我不能说清楚发生了什么，也记不清是否已将2.2.1升级到2.2.2(我的项目是2.2.2)，再加上2-3周前还可以，但我认为这是弄乱我整体的原因之一JSON来自升级？ (我不知道如何降级)，但是我不想弄乱项目中的任何字体。

无论如何，当我调用controller/action时，它将呈现为JSON，但请看一下我的JSON:

像100x这样重复。

{"_ref":"../../../..","class":"proj.State"},"stateId":1,"normalizedName":"Something","capital":false,"name":"Something"},"state":1},{"attached":true,"capital":false,"errors":{"errors":[]},"handler":     
{"class":"org.codehaus.groovy.grails.orm.hibernate.proxy.GroovyAwareJavassistLazyInitializer","entityName":"proj.City","identifier":1,"implementation": 
{"_ref":"../../../../../..","class":"proj.City"},"persistentClass":"proj.City","readOnly":false,"readOnlySettingAvailable":true,"session":{"JDBCContext":         
{"class":"org.hibernate.jdbc.JDBCContext","connectionManager":{"aggressiveRelease":false,"autoCommit":true,"batcher":     
{"class":"org.hibernate.jdbc.BatchingBatcher"},"class":"org.hibernate.jdbc.ConnectionManager","connection":{"autoCommit":true,"catalog":"DEVDB","class":"com.sun.proxy.$Proxy24" 

请您参考如下方法:

来自域的反射(reflection)，发现他一直在从属性address:company.address搜索所有域，并将其呈现为json并给我所有的废话。
