Grails 生成WebApp War文件-将忽略该参数的错误

我正在尝试在Tomcat7上运行一个项目，该项目需要一些插件，并且是用Grails编写的

使用命令grails prod war创建-war会导致一个错误，告诉我不支持[java.util.List]类型的参数

在何处以及如何查看哪些参数受支持以及为什么列表不受支持

包含错误的日志文件如下所示：

我对Grails/Groovy Tomcat WebApp的主题有些陌生 所以我希望这个问题不是很糟糕

你的实际错误是

Unable to load class org.jets3t.service.impl.rest.httpclient.RestS3Service due to missing dependency org/apache/http/client/methods/HttpHead

您需要在类路径中包含httpclient.jar，将其更改为：

def List listFullAccessResources(VsUser loggedInUser, List resultsGoups)

---

警告将消失…

警告接口类型和抽象类类型不支持作为命令对象。投诉，因为控制器操作具有List resultsGoups参数。这是不受支持的

您可以从隐式“params”映射或使用

像这样的

def listFullAccessResources(AccessResourcesCommand cmd) {
}

class AccessResourcesCommand {
    Bar loggedInUser
    List resultsGroups
}

---

谢谢你的快速回复。好的，如果我忽略警告并添加httpclient.jar-错误消息更改为：无法加载类org.jets3t.service.impl.rest.httpclient.RestS3Service，因为缺少依赖项org/apache/http/HttpRequestok还添加了httpcore.jar，修复了错误。。。但是警告仍然存在，或者在方法是内部控制器方法的情况下将其标记为私有。
