RE: specify typehandler for byte[]

This is the javaType that works in the sqlmap but not in the sqlconfig – [B

I will try [Ljava.lang.Byte

Guess I forwarded an incomplete thread:

Well, I learned something new today – the internal representation of class names. This mapping does not fail like before:

But it is not being called for my byte[] properties. The existing byte array type handler is instead. Any clues as how to fix this?

Andres,

I think you might have your javaType attribute wrong. Can you try "[Ljava.lang.Byte" and let me know if that works for you.

I want to emphasize that this works when I specify the handler per column in the sqlmap parameter map because I don’t need to specify the javaType there. But I want to specify it globally, so I don’t have to create parameterMaps and typeHandler declarations for every column.

My class has a property like this:

Private ds byte[ ]

The db tables are like this:

CREATE TABLE bugs.x86_seg_reg

(

id int8 NOT NULL DEFAULT nextval('x86_seg_reg_id_seq'::regclass),

ds numeric(16) NOT NULL,

es numeric(16) NOT NULL,

fs numeric(16) NOT NULL,

gs numeric(16) NOT NULL,

CONSTRAINT x86_seg_reg_pkey PRIMARY KEY (id)

)

The sql created from the default type handler does setBytes() but Postgres interprets that as a bytea column type. So I created my own type handler:

typeHandler =jdbcType"NUMERIC" =/>

typeHandler jdbcType=javaType="com.soe.freerealms.dao.ibatis.ByteArrayBigDecimalTypeHandler"
