我使用以下代码创建了一个新的 grails 应用程序
grails create-app myapp --profile=rest-api
我修改了ApplicationController并为其添加了命名空间,如下所示:
class ApplicationController implements PluginManagerAware {
/** The Namespace for the version of the API, see http://docs.grails.org/latest/guide/REST.html#versioningResources */
static namespace = "v1"
GrailsApplication grailsApplication
GrailsPluginManager pluginManager
def index() {
[grailsApplication: grailsApplication, pluginManager: pluginManager]
}
}
目录下有一个index.gson
文件views/application/
。
我使用运行此设置grails run-app
并将我的浏览器指向http://localhost:8080
它抛出以下异常:
<=======2020-04-08 16:01:31.616 ERROR --- [nio-8080-exec-1] .a.c.c.C.[.[.[.[grailsDispatcherServlet] : Servlet.service() for servlet [grailsDispatcherServlet] in context with path [] threw exception [Could not resolve view with name 'index' in servlet with name 'grailsDispatcherServlet'] with root cause
但是,如果我修改控制器代码使用render
,一切正常。
render(view:'index',model: [grailsApplication: grailsApplication, pluginManager: pluginManager])
grails -v 的输出 Grails 版本:4.0.2
JVM 版本:1.8.0_171 操作系统:macOS High Sierra
