在PojoCodec

Question

以下函数中出现异常。

我们有一个由两名成员组成的Pojo

私人地图<字符串，列表> ref;

私有映射<字符串，列表<对象>> myInnerParam;

调试显示以下函数引发异常（CodecConfigurationException）

private void specialize() {
    if (specialized) {  
     codecCache.put(classModel, this);  for 
     (PropertyModel<?> propertyModel : 
     classModel.getPropertyModels()) {  try {  
         addToCache(propertyModel); } catch (Exception e) 
       { 
         throw new 
          CodecConfigurationException(format("Could not 
          create a PojoCodec for '%s'."  + " Property '%s' 
          errored with: %s", classModel.getName(), 
          propertyModel.getName(), e.getMessage()), e);  }  
        }  
        }
     }

上述函数中PropertyModel的值。

propertyModel = {PropertyModel@10278} "PropertyModel{propertyName='myInnerParam', readName='myInnerParam', writeName='myInnerParam', typeData=TypeData{type=Map, typeParameters=[String, List<Object>]}}"

name = "myInnerParam"

readName = "myInnerParam"

writeName = "myInnerParam"

typeData = {TypeData@10350} "TypeData{type=Map, typeParameters=[String, List<Object>]}"

codec = null

propertySerialization = {PropertyModelSerializationImpl@10351}

useDiscriminator = null

propertyAccessor = {PropertyAccessorImpl@10352}

cachedCodec = null

例外

e = {CodecConfigurationException@11668} "org.bson.codecs.configuration.CodecConfigurationException: Can't find a codec for class java.lang.Object."
 detailMessage = "Can't find a codec for class java.lang.Object."
 value = {char[46]@11905} 
 hash = 0
 cause = {CodecConfigurationException@11668} "org.bson.codecs.configuration.CodecConfigurationException: Can't find a codec for class java.lang.Object."
 detailMessage = "Can't find a codec for class java.lang.Object."
 cause = {CodecConfigurationException@11668} "org.bson.codecs.configuration.CodecConfigurationException: Can't find a codec for class java.lang.Object."
 stackTrace = {StackTraceElement[0]@11901} 
 suppressedExceptions = {Collections$UnmodifiableRandomAccessList@11902} size = 0
 stackTrace = {StackTraceElement[0]@11901} 
 suppressedExceptions = {Collections$UnmodifiableRandomAccessList@11902} size = 0

这对我们来说是一个障碍-我们无法前进。您能否建议解决方法-如果要花很长时间解决这个问题。
