Question

我想在我的mongo对象中打印_id（$ {oid}。当我打印整个对象时，我可以在对象中看到它，但是当我尝试在我的gsp页面中引用它时，它无法访问它。我不明白为什么？

这是我的控制器方法

    def index_mod(Integer max) {
    MongoClient mongoClient = new MongoClient("localhost", 27017)
        DB chloroKB = mongoClient.getDB("ChloroKB");
    log.debug("DB : " + chloroKB)

    def crossref = chloroKB.getCollection("CrossReference_URL")
    log.debug("crossref : " + crossref)

    def crossrefList = new ArrayList<CrossReference_URL>()
    def crossrefCount = 0
    DBCursor cursor = crossref.find()
    try {
        while(cursor.hasNext()) {
        def nextCrossRef = cursor.next()
        log.debug(crossrefCount + " - " + nextCrossRef)
        crossrefList.add(nextCrossRef)
        crossrefCount++
        }
    } finally {
        cursor.close();
    }

    log.debug("list CrossRef : " + crossrefList)

        params.max = Math.min(max ?: 10, 100)
    model:[count: crossrefCount, crossReferenceList: crossrefList]//CrossReference_URL.list(params)]
   }

这是我想在我的gsp页面中打印它的表：

<table>
      <!-- SBO - test what is in the crossReference_URLInstanceList -->
      <tr><th>crossReference_URLInstanceList : ${crossReferenceList}</th></tr>

      <thead>
    <tr>
      <g:sortableColumn property="crossref_source" title="${message(code: 'crossReference_URL.id.label', default: 'Id')}" />

      <g:sortableColumn property="crossref_source" title="${message(code: 'crossReference_URL.crossref_source.label', default: 'Crossrefsource')}" />

      <g:sortableColumn property="crossref_url" title="${message(code: 'crossReference_URL.crossref_url.label', default: 'Crossrefurl')}" />

      </tr>
      </thead>
      <tbody>
      <g:each in="${crossReferenceList}" status="i" var="list">
    <tr class="${(i % 2) == 0 ? 'even' : 'odd'}">
      <td>${list.id}</td>

      <td><g:link action="show" id="${list._id}">${list.crossref_source}</g:link></td>

    <td>${list.crossref_url}</td>

    </tr>
      </g:each>
      </tbody>
    </table>

有人有想法吗？提前致谢
