两种路线:  
第一种是把byte[]转换为List< float >,然后存储到Milvus的floatVector中 第二种是把byte[]转换为ByteBuffer,然后存储到Milvus的BinaryVector中   
 步骤:  
我先用的是第一种,但是在转换float过程中,报错NaN,某些数据无法转换,于是换第二种,伪代码如下   
	
	. . . 
	
	FieldType  fieldType =  FieldType . newBuilder ( ) 
                . withName ( "feature" ) 
                . withDataType ( DataType. BinaryVector ) 
                . withDimension ( 8256 ) 
                . build ( ) ; 
    . . . 
	
	byte [ ]  featureData=  . . . ; 
	
    ByteBuffer  byteBuffer =  ByteBuffer . wrap ( featureData) ; 
    
    byteBuffer. position ( byteBuffer. capacity ( ) ) ; 
    
    List < ByteBuffer >   vector =  new  ArrayList < > ( ) ; 
    vector. add ( byteBuffer) ; 
    List < InsertParam. Field >   fields =  new  ArrayList < > ( ) ; 
    fields. add ( new  InsertParam. Field ( "feature" , vector) ) ; 
	
	InsertParam  insertParam =  InsertParam . newBuilder ( ) 
          . withCollectionName ( collection_name) 
          . withFields ( fields) 
          . build ( ) ; 
    R < MutationResult >   mutationResultR =  milvusClient. insert ( insertParam) ; 
  
 报错:Incorrect dimension for field ‘feature’: the no.0 vector’s dimension: 0 is not equal to field’s dimension: 1032  
解决思路:先百度谷歌,然后没找到解决办法,于是看报错位置,查源码,定位报错原因,如下   然后发现byte[]在经过ByteBuffer byteBuffer = ByteBuffer.wrap(featureData);这段代码转换时,position被默认设置为0,因此加入byteBuffer.position(byteBuffer.capacity());修改position值 还有需要注意的是设置该字段的向量维度时,需要设置为byte[]的长度乘以8
