Java 即使在使用GridFS时，也超出了MongoDB BSON大小

在GridFS MongoDB版本2.4.9中保存文档时，我看到了这个错误

2015-05-15 10:19:15,409 ERROR [STDERR] com.mongodb.MongoInternalException: DBObject of size 160038724 is over Max BSON size 16777216

代码如下：

public void update(String correlatorId, byte[] bytes) {
        Date now = new Date(System.currentTimeMillis());
        if ( gfs )  {
            GridFSDBFile state = gridFs.findOne(correlatorId);
            state.put( correlatorLastModificationDateMappingField, now );
            state.put( correlatorBytesMappingField, bytes );
            state.save();
        } 
    }

感谢您的帮助。 以下是详细的MongoDB信息：

db.runCommand("buildInfo")
{
    "version" : "2.4.9",
    "gitVersion" : "52fe0d21959e32a5bdbecdc62057db386e4e029c",
    "sysInfo" : "Linux ip-10-2-29-40 2.6.21.7-2.ec2.v1.2.fc8xen #1 SMP Fri Nov 20 17:48:28 EST 2009 x86_64 BOOST_LIB_VERSION=1_49",

    "bits" : 64,
    "debug" : false,
    "maxBsonObjectSize" : 16777216,

}

maxBsonObjectSize是仅对集合文档有效还是也处理GridFS

干杯

您正在使用32位mongodb吗？它是64位的。我更新了这个问题。你使用的是什么版本的Java驱动程序？correlatorBytesMappingField与什么相关？这似乎是错误的原因。这真的是元数据还是文件数据？我使用的是2.9.3版本。correlatorBytesMappingField是一个字节数组，它保存我保存在GridFS中的内容。
