Question

我已经在grails 2.4.2中安装了可搜索的插件。

compile ":searchable:0.6.9"

它已成功安装，但是当我运行该应用程序时，它会出现此错误。我没有制作任何控制器。只有一个被声明为可搜索的域类。如何解决这个问题？

Answer 1

您可以尝试使用安装可搜索插件的命令行。

grails install-plugin searchable（我假设你使用的是java 1.5 +）

安装插件后，尝试让您的域可搜索，因为我相信在安装过程中会创建可搜索的控制器和服务类。

Answer 2

您使用的是什么版本的Hibernate插件？请注意，Searchable插件不适用于Hibernate 4;你必须使用Hibernate 3。
