following exception, any idea? I'm using play framework 2.1.3 on mac with jdk1.7

解决方案

From the stack trace, it seems that you use the 0.5.4 version which is not compatible with play 2.1.3 (only with play 2.1.0).

If you look at the "versions" table in the README file, you will see that the 0.7-SNAPSHOT version is required if you use play 2.1.3. Try to use this one.
