grails - MongoDB集合访问

Question

我将MongoDB专门用于Grails REST应用程序和以下所示的域。此响应 call 失败:

@Secured(['permitAll'])
def index() {
    respond Person.list()
}

与错误

ERROR errors.GrailsExceptionResolver  - IllegalAccessException occurred when processing request: [GET] /teesheet/person
Class org.codehaus.groovy.grails.web.converters.marshaller.json.GroovyBeanMarshaller can not access a member of class java.util.Collections$UnmodifiableCollection with modifiers "public". Stacktrace follows:
Message: Class org.codehaus.groovy.grails.web.converters.marshaller.json.GroovyBeanMarshaller can not access a member of class java.util.Collections$UnmodifiableCollection with modifiers "public"

尝试将集合转换为JSON也会失败，并显示相同的错误。

def personList = Person.list() as JSON

low level API有效。

package com.tworks.teesheet

import grails.rest.Resource

class Person {
  String name
  String firstName
  String lastName
  String email

  User userPerson

  TimeZone timeZone = TimeZone.getTimeZone("America/Los_Angeles")
  Date dateCreated = new Date()
  Date dateModified = new Date()
}

假设您使用的是Mongo for Grails插件，则域类需要@Entity ...

import grails.persistence.Entity

@Entity
class Person {
  static mapWith = "mongo"

  String name
  String firstName
  String lastName
  String email

}

我添加了mapWith="mongo"，因为我不确定您是否在mongo插件旁边使用了hibernate插件；如果不是，请删除休眠模式，否则，它可能为interfere。
