Grails中的REST跳转

Grails中自动生成的controller所实现的CRUD， 基本上是index/create/save/update/delete/show等几个方法，其中create，edit等执行后自动跳转到show， 这一跳转的关键是

8.1.5.1 Extending the RestfulController super class

 

The easiest way to get started doing so is to create a new controller for your resource that extends the grails.rest.RestfulController super class. For example:

class BookController extends RestfulController {

    static responseFormats = ['json', 'xml']

    BookController() {

        super(Book)

    }

}

To customize any logic you can just override the appropriate action. The following table provides the names of the action names and the URIs they map to:

 

HTTP MethodURIController Action

GET/booksindex

GET/books/createcreate

POST/bookssave

GET/books/${id}show

GET/books/${id}/editedit

PUT/books/${id}update

DELETE/books/${id}delete

 

update中决定跳转方向的代码是

 

request.withFormat {

            form multipartForm {

                flash.message = message(code: 'default.updated.message', args: [message(code: 'QuantityUnit.label', default: 'QuantityUnit'), quantityUnitInstance.id])

                redirect (controller: "unitManager", action: "show", params: [id: quantityUnitInstance.id])

            }

            '*'{ redirect quantityUnitInstance, [status: OK] }

        }

下划线部分决定跳转的方向

 

自动生成的是这样的：

                redirect systemRoleInstance

为了自己的需要，被改成了上述样子——关键是改变了控制器。
