我想用 grails 测试一个简单的 liferay portlet。
我正在使用： Liferay 版本 liferay-portal-6.1.1-ce-ga2 嵌入了 tomcat 版本 tomcat-7.0.27 ，Grails 2.1.0 ，IDE Groovy/Grails Tool Suite 版本：3.0.0.RELEASE 和JDK1.7.0_05
我安装了plugins.portlets=0.9.2 和 plugins.portlets-liferay=0.4
在项目中安装 grails 插件后，我只需运行以下命令： create-portlet directoryio.testLiferay 和 generate-portlet-views directoryio.testLiferay
我已经像http://grails.org/plugin/portlets-liferay一样配置了 Config.groovy
我的 portlet 类如下所示：
package directorio
导入 javax.portlet.*
类 TestLiferayPortlet {
def title = 'Grails test'
def description = '''Portlet de pruebas.'''
def displayName = 'GrailsTest'
def supports = ['text/html':['view', 'edit', 'help']]
//uncomment to declare events support
//def events = [publish: ["event-1"], process: ["event-2"]]
//uncomment to declare public render parameter support
//def public_render_params = ["prp-1","prp-2"]
// DEFINITIONS FOR liferay-display.xml
def liferay_display_category = 'SCRD'
// DEFINITIONS FOR liferay-portlets.xml
def liferay_portlet_ajaxable = 'true'
def liferay_portlet_header_portlet_css = [
'/css/protoFlow.css'
]
def liferay_portlet_header_portlet_javascript = [
'/plugins/richui-0.5/js/flow/lib/prototype.js',
'/plugins/richui-0.5/js/flow/lib/scriptaculous.js',
'/plugins/richui-0.5/js/reflection/reflection.js',
'/plugins/richui-0.5/js/flow/protoFlow.js'
]
def actionView = {
//TODO Define action phase for 'view' portlet mode
portletResponse.setRenderParameter("prp-1", "value-1");
}
def eventView = {
//TODO Define event phase for 'view' portlet mode.
def eventValue = portletRequest.event.value
}
def renderView = {
//TODO Define render phase for 'view' portlet mode.
//Return the map of the variables bound to the view,
//in this case view.gsp if it exists or render.gsp if not
['mykey':'myvalue']
}
def resourceView = {
//TODO define resource phase for 'view' portlet mode.
//Render HTML as response
render {
html {
head()
body {
"Render me!!"
}
}
}
}
def actionEdit = {
//TODO Define action phase for 'edit' portlet mode
portletResponse.setEvent("event-1","event-1")
portletResponse.setPortletMode(PortletMode.VIEW)
}
def renderHelp = {
//TODO Define render phase for 'help' portlet mode
//Return the map of the variables bound to the view,
//in this case help.gsp if it exists or render.gsp if not
['mykey':'myvalue']
}
def doResource = {
//TODO Define handling for default resource URL handling method, independent of porlet mode
//Return the map of the variables bound to the view,
//in this case resource.gsp
['mykey':'myvalue']
}
//invoked by setting 'action' param in resourceURL (as an example) to 'doSomethingAjaxy'
def doSomethingAjaxy = {
//render JSON
render(contentType:"text/json") {
example(mykey:"myvalue")
}
}
//invoked by setting 'action' param in eventURL (as an example) to 'handleThisEvent'
def handleThisEvent = {
//render thisEvent.gsp
render(view:"thisEvent")
}
}
如果我执行 run-app 和 war，它工作正常。但是，当我将战争放入部署 liferay 目录并启动 tomcat 时，出现错误：
