我正在将我的应用程序从 Grails 2.1 迁移到 2.3。迁移后我遇到了很多错误——我想要一些带有 Grails 2.3 和 Spring 集成的示例应用程序。
我做了一些 HelloWorld 示例应用程序,它们运行良好。但即使我在我的应用程序中应用了同样的东西,甚至在一些地方它给出了错误。因为我的应用程序非常大(100mb),而且我使用了大量与 Spring、Hibernate 和许多 Grails 插件的集成。
我没有找到任何类似“从 Grails 2.1 迁移到 Grails 2.3”的代码级文档。我无法从 Grails 或在线找到任何示例应用程序。
Grails 官方文档,都是关于提供 Grails META 信息的。
在我的 main.gsp 229 行中:
<g:include controller="filter" action="tree"/>
