chalice 。无法解析名称为 'index' 的 servlet 中名称为 'grailsDispatcherServlet' 的 View

Question

我正在开始使用 Grails (3.x) Framework，但在尝试将域内容呈现到 View 时遇到了此错误:

Error 500: Internal Server Error
URI /hello/index
Class javax.servlet.ServletException
Message: Could not resolve view with name 'index' in servlet with name 'grailsDispatcherServlet'

HelloController.groovy:

package helloworld   
class HelloController {

    def index() {
        def Person persona1 = new Person(firstName: "someone", lastName: "stuck", age: 21)
        [persona:persona1]
    }
}

Person.groovy:

package helloworld

class Person {
    String firstName
    String lastName
    int age
}

Answer 1

确保grails-app/views/hello/index.gsp 文件存在。
