grails - Grails @Resource在PUT上抛出GroovyCastException

Question

我有以下域对象:

package example.rest

import grails.rest.Resource

@Resource(uri="/departments", formats=['json', 'xml'])
class Department {

String displayName
Integer locationId
Boolean showModal

static mapping = {
    id generator: "assigned"
    table "departments"
    version false
}

static constraints = {
    showModal nullable: true
    displayName nullable: true
    locationId nullable: true
}
}

GET的工作正常，但是PUT抛出以下异常:

ERROR errors.GrailsExceptionResolver  - GroovyCastException occurred when processing        request: [PUT] /example-rest/departments/21
Cannot cast object 'example.rest.DepartmentController$_update_closure7@6e36bf53' with class 'example.rest.DepartmentController$_update_closure7' to class 'example.rest.DepartmentController'. Stacktrace follows:

任何帮助，将不胜感激。

修复http://jira.grails.org/browse/GRAILS-10972时，我遇到了类似的问题。您的问题应该在Grails 2.3.5中解决(将在本周末发布)。由commit https://github.com/grails/grails-core/commit/d073a93b修复。

确保Config.groovy中的grails.mime.types设置也已更新。必须手动完成。参见GRAILS-10973。
